A heart stroke, commonly known as a heart attack or myocardial infarction, occurs when there is a sudden blockage of blood flow to a part of the heart muscle. This blockage is often due to the buildup of fatty deposits (plaques) in the coronary arteries, which supply oxygen-rich blood to the heart. Symptoms of a heart stroke can include chest pain or discomfort, shortness of breath, nausea, sweating, and pain or discomfort in the arms, back, neck, jaw, or stomach. Prompt medical attention is crucial to minimize heart damage and prevent complications such as heart failure or cardiac arrest. Treatment may involve medications to dissolve or prevent blood clots, procedures such as angioplasty to restore blood flow, and lifestyle changes to reduce the risk of future heart problems.
