[Early clinical results of balloon coronary angioplasty in patients with ischemic heart disease and three impaired coronary vessels].

AIM: To study a short-term clinical effect of balloon coronary angioplasty (BCA) in patients with affection of three coronary arteries regarding an anginal form and completeness of myocardial revascularization. MATERIAL AND METHODS: The study included 80 patients with coronary heart disease (CHD) having three affected major coronary arteries after BCA among them 48 patients with stable and 32 patients with unstable angina. The procedures were made using "Polydiagnost C" angiographic complex (Philips, Holland). RESULTS: Overall clinical efficacy of BCA in affection of three coronary arteries was 88.75% (in 71 of 80 patients), no response was observed in 9 of 80 patients (11.25%). The response to BCA was independent of the anginal form. In stable angina there were no differences in clinical efficacy in complete and incomplete functionally-adequate anatomic BCA (91 and 89.6%, respectively). In incomplete anatomic revascularization clinical effect was less (62.5%). In unstable angina a clinical effect of BCA did not depend on the degree of myocardial revascularization. Stenting raised clinical response to BCA in all the patients. CONCLUSION: The findings demonstrate high clinical efficacy of BCA in affection of three coronary arteries irrespective of an angina form. Incomplete anatomic revascularization in stable effort angina is less effective but can be used if other operations are impossible. If definition of the symptom-causing artery is possible, the intervention should be limited to BCA of this artery to decide on dilation of other arteries later.
