1 Variant angina. 2  Variant angina, also called Prinzmetal's angina, is caused by a spasm in a coronary artery in which the artery temporarily narrows. 3  This narrowing reduces blood flow to your heart, causing chest pain. 4  Variant angina can occur even when you're at rest, and is often severe.ngina is caused by reduced blood flow to your heart muscle. Your blood carries oxygen, which your heart muscle needs to survive. When your heart muscle isn't getting enough oxygen, it causes a condition called ischemia.
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.
