Prinzmetal angina

Prinzmetal's angina is a rare form of angina (chest pain) caused by the vasospasm of the smooth muscle tissue of the coronary artery, leading to reduced blood flow to the heart muscle. Prinzmetal's angina usually occurs at rest, and symptoms include chest pain, pressure or tightness, shortness of breath, sweating, and nausea or vomiting. Treatment options include nitroglycerine and calcium channel blockers.
