However, no consistent results were obtained. In the present study, a meta-analysis was conducted by searching the electronic databases Pub Med, Embase, Web of Science, and Cochrane to identify the association of post-CABG AF with on-pump（conventional CABG, c CABG） or off-pump CABG（OPCABG）. Outcomes from randomized clinical trials（RCTs） and propensity score matching（PSM） trials were pooled by using the fixed-effect or the random-effect modeling method, and verified by the quality-effect modeling method. There were 35 studies with 36 independent reports that met the inclusion criteria and were eventually included in our meta-analysis. The total odds ratio（OR） of the incidence of post-CABG AF between OPCABG and c CABG was 0.80（95% CI 0.71–0.91）. The 25 randomized clinical trials（RCTs） had an OR of 0.69（95% CI 0.56–0.86）, while the OR of the 11 PSM trials was 0.88（95% CI 0.77–1.00）. Twenty-six studies involving the patients at a mean age no more than 65 years showed an OR of 0.76（95% CI 0.64–0.90）, whereas 10 studies with patients greater than 65 years old showed an OR of 0.90（95% CI 0.78–1.05）. The results of this meta-analysis suggest that OPCAB surgery may reduce the incidence of post-CABG AF when compared to c CABG and that younger patients may benefit more from OPCAB and have a lower incidence of post-CABG AF.展开更多
