Coronary Disease Categories.

	Angina Pectoris - The symptom of paroxysmal pain consequent to MYOCARDIAL ISCHEMIA usually of distinctive character, location and radiation. It is thought to be provoked by a transient stressful situation during which the oxygen requirements of the MYOCARDIUM exceed that supplied by the CORONARY CIRCULATION.
	Coronary Aneurysm - Aneurysm of a coronary vessel. A coronary artery aneurysm is rarely congenital; it is usually due to atherosclerosis, inflammatory processes, or a coronary fistula. (From Stedman, 26th ed)
	Coronary Arteriosclerosis - Thickening and loss of elasticity of the coronary arteries, leading to progressive insufficiency of the arteries (CORONARY DISEASE).
	Coronary Stenosis - Narrowing or constriction of a coronary artery.
	Coronary Thrombosis - Presence of a thrombus in a coronary artery, often causing a myocardial infarction.
	Coronary Vasospasm - Spasm of the large- or medium-sized coronary arteries.
