Effect of coronary artery bypass graft surgery on survival

Fig 1: CABG

Coronary artery bypass grafting has been shown to improve survival in patients with left main stem stenosis (> 60%), triple vessel disease and impaired left ventricular function and triple vessel disease with proximal left anterior descending artery disease, when compared to medical therapy.

Angioplasty is exceedingly high risk and therefore is only contemplated when patients are deemed as non-operative candidates.
