According to the World Health Organization about 12% of all death in the world is related to the heart disease and it is one of the leading disease in the developed country. Heart attack also known as the myocardial infarction is defined as the interruption of blood supply to a part of a heart and result in cell ischaemia and eventually cell death.
Causes of Heart Attack
Many scientist believe that heart attack is caused by building up of cholestrol in the wall of the artery (vulnerable atherosclerosis) supplying the heart(coronary artery). This cholestrol will eventually become hardens and formed plaque over the wall of the artery and this result in less amount of blood flow to that area. When the plaque ruptures, it will block small artery of the heart and caused a heart attack.
