Coronary artery bypass graft surgery (CABG) is a procedure used to treat coronary artery disease. Coronary artery disease (CAD) is the narrowing of the coronary arteries. These are the blood vessels that supply oxygen and nutrients to the heart muscle. CAD is caused by a build-up of fatty material within the walls of the arteries. This buildup narrows the inside of the arteries, limiting the supply of oxygen-rich blood to the heart muscle.
One way to treat the blocked or narrowed arteries is to bypass the blocked portion of the coronary artery with a piece of a healthy blood vessel from elsewhere in your body. Blood vessels, or grafts, used for the bypass procedure may be pieces of a vein from your leg or an artery in your chest. An artery from your wrist may also be used. Your healthcare provider attaches 1 end of the graft above the blockage and the other end below the blockage. Blood bypasses the blockage by going through the new graft to reach the heart muscle. This is called coronary artery bypass surgery.
Traditionally, to bypass the blocked coronary artery, your provider makes a large cut (incision) in the chest and briefly stops the heart. To open the chest, your provider cuts the breastbone (sternum) in half lengthwise and spreads it apart. Once the heart is exposed, your provider inserts tubes into the heart. This lets the blood be pumped through the body by a heart-lung bypass machine. The bypass machine is needed to pump blood while the heart is stopped.
The traditional open heart procedure is still commonly done. In many cases it may be preferred. But less invasive methods have been developed to bypass blocked coronary arteries. Off-pump procedures, in which the heart does not have to be stopped, were developed in the 1990's. Other minimally invasive procedures, such as keyhole surgery (done through very small incisions) and robotic procedures (done with the aid of a moving mechanical device), may be used.
Coronary artery bypass graft surgery (CABG) is done to treat a blockage or narrowing of 1 or more of the coronary arteries. It can restore the blood supply to your heart muscle when nonsurgical procedures are not a choice.
Along with a review of your health history, your provider may do a complete physical exam to make sure you are in otherwise good health before having the procedure. You may need blood tests or other diagnostic tests.
Tell your provider if you have a history of bleeding disorders or if you are taking any blood-thinning medicines, aspirin, or other medicines that affect blood clotting. You may be told to stop some of these medicines before the procedure. Ask which medicines to take, and which to stop, and when you should stop taking them.
A healthcare professional will insert an IV (intravenous) line in your arm or hand. Other catheters will be put in your neck and wrist to monitor your heart and blood pressure, as well as to take blood samples.
The anesthesiologist will continuously keep track of your heart rate, blood pressure, breathing, and blood oxygen level during the surgery. Once you are sedated (put into a deep sleep), a breathing tube will be put into your throat and you will be connected to a ventilator, which will breathe for you during the surgery.
Once all the tubes and monitors are in place, your provider will make cuts in 1 or both of your legs or 1 of your wrists. This is to access the blood vessel(s) to be used for the grafts. They will remove the vessel(s) and close those incision(s).
To sew the grafts onto the very small coronary arteries, your healthcare provider will need to stop your heart temporarily. Tubes will be put into the heart so that your blood can be pumped through your body by a heart-lung bypass machine.
When the heart has been stopped, the provider will do the bypass graft procedure by sewing one end of a section of vein over a tiny opening made in the aorta, and the other end over a tiny opening made in the coronary artery just below the blockage. If your provider uses the internal mammary artery inside your chest as a bypass graft, the lower end of the artery will be cut from inside the chest and sewn over an opening made in the coronary artery below the blockage.
You may need more than 1 bypass graft done, depending on how many blockages you have and where they are located. After all the grafts have been completed, the provider will closely check them as blood runs through them to make sure they are working.
Once the bypass grafts have been checked, the provider will let the blood circulating through the bypass machine back into your heart and they will remove the tubes to the machine. Your heart may restart on its own, or a mild electric shock may be used to restart it.
The provider will do the bypass graft procedure by sewing one end of a section of vein over a tiny opening made in the aorta, and the other end over a tiny opening made in the coronary artery just below the blockage.
