Myocardial infarction ( infarct ) occurs when a coronary artery supplying the
left ventricle becomes occluded by a thrombus ( blood clot ), so an area of the heart is without a blood supply. The terms myocardial infarct and coronary occlusion and heart attack refer to the same serious problem. The heart derives its own blood supply from the coronary arteries, so when a coronary artery or one of its major branches is occluded, an area of yhe myocardium is without blood supply. The infarcted area is primarily in the left ventricle, and deadly arrythmias may result. Scrie-ţi rezumatul aici.
