Effect of Sirolimus-eluting stent in actual clinical practice / 中国介入心脏病学杂志

ABSTRACT

Objective To sbserve the effect of sirolimus-eluting stent in actual clinical practice. Methods The study included 263 patients who had implanted the cypher stents from December 2002 to May 2004. The incidence of MACE was followed up in all patients 8?2 months after stent implantation by means of telephone or out-patient department visit. Evaluation of the therapeutic effect was also made in the diabetes subgroup and different types of lesions, including left main, bifurcation, chronic total occlusion, diffuse disease, in-stent restenosis, littlie vessel, acute occlusion, ostial lesions, and just A-type lesions. The rate of restenosis was observed in all of the lesion. Results Among 246 patients, all patients were successfully implanted with the cypher stents, 93.5% patients had been followed up, 10 (3.8%) patients had MACE. 139 (52.6%) patient were revised by angiography. The total rate of restenosis was 10.1%, and among it 12.9% was diabetes mellitus patients, 11.1% with chronic total occlusion, 11.3% with little vessel lesion, 10.0% with diffuse lesion, 22.2% with left main lesion, 18.1% with bifurcation, 11.1 with CTO 9.1% with ostial lesions, and 8.7% with A-type lesion lesion. Conclusion Cypher stent implantion was safe and effective in actual clinical proctice. The incidence rate of MACE was low in lesions such as chronic total occlusion, diffuse disease, in-stent restenosis, littlie vessel, acute occlusion, ostial lesions, and A-type lesion. It may be beneficial for patients who had left main, bifurcation, in-stent restenosis.
