Heart attacks are serious medical emergencies that require immediate attention from a doctor. You could lower your risk of a deadly heart attack, which is also known as a myocardial infarction, by regularly going walking, swimming, or dancing.

Heart attacks are caused by a lack of blood reaching the heart.

Without enough blood, the heart could become seriously damaged - and it may even be life-threatening.

A heart attack could also be a symptom of coronary heart disease, which is where fatty deposits build up in the arteries, which limits the amount of blood reaching the heart.

One of the best ways to protect against heart attacks and heart disease is to take up certain exercises.
