What is a heart attack, and how can I tell if one is about to occur?
A heart attack, or myocardial infarction, occurs when blood flow to the heart is blocked, often due to a blood clot, causing damage to the heart muscle. Warning signs may include chest pain or pressure, shortness of breath, nausea, or pain radiating to the arm, neck, or jaw. The risk can be reduced by managing blood pressure, cholesterol, and diabetes, avoiding smoking, and maintaining a healthy lifestyle. Consult your doctor if you have any concerns.
