Myocardial infarction causes pain that starts in the chest and radiates into the shoulder and arm. A clot obstructs a coronary artery resulting in an infarction or heart attack, blood flow is severely interrupted and the heart is no longer supplied with oxygen. Hypercholesterolemia and physical inactivity are two factors that encourage the development of atherosclerotic plaques.
