Hyperemia-Related Changes in Arterial Stiffness: Comparison between Pulse Wave Velocity and Stiffness Index in the Vascular Reactivity Assessment
Figure 1
Schema of the instrumental approach employed to measure the PWVcr and SI (mechanotransducers), brachial artery diameter (B-mode ultrasound), and blood flow velocity (Doppler signals). Note the carotid and radial pulse pressure (mechanography), the longitudinal view of the brachial artery (B-mode ultrasound), and the brachial blood flow velocity (Doppler signals) before and after the cuffocclusion and deflation were performed. Immediately after the cuff deflation, there is an acute and transient increase in brachial blood flow velocity (RH).
