Efficiency of antiproliferative stents in treating restenosis of previously implanted coronary stents

162 patients with clinical recurrence of angina over a month after primary stenting with metal stents were included in this multipurpose study of the efficiency of antiproliferative stents in treating restenosis of previously implanted CA stents. Sirolimus-coated stents (Cypher, J&J, USA) were successfully implanted in the patients. During the observation period (9 months) minimum lumen loss amounted to 0.08±0.49 mm, which led to the occurrence of restenosis development equal to 9.7% and the frequency of repeated interventions - 7.4%.
