Success rate of Coronary Artery Bypass Surgery

CABG is usually performed to revive the blood flow to a clogged up artery. This is mostly done in patients with angina or coronary artery disease. This generally involves taking a graft from a normal blood vessel and adding it to the damaged artery, reestablishing the blood flow to the heart.


There are numerous factors affecting the success rate of the surgery:

  1. Age of the patient- this is one of the most common factors. Younger patients are likely to recover faster than the elder patients. This is due to the fact that young people have better neuromuscular coordination than the older people. Also, the geriatrics tend to have more medical conditions affecting the success of the surgery.

  2. Diabetes- those having diabetes mellitus have high risk of infection during the surgery. This may lead to severe medical conditions like cellulitis. Moreover, the healing and recovery is delayed. However, this is taken care of by putting the patients on essential antibiotics and managing the glucose levels before the surgery.

  3. Hypertension- if patients with raised blood pressure undergo coronary artery bypass surgery, may have to face conditions like congestive heart failure or kidney issues. Therefore the patient is required to take anti-hypertensive medication before the surgery. Also, the anesthesia is administered in a limited amount and under controlled circumstances.


Fortunately, the mortality rates have fallen down abruptly in the recent decades due to availability of enhanced infrastructure of the hospitals. The success rate is as high as 95%. In rest of the cases, complications like high bleeding risk, chest infection, deep vein thrombosis, pulmonary embolism or stroke may occur. If needful precautionary measures are taken by the surgeon and post-surgical care is done such as taking all the medications, following up with doctor as advised; success rates are further multiplied.

Furthermore, the good news is that an additional procedure has been adopted which is known as “completion angiography”. This technique enables the surgeon to confirm the success of the surgery instantly by examining the blood flow in the graft vessel. This is only possible, where this a provision for both CABG and angiography. The topmost cardiology hospitals in India have all such facilities that uplift the success of the surgery. This is evident from the fact, how a patient with minimum cardiac efficiency visits India and gets CABG done successfully with the assistance of Vaidam
