My Hypertension Exercise Program Review

Highly Recommended

Recently several visitors of websites have asked me about this book, which is being advertised quite widely across the Internet. So I decided to buy a copy myself to figure out what all the excitement was about.

My opinion on this e-book is, if you do not have this e-book in your collection, your collection is incomplete. I have no regrets for purchasing this.

High Blood Pressure Hypertension

High blood pressure (hypertension) is dangerous. If blood pressure is high, the heart has to work harder to pump the same amount of blood, which puts a great stress on the cardiovascular system. Patients with high blood pressure are more prone to heart attacks, heart failure, kidney failure, and strokes. Fortunately, blood pressure can be controlled with appropriate medications and lifestyle modifications, greatly reducing the risk of complications. Some measures that help to control high blood pressure include stopping smoking, losing excess weight, avoiding excessive salt, and exercising at least three to four times a week.

What Exactly Is High Blood Pressure

When your heart beats, it pumps blood into your arteries and creates a pressure within them. High blood pressure (also known as hypertension) occurs when too much pressure is placed on the walls of the arteries. This can occ if there is an increase in blood volume or the blood vessels themselves constrict or narrow. Hypertension is the medical term for sustained high blood pressure. It has nothing to do with being tense, nervous, or hyperactive.

Mechanism of Abnormal JVF Patterns and Contours in Pulmonary Hypertension

The majority of patients with abnormal flow patterns and pulmonary hypertension had increased RA v wave pressure, implying that the Df velocity was increased (exaggerated y descent). The increased v wave pressure was shown to be a result of an increased RV early diastolic and pre-a wave pressure. The incidence of congestive heart failure was higher in patients with Sf < Df and Df alone compared to the pattern of Sf Df. This indicated that decreased RV systolic function (decreased x' descent) also played a part. This seems to be a later phenomenon in serial observations (41) (Fig. 18).

Systemic Hypertension

On the basis of its prevalence in the aging population and the direct pathophysiologic links of elevated blood pressure to atherosclerosis, stroke, MI, sudden death, and heart failure, hypertension is the most important population-attributable and modifiable risk factor for cardiovascular events.2 Sustained lowering of arterial pressure is the major and critical mechanism by which antihypertensive therapies reduce the incidence of adverse cardiovascular events.3,4 With the establishment of the importance of blood pressure reduction, the field has matured to the point that placebo-controlled trials in hypertension are considered unethical. To attempt to demonstrate the importance of a specific compound, contemporary trials usually compare different classes of antihypertensive agents. Figure 12-2. Meta-analysis of outcomes of hypertensive patients treated with different antihypertensive agents. Blood pressure (BP)-lowering regimens are based on different drug classes. Mean BP difference...

Secondary Idiopathic Intracranial Hypertension IIH Pseudotumor Cerebri

Normal cerebrospinal fluid (CSF) pressure ranges from 70 to 200 mm of H2O. Elevated intracranial hypertension may be idiopathic or due to secondary causes. Secondary causes for increased intracranial pressure are listed in Table 5.1. Once secondary causes of raised intracranial pressure are excluded, the diagnosis of idiopathic intracranial hypertension (pseudotumor cerebri, IIH) can be made on the basis of headache, papilledema, and other symptoms consistent with raised intracranial pressure. As noted above, IIH was previously referred to as benign intracranial hypertension, as well as pseudotumor cerebri. Diagnostic criteria for IIH are listed in Table 5.2.

Gestational Hypertension

Gestational hypertension is defined as systolic BP of 140 mm Hg or greater and or a diastolic BP of 90 mm Hg or greater, in the absence of proteinuria, in a previously normotensive pregnant woman at or after 20 weeks of gestation. Gesta-tional hypertension is considered severe with sustained elevations in systolic BP of 160 and or diastolic of 110 mm Hg or greater. Women with BP greater than 140 90 mm Hg without proteinuria or end-organ damage may ultimately develop preeclampsia. These initially normotensive women usually become hypertensive late in pregnancy, during labor, or within 24 hours postpartum and note a return to normal BP within 10 days postpartum. If preeclampsia does not develop, the diagnosis of gestational hypertension is made. The diagnosis of gestational hypertension is a temporary one and should be used during pregnancy only in women who do not meet criteria for preeclampsia or chronic hypertension.

Primary Pulmonary Hypertension

Pulmonary arterial pressure was measured in 1852,6 but a century then elapsed before cardiac catheterization set the stage for studying the physiology of lesser circulation. Elevated pulmonary arterial pressure, or pulmonary hypertension, results from disorders of the pulmonary vascular bed, the pulmonary parenchyma, and ventilation (Table 14-1).60 This chapter focuses on the pulmonary vascular bed, specifically on primary pulmonary hypertension, a disorder that originates in the terminal muscular pulmonary arteries and arterioles. The earliest description of idiopathic pulmonary hypertension was an 1891 report of the cardiac pathology in a patient with pulmonary artery sclerosis and right ventricular hypertrophy of unknown cause.107 Primary pulmonary hypertension, a term coined by Dresdale in 1951, referred to an idiopathic disorder residing in the terminal pulmonary arteries and arterioles of three young women.23 These age and sex patterns young and female have been borne out. A...

Arterial Hypertension

In 1958, Hellstrom and associates27 suggested a relationship between hypertension and PHPT these authors reported that 53 of their 95 patients had blood pressures of 150 100 mm Hg or greater. Several series have quoted a prevalence ranging from 21 to 57 (Table 42-3).2833 This wide range may be a result of different patient ages as well as different definitions of hypertension. Lafferty31 showed that hypertension Hypertension (> 165 95 mm Hg) was twice as common among hyperparathyroid patients compared with the general population.8,33 PHPT and hypertension are associated with an increased risk of cardiovascular disease and possibly stroke.34 Bostrom and Alveryd34 as well as Palmer and colleagues35 reported a higher mortality rate (61 ) mainly because of cardiovascular disease in patients with hypercalcemia and PHPT. Unfortunately, hypertension failed to improve in 92 after parathyroidectomy.31 The pathogenesis of hypertension in patients with PHPT has not been completely defined....

TABLE 711 Cl Resistant Metabolic Alkalosiswith Hypertension Elevated Aldosterone Levels

The most common cause of Cl--resistant metabolic alkalosis with associated hypertension is renovascular disease Recent data suggest that primary aldosteronism may occur in as many as 8 of adult hypertensive patients many of these patients do not have a significant metabolic alkalosis

TABLE 715 ClResistant Metabolic Alkalosiswith Hypertension Suppressed Aldosterone Levels Inherited Disorders

Most common monogenic disorder associated with severe early onset hypertension Diagnosis should be entertained in those whose family members also have difficult to control hypertension Metabolic alkalosis, hypokalemia, and severe hypertension are characteristic Presents with severe early onset hypertension and hypokalemia Associated with hypertension, metabolic alkalosis, androgen excess, and virilization

Dyslipidemia Hypertension and Atherosclerosis

The unexpectedly negative outcomes of diabetic studies targeting hyperglycemia as a cardinal risk factor for progression of atherosclerosis emphasize the need to correct dyslipidemia and hypertension typical of the type 2 diabetic state. Dyslip-idemia occurs chiefly when beta cells are unable to maintain the high insulin levels required to inhibit lipolysis from adipose cells. The resulting free fatty acidemia associated with high insulin levels causes the liver to repackage these energy substrates into more triglyceride-rich lipoproteins. Hyperinsulinemia has also been associated with hypertension, changes in vascular responsiveness (endothelial dysfunction), and appearance of inflammatory proteins, especially C-reactive protein. The precise causal factor in these relationships and relative importance of these changes are not well understood.

Idiopathic Intracranial Hypertension IIH Pseudotumor Cerebri

Patients with idiopathic intracranial hypertension (IIH) present with severe headache and have papilledema on examination. These patients are at risk for visual loss and other cranial nerve dysfunction due to elevated intracranial pressure. The diagnosis is confirmed by measuring the opening CSF pressure during lumbar puncture.

