BACKGROUND: Despite the efficacy of first generation drug eluting stents in reducing the need of new interventions, its use in more complex conditions, such as acute coronary syndromes, may be associated to higher thrombosis rates. Pre-clinical analyses have attributed a major role to durable polymers in the genesis of these adverse events. The SupralimusTM stent combines a stainless steel platform with a bioabsorbable polymer loaded with sirolimus. This study was aimed at establishing the safety and clinical efficacy of this new drug eluting stent in non-selected acute coronary syndrome patients. METHOD: The E-SERIES Registry is a multicenter and prospective study, including consecutive patients treated with SupralimusTM stent. Virtually all subtypes of patients and lesions are represented in this registry. Information regarding the procedure and clinical outcomes is collected through the internet and adverse events are adjudicated by an independent committee. RESULTS: A total of 1,263 patients were included and 454 (35.9%) had an initial diagnosis of acute coronary syndrome. Most patients were male (68.9%) with mean age of 63 ± 11.4 years. Diabetes mellitus was highly prevalent in this subset (36.8%). Thrombus was visible at pre-intervention angiography in 6% of the cases. Final TIMI 3 flow was achieved in 96.8% of the patients. In-hospital major adverse cardiac events rate was 1% (mortality of 0.4%). Six-month cumulative major adverse cardiac events rate was 10% with 0.4% of stent thrombosis. CONCLUSIONS: The use of SupralimusTM drug eluting stent in the treatment of complex patients with acute coronary syndromes demonstrated excellent performance and safety profile in the midterm follow-up, with low adverse events and thrombosis rates.
