Clinical Presentation

Any suspicion of PE as a cause of acute shortness of breath requires specific diagnostic evaluation and quick intervention in this potentially life-threatening condition. Acute-onset shortness of breath coupled with pleuritic chest pain, hemoptysis, wedge-shaped pulmonary infarct lesions on chest radiograph, and S1Q3 pattern with tachycardia on ECG can all point specifically to a diagnosis of PE, but most patients have a nonspecific presentation. Collateral circulation from bronchial arteries makes pulmonary infarction relatively uncommon. Massive PE can lead to acute right ventricular failure and cardiovascular collapse. Pao2 greater than 80 mm Hg in room air and a normal A-a O2 gradient make the diagnosis less likely but do not completely exclude PE. All patients with acute-onset shortness of breath with no apparent cause should be evaluated for PE.
