Overview
CABG (say "cabbage") stands for Coronary Artery Bypass Grafting. It is a type of heart surgery that creates new routes for blood to flow around blocked or narrowed arteries in the heart. This helps more oxygen-rich blood reach the heart muscle.
Key facts
CABG is one of the most common heart surgeries worldwide.
The surgery uses a healthy blood vessel taken from another part of your body, like your leg or chest, to bypass the blocked area.
Most people feel better and have less chest pain after CABG.
Yes, CABG is a common heart surgery. Each year, many people around the world have it to treat severe coronary artery disease.
CABG is usually done for people who have severe coronary artery disease (narrowed or blocked heart arteries). This condition is more common in older adults, but it can affect anyone with risk factors like smoking, high blood pressure, or diabetes.
Symptoms
Questions about this article
Call emergency services immediately if you notice:
Chest pain that lasts more than a few minutes or goes away and comes back
Pain or discomfort in one or both arms, the back, neck, jaw, or stomach
Shortness of breath with or without chest pain
Breaking out in a cold sweat, nausea, or lightheadedness
See a doctor urgently (same day) if you notice:
⚠Chest pain that happens more often or gets worse, even at rest
⚠Symptoms that are not relieved by rest or your usual medicines
Common symptoms
Chest pain or discomfort (angina) that feels like pressure, squeezing, or fullness in the chest
Shortness of breath, especially with activity
Fatigue (feeling very tired)
Causes
Main causes
The main cause of the artery blockages that lead to CABG is coronary artery disease. This happens when a waxy substance called plaque builds up inside the arteries feeding the heart. Over time, the plaque hardens and narrows the arteries, reducing blood flow.
Risk factors
Smoking or using tobacco
High blood pressure (hypertension)
High cholesterol
Diabetes
Being overweight or obese
Not being physically active
Unhealthy diet (high in saturated fats, trans fats, and salt)
Family history of heart disease, especially at a young age
Stress or excessive alcohol use
When to see a doctor
See a doctor urgently if:
If you have new or worsening chest pain, shortness of breath, or symptoms that might signal a heart attack, call your local emergency number right away.
Book a routine appointment if:
If you have risk factors for heart disease (like high blood pressure, diabetes, or a family history), see your doctor for regular check-ups and discuss your heart health.
Many people with risk factors for heart disease never need CABG. Making healthy lifestyle changes and working with your healthcare team can often manage the condition. If you have concerns, talk to your doctor – they can help you understand your risk.
Diagnosis
Doctors diagnose the blocked arteries that may need CABG by doing tests that check your heart and blood flow. They will also ask about your symptoms, medical history, and risk factors.
Tests that may be done
Electrocardiogram (ECG or EKG) – a quick test that records the electrical activity of your heart
Stress test – you exercise or take medicine while your heart is monitored
Echocardiogram – an ultrasound of your heart to see its structure and pumping function
Coronary angiography – a special X-ray where dye is injected into your heart arteries to see blockages
What to expect at your appointment
If your doctor thinks you might need CABG, you will see a heart specialist (cardiologist) and a heart surgeon. They will review your test results and talk with you about the best treatment. The surgery is planned in advance, and you’ll have time to ask questions and prepare.
Treatment
CABG is a major surgery that treats blocked heart arteries. It is done when medicines and less invasive procedures are not enough to control symptoms or reduce the risk of a heart attack. The surgery creates a detour around the blocked area using a healthy blood vessel from elsewhere in your body.
Self-care at home
Take all prescribed medicines exactly as directed by your doctor.
Quit smoking if you smoke – it is the single most important thing you can do for your heart.
Eat a heart-healthy diet low in salt, unhealthy fats, and added sugars.
Stay active as advised by your healthcare team after surgery.
Keep all follow-up appointments and attend cardiac rehabilitation if recommended.
Medical treatments
Before considering CABG, doctors often try medical treatments such as medicines to lower blood pressure, reduce cholesterol, prevent blood clots, and relieve chest pain. These medicines help manage symptoms and slow the progression of artery disease. Your doctor will choose the right combination for you based on your health.
When is surgery considered?
CABG is usually recommended when you have severe blockages in multiple heart arteries, especially the main left artery, or when your symptoms are not controlled with medicines. It is also done in emergency situations, like a heart attack, when blood flow to the heart needs to be restored quickly.
Living with this condition
Recovering from CABG takes time – most people stay in the hospital for about a week, then need several weeks of rest at home. You will feel tired and may have pain around the incision sites. It is important to follow your care team's instructions for wound care, activity limits, and medicines. Most people can return to normal activities within 6 to 12 weeks.
Lifestyle tips
Gradually increase physical activity as your doctor advises – start with short walks.
Join a cardiac rehabilitation program, which offers supervised exercise and education.
Manage stress through relaxation techniques, hobbies, or talking to a counselor.
Avoid heavy lifting or strenuous activities until your doctor says it is safe.
Diet and exercise
Eat plenty of fruits, vegetables, whole grains, lean protein (like fish or poultry), and healthy fats (like olive oil). Limit red meat, fried foods, and foods high in salt or sugar. Exercise is important after recovery – aim for moderate activity like brisk walking for 30 minutes most days, but check with your doctor first.
Mental health and emotional wellbeing
Heart surgery can be emotionally challenging. It is normal to feel anxious, sad, or overwhelmed during recovery. Talk to your healthcare team if you feel depressed or have trouble adjusting – they can connect you with support. Remember, taking care of your emotional health is just as important as your physical recovery.
Prevention
While not all heart disease can be prevented, you can lower your risk of needing CABG by managing your risk factors. This includes not smoking, eating a heart-healthy diet, staying active, controlling blood pressure and cholesterol, and managing diabetes. Even after CABG, these steps help prevent future blockages.
Vaccines
Vaccines do not directly prevent heart artery blockages. However, getting recommended vaccines (like the flu shot and pneumonia vaccine) can help prevent infections that might put extra strain on your heart. Ask your doctor which vaccines are right for you.
Screening programmes
Routine screening for high blood pressure, high cholesterol, and diabetes can catch problems early. If you have a family history of heart disease or other risk factors, your doctor may suggest earlier or more frequent screening.
Complications
If left untreated
If severe heart artery blockages are left untreated, they can lead to a heart attack (myocardial infarction).
Untreated blockages can also cause heart failure (when the heart cannot pump blood well enough), arrhythmias (irregular heartbeats), or sudden cardiac arrest.
Long-term outlook
CABG has been performed safely for many decades. Most people who have the surgery experience significant relief from chest pain and a better quality of life. The outlook depends on your overall health and how well you follow your treatment plan. With healthy habits and medical care, many people live well for years after CABG.
