What is a heart attack, and what are its warning signs?
Asked by Male, 51 · 6 months ago
A heart attack, or myocardial infarction, occurs when blood flow to a part of the heart is blocked, usually due to a blood clot in the coronary arteries, causing damage to the heart muscle. Common warning signs include chest pain or pressure (often spreading to the arm, neck, jaw, or back), shortness of breath, nausea or vomiting, sweating, lightheadedness, and sudden fatigue. Some people, especially women, older adults, and people with diabetes, may experience atypical symptoms such as unusual discomfort, indigestion, or mild pain. Immediate medical attention is crucial if a heart attack is suspected, as early treatment can save lives and reduce heart damage.
