A meta-analysis was performed to in- tegrate the results of independent studies to provide a more precise estimate of the treatment effect. Methods A systematic literature search was carried out for all the relevant articles up till March 2012. Only studies with adequate data reporting major adverse cardiac events （MACE） and target lesion revascularization （TLR）, and follow-up of at least 6 months were included. The endpoints analyzed in this meta-analysis were stent throm- bosis （ST）, all-cause death, myocardial infarction （MI）, MACE and TLR. Result Four studies were found to be eligible for inclusion in the meta-analysis. There were also no significant differences with the occurrence of MI （1.7% vs. 1.5%, OR 1.14, 95% CI 0.38 to 3.44, P = 0.81）, all-cause death （1.1% vs. 1.1%, P = 0.84, OR 0.91, 95% CI 0.35 to 2.35） and stent thrombosis （0.9% vs. 0.8%, OR 1.03, 95% CI 0.35 to 3.09, P = 0.95） in patients with FKBD or No FKBD. However, FKBD was associated with a higher risk of MACE （8.0% vs. 5.3%, OR 1.56, 95% CI, 1.02-2.39, P = 0.04）, primarily as a result of an increased risk of TLR （6.4% vs. 3.4%, OR 2.12, 95% CI 1.30 to 3.48 P = 0.003）. Conclusions In patients with coronary bifurca- tion lesions treated with 1-stent technique, FKBD may be associated with adverse outcomes mainly because of a higher rate of TLR.展开更多
