A comparison of methods for assessing total arterial compliance

The terms elastance and compliance are of particular significance in cardiovascular physiology and respiratory physiology. In compliance, an increase in volume occurs in a vessel when the pressure in that vessel is increased. The tendency of the arteries and veins to stretch in response to pressure has a large effect on perfusion and blood pressure. This physically means that blood vessels with a higher compliance deform easier than lower compliance blood vessels under the … Systemic arterial compliance (C) and vascular resistance (R) regulate effective arterial elastance (Ea), an index of artery load. Increases in Ea during exercise are due primarily to reductions of C and maintain optimal ventricular-arterial coupling. See more Table 1shows the subject characteristics of the SC and ET groups. There were no statistical differences in age, height, weight, left ventricular average wall thickness, ejection fraction, or fractional shortening between … See more The salient findings of this study are that the reductions of C from rest to exercise of relatively the same intensities were greater in the ET compared with SC group.
