This disease is also known as heart attack and it consists in the obstruction of large epicardial coronary arteries that supply blood and oxygen to the heart. The World Health Organization (WHO) estimated in 2012 that out of the 17.5 million people who died from cardiovascular disease, 7. 4 million suffered a heart attack.
An acute myocardial infarction occurs when the flow of oxygen-rich blood is interrupted and blood can’t reach a portion of the heart’s muscle; without any blood flow, the heart becomes damaged. Regularly, heart attacks are caused by a clot located on top of a cholesterol plaque called atherosclerosis, which leads to an interruption of blood flow to the coronary arteries which transport oxygen and blood.
