ABSTRACT
Introduction. Drug-eluting stents have expanded their utility to more complex clinical and angiographic situations than the initial ones. Objective. To assess the effectiveness of Active and Active Small paclitaxel eluting stent models (Iberhospitex, Barcelona, Spain), in diabetic patients versus identical bare metal stents. Method. Prospective randomized study (2007-2015) at CIMEQ, Havana, Cuba, in 92 diabetic patients followed for three years, who agreed to participate, 48 with paclitaxel eluting stents (PES) and 44 with bare metal stents (SMC). Death, myocardial infarction, new target lesion revascularization and their combination, restenosis and stent thrombosis were considered. Frequency distribution, χ2 test, Fisher's test and T-Test of difference between means, Kaplan-Meier curve and Logarithmic Range Test (Mantel-Cox) were used, with statistical significance (α <0.05). That Research in line with the Helsinki declaration, approved by the local Scientific Council and the researchers without has conflict of interest to declare. Results. Myocardial Infarction during follow-up: SLP (0 )vs. SMC (4.5%), death 4.2% vs. 4.5%, new target lesion revascularization due to restenosis 14.6% vs. 34.1%, and late or very late thrombosis 2.1% vs 4.5%. There were 27 combined major cardiac adverse events, with a significant difference between the SLP group and the SMC group, 18.8% vs. 40.9%, respectively; p = 0.03). Conclusions. Paclitaxel eluting stents are more effective than conventional stents in diabetic patients because they reduce restenosis and major cardiac adverse events combined, with a similar incidence of death, myocardial infarction, and stent thrombosis after 3 years of follow-up.REFERENCES
