Quizplus · Accepted Answer

Myocardial infarction, also known as a heart attack, occurs when the blood flow to the heart muscle is blocked, resulting in damage or death of the heart tissue. This can occur due to a buildup of plaque in the arteries or a blood clot, leading to ischemia (lack of blood supply) and ultimately, myocardial infarction. Angina pectoris is chest pain or discomfort caused by reduced blood flow to the heart, but it does not result in permanent damage to the heart muscle. Cardiac arrest is a sudden loss of heart function, which can be caused by a variety of factors including heart attack, but it is not the same as myocardial infarction.
