The heart is a muscle that pumps blood throughout the body. Similar to other muscles, the heart needs a continuous supply of blood to work properly. With aging, the heart compensates for clogged vessels by working harder and raising blood pressure. Heart disease refers to conditions that prevent the heart from working correctly. Common types of heart disease include heart attack, abnormal heartbeat, weak heart muscle, heart disease from infection and damaged heart valves.