Outcome Risk Factors for Postoperative Persistent Hypertension

In our 216 patients with primary hyperaldosteronism. Five patients had persistent hyperaldosteronism after unilateral adrenalectomy. These included three with idiopathic hyperaldosteronism who were thought to have an adenoma before surgery, one who was thought to have primary adrenal hyperplasia without a concurrent adenoma, and another with an aldosterone-producing carcinoma. Another patient had bilateral macronodular hyperplasia and eventually underwent bilateral adrenalectomy that resulted in resolution of both the hyperaldosteronism and hypertension. The long-term cure rate of hypertension by unilateral adrenalectomy for patients with primary hyperaldosteronism averages 69 in reported series.12 In our present series of 210 patients with aldosterone-producing adenoma, 60 became normotensive (defined as a blood pressure lower than 140 90 mm Hg) without medication, and 40 improved markedly but have remained hypertensive since the operation. The incidence of persistent hypertension in...

Mutations That Lower Blood Pressure

A host of mutations that lower blood pressure have also been identified and act to lower net renal salt reabsorption. Homozygous loss-of-function mutations in ENaC subunits result in impaired renal salt handling, causing the recessive form of pseudohypoaldosteronism type I, an often fatal disease of newborns featuring profound in-travascular volume depletion with impaired ability to secrete K+ and H+ (Chang et al. 1996). In these children, salt depletion activates the renin-angiotensin system however, this fails to increase salt reabsorption because the key target, ENaC, is missing. Thus, gain-of-function mutations in ENaC cause hypertension, whereas loss-of-function mutations in this same channel cause life-threatening hypotension. There is also an autosomal dominant form of this disease, which is caused by heterozygous loss-of-function mutations in the mineralocorticoid receptor (Geller et al. 1998). Interestingly, although patients with both forms of this disease can be severely...

Hypertension The Pressures On

When the pressure is on, does your blood pressure rise It probably does. It's normal to have blood pressure rise and fall throughout a day of changing activities and emotions. The problem comes when the force of blood pushing against your arterial walls remains consistently high, as in hypertension. Blood pressure is measured by a sphygmomanometer. A normal reading is about 120 80 a reading of 140 90 measured at least on two office visits is officially considered high blood pressure. Hypertension rarely exhibits symptoms, so it's often called the silent killer. Left untreated, high blood pressure can lead to serious conditions such as vision problems, heart attack, stroke, or kidney failure. If early symptoms do occur, they may include headaches, sweating, muscle cramping, palpitations, rapid pulse rate, dizziness, vision problems, or shortness of breath. Having your blood pressure checked every four to six months is an easy precaution to ensure your pressure is staying on course.

Oxidative Stress in Hypertension Associated ED

Approximately 30 of male hypertensive patients have ED 66 . Despite many epidemiologic studies showing the link between hypertension and ED, scientific studies establishing the cellular and molecular mechanisms of hypertension-associated ED are sparse. Angiotensin II is a potent vasoconstrictor implicated in the development and maintenance of hypertension. Within the vascular wall, angiotensin II acting through the angiotensin I (AT1) receptor stimulates the production of ROS by activation of NADPH oxidase 67 . The corpus cavernosum of hypertensive rats exhibits increased lipid peroxidation 68-70 . Protein expressions of NADPH oxidase sub-units p47phox 71 and gp91phox 70 are upregulated in hypertensive rat penis in parallel with increased oxidative stress and ED. Furthermore, apocynin, an inhibitor of NADPH oxidase, reduces oxidative stress and improves erectile function in hypertensive rats 71 implying a major role for NADPH oxidase in ROS production. More studies are needed to...

Idiopathic Intracranial Hypertension

The pathophysiology of IIH is unknown. Postulated mechanisms include increased CSF production, decreased CSF absorption, and increased venous sinus pressure. Some studies suggest that interstitial brain edema and a decreased rate of absorption at the arachnoid villi are the major contributors. The disturbances of CSF hydrodynamics in IIH persist for years. y Increased CSF pressure in IIH may result from a rise in venous sagittal sinus pressure secondary to extracellular edema causing venous obstruction, or from low conductance for CSF reabsorption producing a compensatory increase in CSF pressure. Patients were evaluated with cerebral venography and manometry, and they demonstrated elevated venous pressure in the superior sagittal and proximal transverse sinuses. This elevated pressure dropped at the level of the lateral third of the transverse sinus resembling a mural thrombosis on venography. Two patients with intracranial hypertension due to...

Malignant Hypertension 1993

Dopamine was given but discontinued when her pressure reached 237 113 mmHg. However, the maximum level of blood pressure later recorded was 256 126 mmHg. She then had a cerebral hemorrhage, and soon after this she died. Her estate started a legal action against 55 defendants, but only three defendants remained shortly after the trial started in 2000. These were her obstetrician, her internal medicine physician, and her intensivist. In his final judgment, the judge said of the internal medicine physician's testimony 'It reflects a triumph of tactics over truth. He is not credible.' He found all three defendant doctors guilty of negligence, and he reserved judgment on the amount of damages to be awarded to the deceased patient's estate28.

Treatment Of Cirrhosis Portal Hypertension And Complications

PMH Hypertension x 15 years, acute pancreatitis x 2 episodes PSH No surgeries FH Father with cirrhosis, died at age 45 from coronary disease mother alive at age 62 with type 2 diabetes mellitus, hypertension, hyperlipidemia, and gastroesophageal reflux disease Drug therapy targeted to reduce portal hypertension and cirrhosis can alleviate symptoms and prevent complications but cannot reverse cirrhosis. Drug therapy is available to treat the complications of ascites, varices, SBP, HE, HRS, and coagulation abnormalities. Portal Hypertension Nonselective ft-blockers such as propranolol and nadolol are first-line treatments to reduce portal hypertension. They reduce bleeding and decrease mortality in patients with known varices. Use of ft-b lockers for primary prevention of variceal formation is controversial. Only nonselective P-blockers reduce bleeding complications in patients with known varices. Blockade of P1 receptors reduces cardiac output and splanchnic blood flow. P2-Adrenergic...

Drugs Used For The Treatment Of Hypertension

A wide variety of drugs are used to treat hypertension, including a- and p blockers, diuretics, calcium channel blockers, ACE inhibitors, AT -receptor antagonists, and vasodilators (Table 7.16). Non-pharmacological strategies include weight reduction, a decrease in alcohol intake and the institution of a low-sodium (with or without high potassium) diet with regular exercise. If these measures fail, drug therapy is indicated. Recent guidelines from the UK and the USA have emphasized the need for antihypertensive treatment in patients with a sustained systolic pressure 2 160 mmHg or sustained diastolic pressure a 100 mmHg. Drug treatment may also be indicated in cases where sustained systolic and diastolic pressures are a 140 and 2 90 mmHg, respectively, in the presence of diabetes, end-organ damage or cardiovascular disease. Individual antihypertensive drugs have similar efficacy when used in isolation, but therapy with a single drug may only be adequate in 50-60 of patients. Combining...

Loud P2 Pulmonary Hypertension Mp3

Clinical Features of Left Atrial and Pulmonary Hypertension Symptoms of pulmonary hypertension Signs of pulmonary hypertension Symptoms of Pulmonary Hypertension When pulmonary hypertension is severe, the vascular changes that develop in the pulmonary arterial bed not only raise the pulmonary vascular resistance but also act as severe obstructive lesion peripherally reducing flow and output. This is further aggravated when the right ventricle becomes decompensated. The main symptoms of pulmonary hypertension are therefore one of low output. The output may become relatively fixed and fail to increase with exertion and may actually paradoxically fall, causing symptoms of presyncope and or syncope with exertion. The oxygen saturation may also fall with exertion. The hypoxemia may also predispose to the development of arrhythmias. Often patients may also complain of vague atypical chest pain. The cause of this is not easily explainable (Table 14). Signs of Pulmonary Hypertension Pulmonary...

Hypertension smoking alcohol cholesterol and drugs

Hypertension is the most common risk factor for spontaneous intracerebral hemorrhage and the frequency has been estimated to be between 70 and 80 . The causative role of hypertension is supported by the high frequency of left ventricular hypertrophy in autopsy of patients with ICH. The role of hypertension and the beneficial effect of antihypertensive treatment with regard to risk of ICH were verified in several large clinical trials. In the PROGRESS trial 21 the relative risk of ICH was reduced by 76 in comparison with the placebo-treated group after 4 years of follow-up. Other risk factors for ICH in addition to old age, hypertension and ethnicity include cigarette smoking and excessive alcohol consumption. Both the Physicians' Health Study and the Women's Health Study 22, 23 confirmed the role of smoking as a risk factor for ICH. For men smoking 20 cigarettes or more the relative risk of ICH was 2.06 (95 CI 1.08-3.96) and for women smoking 15 cigarettes or more the relative risk...

