Prognosis Following CABG

Prognosis following CABG depends on a variety of factors. Saphenous vein grafts remain open (patent) for approximately 8-15 years. In general, CABG improves the chances of survival of patients who are at high risk, such as those patients with left main disease. After approximately 5 years the difference in survival rate between those who have had surgery and those treated by drug therapy diminishes. Age at the time of CABG is critical to the prognosis, younger patients with no complicating diseases have a high probability of greater longevity. In a cohort of 1,388 patients who were 48.9 years at the time of their first surgery (young by today's standards) survival was as follows:[3]

5 years: 93.6%

10 years: 81.1%

15 years: 62.1%

20 years: 46.7%

23 years: 38.4%
