Better Long-Term Survival with On-Pump vs. Off-Pump CABG

Overall mortality risk was 50% higher in patients who underwent off-pump versus on-pump coronary artery bypass grafting.

Compared with on-pump coronary artery bypass grafting (CABG), off-pump surgery offers potential advantages of reduced bleeding, reduced need for transfusion, and superior neurocognitive outcomes. However, few studies have compared long-term survival with each strategy.

In the current study, investigators compared all-cause mortality in 2333 patients who underwent off-pump CABG and 2570 patients who underwent on-pump surgery between 1989 and 2012 at a single center in Korea. Compared with the on-pump group, rates of diabetes, hypertension, and single-vessel coronary artery disease (CAD) were higher in the off-pump group. Mean ejection fraction was also slightly higher in the off-pump group, but age, sex, and prevalence of left-main CAD were s…
