What do you need to know about coronary arteries bypass grafting?
Coronary artery bypass grafting (CABG) is a type of surgery that is performed to improve the flow of blood to the heart. The surgery is used by surgeons for the treatment of Coronary Heart Disease (CHD). This is a disease in which plaque or a waxy substance gets built up within the coronary arteries.
These arteries are responsible for supplying oxygen-rich blood to the heart. With the passage of time, the built-up plaque has the tendency to either harden up or break open (rupture). This narrows down the coronary arteries, and cuts down on the flow of blood to the heart itself which can cause chest discomfort or chest pain known as angina.
