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.
Angina is most often caused by narrowing of the coronary arteries because of atherosclerotic heart disease. There may be one or more arteries that are blocked and the amount of pain or other symptom severity is not necessarily related to the number of blood vessels blocked.ome causes for angina are multifactorial. For example, a patient with atherosclerotic heart disease may become acutely ill or injured, where a fever or anemia may compound the inability of narrowed blood vessels to deliver oxygen to heart muscle cells.
