Introduction
A heart attack, also known as a myocardial infarction (MI), occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle. The most common cause of a heart attack is a blood clot that forms in a coronary artery. Coronary arteries are the blood vessels that supply oxygen-rich blood to the heart muscle.
Symptoms
The most common symptom of a heart attack is chest pain. The pain is often described as pressure, squeezing, or a feeling of fullness in the chest. The pain can also spread to the neck, shoulders, arms, or back.
Other symptoms of a heart attack can include:
