Resolution of nebivolol-induced coronary vasospasm by intracoronary nitroglycerin during a coronary angiogram

Abstract

Nebivolol is a novel beta1-selective beta-blocker with vasodilator properties mediated through activation of the l-arginine-nitric oxide pathway. There is no published report of coronary artery spasm associated with nebivolol. We describe a 64-year-old female patient who developed unstable angina secondary to nebivolol-induced vasospastic angina which was also visible during coronary angiography.
