Coronary heart disease (or coronary artery disease) is a narrowing of the small blood vessels that supply blood and oxygen to the heart (coronary arteries). Coronary disease usually results from the build-up of fatty material and plaque ( atherosclerosis) . As the coronary arteries narrow, the flow of blood to the heart can slow or stop, causing chest pain ( stable angina ), shortness of breath, heart attack , or other symptoms.

The heart, a powerful muscle that beats over 50,000 times in one day, is fed the blood and energy it needs through small tubes called coronary arteries (see Figure 1). Coronary artery disease (CAD) is the most common cause of death and disability in the United States and other industrialized countries, and it can be manifested if these arteries become narrowed by cholesterol to about half their normal diameter (see Figure 2).
