Medical Coding

Answer: D - The medical term for a heart attack, which refers to the death of heart muscle, is myocardial infarction. The term “myocardial” refers to the cardiac muscle of the heart, or the middle layer of the heart, and “infarction” refers to tissue death. So “myocardial infarction” refers to death of the tissue of the middle layer of the heart or heart muscle, which is commonly referred to as a heart attack.
