What is Coronary Artery Bypass Grafting?

Coronary artery bypass grafting (CABG) is a surgical procedure that improves blood flow to the heart. This procedure is used to treat people with severe coronary heart disease (CHD), a disease where plaque builds up inside the coronary arteries causing the arteries to narrow and reduce the flow of blood to the heart.

How Does CABG Work?

CABG is one treatment for coronary heart disease. During CABG, a healthy artery or vein from the body is connected, or grafted, to the blocked coronary artery. The grafted artery or vein bypasses the blocked portion of the coronary artery. This creates a new path for blood to flow to the heart muscle. Surgeons can bypass multiple coronary arteries at one time.

Reasons for CABG

CABG may be the best treatment option if you have blockages in the heart that can't be treated with angioplasty. Below are some other reasons to get coronary artery bypass grafting.

  • Improve your quality of life and reduce angina and CHD symptoms
  • Resume an active lifestyle
  • Improve the pumping action of your heart if it has been damaged by a heart attack
  • Lowering the risk of a heart attack (in some patients, such as those who have diabetes)
  • Improving your chance of survival
