title: [Efficacy and safety of the TAIS coronary stent implantation: nine month multicenter study].
abstract: OBJECTIVE
  Assessment of clinical and angiographic results of a balloon-expandable steel matrix stent TAIS in patients with atherosclerosis of the coronary arteries with no history of previous interventions in the course of an open non-randomized multicenter trial.
  
  
  METHODS
  The TAIS stent was implanted in 187 patients into 199 stenoses. 47% patients had clinical manifestations of unstable angina pectoris. 29% cases were complicated. The length of the stenoses reached 11.3 +/- 5.4 mm, 22% stenoses were prolonged.
  
  
  RESULTS
  This coronary stenting was effective in 100% cases, neither acute nor subacute thromboses were seen. Myocardial infarction without occlusion of the stent developed in 3 patients. The incidence of cardial complications (death, angina, restenosis, repeated revascularization) in 6 month follow-up was 11.8%. An angiographic control in 6 months was made in 184 patients (194 stenoses). The vascular diameter loss index was 0.40 +/- 0.21, a restenosis level--10.7%. A logistic regression analysis has revealed significant correlations between the length of the stent and a target vascular diameter with subsequent restenosis. Repeated revascularization was performed in all the patients with stent restenosis. After control angiography cardiac complications developed in 13.9% patients. Nine month follow-up registered cardiac complications in 17.6% cases.
  
  
  CONCLUSIONS
  The TAIS stent was found effective in prevention of thrombosis and restenosis in patients with a relatively high risk of intervention.
