Coronary Artery Bypass Grafting

A coronary artery bypass graft (CABG) is a surgery to restore blood flow to the heart muscle. This is done by using blood vessels from other parts of the body to make a new route for blood to flow around blocked coronary (heart) arteries.

  • What to Expect

  • Reasons for Procedure

    Atherosclerosis
    is a disease of the arteries. Cholesterol and fatty deposits build up on the walls of the arteries. This restricts blood flow. When the buildup happens in the heart, it may lead to chest pain, called
    angina
    , or
    heart attack
    . Lifestyle changes and medicines can be used to treat atherosclerosis. When the blockage gets too severe, CABG is done to re-establish blood supply to the heart muscle. It is often recommended in cases of:

    • Severe blockage in the main artery or in several blood vessels that supply blood to the heart

    • Persistent
      angina
      that does not improve with other treatments

  • Possible Complications

    If you are planning to have a CABG, your doctor will review a list of possible complications, which may include:

    • Infections
    • Blood clots
    • High blood pressure
      or low blood pressure
    • Bleeding
    • Stroke
    • Damage to other organs, such as the kidneys
    • Irregular heart rate
    • Death

    Some factors that may increase the risk of complications include:


    • Lung disease, especially
      chronic obstructive pulmonary disease (COPD)
      (
      emphysema
      )
    • Prior
      heart attack
      or bypass surgery
    • Advanced age
    • Severe condition (the need to have emergency surgery)
    • Obesity
    • Diabetes
    • Smoking
    • High blood pressure
    • Thyroid disease
    • Depression
