Stenting — it is a widespread procedure for patients that are suffering from coronary artery disease. Possibility to use drugs-covered stents, improved stenting safety and treatment efficiency. Using second generation Biolimus drugs-covered Stents A9 is associated reduced risk of stent thrombosis copaired with rst generation. However the possibility of stent thrombosis and restenosis as late complication still persist. In this survey we tried to evaluate 2 years treatment results after Biolimus A9 stents implantation in coronary arteries.
The retrospective study performed in LSMUL KK Cardiology department. There was 216 patients suffered from coronary artery disease, and were treated using Biolimus A9 drugs-covered stents, in this way eliminating all bigger than 50 % stenosis. Data collected from hospital case histories and e-Biomatrix PMR questionnaire. The rate of complication after stenting were evaluated, when stenosis were eliminated or reduced to 30% or TIMI 3 ow were determined. We evaluated the rate of complications( myocardial infarction, Stent thrombosis, the need of revascularization, stroke, death) in 2 years period. Data was analyzed using SPSS v. 22.0 programme. Categorical variables were summarized as frequencies with percentages and were compared using Chi-square test or Fisher's exact test. Survival curves were constructed using Kaplan-Meier estimates and were compared using log-rank test.
There were 216 patients in a survey, 69.91% men and 30.09% women. The age mean was 60.17 ± 10.13 years. Diabetes was diagnosed for 19% of patients. The success of Biolimus A9 implantation was 110%. The rate of complications after stenting was 0.93% (2 cases) There were no complication in hospital. There rate of complication during one year period was 1.4% (1 stent thrombosis, 2 new revascularizations, 1 stroke). There rate of complication during second year period was 0.46% (1 revascularization).
The implantation of Biolimus a9 stent is safe and effective procedure, with low-risk for complications. There was no complications in hospital. The rate of complications during 2 year period is low.
