Coronary Artery Bypass Surgery

How It Is Done

What To Expect

Right after surgery

You will go to the intensive care unit (ICU) after surgery. You will probably stay in the ICU for 1 or 2 days before you go to your regular hospital room. In the ICU, you will likely have:

• Continuous monitoring of your heart.
• A tube to help with breathing for up to a few hours.
• A stomach tube that removes stomach secretions until you start to eat again.
• A tube (catheter) to drain the bladder and measure urine output.
• IV tubes in your arms to get fluids, nutrition, and medicine.
• A thin tube in a vein in your neck that keeps track of your heart.
• A thin tube in a blood vessel in your arm to measure blood pressure.
• Several thin wires coming out of your chest. These help keep your heartbeat steady.
• Chest tubes. These tubes drain the chest cavity of fluid and blood (which is temporary and normal) after surgery.

Recovery

You will stay in the hospital for at least a few days after the surgery. You will feel tired and sore for the first few weeks. Your chest, shoulders, and upper back may ache. These symptoms usually get better in 4 to 6 weeks. It may take 1 to 2 months before your energy level is back to normal. You may have some swelling or pain in the area where the healthy blood vessel was taken.

You will probably be able to do many of your usual activities after 4 to 6 weeks. But for at least 6 weeks, you'll avoid lifting heavy objects and doing activities that strain your chest or upper arm muscles.

After surgery, have a heart-healthy lifestyle. This lifestyle can help lower your risk of a heart attack or stroke. It also can help the bypass last as long as possible. To have a heart-healthy lifestyle:

• Take your medicines.
• Do not smoke.
• Eat a heart-healthy diet.
• Get regular exercise.
• Stay at a healthy weight or lose weight if you need to.
• Manage other health problems such as diabetes, high blood pressure, and high cholesterol.

Smoking can make it harder for you to recover. It will raise the chances of your arteries getting narrowed or blocked again. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.

You may start a cardiac rehabilitation (rehab) program in the hospital. This program will continue after you go home. It will help you recover. And it can prevent future problems with your heart. Talk to your doctor about whether rehab is right for you.

Why It Is Done

Bypass surgery is done to treat a heart attack and coronary artery disease. Surgery might be an option if:^{footnote 1, footnote 2}

• Your left main heart artery is very narrow.
• Multiple arteries of the heart are blocked or the amount of blood flowing through them is very low.
• You are going to have surgery to repair or replace a heart valve.
• You have diabetes and two or more narrowed or blocked arteries.
• Your heart is having trouble pumping. This is called a decreased ejection fraction.

Whether surgery is an option for you also depends on your age, your health, and how much your angina is affecting your quality of life. Your doctor is likely to recommend bypass surgery only if you will benefit from it and if those benefits are greater than the risks. You and your doctor can work together to decide if you want to have surgery.

How Well It Works

Bypass surgery:

• Can relieve stable angina symptoms and improve quality of life. You may be able to do more of your daily activities.^{footnote 3}
• May help certain people who have stable angina live longer. Whether it might help you live longer depends on several things. These include your overall health and which arteries need to be bypassed. For example, the surgery may raise your chances of living longer if you have diabetes and narrowing in your heart's larger arteries.^{footnote 2, footnote 1}
• Improves blood flow to the heart muscle after a heart attack.

Risks

The risks during or soon after bypass surgery include:

• Infection.
• Kidney problems.
• Atrial fibrillation.
• Heart attack.
• Stroke.
• Short-term problems with thinking and memory. This is more common in older people. It tends to get better within several months of surgery.
• Death.

The chances of having a serious problem with bypass surgery increase with age. Your risk is also higher if you have other problems such as diabetes, kidney disease, lung disease, or peripheral arterial disease. Your doctor can help you understand what your risk for problems is.
