Body height as a determinant of carotid pulse contour in humans

Abstract

Aim: The aim of this study was to assess the effect of body height on arterial wave reflections and the carotid pulse pressure contour in humans.

Methods: In 85 men, the carotid pulse wave and arterial wave reflections were determined from the common carotid artery pulse contour as recorded by applanation tonometry using a Millar micromanometer-tipped probe. The arterial wave reflection was calculated as the ratio of the height of the late systolic peak to the total height of the carotid pulse wave. The reflected wave was timed from the foot of the pressure wave to the foot of the late systolic peak.

Results: Multiple regression analysis showed that body height and aortic pulse wave velocity were the principal determinants of travel time of the reflected wave and of arterial wave reflections (P < 0.0001), short stature being associated with a short travel time and increased reflections (P < 0.0001).

Conclusions: Body height is a determinant of arterial wave reflections and peak systolic blood pressure in humans.