TABLE 716 ClResistant Metabolic Alkalosis without Hypertension

Characterized by hyperreninemia, hyperaldosteronemia in the absence of hypertension or Na+ retention Patients are initially subdivided based on the presence or absence of hypertension those patients with hypertension can then be further categorized based on their renin and aldosterone concentrations


The mild increase in arterial pressure, which occurs in the setting of PaO2 pneumoperitoneum of 15 mmHg in a healthy patient, is not problematic. Clinically significant hypertension during laparoscopy may be due to pneumoperitoneum-related causes such as hypervolemia (fluid overload in the setting of oliguria), hypoxemia, hypercap-nia, or moderately increased intra-abdominal pressure. Hypertension in this setting is a clue to look for these other problems, and the underlying cause, rather than the hypertension itself, should be addressed first.

Chronic Hypertension

Historically, there have been many classifications of hypertension in pregnancy with no apparent consensus. In this chapter we use the now-accepted classification as developed by the National Institutes of Health (Report of the National High Blood Pressure Education Program Working Group on High Blood Pressure in Pregnancy). Hypertension during Chronic hypertension Preeclampsia eclampsia Preeclampsia superimposed on chronic hypertension Gestational hypertension 1. Transient hypertension of pregnancy if preeclampsia is not present at delivery and blood pressure returns to normal by 12 weeks postpartum. 2. Chronic hypertension if the elevation persists. pregnancy is categorized as (1) preeclampsia eclampsia, (2) gestational hypertension, (3) chronic hypertension, or (4) preeclampsia superimposed on chronic hypertension (Box 21-5). These categories identify different disorders that at times overlap but with different epidemiologic characteristics, pathophysiology, and risks for mother...

JM is a 69-year-old Hispanic male who understands English, speaks English fairly well, but does not read. He came into the Geriatric Primary Care Clinic for a cholesterol screening because he has been eating bad food for over 10 years and not exercising. He smokes one pack of cigarettes and drinks two to three beers a day. He takes a baby aspirin daily ever since he suffered a mini-stroke 2 years ago. His other medical conditions include hypertension, arthritis, chronic obstructive pulmonary disease, allergies, and Parkinson's disease. He was hospitalized for pneumonia 2 months ago. He takes nine chronic medications including his inhalers.

Associated Medical Findings

Beyond measuring vital signs and detecting evidence of trauma, the general physical examination is most important for clues to systemic disorders that may alter consciousness. In the initial evaluation, detection of nuchal rigidity and skin lesions are the most important portions of the examination, because they may indicate the presence of bacterial meningitis (or, with nuchal rigidity, either subarachnoid hemorrhage or cerebellar tonsillar herniation). Other points of importance include evidence of hepatic disease, especially jaundice and signs of portal hypertension. An irregular cardiac rhythm raises the suspicion of systemic embolism, which may alter consciousness by producing a brain stem infarct or large bilateral cortical infarcts. Hematomas or purpura raise the possibility of platelet or coagulation disorders and may be associated with intracranial bleeding or conditions such as thrombotic thrombocytopenic purpura. Edema may reflect cardiac, hepatic, renal, or nutritional...

What are the potential consequences of untreated spinal deformities

The consequences depend on many factors, including age, underlying health status, deformity etiology, deformity magnitude, and the potential for future progression of the deformity during the patient's lifespan. Potential consequences of untreated spinal deformity may include cosmetic problems, pain, neurologic deficit, postural difficulty, and impairment in activities of daily living. Severe thoracic deformity may impair respiratory mechanics with resultant hypoxemia, pulmonary hypertension, cor pulmonale, or even death.

Elevated Intracranial Pressure and Cerebral Ischemia

In a small study of pigs insufflated with CO2 at a pressure of 15 mmHg, the intracranial pressure increased by 5 mmHg (169). In two myelomeningocele patients with ventriculoperitoneal shunts, the intracranial pressure increased more than 15 mmHg above baseline during a CO2 pneumoperitoneum of 10 mmHg pressure only (170). In another study of 18 patients with ventriculoperitoneal shunts undergoing 19 laparo-scopic procedures, however, bradycardia and hypertension, which would be expected if the intracranial pressure increase is clinically significant, were not observed (171). Cerebral vascular engorgement is the probable mechanism of increased intracranial pressure during laparoscopy, although in patients with ven-triculoperitoneal shunts, obstruction of the catheter may play a role as well. Patients with significant cerebral vascular disease could suffer ischemia because the cerebral circulation responds to the increased intracranial volume and pressure with a decrease in blood flow...

Chronic Obstructive Pulmonary Disease

Symptoms of late-stage disease include wheezing, chronic sputum production, cough, frequent respiratory infections, dyspnea with exertion progressing to dyspnea at rest, fatigue, pain, hypoxia, and weight loss. Pulmonary hypertension frequently occurs and can lead to cor pulmonale or right-sided heart failure (see Chap.

Capacitance And Resistance Vessels

During changes in posture, alterations in venous capacitance provide the mechanism for maintaining and limiting changes in cardiac output. Impairment of venoconstriction by disease or drugs, e.g. antihypertensive agents, leads to a reduction in cardiac output, and hypotension on standing (postural hypotension).

The Burden Of The Disease

The diagnostic criteria for diabetes recommended by the ADA are presented in Table 2-1. In the absence of unequivocal hyperglycemia, one of these criteria must be confirmed on a subsequent day to establish the diagnosis. Although the plasma level of hemoglobin A1c (HbA1c) reflects mean plasma glucose concentrations over the preceding 2 to 3 months, the use of this parameter for the diagnosis of diabetes is currently not recommended.7 Before the development of diabetes, subjects pass through a stage of impaired glucose metabolism characterized by impaired fasting glucose (IFG) levels or impaired glucose tolerance (IGT) (see Table 2-1). These two metabolic disturbances predispose to diabetes and CVD and were recently grouped in the term prediabetes. A cluster of lipid and non-lipid risk factors of metabolic origin mediated by insulin resistance, such as pathologic glucose metabolism, obesity, hypertension, and dyslipidemia, was designated the metabolic

Endothelial Dysfunction

Diabetes vascular disease is characterized by endothelial dysfunction, a biologic abnormality that has been related to hyperglycemia, increased free fatty acid production, decreased bioavailability of endothelium-derived NO, formation of advanced glycation end products (AGE), altered lipoproteins, hypertension, and, as previously mentioned, insulin resistance.11 A decreased bioavailability of endothelium-derived NO, with subsequent impaired endo-thelium-dependent vasodilation, has been observed in diabetic individuals even before the development of detectable atherosclerosis. NO is a potent vasodilator and a key compound of the endothelium-medi-ated control mechanisms of vascular relaxation. In addition, it inhibits platelet activation, limits inflammation by reducing leukocyte adhesion to endothe-lium and migration into the vessel wall, and reduces vascular smooth muscle cell proliferation and migration. As a consequence, an intact NO metabolism in the vessel wall has a protective...

Upon completion of the chapter the reader will be able to

Recognize the underlying causes and contributing factors in the development of hypertension. 4. Recommend appropriate lifestyle modifications and pharmacotherapy for patients with hypertension. 6. Construct an appropriate monitoring plan to assess hypertension treatment. KEY CONCEPTS Hypertension is widely prevalent and accounts for significant morbidity and mortality, as well as billions of dollars in direct and indirect costs. The cause of hypertension is unknown in the majority of cases (primary hypertension), but for patients with secondary hypertension, specific causes can be identified. Patients failing to achieve goal BP despite maximum doses of three antihyper-tensives including a diuretic should be carefully screened for resistant hypertension. The pathophysiology of primary hypertension is heterogeneous, but ultimately exerts its effects through the two primary determinants of BP cardiac output (CO) and peripheral resistance (PR). Appropriate technique in measuring BP is a...

