Impaired endothelial repair capacity of early endothelial progenitor cells in prehypertension: relation to endothelial dysfunction.

Prehypertension is a highly frequent condition associated with an increased cardiovascular risk. Endothelial dysfunction is thought to promote the development of hypertension and vascular disease; however, underlying mechanisms remain to be further determined. The present study characterizes for the first time the in vivo endothelial repair capacity of early endothelial progenitor cells (EPCs) in patients with prehypertension/hypertension and examines its relation with endothelial function.
