| Sumario: | ABSTRACT Introduction and objectives: After the positive pre-clinical and clinical results with Angiolite, a cobalt-chromium sirolimus-eluting stent, we decided to analyze its performance in a non-selected, real-world population: the RANGO registry. Methods: We conducted an observational, prospective, multicenter registry of patients with different clinical indications. All consecutive patients treated with percutaneous coronary intervention with, at least, 1 Angiolite stent and who gave their informed consent were included. The registry primary endpoint was the occurrence of target lesion failure (TLF) at 6, 12, and 24 months defined as cardiovascular death, myocardial infarction (MI) related to target vessel, and clinically driven target lesion revascularization. The secondary endpoints were the individual components of the primary endpoint, major adverse cardiovascular events (MACE: all-cause mortality, any MI, or any revascularization), and stent thrombosis. We describe the 2-year clinical results of the RANGO study in the entire population, in those who only received Angiolite stents, and in 2 predefined subgroups: diabetics and patients with small-vessels (≤ 2.5mm). Results: 646 patients (426 of them only received Angiolite stents) with a high-risk profile were recruited: prevalence of previous MI (18.4%), previous coronary revascularization (23.4%), clinical presentation as ST-segment elevation MI (23.1%), and multivessel disease (47.8%). At the 2-year follow-up, the rates of TLF, MACE, and stent thrombosis were 3.4%, 9.6%, and 0.9%, respectively. Similar results were observed among patients treated with Angiolite stents only: TLF, 3.1%; MACE, 8.0%; thrombosis, 0.7%. The rates were not significantly different for the diabetic (TLF, 3.0%; MACE, 14.1%; thrombosis, 1.0%), and small-vessel subgroups (TLF, 4.3%; MACE, 12.1%; thrombosis, 0%). Conclusions: In conclusion, the results of this observational registry on the use of Angiolite in a real-world population, including a high-risk population, corroborate the excellent results observed in previous studies, up to a 2-year follow-up. An extended 5-year follow-up is planned to discard the occurrence of late events. |
