Description: symptoms (usually chest discomfort) due to cardiac ischemia, usually caused by coronary artery disease.
Some causes related to cardiovascular disease: usually due to coronary artery disease, although it can sometimes be caused by spasm of the coronary arteries, or by cardiac syndrome x.
Some causes related to other disorders: True angina pectoris, by definition, is always related to cardiac ischemia. Non-ischemic pain should not be referred to by the term "angina." Significance: The presence of angina means that a portion of the heart muscle is not receiving enough blood flow. Angina therefore always has significant medical implications, and requires careful evaluation and therapy.
