Marketou ME, et al. – Platelet alpha_2B–adrenergic receptors (α2B–ARs) gene expression levels were assessed in patients with well–controlled essential hypertension versus normal individuals and their relation to increased arterial stiffness was also probed. Findings were suggestive of a link between arterial stiffness and platelet α2B–Rs gene expression. Platelet α2B–R gene expression levels were increased in patients with well–controlled essential hypertension versus normotensives and were correlated with increased pulse wave velocity (PWV) in those patients.
