Abstract
Beta-adrenergic vasodilation plays a key role in the regulation of coronary blood flow, in particular during sympathetic nervous system activation. Beta1-adrenergic receptors are mostly represented in epicardial coronary vessel, while beta2 receptors are located in microvasculature. Coronary atherosclerosis is associated with a significant impairment of beta-adrenergic receptor response. This might contribute to precipitate myocardial ischemia.
