目的观察Cypher及Taxus药物洗脱支架治疗冠心病的疗效。方法应用冠状动脉造影随访162例接受Cypher及Taxus药物洗脱支架置入术的冠心病患者,其中Cypher组93例,Taxus组69例。结果Cypher组和Taxus组再狭窄率分别为10.8%和11.6%,靶病变再血管化率分别为5.4%和5.8%,两组比较差异均无统计学意义。支架内晚期管径丢失及支架节段晚期管径丢失在Cypher组低于Taxus组,两组间差异有统计学意义。结论药物洗脱支架可有效降低介入治疗术后再狭窄的发生率,但Cypher组支架内晚期管径丢失低于Taxus组。
Objective To observe the efficacy of Cypher and Taxus drug-eluting stents in the treatment of coronary heart disease. Methods Coronary angiography was followed up in 162 patients with coronary heart disease undergoing Cypher and Taxus stent implantation, 93 patients in Cypher group and 69 in Taxus group. Results The restenosis rates in Cypher group and Taxus group were 10.8% and 11.6%, respectively. The rates of revascularization in target group were 5.4% and 5.8% respectively. There was no significant difference between the two groups. Late stent diameter loss and stent segment late tube diameter loss in the Cypher group was lower than the Taxus group, with a significant difference between the two groups. Conclusion The drug-eluting stent can effectively reduce the incidence of restenosis after PCI, but the late stent loss in Cypher group is lower than that in Taxus group.
