Coronary heart disease (CHD), also called coronary artery disease (CAD) is leading cause of death and morbidity in men and women worldwide. CAD is caused due to formation of plaque in the arteries that supply the heart with blood. Plaque is made of fatty material, calcium, and scar tissue. The arteries supply the heart muscle (myocardium) with oxygen and other nutrients it needs to pump blood and remain healthy.
