One year effect of rapamycin eluting stent in patients with coronary heart disease / 介入放射学杂志

ABSTRACT

Objective To evaluate the long-term results of rapamycin eluting stent in patients with coronary heart disease.Methods From Dec. 2001 to Nov. 2002, 143 patients were treated with 173 rapamycin eluting stents. Sixteen stents were implanted directly, the others were implanted with pre-dilation. Post-dilations were performed in 52 stents. All patients were administered aspirin and clopidogrel regularly before and after the procedures. Results Procedural succees rate reached 99.3% with completion of the follow-up in 138 patientes averaging (12.8 ?4.3) months. Thirteen patients has suffered with recurrent angina and 1 had acute myocardial infarction. Thirty eight patients received repetition of coronary angiography within 6 to 12 months after the procedure. Five patients showed instent restenosis, of which 4 received target lesion revascularization. The restenosis rate was 13.2% by angiography.Conclusion Rapamycin eluting stent can be used safely and effectively in patient with coronary heart disease, having long-term effect to reduce the restenosis rate after PCI.
