coronary artery bypass grafting CABG overview NIH
CABG stands for coronary artery bypass grafting. It is open-heart surgery used to improve blood flow to the heart when one or more coronary arteries are severely narrowed or blocked by coronary artery disease.
A surgeon takes a healthy blood vessel, commonly:
- An artery from inside the chest, often the left internal mammary artery
- A vein from the leg, called the saphenous vein
- Sometimes an artery from the arm
The vessel is attached so that blood can travel around the blockage to reach the heart muscle. The blockage is usually left in place, rather than removed.
CABG may be recommended for severe disease in multiple coronary arteries, blockage of the left main coronary artery, diabetes with complex multivessel disease, or when angioplasty/stenting is not suitable. It can also be used urgently during certain heart attacks. The NHLBI overview describes CABG as using chest-wall arteries and leg veins to bypass blocked coronary arteries.
It can be performed:
- On-pump, using a heart-lung machine while the heart is temporarily stopped
- Off-pump, while the heart continues beating in selected patients
CABG improves blood supply and often relieves angina, but it does not cure atherosclerosis. Long-term treatment still includes medicines and risk-factor control, such as stopping smoking, controlling blood pressure, diabetes, and cholesterol. Potential complications include bleeding, infection, abnormal heart rhythm, stroke, heart attack, kidney injury, and graft narrowing over time.

CABG: coronary artery bypass grafting
CABG is an operation that restores blood flow to heart muscle beyond narrowed or blocked coronary arteries. It does not remove the plaque blockage. Instead, the surgeon creates a new route, or graft, for blood to reach the coronary artery below the blockage.
It is commonly called “bypass surgery” because the new vessel bypasses the diseased segment.
Coronary arteries originate from the aorta and run over the surface of the heart. CABG grafts are connected to targets beyond obstructed segments. Bailey and Love's Short Practice of Surgery, p. 968.
Why CABG is done
CABG may be selected when coronary artery disease is too extensive, complex, or high-risk for treatment with medicines or stents alone. Common reasons include:
- Significant left main coronary artery disease
- Severe three-vessel coronary artery disease
- Multivessel disease with diabetes
- Disease involving the proximal left anterior descending artery, or LAD
- Persistent angina despite optimal medication
- Failed or unsuitable PCI, meaning balloon angioplasty/stenting
- Some emergency situations, including ongoing ischemia or complications of a heart attack
The main goals are to relieve angina, improve exercise capacity and quality of life, prevent myocardial infarction in selected groups, and improve survival in certain high-risk coronary patterns. In people with left-main or complex multivessel disease, especially with reduced left-ventricular function, CABG may provide a survival advantage. Harrison’s Principles of Internal Medicine, 22e, p. 575-596.
Which vessels are used as grafts?
The graft is taken from a vessel that the body can generally function without, or from an artery whose remaining circulation is adequate.
| Conduit | Source | Typical use and advantage |
|---|---|---|
| Left internal mammary artery (LIMA), also called left internal thoracic artery | Inner chest wall | Usually connected to the LAD. It remains attached at its origin from the subclavian artery and has excellent long-term patency. |
| Right internal mammary artery (RIMA) | Inner right chest wall | May be used in selected patients for additional arterial grafting. |
| Radial artery | Forearm | Used as a free arterial graft after confirming that hand circulation will remain adequate. |
| Great saphenous vein | Leg | Commonly used for additional bypasses. One end is attached to the aorta and the other to a coronary artery beyond the obstruction. |
Arterial grafts, particularly the internal mammary artery to the LAD, generally remain open longer than saphenous-vein grafts. Harrison’s Principles of Internal Medicine, 22e, p. 577-588.
The principle of the operation
For a vein graft, the configuration is usually:
Aorta → saphenous vein graft → coronary artery distal to the blockage
For a LIMA graft, the artery usually stays connected to its natural origin, so the configuration is:
Left subclavian artery → LIMA → LAD distal to the blockage
The connection of a graft to a coronary artery is called the distal anastomosis. A vein graft connection to the aorta is the proximal anastomosis.
A patient may receive one, two, three, or more grafts. The terms “double,” “triple,” or “quadruple bypass” refer to the number of coronary targets grafted, not necessarily the number of harvested vessels.
How CABG is performed
This is a highly specialized operation done by a cardiac-surgery team with cardiac anesthesia, perfusion staff, ICU support, and continuous monitoring. The outline below is educational, not a guide for attempting surgery.
1. Preoperative planning
Before surgery, the team reviews:
- Coronary angiography to identify each blockage and suitable distal coronary target
- Echocardiography to assess heart pumping function and valves
- Kidney function, blood count, diabetes control, lung disease, carotid and peripheral arterial disease
- Current antiplatelet and anticoagulant medicines
- Availability and quality of possible graft conduits
The surgeon decides which arteries need revascularization and selects the graft plan. The LAD is frequently grafted because it supplies a large amount of heart muscle and is commonly affected by disease. Bailey and Love's Short Practice of Surgery, p. 968.
