Variant angina is an extremely rare form of angina pectoris that is caused by a spasm in a coronary artery. Angina pectoris, or angina for short, is chest pain or discomfort that occurs when the heart muscle is not getting enough oxygen-rich blood for a short period of time.nlike other types of angina that usually occur in someone with coronary artery disease (also called CAD or just heart disease), variant angina may occur in people with or without this condition.
Related terms: vasospasm, variant angina, Prinzmetal's angina. Sometimes a coronary artery (one of the vessels supplying blood to the heart muscle) goes into spasm. This is also called vasospasm, and doctors are unsure of its cause.The spasm briefly narrows the coronary artery, so your heart does not get enough blood.oronary artery spasm causes a rare type of angina pectoris called variant angina pectoris (or Prinzmetal's angina). Angina pectoris is a squeezing, suffocating, or burning feeling in the chest. Unlike typical angina, variant angina usually happens during times of rest.
