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
