What happens if blood flow through a coronary artery is blocked?

This condition is known as coronary artery disease. Insufficient blood flow to the heart muscle can lead to symptoms of chest pain (angina). If the coronary artery becomes completely blocked, it will cause a heart attack. During a heart attack, some of the heart muscle can die from a lack of oxygen.

What happens when blood flow through one or more of the coronary arteries is blocked?

When one or more of the coronary arteries suddenly becomes completely blocked, a heart attack (injury to the heart muscle) may occur. If the blockage occurs more slowly, the heart muscle may develop small collateral blood vessels (or detours) for other coronary arteries to reroute the blood flow, and angina occurs.

What can happen if blood flow in an artery is blocked?
