Heart Disease Home > Types of Angina
Variant angina is a rare angina type caused by a spasm in a coronary artery. This spasm causes the walls of the artery to tighten. In turn, this narrows the artery, causing the blood flow to the heart to slow or stop.
Unlike other types of angina that usually occur in someone with coronary artery disease, variant angina may occur in people with or without coronary heart disease.