Assessment of baroreceptor responses

Forced expiration against the closed glottis, results in increased intrathoracic pressure, increased central venous pressure and decreased venous return to the heart. The baroreceptors sense the decrease in cardiac output and arterial pressure. In the normal individual, the result is peripheral vasoconstriction and a reflex increase in heart rate to maintain the arterial pressure. On release of the raised intrathoracic pressure, venous return to the heart increases. There is transient hypertension and bradycardia until the peripheral vasoconstriction is reversed. The heart rate response is easier to detect and may be measured at the bedside.

Peripheral Resistance

Elevated peripheral arterial resistance is the hemodynamic hallmark of primary hypertension. The increase in PR typically observed may be due to a reduction in the arterial lumen size as a result of vascular remodeling. This remodeling, or change in vascular tone, may be modulated by various endothelium-derived vasoactive substances, growth factors, and cytokines. This increase in arterial stiffness or reduced compliance results in the observed increase in systolic BP.9

Other Contributing Processes and Factors

Many other processes are proposed to contribute to the development of hypertension, including obesity, physical inactivity, insulin resistance, potassium and magnesium depletion, chronic moderate alcohol consumption, and transient effects of cigarette smoking and caffeine intake.9 The assessment of global cardiovascular risk in all hypertensive patients should be part of the management plan while also pursuing target BPs through nonpharmacologic and pharmacologic means. Regardless of the initiat ing process or processes leading to the development of hypertension, the ultimate goal is to reduce the risk of cardiovascular events and minimize target organ damage. This clearly requires the early identification of risk factors and treatment of patients with hypertension.

Clinical Presentation And Coexisting Risk Factors

Appropriate technique in measuring BP is a vital component to the diagnosis and continued management of hypertension in the outpatient setting. Accurate measurement of a patient's BP identifies and controls for factors that may influence the variability in the measure. Failure to consider how each of these factors may influence BP measurement results in significant variation in measurements, leading to misclas-sification or inaccurate assessments of risk. Factors including body position, cuff size, device selection, auscultatory technique, and dietary intake prior to the clinic visit may contribute to such inaccuracies. Clinicians should instruct patients to avoid exercise, alcohol, caffeine, or nicotine consumption 30 minutes before BP measurement. Patients should be sitting comfortably with their back supported and arm free of con-strictive clothing with legs uncrossed and feet flat on the floor for a minimum of 5 minutes before the first reading. Finally, the measurement of clinic...

Heart Failure and Diabetic Cardiomyopathy

Of diabetic patients after exclusion of left ventricular hypertrophy or ischemia.32 In the 1970s, the observation that diabetic patients may suffer from congestive heart failure in the absence of hypertension, CAD, or other evident source of cardiac disease led to the concept of diabetic cardiomyopathy, also called diabetic heart disease. Although the exact mechanisms underlying the condition are unknown, the accumulation of extracellular matrix proteins, and in particular of collagen, appears to be a key biologic dysfunction (Fig. 2-4).33 The deposition may be the result of excess production, reduced degradation, and or chemical modification of extracellular matrix proteins. These processes are believed to be induced directly or indirectly by hyperglycemia. Fibrosis may be the result of both increased activity of angiotensin II receptors and increased levels of angiotensin II.

Treatment Desired Outcomes

Hypertension management by nonpharmacologic and pharmacologic therapies has proven useful in reducing the risk of heart attack, heart failure, stroke, and kidney disease morbidity and mortality. For every 20 mm Hg systolic or 10 mm Hg diastolic increase in BP, there is a doubling of mortality for both ischemic heart disease and stroke.21 The goal of BP management is to reduce the risk of CVD and target organ damage. Targeting a specific BP is actually a surrogate goal that has been associated with reductions in CVD and target organ damage.

Nonpharmacologic Treatment Lifestyle Modifications

Therapeutic lifestyle modifications consisting of nonpharmacologic approaches to BP reduction should be an active part of all treatment plans for patients with hypertension. The most widely studied interventions demonstrating effectiveness include Implementation of these lifestyle modifications successfully lowers BP (Table 5 3), often with results similar to those of therapy with a single antihypertensive agent. Combinations of two or more lifestyle modifications can have even greater effects with BP lowering. BP lowering in overweight patients may be seen by a weight loss of as few as 4.5 kg (10 lb). The Dietary Approaches to Stop Hypertension (DASH) trial demonstrated that a diet high in fruits, vegetables, and low-fat dairy BP. Alcohol also attenuates the effects of antihypertensive therapy, which is mostly reversible within 1 to 2 weeks with moderation of intake.

Aldosterone Antagonists

Aldosterone antagonists such as spironolactone, and eplerenone (Fig. 5-3) modulate vascular tone through a variety of mechanisms besides diuresis. Their potassium-sparing effects mediated through aldosterone antagonism, complement the potassium-wasting effects of more potent diuretics such as thiazide or loop diuretics. Patients with resistant hypertension (with or without primary aldosteronism) experience significant BP reductions with the addition of low-dose spironolactone (12.5-50 mg day) to diuretics, ACE inhibitors, and ARBs.68 Although functional in this circumstance, it is important to recognize their potential to enhance the risk for hyperkalemia when used in conjunction with ACE inhibitors, ARBs, and now potentially DRIs. This is particularly relevant for individuals with comorbidities associated with reduced renal function or those receiving either potassium supplements or NSAIDs. The most commonly used potassium-sparing diuretic is spironolactone however, eplerenone has...

Cardiovascular Diagnostic Modalities In Diabetes Patients

Symptoms nor evidence of cardiac or peripheral vascular disease, the ADA guidelines recommend testing for those who have two or more CV risk factors (i.e., dyslipidemia, hypertension, active smoking, family history of premature CAD, or albuminuria). Although the short-term prognosis (i.e., up to 2 years) in diabetic patients after a negative stress imaging test is excellent, multiple studies have found that those patients may suffer high late-event rates. This phe-

Future Of The Preparticipation Examination

Hypertension (high blood pressure) Qualified yes Explanation Those with significant essential (unexplained) hypertension should avoid weight and power lifting, body building, and strength training. Those with secondary hypertension (hypertension caused by a previously identified disease) or severe essential hypertension need evaluation. The National High Blood Pressure Education Working group defined significant and severe hypertension. Explanation Fever can increase cardiopulmonary effort, reduce maximum exercise capacity, make heat illness more likely, and increase orthostatic hypertension during exercise. Fever may rarely accompany myocarditis or other infections that may make exercise dangerous.

Revascularization In Diabetic Patients With Stable Coronary Disease

In addition to increased periprocedural morbidity and mortality, as well as long-term mortality, diabetes is associated with an increased rate of repeat revascularization after CABG. A prospective analysis on 26,927 patients who were contacted every 5 years up to 25 years after CABG at a single institution in the United States identified diabetes as an independent predictor of subsequent coronary revasculariza-tion (Fig. 2-6).60 As part of the metabolic syndrome, diabetes is frequently associated with obesity, hypertension, and hypertriglyceridemia. The impact of these four factors (the deadly quartet) on 8-year mortality after CABG was assessed in a single-center database that included 6428 patients.61 Compared with individuals who had no risk factors, the HR for mortality increased from 1.6 among those with one risk factor to 3.9 for those with four risk factors. The yearly mortality rate ranged from 1 in patients with

Angiotensin Receptor Blockers

ARBs are another key class of agents whose role in managing patients with hypertension has been further defined by recently completed studies. ARBs are inhibitors of the angiotensin-1 (ATI) receptors (Fig. 5-3). ATI receptor stimulation evokes a pressor response via a host of accompanying effects on catecholamines, aldosterone, and thirst. Consequently, inhibition of ATI receptors directly prevents this pressor response and results in up-regulation of the RAAS. Up-regulation of the RAAS results in elevated levels of angiotensin II, which have the added effect of stimulating the angiotensin-2 (AT2) receptors. AT2-receptor stimulation is generally associated with antihypertensive activity however, long-term effects of AT2-receptor stimulation that involve cellular growth and repair are relatively unknown. What is clear is that ARBs differ from ACE inhibitors in that the former causes up-regulation of the RAAS while the latter blocks the breakdown of bradykinin. The therapeutic relevance...

