title: [Immediate and Remote Results of Endovascular Recanalization of Chronic Coronary Artery Occlusions]
abstract: We compared early and long-term follow-up results of balloon angioplasty and stenting of chronic coronary occlusions. The initial success rate was 75% (82 of 109 patients). Proportion of patients free of angina was 57 and 69% after successful balloon angioplasty and stenting, respectively. Stenting of coronary occlusions yielded better immediate angiographic results than did balloon angioplasty: residual stenosis and minimal diameter of artery after stenting were 13.5-12.4% and 2.7-0.2 mm, respectively; those after balloon angioplasty were 23.2-15.6% and 2.3-0.2 mm, p<0,05, respectively. Four-year clinical outcome was better in stenting than in angioplasty group: free of angina were 52 and 22% of patients in stenting and angioplasty group, respectively (p<0,05). There was no difference at follow-up between two groups in the rate of myocardial infarction, death, repeat revascularization. Repeat coronary angiography was performed after 38-24 months in 44% of patients. The rate of 'late' restenosis was 32% in stenting and 73% in balloon angioplasty group (p<0,05); mean stenosis and minimal diameter of artery after stenting were 43.5-12.4% and 1.7-0.6 mm, respectively; those after balloon angioplasty were 67.5-15.6% and 0.72+0.5 mm, respectively (p<0,05).
