RESULTS OF 6 MONTHS FOLLOW-UP OF PATIENTS WITH ISCHEMIC-HEART-DISEASEAFTER TRANSLUMINAL BALLOON CORONARY ANGIOPLASTY

Clinical efficacy of transluminal balloon coronary angioplasty was eva luated In 71 patients with Ischemic heart disease. By the end of 6 mon ths of follow up 29 patients (41%) had no symptoms of ischemic heart d isease, in 22 patients (31%) clinical class of angina was improved and In 4 (6%) there were no changes compared to preangioplasty period. Cl inical state of 16 (22%) patients deteriorated 1 had myocardial infarc tion, 5(7%) underwent coronary artery bypass surgery, and In 10 (14%) repeat transluminal balloon coronary angioplasty was performed because of restenosis. Results of repetitive exercise tests (veloergometry) s howed that increase In tolerance to exercise achieved by angioplasty p ersisted throughout the period of follow-up. More pronounced favorable clinical effect was observed in patients without angiographic signs o f restenosis.
