Before Coronary Artery Bypass Graft
Coronary artery bypass graft (CABG)
is open heart surgery to clear blocked arteries in your heart. CABG surgery improves blood flow to your heart by bypassing (sending blood around) the blocked part of an artery. This restores blood flow to your heart and helps prevent a heart attack.
Contact your healthcare provider if:
- You have a fever or symptoms of the flu the day before, or the day of, your surgery.
- You have questions or concerns about your condition or care.
may be needed several days before or on the day of surgery. You may need blood tests, an electrocardiogram (EKG), or an echocardiogram. You may also need a cardiac catheterization or a coronary angiogram. These tests will help your healthcare provider see where the blood flow is blocked and help him plan your surgery.
Eating and drinking before surgery:
Your healthcare provider may tell you not to eat or drink anything after midnight on the day of your surgery.
Medicines before surgery:
Your healthcare provider will tell you what medicines to take or not take on the day of your surgery. Talk to your healthcare provider several days before your surgery about any medicines that you take regularly:
- You may need to stop taking blood thinner, aspirin, or NSAID medicine several days before the surgery. This may prevent bleeding during and after your surgery.
- You may need to stop taking certain vitamins or herbal supplements several days before the surgery. Some vitamins and herbal supplements may increase your risk for bleeding and other complications.
- If you have diabetes, ask about your insulin. On the morning of your surgery, you may need to skip your dose or take a smaller dose. This will prevent your blood sugar level from going too low. Do not take your oral diabetic medicine on the morning of your surgery.
- Ask your healthcare provider if you should take your blood pressure or heart medicine before your surgery. Do not stop your medicine without talking to your healthcare provider.
- Take any medicine you were told to take with a sip of water on the morning of your surgery.
Blood donation before surgery:
You may be able to donate your own blood before surgery. This is called autologous blood donation. You may also ask a family member or friend with the same blood type to donate blood for you. This is called directed blood donation.
Weight loss before surgery:
You may need to lose weight before your surgery. This may decrease the stress on your heart and your risk for complications during or after surgery. Talk to your healthcare provider if you need help to lose weight.
Quit smoking before surgery:
Nicotine and other chemicals in cigarettes and cigars can damage your heart and lungs. Smoking may prevent healing and increase your risk for complications during or after your surgery. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
What to expect after surgery:
- You may spend 1 to 3 days in an intensive care unit (ICU). Healthcare providers will closely monitor your breathing, blood pressure, oxygen levels, and heart rate. They will also watch for any complications. You may need several medicines to control your blood pressure and heart rate, and to prevent blood clots. You may also need a blood transfusion. After you leave the ICU, you may need to spend 3 to 5 days in the hospital before you can go home.
- You may wake up from surgery with an endotracheal tube (ET tube). An ET tube is inserted through your mouth and into your lungs. It is attached to a ventilator. A ventilator is a machine that gives you oxygen and breathes for you when you cannot breathe well on your own. Healthcare providers will remove the ET tube when you are awake, you can breathe on your own, and your heart is working correctly.
- When your ET tube is removed, it is important to cough, and deep breathe. This will decrease your risk for a lung infection. It is also important to walk around as soon as healthcare providers tell you it is okay. This will help prevent blood clots.
- You may have a drain in your bladder to empty your urine, and a drain in your chest to prevent blood from forming around your heart. You may have several IVs in your arm, neck, or chest. You may also have a temporary pacemaker to control your heartbeat.
- You may have pain in your chest after surgery. Healthcare providers will give you pain medicine. They will also show you how to use a splint when you need to cough and turn in bed. A splint is a pillow or soft object that you can press lightly against your chest. This will decrease pain when you move or cough.
- You may not be able to eat right away. You will be given ice chips and then clear liquids. If you do okay with those, you will be able to eat solid foods.
Cardiac rehabilitation (rehab):
You will need to go to cardiac rehab after surgery. Rehab is a program run by specialists who will help you safely strengthen your heart and prevent more heart disease.
