Abstract

Abstract: Background: Impact of SYNTAX score II (SSII) on long-term clinical outcomes after cobalt-chromium everolimus-eluting stent (CoCr-EES) implantation remains unclear. Methods: Between February 2010 and May 2011, 1064 consecutive patients with 1440 lesions were treated only with CoCr-EES implantation. Of these, the SSII was calculated in 1013 patients with 1345 lesions. Patients were divided into the tertile group: Tertiles for SSII (low SSII [12–28.9], n=334; intermediate SSII [29–39.1], n=339; and high SSII [39.2–80.8], n=340). We assessed the cumulative 7-year incidences of major adverse cardiac events (MACE), defined as a composite of cardiac death, myocardial infarction, definite stent thrombosis, and clinically driven target lesion revascularization (CDTLR) based on SSII groupings. Results: Cumulative 7-year incidence of MACE was significantly higher in the high SSII group than in the other groups (34.1% vs. 18.6% vs. 17.2%, p<0.001). The cumulative incidence of cardiac death, myocardial infarction and stent thrombosis were significantly higher in the high SSII group than in the other groups (22.1% vs. 2.0% vs. 5.3%, p<0.001; 6.6% vs. 4.9% vs. 1.7%, p=0.01; 2.9% vs. 1.7% vs. 0.3%, p=0.03, respectively). The cumulative incidence of CDTLR was similar between the groups (15.2% vs. 12.8% vs. 15.7%, p=0.57). High SSII group (hazard ratio [HR] 2.18 [vs. low SS], 95% confidence intervals [CI]: 1.56–3.06, p<0.001) and diabetes mellitus (HR 1.37, 95% CI: 1.04–1.81, p=0.03) were predictors of 7-year MACE. Conclusions: SSII has significantly impact on 7 years clinical outcomes after CoCr-EES implantation. Funding Acknowledgement: Type of funding source: None
