目的:评价药物涂层支架在冠状动脉长病变内(病变长度≥20 mm)的临床疗效。方法:对 50 例冠心病患者行药物涂层冠状动脉内支架治疗(56只,药物长支架组),随机选择同期50例接受普通支架治疗(52 只,普通长支架组),比较两组支架置入情况及临床事件发生率。结果: 两组手术成功率相似(100% ∶98.0%, P>0.05)。平均随访(7.6±2.1) 个月,随访率85%,药物长支架组心绞痛复发率显著低于普通长支架组(6.82% ∶19.51%,P<0.05)。结论:冠心病患者应用药物涂层支架治疗长病变临床效果优于普通支架。
OBJECTIVE: To evaluate the clinical efficacy of drug-eluting stents in long coronary lesions (lesion length ≥ 20 mm). Methods: Fifty patients with coronary heart disease were treated with drug-coated coronary stent (56, long stent group). Fifty patients undergoing stent-graft therapy (52 long-term care group) Incidence and incidence of clinical events. Results: The success rates of the two groups were similar (100%: 98.0%, P> 0.05). The mean follow-up was (7.6 ± 2.1) months and the follow-up rate was 85%. The recurrence rate of angina in long stent group was significantly lower than that in long stent group (6.82% vs 19.51%, P <0.05). Conclusion: The clinical effect of applying drug-coated stent in patients with coronary heart disease is better than that of common stent.