2. Anesthesia, monitoring, and preparation
The patient receives general anesthesia and is intubated. The surgical team inserts invasive monitoring lines, typically including:
- An arterial line for beat-to-beat blood-pressure monitoring
- Central venous access
- A urinary catheter
- Transesophageal echocardiography in many cases, which images cardiac function during surgery
The chest, and usually the leg and/or arm, are cleaned and draped because grafts may be harvested from these sites.
3. Surgical access and graft harvesting
Traditional CABG
Most conventional CABG procedures use a median sternotomy:
- A midline chest incision is made.
- The breastbone, or sternum, is divided vertically.
- A sternal retractor opens the chest so the heart can be accessed.
At the same time, another member of the surgical team may harvest the saphenous vein from the leg, often through smaller endoscopic incisions. The internal mammary artery is carefully mobilized from the inside chest wall. The radial artery may be harvested from the forearm when selected.
4. On-pump CABG: the most common conventional approach
In traditional on-pump CABG, a cardiopulmonary bypass machine, also called a heart-lung machine, temporarily performs the heart’s pumping and lung oxygenation functions.
The broad sequence is:
- Heparin anticoagulation is administered to prevent blood clotting in the bypass circuit.
- Large cannulas are placed in the heart and major vessels.
- Blood is diverted to the heart-lung machine, where it is oxygenated and pumped back to the body.
- The aorta is temporarily clamped.
- Cardioplegia, a cold protective solution, is delivered to stop the heart in a controlled way and reduce its metabolic demand.
- The surgeon sews the grafts to coronary arteries beyond the blockages.
- Vein grafts or free arterial grafts are connected proximally to the aorta when required.
- The aortic clamp is removed and the heart is restarted, sometimes with pacing or medications.
- The patient is gradually separated from the bypass machine after the team confirms stable heart function and blood pressure.
- Heparin is reversed, bleeding is controlled, chest drains are placed, and the sternum is closed with wires.
Cardioplegic arrest provides a still, bloodless operative field for precise coronary graft connections. Potential cardiopulmonary-bypass complications include coagulation disturbance, inflammatory response, embolic events, neurologic dysfunction, and organ dysfunction. Bailey and Love's Short Practice of Surgery, p. 968.
5. Off-pump CABG: beating-heart surgery
Off-pump CABG, or OPCAB, avoids the heart-lung machine. The heart continues beating.
The surgeon uses mechanical stabilizing devices to hold a small area of the moving heart relatively still while the coronary connection is created. The target coronary artery may be temporarily controlled to limit bleeding, and a small intraluminal shunt may be used in some cases to preserve distal coronary flow.
Potential benefits in selected patients include avoiding some effects of cardiopulmonary bypass. However, exposure can be technically demanding because moving or lifting the heart to reach lateral or posterior coronary arteries can reduce blood pressure and cardiac filling. It is therefore chosen selectively, based on the patient’s anatomy, risk profile, and the surgical team’s expertise. Miller’s Anesthesia, 10e, pp. 7594-7596.
6. Minimally invasive and hybrid CABG
Some selected patients can have CABG through a smaller incision between the ribs rather than full sternotomy, often to graft the LIMA to the LAD. Robotic and totally endoscopic methods are also available in specialized centers.
A hybrid strategy may combine a surgical LIMA-to-LAD graft with stenting of other coronary arteries. These options are not suitable for every coronary anatomy.
What happens immediately after surgery?
The patient goes to a cardiac ICU, usually with:
- A breathing tube and ventilator temporarily, often removed within about 24 hours if stable
- Chest tubes to drain blood and fluid
- Temporary pacing wires in some cases
- Continuous ECG, oxygen, blood-pressure, urine-output, and laboratory monitoring
- Pain relief, early breathing exercises, and early mobilization
Common early issues include pain, temporary fluid retention, anemia, irregular rhythm, especially atrial fibrillation, and fatigue. Major complications can include bleeding requiring transfusion or reoperation, stroke, heart attack, kidney injury, infection including sternal wound infection, respiratory complications, graft failure, and death. Individual risk depends heavily on age, heart function, kidney and lung disease, diabetes, urgency of surgery, and overall frailty.
Recovery
Typical recovery after conventional CABG involves about one week in hospital followed by roughly 6 to 12 weeks of recovery at home. Cardiac rehabilitation, gradual walking and activity progression, wound care, and adherence to medicines are central to recovery. The NHLBI recovery guidance describes this expected timeframe and the role of continued follow-up.
CABG does not cure atherosclerosis. Long-term graft and heart protection usually includes:
- Antiplatelet treatment, commonly aspirin
- High-intensity statin therapy when appropriate
- Blood-pressure and diabetes control
- Smoking cessation
- Cardiac rehabilitation and regular exercise
- A heart-healthy dietary pattern
- Long-term follow-up for recurrent symptoms or graft disease
Recent evidence supports CABG as an important strategy in appropriate stable coronary disease, but treatment choices should be individualized by a cardiologist and cardiac surgeon. A recent pooled meta-analysis of randomized trials compared CABG with medical therapy in stable coronary artery disease (PMID 35821087).
