A Meta‐Analysis of ≥5‐Year Mortality in Randomized Controlled Trials of Off‐Pump Versus On‐Pump Coronary Artery Bypass Grafting

Takagi and colleagues performed a meta-analysis of eight randomized controlled trials comparing on-pump and off-pump coronary artery bypass grafting (CABG). They evaluated only trials with follow-up periods of five years or longer, and they pooled hazard ratios rather than odds ratios, where possible. The authors’ analysis found an increased mortality risk with off-pump CABG.
