Experiencia con el uso del stent bioactivo cubierto con titanio-óxido nítrico comparado con stent liberador de zotarolimus: experiencia de una unidad médica de alta especialidad

Abstract

The use of coronary stents in coronary angioplasty has evolved dramatically in its design, type materials, polymers, and a variety of drugs, the use of coronary stents covered nitric oxide have shown satisfactory results in practice, however compared to the results reported drug-eluting stents, there is little information. The aim of this study was to compare clinical outcomes of a stainless steel stent Bioactive nitric oxide coated titanium (BAS) and a drug-eluting stent zotarolimus (DES) in daily clinical practice. A retrospective, analytical, descriptive and comparative study aimed at evaluating the safety and efficacy of two devices with different characteristics in our population. The primary endpoints were: death, acute infarction (AMI), and re intervention injury Treated (RLT). A total of 759 patients were included in the study which was performed angioplasty to a single vessel. Were divided into two arms 382 with DES and 377 patients with BAS, the one year follow up was carried in 95%. After this follow-up period, primary points (cardiovascular death, myocardial infarction, TLR and stent thrombosis) for arm DES vs BAS; 9.5% vs 8.5% P=NS but with shorter periods of dual antiplatelet therapy for arm BAS 6.9±4.1 vs 11.1±2.5 months DES P=.0001. The results were independent of the clinical syndrome of presentation. After one year of follow no statistically significant difference in major clinical events, there was a trend in favour of BAS vs SM with respect to revascularization of the target lesion without reaching statistical significance.
