BACKGROUND: There is increasing evidence that various types of drug-eluting stents (DES) may differ regarding the long-term safety and efficacy, particularly in complex lesion subsets.
AIMS: In a cohort of consecutive patients undergoing bifurcation stenting, we sought to compare the 1-year efficacy and safety of the first-generation paclitaxel-eluting stents (PES), the first-generation sirolimus-eluting (SES) and the second-generation everolimus- or zotarolimus-eluting stents (EES/ZES).
METHODS: We treated 2197 patients (mean age 67.5 years, 75.4 % male) with provisional T-stenting for de novo coronary bifurcation lesions using PES, SES or EES/ZES. Primary endpoint (MACE) was the composite of death from any cause, myocardial infarction (MI) and target lesion revascularisation (TLR).
RESULTS: Side branch stenting was found to be clinically indicated in 793 patients (36.1 %). The cumulative 1-year incidence of MACE was 18.8 % after PES, 13.1 % after PCI with SES and 12.2 % after EES/ZES (p = 0.003), the combined endpoint death and MI occurred in 6.6, 5.6 and 8.3 % (p = 0.253) and death in 4.3, 5.2 and 5.3 % (p = 0.581), respectively. After adjustment for co-variables the type of DES was a significant (p = 0.008) predictor of MACE [HR (95 % confidence interval) PES vs SES 1.34 (1.04-1.71), PES vs. EES/ZES 1.75 (1.19-2.57), EES/ZES vs. SES 0.762 (0.531-1.095)], but not of death (p = 0.581), death and MI (p = 0.077) or stent thrombosis (ST) (p = 0.925).
CONCLUSIONS: In de novo coronary bifurcation lesions treated with provisional T-stenting, SES and EES/ZES achieved better outcomes than PES by reducing the need for reintervention.
