  A heart attack, medically known as a myocardial infarction , occurs when the blood flow to a part of the heart is blocked for a prolonged period, resulting in damage or death of the heart muscle. This blockage is typically caused by the buildup of plaque (a combination of fat, cholesterol, and other substances) in the coronary arteries, which supply oxygen-rich blood to the heart muscle. Without adequate blood flow, the affected part of the heart muscle is deprived of oxygen and nutrients, leading to tissue damage. Heart attacks can range in severity from mild to life-threatening, depending on the extent of the blockage and the duration of reduced blood flow. Prompt medical intervention is crucial to restore blood flow to the affected area of the heart and minimize long-term damage. Symptoms of a heart attack can vary but often include chest pain or discomfort, shortness of breath, nausea, lightheadedness, and pain or discomfort in the arms, back, neck, jaw, or stomach.
