Variant Angina

Vasospasm of coronary arteries can result in angina. Usually it coexists with atherosclerosis and that too mostly in the cases of unstable angina. Isolated cases of variant angina occur in < 1% of the cases in patients having normal coronary arteries. When variant angina occurs along with presence of transient elevation of ST segment on the ECG it is known as Prinzmetal’s angina.
