Endothelial dysfunction and the risk of hypertension: the multi-ethnic study of atherosclerosis.

ABSTRACT: Hypertension is associated with impaired endothelial function in cross-sectional studies. However, few longitudinal data exist on whether endothelial dysfunction precedes the development of hypertension. We examined the cross-sectional and longitudinal relationships between endothelial-dependent brachial artery flow-mediated dilation (FMD) and hypertension prevalence and incidence in 3500 participants from the Multi-Ethnic Study of Atherosclerosis, an ethnically diverse, community-based cohort study. At baseline, the prevalence ratios (95% CI) of hypertension from the highest to the lowest quartile of FMD were 1.00 (referent), 1.26 (1.12 to 1.40), 1.35 (1.21 to 1.52), and 1.68 (1.50 to 1.87; linear trend P<0.001). This association remained (P=0.017) after adjustment for demographics (age,
