This happens when most of the heart gets blood it needs through the two coronary arteries. When the arteries are blocked, the heart may die due to the reason of the lack of blood. Coronary artery disease is traceable to atherosclerosis. The arteries changed from being smooth and elastic to rough, inflexible and lastly smaller as compared to before. As a result, being narrow, the volume of blood that can be transported is reduced. Soon, the coronary arteries are clogged by cholesterol and fat deposits and therefore, resulting to the obstruction of the blood flow.During a heart attack, the blood flow to a particular part of the heart that may be blocked, and hence the region of the heart muscle dies. The body can recover if only a small area of muscle dies but extensive muscle damage is fatal.
