EN-B-CA-CN1-V49_20251215_115718_v1

What is Coronary Artery Bypass Grafting (CABG)?

Coronary Artery Bypass Grafting (CABG) is a common heart surgery. Doctors use it to treat blocked or narrowed heart arteries. When arteries get blocked, blood cannot reach the heart muscle. As a result, you may feel chest pain or even have a heart attack. CABG creates a new path for blood to flow to your heart. According to the American Heart Association, CABG is one of the most effective ways to improve blood flow and relieve symptoms.

Who Needs CABG?

Not everyone with heart disease needs CABG. However, your doctor may suggest this surgery if:

  • You have severe chest pain from blocked arteries.
  • Other treatments, like medicine or stents, have not worked.
  • You have more than one blocked artery.
  • Your heart function is weak due to poor blood flow.
  • You have diabetes and several blocked arteries.

    • Usually, your doctor will run tests to decide if CABG is right for you. These tests may include an angiogram or a stress test.

    How is CABG Performed?

    During the heart bypass procedure, a surgeon uses a healthy blood vessel from your leg, arm, or chest. Then, they attach it to the blocked artery. This new path lets blood flow around the blockage. Most CABG surgeries take three to six hours. Often, you will be under general anesthesia, so you will not feel pain.

    There are two main types of CABG:

  • Traditional CABG: The surgeon opens the chest and stops the heart for a short time.
  • Off-pump CABG: The surgeon works on the heart while it is still beating.

    • Your doctor will choose the best method for you. The choice depends on your health and the number of blocked arteries.

    Benefits of CABG

    CABG surgery offers many benefits. For example, it can:

  • Reduce chest pain (angina)
  • Lower the risk of heart attack
  • Improve your ability to exercise
  • Increase your quality of life
  • Help you live longer, especially if you have severe disease

    • According to the CDC, CABG is a proven way to help people with serious heart disease.

    Risks and Possible Complications

    Like any surgery, CABG has some risks. However, most people recover well. Possible risks include:

  • Bleeding or infection
  • Blood clots
  • Stroke or heart attack
  • Problems with memory or thinking
  • Kidney problems

    • Older adults and people with other health issues may have higher risks. Still, your doctor will take steps to lower these risks. The benefits of CABG often outweigh the risks for many patients.

    Recovery After CABG

    After CABG surgery, you will stay in the hospital for about five to seven days. At first, you will be in the intensive care unit (ICU). Nurses and doctors will watch you closely. Once you are stable, you will move to a regular room.

    Here are some tips for CABG surgery recovery:

  • Follow your doctor’s instructions about medicines and wound care.
  • Start gentle walking as soon as your doctor allows.
  • Eat healthy foods to help your body heal.
  • Attend cardiac rehab if your doctor recommends it.
  • Ask for help with daily tasks at first.

    • Full recovery may take six to twelve weeks. However, most people feel better each week.

    Lifestyle Tips After CABG

    After CABG, it is important to take care of your heart. For example, you can:

  • Eat a diet low in salt, sugar, and fat
  • Exercise regularly, as your doctor suggests
  • Stop smoking, if you smoke
  • Take your medicines as prescribed
  • Manage stress with relaxation techniques

    • These steps can help prevent future heart problems. They also support your long-term health.

    Prevention of Heart Disease

    Even after CABG, you can take steps to prevent heart disease. For instance, you should:

  • Keep your blood pressure and cholesterol under control
  • Maintain a healthy weight
  • Limit alcohol intake
  • Get regular check-ups with your doctor

    • According to the World Health Organization, these habits lower your risk of heart disease and other health problems.