Regulation of blood flow

Autoregulation of cerebral blood flow is the remarkable capacity of the vascular system to adjust its resistance in such a way that blood flow is kept constant over a wide range of cerebral perfusion pressures (80-150 mmHg). The range of autoregulation is shifted to the right, i.e. to higher values, in patients with hypertension and to the left during hypercarbia. The myogenic theory of autoregulation suggests that changes in vessel diameter are caused by the direct effect of blood pressure variations on the myogenic tone of vessel walls. Other influences are mediated by metabolic and neurogenic factors but these may be secondary and are not of great significance.

Patient Care and Monitoring

Conduct a medication history (prescription, over-the-counter, and dietary supplements) to determine conditions or causes of hypertension. Does the patient take any medications, supplements, herbal products, or foods that may elevate SBP or DBP Does the patient have drug allergies 7. If patient is not at goal BP, assess efficacy, safety, and compliance of the antihypertensive regimen to determine if a dose increase or additional antihypertensive agent (step 8) is needed to achieve goal BP. 9. Open a dialogue to address patient concerns about hypertension and management of the condition.

Physiology Of Blood Flow And Blood Pressure

While the control of the cardiac output is usually determined by local tissue flow under physiological states, the control ofthe arterial pressure is independent ofthese and is regulated through a complex system, which involves nervous reflexes and neurohumoral mechanisms for short-term needs (such as flight, fright, and fight type reactions or in situations like those following acute loss of blood volume) and neuroendocrine, renin-angiotensin-aldosterone system, and renal mechanisms for long-term adaptation. These control systems in the normal as well as their alterations in hypertension and in heart failure are well discussed in standard texts for physiology and medicine. In this chapter our focus will be mainly on measurement of blood pressure by the sphyg-momanometer and its use in special clinical situations.

General Signs and Symptoms

Sure to the abdomen can elicit a sustained elevation of JVP, this is defined as hepatojugular reflux (HJR). A positive finding of HJR indicates hepatic congestion and results from displacement of volume from the abdomen into the jugular vein because the right atrium is unable to accept this additional blood. Hepatic congestion can cause abnormalities in liver function, which can be evident in liver function tests and or clotting times. Development of hepatomegaly occurs infrequently and is caused by long-term systemic venous congestion. Intestinal or abdominal congestion can also be present, but usually doesn't lead to characteristic signs unless overt ascites is evident. In advanced RVF, evidence of pulmonary hypertension may be present (e.g., right ventricular heave).

Control and Treatment of Contributing Disorders

All causes of HF must be investigated to determine the etiology of cardiac dysfunction in a given patient. Because the most common etiology of HF in the United States is ischemic heart disease, assessment for cardiac ischemia, which may include stress testing, echocardiography, and or coronary angiography is warranted in the majority of patients with a history suggestive of underlying CAD. Revascularization of those with significant CAD may help restore some cardiac function in patients with reversible ischemic defects. Aggressive control of hypertension, diabetes, and obesity is also essential because each of these conditions can cause further cardiac damage. Surgical repair of valvular disease or congenital malformations may be warranted if detected. Because clinical HF is partly dependent on metabolic processes, correction of imbalances such as thyroid disease, anemia, and nutritional deficiencies is required. Other more rare causes such as autoimmune disorders or acquired...

Pharmacologic Treatment

Two types of diuretics are used for volume management in HF thiazides and loop diuretics. Thiazide diuretics such as hydrochlorothiazide, chlorthalidone, and metolazone block sodium and chloride reabsorption in the distal convoluted tubule. Thiazides are weaker than loop diuretics in terms of effecting an increase in urine output and therefore are not utilized frequently as monotherapy in HF. They are optimally suited for patients with hypertension who have mild congestion. Additionally, the action of thiazides is limited in patients with renal insufficiency (creatinine clear

Multifactorial Intervention

The Steno-2 study compared the efficacy of a targeted, intensified, multifactorial intervention with that of conventional treatment on modifiable risk factors for CV disease in 160 patients with diabetes and microalbuminuria.140 The primary end point was a composite of CV death, nonfatal MI, stroke, revas-cularization, and amputation. Intensive treatment was characterized by a stepwise implementation of behavior modification and pharmacologic therapy that targeted hyperglycemia, hypertension, dyslipid-emia, and microalbuminuria, along with secondary CV prevention with aspirin. Conventional treatment was in accordance with national guidelines. After a mean follow-up of 8 years, patients receiving intensive therapy had a significantly lower risk of CVD (HR 0.47), nephropathy (HR 0.39), retinopathy (HR 0.42), and autonomic neuropathy (HR 0.37). The authors concluded that a target-driven, long-term, intensified intervention aimed at multiple risk

HF With Preserved LVEF

It is now recognized that a significant number of patients exhibiting HF symptoms have normal systolic function or preserved LVEF (40-60 ). It is believed that the primary defect in these patients is impaired ventricular relaxation and filling, commonly referred to as diastolic dysfunction or diastolic HF. HF with preserved EF is more prevalent in older women and is closely associated with hypertension or diabetes, and to a lesser extent, CAD and atrial fibrillation.44 Morbidity in HF patients with preserved EF is comparable to those with depressed EF, as both are characterized by frequent, repeated hospitalizations.44 However, HT with preserved TT is associated with better survival. The diagnosis is based on findings of typical signs and symptoms of HT, in conjunction with echocardiographic evidence of normal LV systolic function and no valvular disease.

Patient Encounter Part 3

In the absence of more landmark clinical studies, the current treatment approach for diastolic dysfunction or preserved LVEF is (a) correction or control of underlying etiologies (including optimal treatment of hypertension and CAD and maintenance of normal sinus rhythm) (b) reduction of cardiac filling pressures at rest and during exertion and (c) increased diastolic filling time. Diuretics are frequently used to control congestion. Recent studies failed to show significant reductions in mortality or hospitalizations with use of ARBs. P-Blockers and calcium channel blockers can theoretically improve ventricular relaxation through negative inotropic and chronotropic effects. Unlike in systolic HF, nondihydropyridine calcium channel blockers (diltiazem and verapamil) may be especially useful in improving diastolic function by limiting the availability of calcium that mediates contractility. A recent study did not find favorable effects with digoxin in patients with mild to moderate...

AAdrenergic receptor antagonists

A-Adrenergic antagonists (a-blockers) selectively inhibit the action of catecholamines at a-adrenergic receptors. They are used mainly as vasodilators for the second-line treatment of hypertension or as urinary tract smooth muscle relaxants in patients with benign prostatic hyperplasia. They also have an important role in the preoperative management of phaeochromocytoma (see Ch. 55).

Points To Remember When Measuring Blood Pressure

First determine roughly the systolic pressure by palpation of the radial artery pulse as the cuff is gradually being deflated so that an auscultatory gap (during which Korotkoff sounds may disappear altogether and reappear again when the cuff is being deflated further), if present, will not be missed. This sometime occurs in some hypertensive patients (13). The auscultatory gap may also be a result of venous congestion and decreased velocity of blood flow in the extremity where the blood pressure is being measured (6). The systolic pressure estimated by the palpation of the distal radial artery (while compressing the proximal brachial artery) is usually 10 mmHg lower than the systolic pressure as assessed by the auscultatory method.

Factors That Affect Blood Pressure Readings

Excessive use of liquorice can lead to sustained hypertension. 10. Significant drop in blood pressure may be noted on postural change from a supine to an erect position (postural hypotension) in patients with hypovolemia, following use of certain antihypertensive drugs, and in patients with diabetes with autonomic dysfunction. This is more common in type 1 diabetics.

Cerebellar Infarct and Vertebral Artery Neck Occlusion

A 55-year-old Caucasian man suddenly became dizzy while shoveling snow and could not walk. His wife helped him inside. In the ambulance he vomited and felt discomfort in the back of his left head, neck, and shoulder. He had had hypertension for 10 years, and 5 years ago he had coronary artery bypass surgery. He took aspirin, a statin, and an angiotensin converting enzyme inhibitor. Three days before, he had had a very brief attack of dizziness and blurred vision, and had veered to the left. He had not reported this episode to his doctor.

