DISTANT CLINICAL RESULTS OF BALLOON CORONARY ANGIOPLASTY IN PATIENTS SUFFERING FROM ISCHEMIC HEART DISEASE WITH DOUBLE-VASCULAR AFFECTION OF BLOODSTREAM

The aim of the study - to observe distant clinical effectiveness of balloon coronary angioplasty (BCA) in patients with double-vascular affection of bloodstream depending on completeness of myocardial revascularization. 69 patients with ischemic heart disease and with initially clinically successful performed double-vascular affection of bloodstream were included in the study. Preservation of achieved clinical success in time from 6 to 12 months after performed BCA as initial clinical success was kept in mind. Distant clinical effectiveness of BCA averaged 56,6 % (39 of 69 patients). The percentage of favourable clinical results in patients with achieved complete anatomical myocardial revascularization averaged 55,2 % (16 from 29 patients), with incomplete adequate functional anatomical revascularization averaged 54,8 % (17 from 31 patients), with incomplete anatomical revascularization (BCA of symptom connected artery (SCA)) averaged 66,7 % (6 from 9 patients). In overwhelming majority of cases restenosis of reconstruction segments was the reason of clinical condition impairment. During the stent implantation distant clinical results were slightly better independently of extent of achieved revascularization. Distant clinical results of BCA in patients with double-vascular affection of bloodstream straight depend on quantity of arteries subjected to angioplasty. Under one year observation the achievement of complete anatomical revascularization reduce the clinical effectiveness. In distant period stent implantation slightly improves clinical results of double-vascular BCA due to reduction of percentage of restenosis. Incomplete anatomical revascularization improve clinical results of BCA at impairment of two coronary arteries, therefore during selection of surgical intervention capacity is more advisable to prefer BCA.
