Question

Underlying mechanism for variant angina is………

• A. Atherosclerosis
• B. Aortic stenosis
• C. Coronary artery spasm
• D. Cardiomyopathy

Hint:

Variant (Prinzmetal’s) angina = episodic chest pain at rest due to coronary artery spasm.

Answer 1

The Correct Option is C

Variant angina, also called Prinzmetal's angina, is caused by coronary artery spasm. Unlike stable angina, it occurs at rest and is due to transient vasoconstriction of coronary arteries, not necessarily related to physical exertion or plaque buildup.
