| 中文摘要:目的 观察口服华法林低强度抗凝相对于阿司匹林抗血小板治疗对心房颤动血栓事件的作用,并探讨血浆蛋白C及蛋白S活性变化及临床意义。方法 选择笔者医院于2012年6月~2013年6月收治72例老年心房颤动患者作为研究对象,采用数字表法随机分组,每组36例,观察组采取华法林低强度抗凝,初始剂量为2.5mg/d,调整剂量使INR控制在1.5~2.5,对照组采取阿司匹林治疗,均测定两组患者抗凝前后血浆蛋白C及蛋白S活性,比较两组患者疗效及血浆蛋白C及蛋白S活性。结果 两组出血发生率比较差异无统计学意义(P>0.05)。观察组共血栓发生率1(2.78%)明显低于对照组6例(16.67%)(P<0.05)。抗凝后观察组PC、PS活性均低于对照组(P<0.05)。观察组抗凝后与抗凝前比较PC、PS活性降低(P<0.05)。结论 口服华法林低强度抗凝应用于心房颤动患者效果明显,低强度华法林虽降低血浆蛋白C及蛋白S活性,并未增加血栓事件发生率。 |

| Abstract:Objective To investigate effect of low intensity anticoagulation versus antiplatelet therapy for prevention of thromboembolism in patients with non-valvular atrial fibrillation, and observe the changes of Protein C and S ability. Methods A total of 72 cases of patients with atrial fibrillation admitted in our hospital from June 2012 to June 2013 were enrolled and divided into two groups with 36 cases in each group randomly.The treatment group received warfarin with first dose of 2.5mg followed by this dose per day and INR were controlled at 1.5-2.5 by dose titration. The control group received aspirin 100mg per day, and plasma Protein C and Protein S activity were measured before and after treatment. Results The bleeding rate had no significant difference between two groups(P>0.05). The incidence of thrombosis in the treatment group was 2.78% and significantly lower than that of the control group(16.67%, P<0.05). After anticoagulation, the activity of PC and PS in observation group were lower than that of the control group(P<0.05). PC and PS activity in the treatment group decreased significantly after anticoagulation(P<0.05). Conclusion The effect of low intensity anticoagulation on prevention of thromboembolism in patients with non-valvular atrial fibrillation is obvious, and low intensity anticoagulation decreased activity of protein C and protein S with no elevated rate of thrombosis. |
