Myocardial infarction, also known as a heart attack, is caused by an obstruction or blockage in one or more of the coronary arteries that supply blood to the heart muscle.

The aorta and pulmonary vein do not supply blood to the heart muscle, and the cardiac veins drain blood from the heart muscle.
