What causes a heart attack?

Your heart takes blood from the small coronary arteries that wrap around your heart.

If your heart cant get enough blood to function properly, it gets damaged from a lack of oxygen.

Heart attacks usually occur because a blockage of cholesterol plaque has built up in the coronary arteries, and then ruptured - cutting off the blood flow to the heart muscle.

The build-up of plaque is called Coronary Artery Disease, and it causes more than 90 per cent of heart attacks.
