chosen: What causes someone to have a heart attack?

chosen: The most common cause of a heart attack is a blockage in one or more of the coronary arteries. The blockage is caused by fatty deposits, or plaque, that builds up inside the arteries, making it difficult for oxygen-rich blood to reach the heart muscle. Other factors that can increase a person’s risk of heart attack include smoking, high cholesterol, diabetes, high blood pressure, physical inactivity, excess weight, and stress.
