摘要 目的观察华法林不同强度抗凝对心房颤动患者的疗效及安全性,探讨低强度抗凝对国人心房颤动患者预防血栓栓塞发生的可行性。方法将至少有一个栓塞危险因素的心房颤动患者102例予以华法林抗凝治疗,根据国际标准化比值(INR)随机分为低强度抗凝组(INR1.60—2.50)50例和较高强度抗凝组(INR2.51—3.20)52例,观察2组血栓栓塞及出血事件发生率。结果低强度抗凝组栓塞事件发生率为2.O%(1/50),较高强度抗凝组栓塞事件发生率为1,9%(1/52),2组比较差异无显著性(P〉0.05)。低强度抗凝组出血事件发生率为2.0%(1/50),较高强度抗凝组出血事件发生率为9.6%(5/52),2组比较差异有显著性(P〈0.05)。结论华法林抗凝强度以INR为1.60~2.50水平时出血风险小,华法林低强度抗凝同样达到预防血栓栓塞的目的,同时相对安全。
