title: Acute myocardial infarction caused by multivessel coronary spasm due to calcium channel blocker withdrawal.
abstract: Calcium channel blockers are a commonly used class of medications for the management of hypertension, angina, and superventricular tachyarrhythmias. Abrupt withdrawal of these agents can precipitate coronary vasospasm, which may result in myocardial infarction. We present the case of a 47-year-old woman who sustained an acute myocardial infarction mediated by multivessel coronary vasospasm secondary to verapamil withdrawal and the associated interventional management.
