Intensified large artery and microvascular response to cold adrenergic stimulation in African blacks.

Abstract

Arterial stiffening is more accelerated in blacks than in whites. Whether this is attributed to an enhanced vascular reactivity to environmental stress stimulation remains unknown. We therefore decided to test the hypothesis that cold pressor test (CPT) elicits a greater increase in arterial stiffness and an enhanced sympathetic skin vasoconstriction in African blacks than in whites normotensives.Journal ArticleResearch Support, Non-U.S. Gov'tinfo:eu-repo/semantics/publishe
