coronary

encircling in the manner of a crown; said of anatomical structures such as vessels, ligaments, or nerves.
coronary arteries two large arteries that branch from the ascending aorta and supply all of the heart muscle with blood (see also table of arteries).
 A view of the coronary arterial system. The arteries serving the posterior aspect of the myocardium are shown here in a lighter shade.
coronary artery disease (CAD) atherosclerosis of the coronary arteries, which may cause angina pectoris, myocardial infarction, and sudden death. Both genetically determined and avoidable risk factors contribute to the disease; they include hypercholesterolemia, hypertension, smoking, diabetes mellitus, and low levels of high density lipoproteins (HDL).
coronary heart disease (CHD) ischemic heart disease.
coronary occlusion the occlusion, or closing off, of a coronary artery, usually caused by a narrowing of the lumen of the blood vessels by the plaques of atherosclerosis. Sometimes a plaque may rupture and release vasoactive or thrombogenic substances that lead to clot formation. If there is adequate collateral circulation to the heart muscle at the time of the occlusion, there may be little or no damage to the myocardial cells. When occlusion is complete, however, with no blood being supplied to an area of the myocardium, myocardial infarction results.
