Coronary Thrombosis

Coronary thrombosis is the occlusion of one of the two coronary arteries, or a branch, by a thrombus. In plain English, it is when one of these heart arteries get clogged up by a blood clot. The coronary arteries and its branches supply oxygenated blood, which comes from the left ventricle, to the myocardium (heart muscle). A coronary thrombosis is the cause of a myocardial infarction, which is the medical term for a heart attack. Why? Because the blockage of one of these blood vessels leads to the death of the heart muscle, causing necrosis as the heart is no longer able to pump the blood efficiently, ending up in fibrillation.
