### Question: Is off-pump coronary artery bypass grafting superior to drug-eluting stents for the treatment of coronary artery disease?

### Context: 1: As drug-eluting stent (DES) has almost overcome the disadvantage of frequent restenosis, off-pump coronary artery bypass grafting (OPCAB) has been introduced to avoid complications of cardiopulmonary bypass. However, which approach may promise better outcomes for patients with coronary artery disease remains controversial.
2: Three databases were searched. The outcomes of interest were major adverse cardiac and cerebrovascular events (MACCE), all-cause death, target vessel revascularization (TVR), repeat revascularization (RRV), myocardial infarction (MI), and cerebrovascular events (CVE). The relative risk (RR) was calculated as the summary statistic.
3: 11,452 patients from 22 studies were included, of which 4949 patients underwent OPCAB and 6503 patients received DES. The cumulative rates of MACCE (RR [95% CI]=0.43 [0.34, 0.54], P<0.00001), all-cause death (RR [95% CI]=0.56 [0.33, 0.96], P=0.03), TVR (RR [95% CI]=0.33 [0.21, 0.53], P<0.00001), RRV (RR [95% CI]=0.22 [0.11, 0.42], P<0.00001) and MI (RR [95% CI]=0.13 [0.05, 0.29], P<0.00001) at 3 years were all lower in OPCAB group. The incidences of in-hospital death (RR [95% CI]=1.31 [0.81, 2.13], P=0.27) and MI (RR [95% CI]=1.03 [0.60, 1.78], P=0.92) were not different between groups, but the rate of in-hospital CVE was lower (RR [95% CI]=2.6355 [1.0033, 6.9228], P=0.05) in DES group.


###Response: OPCAB presents better long-term outcomes of MACCE, all-cause mortality, TVR, RRV and MI but uncertain outcome of postoperative CVE without influencing the incidences of in-hospital death and MI.
