Abstract：Objective To evaluate the long - term clinical effect of percutaneous coronary intervention (PCI) in the treatment of coronary artery bifurcation with simple and complex strategies.Methods The databases of PubMed, Embase, the Cochrane Library and CNKI until July 2017 were retrieved for collecting the randomized controlled trials (RCTs) comparing PCI simple strategy with complex strategy for bifurcation lesions. The Meta-analysis was performed using Stata 12.0 software.Results 4 RCTs with a total of 1455 patients reported clinical outcomes of 5 years follow-up. The result of Meta-analysis showed that there was no significant difference with respect of all cause death (RR=1.50, 95％CI: 0.98～2.29,P=0.065), major adverse cardiac event (RR=0.97, 95％CI:0.62～1.51,P=0.889), cardiac death (RR=1.09, 95％CI: 0.49～2.44,P=0.832), myocardial infarction (RR=1.69, 95％CI: 0.92～3.09,P=0.090), target lesion revascularization (RR=0.92, 95％CI: 0.53～1.61,P=0.774) and stent thrombosis (RR=1.00, 95％CI: 0.47～2.14,P=1.000) between two strategies.Conclusion Complex strategy for treating patients with bifurcation lesions didn't increase adverse events rate in long-term. Complex strategy may be an optimal method for the patients with ACS or truth bifurcation lesions.
