Blockade of platelet alpha2B-adrenergic receptors in patients with coronary artery disease: a novel antiaggregant mechanism

Purpose: Platelets play a vital role in hemostasis and thrombosis. Catecholamines have a profound effect on platelet aggregation and atherothrombosis but the exact mechanism involved is insufficiently understood. In this report, we demonstrate the existence and role of alpha2B–adrenergic receptors (α2B–ARs) in platelets from patients with Coronary Artery Disease (CAD) compared to normal individuals. Methods: Sixteen healthy individuals and 7...