After the surgery, you may be taken to the recovery room and then the intensive care unit (ICU) to be closely monitored. Machines will constantly display your electrocardiogram tracing, blood pressure, other pressure readings, breathing rate, and your oxygen level. Coronary artery bypass surgery (CABG) requires a hospital stay of at least several days.
You will most likely have a tube in your throat to help with breathing through a ventilator (breathing machine) until you are stable enough to breathe on your own. As you continue to wake up from the anesthesia and start to breathe on your own, your healthcare provider can adjust the breathing machine to allow you to take over more of the breathing. When you are awake enough to breathe completely on your own and you are able to cough, your provider will remove the breathing tube. In most cases, the breathing tube is removed soon after the operation, usually the same day or by early the next morning. Your provider will also remove the stomach tube at this time.
After the breathing tube is out, a nurse will help you cough and take deep breaths every couple of hours. This will be uncomfortable due to soreness, but it's very important that you do this to keep mucus from collecting in your lungs and possibly causing pneumonia. Your nurse will show you how to hug a pillow tightly against your chest while coughing to help ease the discomfort.
The surgical incision may be tender or sore for several days after a CABG procedure. Take a pain reliever for soreness as recommended by your provider. Aspirin or certain other pain medicines may increase the chance of bleeding. Be sure to take only recommended medicines.
Your provider may deliver medicines through the IV to help your blood pressure and your heart, and to control any problems with bleeding. As your condition stabilizes, they will gradually decrease and then stop these medicines.
Once your provider removes the breathing and stomach tubes and you are stable, you may start to drink liquids. You can gradually include more solid foods as you can tolerate them. Your nurse will help you sit up on the side of the bed and dangle your feet. If you are able to do this, the nurse will help you sit up for a while in a chair.
When your provider determines that you are ready, you will be moved from the ICU to a postsurgical nursing unit. Your recovery will continue there. You can gradually increase your activity as you get out of bed and walk around for longer periods. This helps prevent complications from the surgery, such as pneumonia or blood clots in your legs. You can eat solid foods as soon as you can tolerate them.
Once you are home, it will be important to keep the surgical area clean and dry. Your healthcare provider will give you specific bathing instructions. They will remove the stitches or surgical staples during a follow-up office visit, if they were not removed before leaving the hospital.
When your recovery time ends, your provider may advise that you start a cardiac rehab (rehabilitation) program. This helps you get back to a normal lifestyle. Cardiac rehab starts in the hospital with simple walking. It goes on to help you with a regular exercise routine and a healthy diet. These healthier habits can prevent heart problems in the future.
Additionally, NIH annually submits to the President and then Congress a Professional Judgment Budget that estimates additional future funding needed to most effectively leverage promising scientific opportunities in dementia research. This estimate is often referred to as a "bypass budget" because it is presented without modification through the traditional federal budget process.

Once you are unconscious, the heart surgeon will make an 8 to 10-inch (20.5 to 25.5 cm) surgical cut in the middle of your chest. Your breastbone will be separated to create an opening. This allows your surgeon to see your heart and aorta, the main blood vessel leading from the heart to the rest of your body.
You may need this procedure if you have a blockage in one or more of your coronary arteries. Coronary arteries are the vessels that supply your heart with oxygen and nutrients that are carried in your blood.
When one or more of the coronary arteries becomes partly or totally blocked, your heart does not get enough blood. This is called ischemic heart disease, or coronary artery disease (CAD). It can cause chest pain (angina).
Coronary artery bypass surgery can be used to improve blood flow to your heart. Your health care provider may have first tried to treat you with medicines. You may have also tried exercise and diet changes, or angioplasty with stenting.
After the operation, you will spend 3 to 7 days in the hospital. You will spend the first night in an intensive care unit (ICU). You will probably be moved to a regular or transitional care room within 24 to 48 hours after the procedure.
