RESUMO
OBJECTIVES: We sought to evaluate clinical outcomes in patients treated with the drug-eluting stent ihtDEStiny BD. BACKGROUND: The ihtDEStiny BD stent is a metallic sirolimus eluting stent with a biodegradable polymer with both drug and polymer coating the abluminal surface of the stent and balloon. METHODS: In this study, the clinical outcomes of a multicenter prospective registry of patients treated with this stent (DEStiny group) were analyzed and compared with those of a control group of patients treated with durable polymer everolimus or zotarolimus eluting stents (CONTROL group) paired by propensity score matching. Primary outcome was the target vessel failure (TVF) at 12â¯months defined as a composite of cardiac death, target vessel myocardial infarction (TV-MI) and target vessel revascularization (TVR). RESULTS: A total of 350 patients were included in the DESTtiny group. The control group consisted initially of 1368 patients, but after matching (1:1) 350 patients were selected as CONTROL group. The baseline clinical, angiographic and procedural characteristics were quite comparable in both groups. At 12â¯months follow up the TVF was 6.6% in DEStiny group and 6.3% in CONTROL group (pâ¯=â¯0.8). No differences were observed for any of the individual components of the primary endpoint: cardiac death 1.1% vs. 1.4%, TV-MI 3.4% vs. 3.7% and TVR 2.6% vs. 2.3% respectively. CONCLUSIONS: The use of ihtDEStiny stent in real practice is associated with a clinical performance at 12â¯months follow up that appears to be non-inferior to the most widely used and largely evidence supported durable polymer drug eluting stents. A longer follow up is warranted.
