Ten-Year Outcomes of Off-Pump vs On-Pump Coronary Artery Bypass Grafting in the Department of Veterans Affairs
This 10-year follow-up of the ROBY study reports on the primary end points of all-cause death and the composite of death or revascularization among 2203 patients randomized to off-pump or on-pump CABG 2002-2007. Death rates at 10 years were 34.2% for off-pump and 31.1% for on-pump. The composite end point was reached at 4.6 years for off-pump and 5.0 years for on-pump. The study identified no advantages for off-pump bypass related to these 10-year outcomes.
