3 Rationale for the registry The experience with first generation DES (Cypher® and Taxus ®) showed that randomized trials do not reflect the risk for late thrombosis associated with their use in real practice (frequent off-label usage,...). Industry-independent, large-scale registries without exclusion criteria yielded a linearly growing rate of thrombosis with % per year. Second generation DES (Endeavor ®, Xience ® and Promus ®) based in new platforms, polymers and drugs (Zotarolimus and Everolimus), have shown to be safe and effective in randomized trials but, Again, we need registries from real practice to ascertain the risk for late thrombosis with these new DES according to current definitions.

4 Methods 34 centers throughout Spain (public tertiary hospitals) Data Collection: Web-based CRF (supported by the Spanish Working Group on Interventional Cardiology) Detailed forms (clinical and procedural) for all patients treated with Everolimus-eluting stents (EES) or Zotarolimus-eluting stents (ZES) until April / 08. Systematic clinical follow up of all patients in: May 2008 May 2009 Detailed forms for all cases with definite, probable or possible stent thrombosis. Adjudication process by independent-one person MD event review According to confidential regulations in Spain.

21 In this registry the incidence at 1 year of definite + probable stent thrombosis was 1.4% for everolimus-eluting stents and 1.5% for zotarolimus-eluting stents. This incidence results slightly lower compared to the reported with 1 st generation DES (1 yr definite thrombosis % (1-5) vs 1%) This could be attributable to a combined effect of: drug-eluting stent, better case selection, improved implantation technique and higher antiplatelet therapy adherence No significant differences were found between EES and ZES. Ejection fraction, hypertension and stent diameter were independent predictors for thrombosis. Stent use in myocardial infarction was not associated with a higher incidence of thrombosis. A longer follow up is needed to determine the incidence of thrombosis over following years. Conclusions 1 Colombo A et al. JAMA 2005;293: Daemen J et al. Lancet 2007;369: Ong A et al.
