What is a heart attack, and what are its warning signs?
Asked by Female, 50 · 2 months ago
A heart attack (myocardial infarction) occurs when a part of the heart muscle is damaged or dies due to a lack of blood supply for a prolonged period. This usually happens when a coronary artery is suddenly blocked by a blood clot formed over a ruptured plaque. The key warning signs include chest pain or pressure that may radiate to the jaw, neck, back, or left arm, along with shortness of breath, sweating, and nausea. Recognising these symptoms early and calling emergency services immediately is crucial for timely treatment and better outcomes.
