CABG is used to treat people who have severe CAD. CAD is the narrowing of the coronary arteries—the blood vessels that supply oxygen and nutrients to the heart muscle. This condition is caused by a buildup of fatty material called plaque within the walls of the arteries. Over time, that plaque—made up of fat, cholesterol, calcium, and other substances found in the blood—will become

Jul 15, 2019 · The coronary arteries are the blood vessels that supply blood to the myocardium (heart muscle). Because it must work continuously (as opposed to other muscles of the body, which are often at rest), the heart muscle has a very high requirement for oxygen and nutrients and therefore requires a very reliable, continuous supply of blood.
