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.
Angina, or angina pectoris, is a medical term for the symptoms caused by the heart not getting enough oxygen from the arteries that supply the heart with blood. When these arteries become narrowed or blocked over time, it is called coronary artery disease (CAD) , and it can cause angina. Most commonly, people describe their symptoms of angina as chest discomfort or pain. Angina can be stable or unstable. When angina becomes unstable, it is commonly associated with a heart attack, which is a medical emergency. Stable angina is not usually an emergency, but it can be painful and frightening.