Interpretation Of Blood Pressure Measurements

Several important points need to be kept in mind in the interpretation ofblood pressure recordings.Diagnosis of hypertension requires demonstration of sustained elevations of blood pressures under normal resting conditions. The normal upper level of blood pressure for adults regardless of age is 140 80. In fact, some newer studies suggest that mortality and cardiac events are less frequent in those with blood pressures of less than 125 75. Present recommendations suggest the blood pressure in diabetics be controlled to 130 80, and if renal disease or microalbuminuria is also present the pressure should be 120 70 or lower. It appears that lower is better as long as the patient does not suffer any symptoms or adverse effects of hypotension and remains asymptomatic. Documentation of sustained elevations of blood pressures therefore requires more than one observation. Sometimes self-recorded pressures at home and or recordings using an ambulatory monitoring system may have to be resorted...

Second and thirdgeneration calcium antagonists

Nimodipine is selective for cerebral vasculature and is used to prevent vasospasm after subarachnoid haemorrhage. Nicardipine causes less reduction in myocardial contractility than other calcium antagonists. Felodipine acts predominantly on peripheral vascular smooth muscle and has negligible effects on myocardial contractility, although it does produce coronary vasodilatation. It also has a mild diuretic and natriuretic effect. It is indicated for the treatment of hypertension, but has been used in patients with impaired LV function. Felodipine is formulated in a hydrophilic gel which limits the release of drug and prolongs its absorption. Hence bioavailability is low and plasma concentrations are stable after 12-24 h. Mibefradil is a tetralol derivative which selectively blocks T-type calcium channels and was recently introduced for the treatment of hypertension and angina. It causes coronary artery vasodilatation without suppressing myocardial contractility, and heart rate is...

Clinical Examples Of The Anatomic Paradigm In Practice

Dard therapy that render trials outdated. The results of a randomized trial do not necessarily apply to populations that were systematically excluded from that trial. Because most trials, especially procedural trials, exclude patients with complex and high-risk conditions, their results provide the most guidance for the simplest decisions. Almost all CABG trials have systematically excluded patients within 7 to 30 days of an acute MI, patients with LVEF less than .35, hemodynamically unstable patients, patients with anatomy deemed unfavorable for CABG (no anatomic contraindication is harder to define than diffuse disease), patients older than 70 years of age, patients with one or more prior heart surgeries, and patients with severe comorbidities, including but not limited to chronic obstructive pulmonary disease, pulmonary hypertension, prior stroke, cancer, severe liver disease, and severe renal failure.

Key Concepts in Evidence Based Prevention

Cardiovascular disease prevention requires treatment of modifiable risk factors, including hypertension, hyperlipidemia, and smoking, to prevent cardiovascular events and cardiovascular-related deaths. Short, simple depression screening instruments accurately identify patients who can benefit from early identification and treatment. Using local health departments as a resource, a family physician's knowledge of his or her patient population is the best guide to developing a risk-based screening strategy for sexually transmitted infections (e.g., HIV, chlamydia, gonorrhea). Diabetes screening should be offered to adults with hypertension. All women age 65 years or older and women age 60 or older with risk factors should be routinely screened for osteoporosis. Intensive behavioral counseling about consuming a healthy diet should be offered to all adults with hyperlipidemia and other known risk factors for cardiovascular and diet-related chronic diseases. Prevention plays a critical role...

Clinical applications of ACE inhibition

ACE inhibitors are established in the treatment of hypertension they decrease morbidity and mortality in congestive cardiac failure, and improve left ventricular dysfunction after myocardial infarction. They delay the progression of diabetic nephropathy and have a protective effect in non-diabetic chronic renal failure, although they are associated with proteinuria in approximately 1 of patients. ACE inhibitors improve vascular endothelial function by their effects on A-II and bradykinin the clinical importance of this in patients with vascular disease is unknown. ACE inhibitors are generally tolerated well, with no rebound hypertension after stopping therapy and few metabolic effects. Symptomatic first-dose hypotension may occur, particularly in hypo-volaemic or sodium-depleted patients with high plasma renin concentrations. Symptomatic hypotension was more common with the higher doses originally used. ACE inhibitors have a synergistic effect with diuretics (which increase the...

End Stage Renal Disease

Cardiovascular mortality in the general population (GP, data from the National Center for Health Statistics) compared with patients with end-stage renal disease treated by dialysis (data from United States Renal Data System, 1994-1996). (From Sarnak MJ, Levey AS, Schoolwerth AC, et al Kidney disease as a risk factor for development of cardiovascular disease A statement from the American Heart Association Councils on Kidney in Cardiovascular Disease, High Blood Pressure Research, Clinical Cardiology, and Epidemiology and Prevention. Circulation 2003 108 2155.)

Assessment ofArterial Occlusion

Most coarctations usually occur after the take-off of the left subclavian, and the upper extremity pressures will be equal. Since coarctation also causes hypertension, in younger patients with hypertension, as detected in the arm blood pressures, lower blood pressures in the legs must suggest a diagnosis of coarctation. The amount of decrease in the blood pressures in the lower extremities will depend on the severity of the coarctation. When the coarctation is severe, the femoral pulses may not only be delayed but also poorly felt or not palpable. Coarctation causes hypertension as a direct result of the obstruction limiting the size of capacitance of the aorta as well as directly raising the resistance. In addition, the decreased blood pressure distal to the coarctation will lead to stimulation of the juxtaglomerular cells to produce more renin The latter will increase the angiotensin II, which is a potent vasoconstrictor and will result in hypertension.

Drugs Used For 1he Treatment Of Congestive Cardiac Failure

Congestive cardiac failure may be caused by impaired systolic function (when ejection fraction is low), impaired diastolic function (occurring mainly in the elderly ejection fraction is normal, and there may be hypertension), or by a mixture of the two. The decrease in cardiac output causes sympathetic nervous stimulation and increased plasma and cardiac norepinephrine concentrations, increasing cardiac output, systemic vascular resistance and afterload.

Characteristics of Stroke

Apart from age, the most important risk factor for CVD is arterial hypertension. Control of severe and moderate, and even mild, hypertension has been shown to reduce stroke occurrence and stroke fatality. Cardiac impairment ranks third, following age and hypertensive disease. At any level of blood pressure, people with cardiac disease, occult or overt, have more than twice the risk of stroke. Other risk factors are cigarette smoking, increased total serum cholesterol, blood hemoglobin concentration, obesity, and use of oral contraceptives.

Burden of Disease

Hypertension (HTN) is the most common cardiovascular disease and the most common reason patients visit family physicians (AAFP, 2002 AHA, 2005). Approximately 30 of adult Americans have hypertension 7 of adults with HTN have never been told by their physician that they have high blood pressure (BP). Age is an important risk factor for hypertension 7 of adults 18 to 39 years old have hypertension, versus 67 of adults age 60 and older (Ostchega et al., 2008). The risk of death from coronary artery disease and stroke (cerebrovascular accident, CVA) is doubled with every 20-mm Hg systolic or 10-mm Hg diastolic increase in BP (Table 6-4). Elevated BP is also associated with heart failure and renal disease (JNC-7, 2004). Treatment and control of hypertension are less than ideal 68 of hypertensive adults are treated with BP medications, and of those treated, 64 had their BP lowered to recommended levels (Ostchega et al., 2008).

Accuracy of Screening Tests

Office-based BP measurements are typically done with a sphygmomanometer. The accuracy depends on the examiner, patient factors, and the instrument used. Because of the resulting variability, two BP measurements at separate visits are necessary for diagnosis. Properly performed measurements are highly correlated with arterial BP and predict cardiac risk. Ambulatory monitoring may be more accurate and a better predictor of cardiac risk than office BP measurement, but it is subject to the same errors. A significant advantage of ambulatory monitoring is that it may identify patients with white coat hypertension (Sheridan et al., 2003).

