Solution

A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. "Myo" means muscle, "cardial" refers to the heart, and "infarction" means death of tissue due to lack of blood supply.

A network of blood vessels known as coronary arteries surround the heart muscle and supply it with blood that is rich in oxygen and nutrients. The heart muscle needs this continuous supply of oxygen and nutrients to function.

A heart attack occurs when a coronary artery becomes suddenly blocked, stopping the flow of blood to the heart muscle and damaging it.
