Myocardial Infarction The heart is arguably the most vital organ in the human body. What happens when the heart muscle begins to die' A myocardial infarction (or heart attack) is the death of a part of the heart muscle due to its sudden loss of blood supply. What causes this sudden loss of blood supply' What is reperfusion' What is a PTCA' What causes the heart muscle to lose its blood supply' Usually, the loss of the heart’s blood supply is caused by the total blockage of a coronary artery by a blood clot on a cholesterol plaque in the artery. Cholesterol is a fatty chemical which is a part of the outer lining of cells in the body. Cholesterol plaque is the formation of a hard substance within the walls of the artery caused by deposits of cholesterol over time. This process begins while a person is in their teenage years. If a person begins eating unhealthy foods at a young age, he or she will be prone to a heart attack at a later age. What is reperfusion' Reperfusion is the main goal in treating heart attack victims.
