CABG (Coronary Artery Bypass Grafting): Procedure, Benefits, Risks, and Recovery After Heart Surgery

Oleh: dr. Sugisman, Sp.BTKV (K)

What is CABG?

CABG is an open-heart surgical procedure that creates a “bypass” for blood flow bypassing a blocked or narrowed coronary artery, using a graft from a healthy blood vessel such as the saphenous vein, internal thoracic artery, or radial artery.

Why is CABG Necessary?

CABG recommendations are given to patients with:

• Severe blockage of the coronary arteries (>70%)
• Recurrent heart attacks
• Failed non-surgical therapy (such as angioplasty/stenting)
• Impaired heart pump function due to insufficient blood supply

How is the CABG Procedure Performed?

1. General anesthesia and a sternal incision to access the heart.
2. A heart-lung machine is used when the heart stops (conventional method), or is performed off-pump without stopping the heart.
3. Harvesting a graft from a vein or artery, then reattaching it around the blockage.
4. Suturing the graft, closing the wound, and monitoring in the ICU.

Post-operative Recovery and Care Period

• Hospitalization: typically 5–7 days in the hospital; some sources say up to a week.
• Full recovery: generally 6–12 weeks, with the initial, most critical phase lasting 6–8 weeks.
• Cardiac rehabilitation: begin in the hospital, progress to a structured program and light exercises at home.
• Wound care: keep the incision area clean and dry; watch for signs of infection such as redness, pus, or fever.

Benefits and Advantages

• Reduces angina and improves oxygen supply to the heart muscle.
• Improves life expectancy and quality of life, especially in patients with multiple blockages or major artery disease.
• More effective long-term than PCI in complex cases or multiple vessel disease.

Risks and Complications

Potential complications include wound infection, bleeding, stroke, heart rhythm disturbances, kidney failure, and others.

Preparation Before Surgery

• Pre-operative examinations: EKG, echocardiography, angiography, pulmonary function tests, blood tests, etc.
• Discontinuation of anticoagulant medications as directed by the doctor.
• Mental and physical preparation: smoking cessation, healthy diet, family support.

Conclusion

CABG is a major but highly effective surgery for patients with complex coronary artery disease. This procedure successfully creates a new blood supply to the heart, reducing angina, preventing heart attacks, and increasing life expectancy. The recovery process includes a short hospital stay, cardiac rehabilitation, and lifestyle changes. Before and after surgery, close medical monitoring is crucial for long-term success.
