As a medical professional, I can tell you that the onset and duration of a heart attack can vary significantly from person to person. A heart attack, or myocardial infarction, occurs when blood flow to the heart muscle is blocked, usually by a blood clot. The symptoms of a heart attack can include shortness of breath, chest pain (which may radiate to the jaw, shoulder, or arm), irregular heartbeats, nausea, or vomiting. It's important to note that the duration of symptoms is a critical factor in determining the severity and potential outcome of a heart attack. While some symptoms may last for only a few seconds or minutes, the American Heart Association indicates that chest discomfort or pain during a heart attack typically lasts for 15 minutes or longer. If these symptoms persist beyond this time frame, it's crucial to seek immediate medical attention, as it could be a sign of a heart attack.
