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.
The pattern will disappear when the chest pain resolves. If you do not have heart disease (meaning an X-ray of your heart shows no major blockages in the arteries of your heart) or have only mild heart disease, and this pattern appears during ECG testing, you will probably be diagnosed with a PrinzmetalÃ¢s angina.
