A heart attack, also known as a myocardial infarction, occurs when the blood flow to a part of the heart muscle is blocked, usually by a blood clot.
This blockage prevents oxygen and nutrients from reaching that part of the heart, which can cause damage to the heart muscle.
Common symptoms include chest pain or discomfort, shortness of breath, nausea, cold sweats, and pain in the arms, neck, jaw, or back.
It's a medical emergency that requires immediate attention to minimize damage to the heart muscle and improve the chances of recovery.
