Coronary Heart Disease (CHD)

Coronary Heart Disease is an impairment of heart functions due to inadequate blood flow to the heart. Coronary heart disease is a major cause of premature death in several countries across the world. The heart governs the circulatory system and nourishes the whole body. But the heart itself needs blood supply for proper functioning and this is delivered by a pair of coronary arteries. Over a period of time due to the deposition of fatty material and plaque, they get narrowed. This results in a condition called atherosclerosis characterized by inadequate blood supply to the heart muscle.
