Differences in pulse wave velocity obtained by compared devices resulted primarily from using various methods for measuring traveled distance. It appears reasonable to establish uniform principles for the measurement of traveled distance. Because a large number of prognosis/survival studies used direct distance between carotid and femoral sites of pulse wave recording, this distance should be mostly recommended.

In hypertensive subjects PWV depends on age, systolic BP, and collagen synthesis. Of the three drugs with comparable BP-lowering efficacy only quinapril significantly decreases PWV, plasma aldosterone, and PICP.
