Detailed explanation-1: -During a heart attack, a lack of blood flow causes the tissue in the heart muscle to die. A heart attack occurs when the flow of blood to the heart is severely reduced or blocked. The blockage is usually due to a buildup of fat, cholesterol and other substances in the heart (coronary) arteries.
Detailed explanation-2: -A heart attack, also known as a myocardial infarction, happens when the flow of blood that brings oxygen to a part of your heart muscle suddenly becomes blocked. Your heart can’t get enough oxygen. If blood flow is not restored quickly, the heart muscle will begin to die. Heart attacks are very common.
Detailed explanation-3: -A heart attack (myocardial infarction) happens when one or more areas of the heart muscle don’t get enough oxygen. This happens when blood flow to the heart muscle is blocked.
