Five-year outcomes of on-pump vs off-pump CABG

Editor's Note

In this multicenter study, on-pump coronary artery bypass grafting (CABG) led to significantly higher rates of 5-year survival and event-free survival than off-pump CABG.

From 2002 to 2007, a total of 2,203 patients at 18 medical centers were randomly assigned to undergo either on-pump (1,099 patients) or off- pump (1,104 patients) CABG.

The mortality rate at 5 years was 11.9% in the on-pump group and 15.2% in the off-pump group.

The rate of major adverse cardiovascular events at 5 years was 27.1% in the on-pump group and 31.0% in the off-pump group.

Additional long-term follow-up, evaluating these same outcomes at 10 years is warranted, the researchers say.
