Heart Attack. A heart attack happens when an area of plaque in a coronary artery breaks apart, causing a blood clot to form. The blood clot cuts off most or all blood to the part of the heart muscle that's fed by that artery. Cells in the heart muscle die because they don't receive enough oxygen-rich blood. This can cause lasting damage to your heart. Figure A is an overview of a heart and coronary artery showing damage.
