A heart attack occurs when blood flow to a part of the heart muscle is suddenly blocked. This usually happens when a coronary artery becomes obstructed by a blood clot forming on a buildup of plaque.
Without oxygen-rich blood, the heart muscle can become damaged. Immediate medical treatment is essential to restore blood flow and limit injury to the heart.
Symptoms may vary and sometimes appear gradually rather than suddenly.
If you suspect a heart attack, call emergency services immediately. Early treatment greatly improves outcomes and reduces long-term heart damage.
After a heart attack, treatment often includes medications, lifestyle changes, and sometimes procedures such as stenting or bypass surgery to restore blood flow and protect heart health.
