Coronary Vasospastic Disease – Prinzmetal Angina
Prinzmetal’s angina is characterized by a transient reduction in luminal diameter of a coronary artery resulting in spontaneous and often recurrent episodes of angina with electrocardiography (ECG) findings consistent with ST elevation.
While the ischemia induced is usually transient, myocardial infarction and life-threatening arrhythmias can occur in 25% of cases
