Abstract: Background: The potential for the CATANIA (CAT) stent to be an alternative to both bare-metal stents (BMS) and drug-eluting stents (DES) has been recently demonstrated in the Assessment of The LAtest Non-Thrombogenic Angioplasty stent (ATLANTA) first-in-human study. The aim of the present study was to compare short-term outcomes of patients treated with the CAT stent with those treated with BMS. Methods: Based on an internal registry, the 30-day and 6-month risk-adjusted outcomes for patients who received the CAT stent (n=254) were compared against outcomes of a historical cohort of patients who received BMS (n=552) between January 2001 and December 2001. Results: At 30 days, use of BMS vs. the CAT stent resulted in borderline significant differences with respect to major adverse cardiac and cerebrovascular events (MACCE) and cardiac death or myocardial infarction. At 6 months, BMS showed a statistically significant higher adjusted risk of MACCE (HR 2.79, 95% CIs 1.20–6.48, P=.017) and no differences with respect to the subcomponent end points. The cumulative incidence of definite stent thrombosis (Academic Research Consortium defined) at 6 months was 0.39% for the CAT stent and 2.35% for the BMS. Conclusions: This study confirms the favorable early and mid-term safety profile and the high-level efficacy of the CAT stent in the treatment of de novo coronary lesions seen in the ATLANTA trial. The use of stents with a nanothin Polyzene-F surface treatment provided improved results with respect to BMS and lower risk of acute and subacute stent thrombosis. [Copyright &y& Elsevier]
