Abstract:

Aim: was to evaluate the safety and efficacy of coronary stents «MedEng» and to compare them with results of the use of other coronary stents.

Materials and methods: the study included 147 patients with coronary artery disease, which in the period from January to March 2014 underwent coronary stenting. Stents «MedEng» were implanted in 61 patients (group 1). The second group (control) consisted of 86 patients who underwent implantation of stents «Driver». Average follow-up was 6,2±0,5 months. Endpoints were: the return or retention of not less than 2 angina functional class (on CCS); death by cardiac causes, myocardial infarction (MI), repeated intervention on the target vessel, restenosis> 50%, confirmed by angiography and/or the data of optical coherence tomography (OCT)

Results: success rate of stenting was 100%. Death and MI during follow-up were not observed. Restenosis was observed in 9(14,7%) patients in group «MedEng» and in 13 (15,1%) patients from «Driver» group (p = 0,9). The average degree of coronary restenosis was 76,1±8,4% and 76,2±6,4% in the first and second groups, respectively (p=0.9). According to results of logistic regression, stents «MedEng» was not a predictor of restenosis (OR=1,998; 95% CI (0,158-312,551); p = 0,314).

Conclusions: the use of stents «MedEng» is safe and effective in myocardial revascularization. Results of implantation of stents «MedEng» do not different from results of the use of stents «Driver».
