摘要
目的:比较达比加群、华法林用于心房颤动患者射频消融术(RFCA)后的疗效和安全性。方法:回顾性分析141例非瓣膜性心房颤动并拟行RFCA患者资料,按用药的不同分为华法林组(71例)和达比加群组(70例)。华法林组患者入院前曾服华法林者入院后需停用,改为低分子肝素钙注射液100 U/kg,皮下注射,待INR<1.5时行RFCA,术前12 h停用低分子肝素钙注射液;术中静脉注射肝素钙注射液100 U/kg;术后4~6 h口服华法林钠片4.5 mg,每日1次,同时与低分子肝素桥接重叠治疗至少3~5 d;术后每3 d监测1次国际标准化比值(INR),维持INR 2.0~3.0,至少服用华法林3个月。达比加群组患者入院后停用曾服用的抗凝药物,改为口服达比加群酯胶囊110 mg(年龄≥70岁或体质量<60 kg)或150 mg(年龄<70岁或体质量≥60 kg),每日2次;术前24 h停用达比加群酯胶囊,术中用药同华法林组;术后6 h口服达比加群酯胶囊,至少服用3个月。观察两组患者术后第1、3个月总死亡率、脑卒中(短暂性脑缺血,缺血性脑病)发生率、外周血管栓塞率及出血情况。结果:两组患者术后第1、3个月总死亡率、脑卒中发生率、外周血管栓塞率、出血发生率比较,差异均无统计学意义(P>0.05)。结论:达比加群用于非瓣膜性心房颤动患者RFCA的抗凝疗效和安全性均与华法林相当。
OBJECTIVE:To compare the efficacy and safety of dabigatran and warfarin respectively used in atrial fibrillation patients after radiofrequency ablation(RFCA). METHODS:Data of 141 nonvalvular atrial fibrillation patients,who scheduled for RFCA,were retrospectively analyzed and divided into warfarin group(71 cases)and dabigatran group(70 cases)by different med-ication. Patients in warfarin group should stop warfarin if they took before,then changed to Low molecular weight heparin calcium injection 100 U/kg,subcutaneous injection,taking RFCA when INR was lower than 1.5,stopping low molecular weight heparin 12 h before surgery;Low molecular weight heparin calcium injection 100 U/kg was intravenously injected when surgery;orally tak-ing Warfarin sodium tablet 4.5 mg after 4-6 h,once a day,meanwhile bridged overlapping treated at least 3-5 d with low molecu-lar weight heparin;monitoring once INR every 3 d after surgery,maintaining INR 2.0-3.0,taking warfalin at least 3 months. Pa-tients in dabigatran group stopped taking the anticoagulant drugs when admission,then changed to Dabigatran etexilate capsule 110 mg(age≥70 years old or body mass〈60 kg)or 150 mg(age〈70 years old or body mass≥60 mg),twice a day;stopping dabig-atran 24 h before surgery,the same medication as warfalin group when surgery;orally taking dabigatran after 6 h,taking at least 3 months. The total mortality rate,incidence of stroke(transient cerebral ischemia,ischemic encephalopathy),peripheral thrombosis rate and incidence of bleeding after 1 and 3 month(s)in 2 groups were observed. RESULTS:There were no significant differences in the total mortality rate,incidence of stroke,peripheral thrombosis rate and incidence of bleeding after 1 and 3 month(s) in 2 groups(P〉0.05). CONCLUSIONS:Dabigatran has similar anticoagulant efficacy and safety with warfarin in atrial fibrillation pa-tients after RFCA.
