Heart Disease: Should I Have Bypass Surgery?
Get the facts
Coronary artery bypass graft surgery helps improve blood flow to the heart in people with severe coronary artery disease. The surgeon connects, or grafts, a healthy artery or vein from another part of your body to the blocked coronary artery. The grafted blood vessel goes around (bypasses) the blocked part of the artery. This provides a new pathway for blood to your heart.
The goals of bypass surgery are to:
Bypass surgery does a good job of treating coronary artery disease, but it is not a cure. Bypass surgery doesn't change the way arteries harden or narrow because of heart disease. And even after surgery, you can still get new blockages. These can occur in the new blood vessels that bypass the blocked arteries, as well as in the original coronary arteries.
You'll receive anesthesia before the surgery that will make you sleep. In most cases, bypass surgery is open-chest surgery. During the surgery, your chest will be open and your heart exposed. The surgeon makes a large cut, or incision, in the middle or side of your chest. He or she may cut through your breastbone and spread apart your rib cage.
The surgeon removes a healthy blood vessel—often from the leg—and attaches (grafts) it to the blocked artery. The new blood vessel bypasses the blocked artery to increase blood flow to the heart. You may need just one bypass graft, or you may need more. Some people have as many as two, three, or even four (double, triple, or quadruple bypass surgery). How many grafts you need depends on how many arteries are blocked and where.
When the surgery is complete, the doctor may use wire to put your rib cage back together and stitches to close the incision. The surgery can take 3 to 6 hours. You will stay in the hospital at least 3 to 8 days after the surgery. It can take 4 to 6 weeks to recover at home. Most people are able to return to work within 1 to 2 months after surgery.
Not everyone with coronary artery disease needs bypass surgery. Some people can be helped by angioplasty with stents. Others use medical therapy, which involves making lifestyle changes and taking medicines. Some people use both of those treatments. Your doctor is likely to recommend bypass surgery only if you will benefit from it and if those benefits are greater than the risks.
Your doctor may advise bypass surgery if:
Your choice may depend on the number of arteries that are blocked or which arteries are blocked. Talk with your doctor about the best treatment for you. The best treatment for you may also depend on your age, your health, and how much your chest pain is affecting your quality of life.
Bypass surgery has been done for more than 40 years. In the United States, it is done more often than any other major surgery. But it has some serious risks.
The risks of bypass surgery include:
Other risks include return of angina, problems from anesthesia, and infections at the site of the chest incision. Some people also have memory loss and trouble thinking clearly. These problems are most common in older people and tend to improve several months after surgery.
The chances of having a serious problem with bypass surgery are higher if you are older than 70. Your risk is also higher if you have other problems such as diabetes, kidney disease, lung disease, or peripheral arterial disease. It's important to talk with your doctor to find out how your health affects your risk.
Lifestyle changes and medicines
The success of bypass surgery also depends on you. If you smoke and don't quit, you won't get the most benefit from bypass surgery. You may need to make some other big changes, like eating right and getting regular exercise. These changes will help your bypass grafts last and stay open longer. They will also give you the best chance of living a longer, healthier life.
If you are taking medicines for angina, to lower cholesterol, or to control blood pressure, it’s also important to take these every day. Along with lifestyle changes, these medicines can help you get the most benefit from bypass surgery.
Bypass surgery is not a cure for heart disease. That's why all of these things—eating right, not smoking, getting exercise, and taking medicines—are so important. Without them, you raise your risk of getting new blockages and needing another surgery.
Other choices for you and your doctor to talk about are:
Bypass surgery offers more relief from chest pain and other symptoms and the chance at a longer life compared with making lifestyle changes and taking medicines alone.
Bypass surgery and angioplasty with stents have similar results in terms of improving your chances of living a longer life. But bypass surgery may help keep your arteries open longer.
If you have diabetes, bypass surgery may be a better choice than angioplasty or medical therapy. But your treatment also depends on your health, how serious your heart disease is, and if medicines are working to relieve your symptoms.
Ask your doctor what you can expect to happen if you have bypass surgery, compared with having other kinds of treatment like medical therapy or angioplasty with stents. Your doctor should be able to tell you why bypass surgery would be a good choice. Sometimes it helps to see another doctor to get a second opinion.

Personal stories
Are you interested in what others decided to do? Many people have faced this decision. These personal stories may help you decide.
These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.
I never thought twice about whether coronary artery bypass surgery was right for me. After my heart attack, I wanted to do everything I could to get healthier. I started exercising and eating better and taking medicines. But it didn't help my chest pain, and I couldn't do all the things I wanted to do. I knew it was time to have the surgery.
Alan, age 70
My doctor tells me I need to do something about my heart. He wants me to have heart surgery. I guess my arteries are blocked up. My chest hurts when I'm out with the dog. But I'm not sure I have what it takes to come back after surgery. I have my hands full keeping my high blood pressure under control. I'm going to ask my doctor if there is something else I can do that isn't as risky but would give me some relief.
Saul, age 85
When my doctor told me I had to have bypass surgery, I asked a lot of questions. He does so many of these surgeries every year. I know he thought a bypass would be best for me. But I had to make sure. I'm afraid of all the risks. So I asked another cardiologist what he thought. He looked at my angiograms. We talked about whether angioplasty with stents or making changes to the way I eat and the medicines I take could work. It turns out bypass surgery probably is the best choice for me. At least now I know why.
Gloria, age 67
I love to cook and eat. I'm not a big fan of exercise, but I try to take a walk once a week. Everybody in my family has really high cholesterol, including me. I never took it seriously. But then I started having chest pains at work. My doctor says I have severe heart disease, but that I'm lucky. If I make some big changes in the way I eat, and if I take medicine and exercise every day, I might be able to avoid surgery. It's worth a try.
