What happens during a heart attack, and how can I recognise the signs beforehand?
A heart attack, also known as a myocardial infarction, happens when the heart?s blood supply is blocked, often by a clot, causing damage to the heart muscle. Common warning signs include chest pain or tightness, shortness of breath, nausea, or pain that spreads to the arm, neck, or jaw. You can lower your risk by keeping your blood pressure, cholesterol, and blood sugar under control and maintaining a healthy lifestyle. If you experience any concerning symptoms, seek medical attention immediately.
