Abstract

To establish an evaluation index for vascular endothelial function, we estimated the change of viscoelasticity of the radial artery during flow-mediated dilatation (FMD) using a developed ultrasonic probe that can simultaneously measure the blood pressure and the diameter at the same position. The elasticity after the recirculation from avascularization was larger than that at rest. Moreover, the elasticity increased 100 seconds after the recirculation. The absolute value of the elasticity was different from that before the avascularization. However, the tendency of the change was consistent with our previous study. These results show the possibility to measure the change of viscoelastic characteristics during FMD using a single ultrasonic probe.
