Research Abstract

In this study, we have demonstrated that the exaggerated responses of central arterial pressure and wave reflection markers during dynamic exercise are related to a state of structural and functional impairments of the vasculature in the early stages of hypertension. These results suggest that subclinical atherosclerosis may have a greater influence on vascular reactivity than on basal tone and hence could potentially be identified by an abnormal response of central arterial pressure to exercise even before clinical manifestation of atherosclerosis. In addition, an amplified wave reflection from periphery due to the vascular alterations, such as increased arterial stiffness and endothelial dysfunction, induces greater central aortic pressure and leads to the increase in overall left ventricular afterload. Thus, the central arterial pressure response to exercise may also be useful as an evaluation of hypertension-related risks of cardiovascular complications.
