How will coronary artery disease lead to a heart attack?

Causative: Coronary artetiosclerosis leads to plaque buildup which in turn eventually causes a stenosis in the coronary. Acute plaque thorombosis leads to acute coronary closure with the obvious myocardial ischemic necrosis. Emergency coronary revascularization within minutes of the occlusion re establishes blood flow and rescues the heart muscle that has not perished.Heart muscle that dies is gone for good.
