Introduction: The purpose of this study was to evaluate the angiographcally and periprocedural stent implantations restenosis risk factors in the patients after bar metal stent (BMS) implantation. Materials and methods: The study group consists of 59 patients, aged 37-87 (mean age 60.6) with in-stent restenosis (ISR) after BMS implantation treated with the aid of DES implantation and the control group consists of 39 patients, aged 40-80 (mean age 60) with ISR after BMS implantation treated plain old balloon angioplasty (POBA). In each patient with ISR coronary angiography results and technical aspects of BMS implantation were analyzed. Results: The expanded alteration in 69.5% of study group patients and 53.8% of control group patients referred to proximal section of coronary artery, in 49.1% and 46.1% LAD was subjected to expansion. In the study group 61% of patients and in control group 46.2% of patients underwent BMS implantation with “direct stenting” method, that is without prior balloon predilatation (NS). BMS implanted in the study group was shorter than BMS in the control group (18.9 vs. 24.3 mm; p=0.030). MACE was manifested in 5.1% of patients in both groups. Good direct procedure effect was achieved in patients of the examined group (100%) and 97.5% of the control group (NS). Conclusions: 1. In -bare metal stent restenosis was most often observed when was implanted in the proximal section of LAD. 2. In -bare metal stent restenosis was most often observed when stent length exceeded 10 mm.
