Abstract

This study proposes a novel noninvasive arterial stiffness estimation technique based on the oscillometric method and applies it to assess the vascular endothelial function. Change of the arterial stiffness during the enclosed zone flow-mediated dilation test was calculated from the measured blood pressure, the cuff oscillation, and the applied pressure to the cuff. As results, the arterial stiffness change for the four healthy subjects was -42±17% and that for the four patients with high-risk of arteriosclerosis was -2.9±11%. The mean changes had significantly different between the two groups (p<0.01). The result thus indicated proposed method could assess the vascular endothelial function.
