A coronary heart assault takes place when the drift of blood to the coronary heart is blocked. The blockage is most often a buildup of fat, cholesterol and different substances, which form a plaque inside the arteries that feed the coronary heart (coronary arteries).
The plaque eventually breaks away and paperwork a clot. The interrupted blood flow can harm or wreck part of the coronary heart muscle.
