WebDec 29, 2024 · Hyperemia occurs because during the period of occlusion, tissue hypoxia and a buildup of vasodilator metabolites dilate arterioles and decrease vascular resistance. Then, when perfusion pressure is restored (i.e., occlusion released), flow becomes elevated because of the reduced vascular resistance. WebPWA during reactive hyperemia is influenced by factors known to affect endothelial function, including cardiovascular risk factors and coronary artery disease. These findings support the concept that analysis of PWA with PAT during reactive hyperemia may be used to study peripheral vascular endothelial function. Publication types
