摘要
Objectives:Meta-analysis was performed to evaluate the effect of staged revascularization with concomitant chronic total occlusion(CTO)in the non-infarct-associated artery(non-IRA)in patients with ST-segment elevation myocardial infarction(STEMI)treated with primary percutaneous coronary intervention(p-PCI).Methods:Various electronic databases were searched for studies published from inception to June,2021.The primary endpoint was all-cause death,and the secondary endpoint was a composite of major adverse cardiac events(MACEs).Odds ratios(ORs)were pooled with 95%confidence intervals(CIs)for dichotomous data.Results:Seven studies involving 1540 participants were included in thefinal analysis.Pooled analyses revealed that patients with successful staged revascularization for CTO in non-IRA with STEMI treated with p-PCI had overall lower all-cause death compared with the occluded CTO group(OR,0.46;95%CI,0.23–0.95),cardiac death(OR,0.43;95%CI,0.20–0.91),MACEs(OR,0.47;95%CI,0.32–0.69)and heart failure(OR,0.57;95%CI,0.37–0.89)com-pared with the occluded CTO group.No significant differences were observed between groups regarding myocardial infarction and repeated revascularization.Conclusions:Successful revascularization of CTO in the non-IRA was associated with better outcomes in patients with STEMI treated with p-PCI.
