What is a heart attack?

Blocked artery landscapeA heart attack is what happens when a blood clot stops blood from getting to part of your heart muscle. This stops the heart muscle from getting enough oxygen, and so that part of your heart muscle dies.

Different people may have different symptoms and warning signs, for example women and people with diabetes.

Several things make it more likely you will have a heart attack, including several lifestyle factors. By changing your lifestyle you can help to lower your risk of a heart attack.