Additional Neurological Findings

The general physical examination may reveal reversible memory disturbances, the most common causes of which are intracranial masses, normal pressure hydrocephalus, thyroid dysfunction, and vitamin B12 deficiency. Examination of the patient's general appearance, vital signs, skin and mucous membranes, head, neck, chest, and abdomen should reveal clinical signs that will aid in the differential diagnoses of dementia and amnesic syndromes. Fever, tachycardia, hypertension or hypotension, sweating, hypothermia, and impaired level of consciousness should suggest a systemic disease, anticholinergic intoxication, or withdrawal from ethanol or sedative drugs rather than an isolated memory disorder. Jaundice suggests hepatic disease glossitis, intestinal problems, and yellowish skin suggest a vitamin B12 deficiency hot, dry skin is often characteristic of anticholinergic drug intoxication. Hypothermia, hypotension, bradycardia, coarse dry skin, brittle hair, and subcutaneous edema are...

Effectiveness of Early Detection and Intervention

No studies have examined the direct effect of screening on clinical outcomes however, treating a patient for hypertension detected through screening appears to provide morbidity and mortality benefits. The benefits of screening and treatment depend on the degree of BP elevation and the presence of other cardiovascular risk factors, such as age, gender, lipid disorders, and diabetes. Potential harms from screening include labeling and exposure to the side effects of antihy-pertensive treatment.

Blood Pressure in Assessment of Relative Intensity of the First and Second Heart Sounds

The integrity of the left ventricular function has a significant bearing on the intensity of the Ml component of the S1 (see Chapter 6). When S1 and S2 are not loud enough to be palpable, the assessment of their intensity must take into account the measured blood pressure of the patient. Extracardiac attenuating factors can lead to attenuations of the heart sounds. Because the degree of attenuation in any given patient will be expected to be similar on both S1 and S2, the intensity of S1 can be assessed only when compared to the intensity of the S2. The intensity or the loudness of the A2 component of the S2 is dependent to a large extent on the peripheral resistance, which is reflected in the diastolic blood pressure. A normal blood pressure would be expected to be associated with a normal intensity of A2, a high blood pressure would be expected to cause a loud A2, and finally a low blood pressure would be associated with a soft A2. The A2 intensity can be graded according to the...

Occupational Diseases

The growing attention to the hazards of the industrial workplace has alerted workers even in clean worksites to occupational disease. Physical dangers are posed to office workers by video display terminals, poorly designed furniture, noise, and vibrations. Stress at the workplace is now seen as important in the creation of the modern epidemics of high blood pressure, heart disease, and stroke. The very definition of disease has been altered by a rising popular and professional consciousness of the importance of occupation as a source of illness.

The Psychosomatic Patient

There are many ways of dealing with psychosomatic patients. First, identify the disorder Do not miss the possible diagnosis of an affective or anxiety disorder. Treatment of somatization is directed toward teaching the patient to cope with the psychological problems. Be aware that somatization operates unconsciously the patient really is suffering. Above all, the patient should never be told that his or her problem is ''in your head.'' Anxiety, fear, and depression are the main psychological problems associated with psychosomatic illness. The list of associated common symptoms and illnesses is long and includes chest pain, headaches, peptic ulcer disease, ulcerative colitis, irritable bowel syndrome, nausea, vomiting, anorexia nervosa, urticaria, tachycardia, hypertension, asthma, migraine, muscle tension syndromes, obesity, rashes, and dizziness. Answers to an open-ended question such as ''What's been happening in your life '' often provide insight into the problems.

Types of cardiovascular disease

Disease of the blood vessels supplying the heart muscle. Major risk factors High blood pressure, high blood cholesterol, tobacco use, unhealthy diet, physical inactivity, diabetes, advancing age, inherited (genetic) disposition. Other risk factors Poverty, low educational status, poor mental health (depression), inflammation and blood clotting disorders. Inflammation, drugs, high blood pressure, unhealthy diet, trauma, toxins and alcohol. brain. This may result from either blockage (ischaemic stroke) or rupture of a blood vessel (haemorrhagic stroke). Risk factors High blood pressure, atrial fibrillation (a heart rhythm disorder), high blood cholesterol, tobacco use, unhealthy diet, physical inactivity, diabetes, and advancing age. Dilatation and rupture of the aorta. Risk factors Advancing age, longstanding high blood pressure, Marfan syndrome, congenital heart disorders, syphilis, and other infectious and inflammatory disorders.

Blunt Abdominal Trauma

Abdominal trauma, but less than 1 deliver before 34 weeks. Tocolytics should be used guardedly, lest they mask the sign of abruption. Contractions following blunt abdominal trauma abate without treatment in 90 of cases. All tocolytics have side-effects which the obstetrician should be familiar with beta mimetics induce tachycardia and may mask the early signs of abruption non-steroidal anti-inflammatory agents affect platelet and renal function and calcium channel blockers cause hypertension. The fetal heart rate and the uterine contractions should be continuously monitored34.

Other Noninterventional Strategies

A variety of other medical and supportive measures have been recommended to reduce the likelihood of ischemic cardiac complications after noncardiac surgery, although randomized controlled trial data evaluating these strategies are typically absent. Among individuals with known or suspected coronary disease, aspirin should be reinitiated as soon as possible after surgery. Perioperative hypertension should be controlled, and patients with left ventricular dysfunction or history of congestive heart failure should receive angiotensin-converting enzyme inhibitor therapy if possible.30 Postoperative pain should be controlled aggressively to keep catecholamine

Arachidonic acid metabolites

Continuous infusion of PGI2 has been used in pulmonary hypertension, but systemic hypotension may be a problem. Non-steroidal anti-inflammatory drugs such as indomethacin or aspirin inhibit production of PGI2 these agents may accentuate hypoxic pulmonary vasoconstriction.

Percutaneous Coronary Intervention

More than 1 million PCIs are performed annually in the United States, and an estimated 33 of patients undergoing PCI are women.1,2 Compared with men, women undergoing PCI are 5 years older and have higher prevalences of hypertension, diabetes, and other comorbidities.3-5 They are less likely to have had a history of MI, PCI, or coronary artery bypass grafting (CABG). At the time of PCI, they have less multivessel disease and are more likely to present with unstable angina.3-5 Unlike men, they require more urgent procedures and are more likely to have rotational atherectomy. Paradoxically, given their higher risk profile, women tend to have similar lesion types, less multivessel disease, and more preserved left ventricular (LV) function than men.3-5 However,

Prevalence and risk factors

Lacunar infarcts are formed on a risk-factor profile that comprises age, gender, hypertension, diabetes, smoking, previous TIA and possibly ischemic heart disease. In particular, hypertension was initially thought to be a prerequisite for the development of small-vessel occlusion. However, later studies have demonstrated that the vascular risk-factor profile is not specific for lacunar infarction, but is largely similar to other stroke types 30 . Lacunar infarcts are also part of the clinical spectrum of cerebral autosomal dominant arteriopathy with subcortical infarcts and leuken-cephalopathy (CADASIL), a genetic disease affecting the small arteries of the brain (see Chapter 9).

Acute Coronary Syndromes

Women who present with ACS are older and have higher incidences of diabetes and hypertension compared to men. They also have less severe CAD, with greater absence of critical obstructions and more preserved LV function. In ACS, women were more likely to have elevated C-reactive protein (CRP) and brain natriuretic peptide (BNP), whereas men were more likely to have elevated creatine kinase-MB (CK-MB) and troponin.33

STSegment Elevation Myocardial Infarction

There has been much controversy surrounding mortality rate differences between women and men after STEMI (Table 8-4). There appears to be a higher in-hospital mortality rate in women undergoing PCI for STEMI compared to men. A large study using Nationwide Inpatient Sample of 11,717 women and 24,028 men found 5.2 in-hospital mortality in women and 2.7 in men. Even after adjusting for age, hypertension, institutional volume, and pulmonary disease, women had a higher mortality rate (OR 1.47 95 CI 1.23 to 1.75).50 Similarly, the New York State Department of Health database found that women had a significantly higher adjusted in-hospi-tal mortality rate (OR 2.69 95 CI 1.4 to 5.2).13 However, at 30 days and at 1 year, there was no apparent difference in mortality rate between the two groups.

