Coronary Heart Disease


What is Coronary Artery Disease?

Coronary arteries are responsible for providing the Heart with Oxygen. When cholesterol starts building up on the arteries of the heart, it narrows it down to such extent that the transmission of blood through them becomes extremely difficult, thus resulting id Coronary Artery Disease (CAD). It is also called Coronary Heart Disease (CHD). Uncontrolled CHD, i.e., when the arteries have been narrowed down to such extent, that the flow of the blood is at an extremely slow pace, then in such a case the heart muscles will start to die if not restored, this will eventually lead to a Heart Attack.
