CAD

   Coronary artery disease. CAD is a major cause of illness and death. It begins when hard cholesterol substances (plaques) are deposited within a coronary artery. These arteries arise from the aorta adjacent to the heart and supply the heart muscle with blood that is rich in oxygen. They are called the coronary arteries because they encircle the heart in the manner of a crown.
