What is CABG?
Coronary artery bypass graft (CABG) surgery is a type of surgery that improves blood flow to the heart. It is used to treat people who have severe coronary heart disease (CHD). The surgery involves taking a blood vessel from another part of the body and grafting it to the blocked coronary artery. The grafted artery then bypasses the blocked portion of the coronary artery and increases the flow of oxygen-rich blood to the heart muscle. CABG is recommended by the American College of Cardiology Foundation (ACCF) and American Heart Association (AHA) in the Hillis et al. 2011 ACCF/AHA CABG Guideline.
