Prevention of anginal pain associated with vasospastic angina

Vasospastic angina, historically referred to as Prinzmetal or variant angina, is a cardiovascular disorder characterized by recurrent episodes of chest pain caused by sudden, transient constriction of epicardial coronary arteries

This dynamic reduction in coronary blood flow precipitates acute myocardial ischemia independently of fixed atherosclerotic occlusions, driven pathophysiologically by coronary vascular smooth muscle hypercontractility and endothelial dysfunction Prophylactic management targeting this indication focuses on preventing these episodic spasms, thereby averting anginal pain, myocardial infarction, and serious ventricular arrhythmias

Clinically, affected individuals classically experience spontaneous, nitrate-responsive anginal attacks that occur predominantly at rest, during nighttime or early morning hours, and often accompany transient ischemic electrocardiographic changes such as ST-segment elevation
