摘要
目的:应用2010年欧洲心脏病学协会(ESC)房颤新指南提出的新的评分系统卒中危险评分(CHA2DS2-VASc)和首次推出的出血风险评分法(HAS-BLED),观察CHA2DS2-VASc积分≥1分且HAS-BLED出血风险积分≥3分时,低强度华法林抗凝治疗高出血风险房颤患者的抗栓疗效和安全性。方法2011年1月至2012年1月我院非瓣膜性房颤患者99例,其CHA2DS2-VASc卒中危险评分≥1分且HAS-BLED出血风险积分≥3分。全部病例分成两组,标准强度华法林治疗组[2.0<国际标准化比值(INR)≤3.0]和低强度华法林治疗组(1.6≤INR≤2.0)。观察两组患者的血栓栓塞率及出血发生率。结果卡方检验结果显示,两组患者的血栓栓塞率差异无统计学意义(P>0.05);标准强度华法林治疗组的出血发生率高于低强度华法林治疗组患者,差异有统计学意义(P<0.05)。结论 CHA2DS2-VASc卒中危险评分≥1分且HAS-BLED出血风险积分≥3分的高出血风险的房颤患者可以采用低强度华法林抗凝,能有效减少血栓栓塞事件的发生,同时不增加严重出血事件,使用安全可靠。
Objective To determine the safety and availability of anticoagulation of low-intensity warfarin therapy in atrial fibrillation (AF) patients with high risk of stroke and bleeding applying stroke risk score (CHA2DS2-VASc) and bleeding risk score (HAS-BLED) (CHA2DS2-VASc≥1 and HAS-BLED≥3) proposed by 2010 European Society of Cardiology Guideline. Methods A total of 99 AF patients who had the stroke risk scoring CHA2DS2-VASc≥1 and HAS-BLED score≥3 admitted in our hospital from January 2011 to January 2012 were selected randomly, and then divided into 2 groups. One group was treated by a standard intensity warfarin therapy of 2.00.05). The incidence of bleeding was significantly higher in standard-intensity Warfarin group than in low-intensity Warfarin group (P〈0.05). Conclusion AF patients with high bleeding risk (CHA2DS2-VASc≥1 and HAS-BLED score≥3) should be treated by low-intensity warfarin anticoagulation. The therapy is safe and reliable, with advantages of suppressing thrombosis and embolism events and not increasing serious hemorrhage.
