Three-year major clinical outcomes of phosphorylcholine polymer- vs biolinx polymer-zotarolimus-eluting stents A propensity score matching study
- Abstract
- There are limited long-term outcome data comparing BioLinx polymer (B)-zotarolimus-eluting stents (ZES) with phosphorylcholine polymer (P)-ZES. The aim of this study was to compare the efficacy and safety of B-ZES with P-ZES in patients who underwent percutaneous coronary intervention (PCI) during a 3-year follow-up period. One thousand two hundred fifty four patients who underwent PCI with P-ZES (Endeavor [ZES-E] or Endeavor sprint [ZES-S], n=356) or B-ZES (Endeavor resolute [ZES-R] or Resolute Integrity [ZES-I], n=889) were enrolled. The primary endpoint was major adverse cardiac events (MACE); the composite of total death, non-fatal myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), non-target vessel revascularization (Non-TVR), and the secondary endpoint was stent thrombosis (ST). After PSM, 2 propensity-matched (PSM) groups (275 pairs, n=550, C-statistic=0.730) were generated. During the 3-year followup period, the cumulative incidence of MACE (hazard ratio [HR], 1.525; 95% confidence interval [CI], 0.920-2.526; P=.101) and ST (HR, 1.248; 95% CI, 0.335-4.4649; P=.741) were similar between P-ZES and B-ZES after PSM. However, TLR rate was significantly higher in ZES-S than ZES-I (11.3% vs 3.8%, log rank P=.029) and TVR rate was higher in ZES-S than ZES-R (14.1% vs 4.8%, log rank P=.025). In this single-center, all-comer registry, despite different polymers, P-ZES, and B-ZES showed comparable safety and efficacy during a 3-year follow-up period after PCI.