Coronary Artery Disease

Various ethnic minority groups are experiencing increasing rates of ischemic heart disease. Rates for CAD are increasing in Asian Americans, Hispanic Americans, and Native Americans.1 Despite the increased incidence of CAD in African Americans, the presence of obstructive epicardial CAD on angi-ography is less than whites.81 Paradoxically, there is greater extent of atherosclerosis in African Americans despite less obstructive CAD. The increased prevalence of CAD in African Americans is most likely due to increased rates of hypertension, diabetes, and smoking, and not to inherent differences in patho-physiology of CAD.81 Of note, African Americans tend to have more peripheral arterial disease than their white counterparts (adjusted OR 2.39 95 CI 1.11 to 5.12). This was seen in the National Health and Nutrition Examination Survey in United States.82 It was confirmed by the NHLBI Genetic Epidemiology Network of Arteriopathy (GENOA) study, which

Transdermal patch systems

Transdermal delivery is the term that is confined to a situation in which the drug diffuses through different layers of the skin into systemic circulation to elicit the therapeutic response (Brown et al., 2006). An example would be management of hypertension using a transdermal clonidine patch. In a broader sense transdermal delivery also includes local anesthetic patches in which the drug is intended to diffuse regionally in the skin to elicit the pharmacological action only in the treated area of the skin. Often, delivery of local anesthesia has been classified under topical drug delivery. An overview of cutaneous drug delivery system is shown in Figure 1.2.

Patient Encounter Part 1

A 49-year-old man with a medical history of hypertension presents to the clinic complaining of shortness of breath that began about 3 to 4 years ago. His symptoms have gradually gotten worse since then. He is now unable to walk 100 yards without having to stop and rest. He also has a daily cough that is usually productive of yellowish sputum. He smokes about one and a half packs of cigarettes a day and has done so for the last 30 years. He also drinks on average six to seven beers a day. He does not have any significant occupational exposures to dust, gases, or fumes.

Written History of Mr John

Over the past 6 months, the patient has had increasing chest pain with radiation down his left arm despite atenolol, 50 mg daily, and isosorbide dinitrate, 10 mg qid. The patient's chest pain is produced by exercise, emotion, and sexual intercourse. The patient takes nitroglycerin as needed, with relief within 5 minutes. One-block dyspnea on exertion is also present. This has worsened in the past 6 months, before which he could walk two to three blocks. The patient's risk factors for coronary artery disease include a history of untreated hypertension, a 40-pack-year history of smoking (2 packs per day for 20 years), and a brother with a myocardial infarction at the age of 40 years. The patient's brother is now 45 years of age. The patient denies any history of diabetes or hyperlipidemia. At his physician's and wife's request, he has entered the hospital for elective cardiac catheterization. The patient has a significant denial of his illness and a secondary depression. Although...

Nonpharmacologic Therapy

Long-term administration of oxygen (greater than 15 hours per day) to patients with chronic respiratory failure has been shown to reduce mortality and improve quality of life.1,2 Oxygen therapy should be initiated in stable patients with very severe COPD (GOLD stage IV) who are optimized on drug therapy and meet one of the following criteria (a) A resting PaO2 at or below 55 mm Hg (7.32 kPa) or oxygen saturation (SaO2) at or below 88 or (b) PaO2 between 55 and 60 mm Hg (7.32 and 7.98 kPa) or SaO2 of 89 and evidence of pulmonary hypertension, peripheral edema suggesting congestive heart failure, or polycythemia.1,

Making Clinical Decisions

A typical family physician sees a patient every 15 minutes and addresses three separate problems during the visit (Bea-sley et al., 2004). Busy clinicians operating in such an environment must make snap decisions regarding patient care. Ethnographic studies of actual physician decision making in primary care offices indicate that physicians rely on mind-lines to guide them (Gabbay and le May, 2004). Physicians develop these mindlines as a preconceived, conceptualized, and standardized approach to a particular clinical scenario. For example, for a child with fever and tonsillar exudates, one physician's mindline may be to treat with penicillin, and another physician's mindline may be to obtain a culture and treat if the results are positive for Streptococcus. The foundation of these mindlines is the tacit knowledge physicians acquire during their early training. For example, the best predictor of a clinician's knowledge about hypertension treatment is his or her year of graduation from...

Gastrointestinal System

Hepatobiliary disease occurs due to bile duct obstruction from abnormal bile composition and flow. Hepatomegaly, splenomegaly, and cholecystitis may be present. Hepatic steatosis may also be present due to effects of malnutrition. The progression from cholestasis (impaired bile flow) to portal fibrosis and to focal and multilobar cirrhosis, esophageal varices, and portal hypertension takes several years. Many patients are compensated and asymptomatic but may be susceptible to acute decompensation in the event of extrinsic hepatic insult from viruses, medications, or other factors.7

Other Techniques And Modifications Direct Supragastric Left Sided Adrenalectomy

The gland is dissected along its medial and then inferior aspects, and the main adrenal vein then identified and divided (14). In this series of 23 cases, however, three required conversion owing to intraoperative hemorrhage, and one case of pheochromocytoma was complicated by intraoperative hypertension secondary to gland manipulation prior to venous control.

Risk factors start in childhood and youth

Markers of CVD can be seen in young children. Post-mortems of children who died in accidents have found fatty streaks and fibrous plaques in the coronary arteries. These early lesions of atherosclerosis were most frequently found in children whose risk factors included smoking, elevated plasma lipids, high blood pressure and obesity.

Preoperative Optimization

Patients with hyperaldosteronism should have adequate control of blood pressure and correction of hypokalemia and other electrolyte abnormalities. Alpha-blockers, namely phe-noxybenzamine, and beta-blockers are administered in patients with pheochromocytomas to control reflex tachycardia when needed. The authors initiate administering these drugs three to four weeks prior to surgery and assess their efficiency by monitoring the improvement of symptoms, stabilization of blood pressure, and the presence of mild orthostatic hypotension. Following this concept, the mortality of patients with pheochromocytoma has declined to 1 (31). A different approach to manage hypertension using calcium channel blockers started as late as 24 hours prior to surgery has shown good results (32).

Pheochromocytoma Potential Surgical Risks

Long-standing hypertension can produce end-organ damage resulting in heart failure, catecholamine-induced cardiomyopathy, stroke, and retinal damage. Such patients with pheochromocytoma constitute a high-risk group. Intraoperative manipulation of the tumor may induce excess catecholamine release resulting in life-threatening hypertensive crisis. Although it has been speculated that pneumoperitoneum may induce a hypertensive crisis owing to hypercapnia or positive pressure, available evidence suggests to the contrary (33,34). In the author's experience, severe hypertension was triggered only by direct manipulation of the adrenal gland and not by pneumoperi-toneum. Hence, laparoscopic tissue dissection is kept to a minimum, and a direct transperitoneal approach to the adrenal vein is preferred (Fig. 2) (7). Interestingly, when performing partial adrenalectomy without clamping or dividing the adrenal vein, no major problem was encountered in authors' series (7) owing to effective alpha...

Precordial Movement and Palpation

Precordial movements are influenced by the spatial orientation of the ventricular septum and by the anterior and leftward position of the ascending aorta. The plane of the ventricular septum faces forward, and a vertical interven-tricular sulcus is closely aligned with the left sternal border (see Fig. 6-6B).44'67 Accordingly, an inverted right ventricle occupies an anterior and leftward position with its medial border adjacent to the left sternal edge and its lateral border at the apex (see Fig. 6-2B), an arrangement that accounts for the large topographic area generated by the right ventricular impulse. The impulse of the anteroapical right ventricle is accentuated by left atrioven-tricular valve regurgitation, because systolic expansion of the left atrium causes anterior displacement of the heart (see Fig. 6-6 A). There is no retraction medial to the inter-ventricular sulcus because the sulcus lies too close to the left sternal border (see Fig. 6-6B). The inverted left ventricle...

Is the French Paradox Real

One big surprise is that the French have so few deaths from CAD. This occurs despite the fact that the French consume more fat, and even more saturated or animal fat, than Americans. Furthermore, the French have higher rates than Americans of other risk factors, including elevated blood cholesterol, high blood pressure, and smoking. There are areas in other European countries with rates that are similar to those of the French. The so-called French Paradox (and not the Spanish Paradox or Italian Paradox) lies in the fact that the French consume high levels of animal fat, similar to the intake in Northern Europe, yet have CAD rates similar to those in the Mediterranean countries, where the saturated fat consumption is lower.
