Abstract
Beta-blockers are widely prescribed for the treatment of a variety of cardiovascular pathologies. Compared to traditional beta-adrenergic antagonists, beta-blockers of the new generation exhibit ancillary properties such as vasodilation through different mechanisms. This translates into a more favorable hemodynamic profile. The relative affinities of beta-adrenoreceptor antagonists towards the three beta-adrenoreceptor isotypes matter for predicting their functional impact on vasomotor control. This review will focus on the mechanisms underlying beta-blocker-evoked vasorelaxation with a specific emphasis on agonist properties of beta3-adrenergic receptors.

J Am Coll Cardiol. 2009;53:1532–8. This study reports for the first time a ß3-adrenoceptor agonism for Nebivolol, a ß-blocker with vasodilating properties, in human ventricular muscle. These data are important because beta3-adrenoceptors are increased in heart failure, and Nebivolol is recommended to treat this pathology even in elderly patients.

Nebivolol exerts beneficial effects on endothelial function, early endothelial progenitor cells, myocardial neovascularization, and left ventricular dysfunction early after myocardial infarction beyond conventional beta1-blockade. J Am Coll Cardiol. 2011;57:601–11. This study provides novel evidence that nebivolol treatment is associated with beneficial effects on left ventricular dysfunction, cardiomyocyte hypertrophy, and survival early after myocardial infarction, likely independent of β1-adrenoceptos blocking effects. Those effects may be related, at least in part, to activation of β3-adrenoceptors by Nebivolol, which may increase eNOS-dependent NO availability both by preventing NADPH oxidase activation and stimulation of eNO.
