Your heart is a strong muscular pump that is responsible for moving about 3,000 gallons of blood through your body every day. Like other muscles, your heart requires a continuous supply of blood to work properly. Your heart muscle gets the blood it needs to do its job from the coronary arteries.
Heart disease is the leading cause of death in the United States, causing about 1 in 4 deaths. The term “heart disease” refers to several types of heart conditions. In the United States, the most common type of heart disease is coronary artery disease (CAD), which can lead to heart attack. You can greatly reduce your risk for heart disease through lifestyle changes and, in some cases, medicine.
