If you're like most people, you think that heart disease is a problem for others. But heart disease is the number one killer in the U.S. It is also a major cause of disability. There are many different forms of heart disease. The most common cause of heart disease is narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself. This is called coronary artery disease and happens slowly over time. It's the major reason people have heart attacks. Other kinds of heart problems may happen to the valves in the heart, or the heart may not pump well and cause heart failure.
Heart disease is any condition that keeps your heart from functioning at its best or causes a deterioration of the heart's arteries and vessels. Coronary heart disease (CHD), also known as coronary artery disease, is the most common form of heart disease, affecting 12.6 million people in America. If you are diagnosed with CHD, it means you have atherosclerosis, or hardening of the arteries on the heart's surface.
