A heart attack occurs when one or more of your coronary arteries become blocked. Over time, a coronary artery can narrow from the buildup of various substances, including cholesterol (atherosclerosis). This condition, known as coronary artery disease, causes most heart attacks. During a heart attack, one of these plaques can rupture and spill cholesterol and other substances into the bloodstream. A blood clot forms at the site of the rupture. If large enough, the clot can completely block the flow of blood through the coronary artery.
Both strokes and heart attacks occur when the blood supply to that part of the body is blocked or interrupted. Strokes occur in the brain, while heart attacks are specific to the heart muscle. Both can be caused when blockages cut off the blood supply and the tissues starves for oxygen and other nutrients.
