Heart and Vascular Health Heart Attack Warning Signs By Heart and Vascular Institute, January 18, 2014 A heart attack, also called a myocardial infarction (MI), occurs when blood is blocked from flowing to the heart. When this happens, heart muscle cells don’t get the oxygen they need. This damages the heart, and cells begin to die. The damage can happen within minutes. But it can be lessened if emergency treatment is sought right away. Am I at Risk for a Heart Attack? Heart attacks can affect people of all ages.
