聚合物可降解支架对维持性血液透析合并急性冠状动脉综合征患者的疗效

目的探讨聚合物可降解药物洗脱支架(DES)治疗维持性血液透析(MHD)合并急性冠状动脉综合征患者的疗效。方法入选2008年1月至2013年7月沈阳军区总医院血液透析科100例MHD合并急性冠状动脉综合征的患者进行经皮冠状动脉介入治疗(PCI),将患者随机分为两组,置入EXCEL支架(聚合物可降解DES)组50例,置入FIREBIRD支架(普通DES)组50例。其中男61例,女39例,年龄43~74(58.4±9.2)岁。常规行PCI,术后EXCEL组患者服用阿司匹林(100 mg,每日一次)和氯吡格雷(75 mg,每日一次)双联抗血小板治疗(DAPT)6个月,随后长期服用阿司匹林(100 mg,每日一次);FIREBIRD组患者应用阿司匹林(100 mg,每日一次)和氯吡格雷(75 mg,每日一次)12个月,随后长期服用阿司匹林(100 mg,每日一次)。观察术后12个月患者主要不良心脑血管事件(MACCE)和出血事件的发生情况。结果两组患者入院时临床及造影基线资料差异无统计学意义(P0.05),住院期间未发生MACCE。术后12个月内两组患者MACCE发生率差异无统计学意义(P0.05),未发生支架血栓。术后12个月内EXCEL组主要出血1例,为消化道溃疡所致;FIREBIRD组主要出血2例,均为脑出血。FIREBIRD组总出血事件显著高于EXCEL组(P0.05)。结论聚合物可降解DES治疗MHD合并ACS患者有效,应用6个月的DAPT是安全的。

Effect of biodegradable polymer DES on maintenance hemodialysis patients with acute coronary syndrome

Objective To study the effect of biodegradable polymer drug-eluting stents （DES） on maintenance hemodialysis （MHD） patients with acute coronary syndrome. Methods From 2008 January to 2013 July, a total of 100 MHD patients with ACS who were treated with PCI in our centre were randomly divided into two groups, 50 patients in the EXcellstent group （biodegradable polymer DES） and the others in the FIREBIRD stent group （Ordinary DES）. The patients included 61 male and 39 female, while the mean age was （58.4±9.2） years old （43-74 years old）. After procedure, the EXcellstent group patients took aspirin （100 mg qd） and clopidogrel （75 mg qd） for 6 months, then aspirin （100 mg qd） for lifelong. The FIRDBIRD stent group patients also took aspirin （100 mg qd） and clopidogrel （75 mg qd）, then aspirin （100 mg qd） lifetime too. To observe the main adverse cardiovascular and cerebrovascular events （MACCE） and bleeding events during 12 months after procedure. Results The clinical data and angiographic results had no significant difference. No MACCE occurred during hospitalization. In 12 months after PCI, MACCE had no significant difference between two groups （P〉0.05）, and no stent thrombosis occured. One patient presented gastroin testinal bleeding in the EXcellgroup and 2 patients had cerebral hemorrhage in the FIRBIRD group. FIRBIRD group had more total hemorrhages events than that in EXcellgroup （P〈0.05）. Conclusions The treatment of biodegradable polymers DES in MHD patients with ACS was effective, and dual anti-platelet for 6 months was safe.
