About 10% of patients who are admitted to emergency departments with chest pain every year are diagnosed with heart attack. AMI is a condition that can be due to ischemic heart disease or coronary artery disease in conjunction, and it becomes manifest when an atherosclerotic plate ruptures and a developing thrombus occludes the coronary artery totally or partially, restricting blood access to the heart. In  this case,  the  opening of the  occluded coronary  artery  is usually  provided by inserting a stent. However, when stents are insufficient, coronary bypass is performed by cardiac pulmonary bypass surgery using the left internal mammary artery or saphenous vein to maintain regular nourishment of the heart.
