JAMA:首发自发性肺栓塞的抗凝治疗的更佳持续时间

2015-07-15 MedSci MedSci原创

首发的自发性肺栓塞的抗凝治疗的最佳持续时间是不确定的。本研究旨在研究在初始6个月的维生素K拮抗剂非随机治疗期后,确定另外18个月的华法林与安慰剂治疗的益处和危害。    这项随机,双盲试验(治疗期18个月;中位随访24个月),招募了来自于法国14个中心的经历首发自发性肺栓塞(即与血栓形成无重大风险因素)的371例成年患者,并用维生素K拮抗剂不间断地初步治疗了6个月。他

首发的自发性肺栓塞的抗凝治疗的最佳持续时间是不确定的。本研究旨在研究在初始6个月的维生素K拮抗剂非随机治疗期后,确定另外18个月的华法林与安慰剂治疗的益处和危害。
    
这项随机,双盲试验(治疗期18个月;中位随访24个月),招募了来自于法国14个中心的经历首发自发性肺栓塞(即与血栓形成无重大风险因素)的371例成年患者,并用维生素K拮抗剂不间断地初步治疗了6个月。他们被随机分配,随访时间为2007年7月到2014年9月。干预方法为18个月的华法林和安慰剂治疗。主要结果是随机分组后18个月的复发性静脉血栓栓塞或大出血的复合终点。次要结果为42个月(治疗期加上24个月的随访)的复合终点,以及在18和42个月时复合终点的和肺栓塞无关的死亡或大出血的结果。
    
随机分组后,4例患者失去随访,18个月后1例患者由于不良事件退出随访。在18个月的治疗期间,华法林组中的184例患者中主要的结果发生了6例(3.3%),安慰剂组中187例患者主要发生了25例(13.5%)(危险比[HR],0.22;95%Cl ,0.09-0.55;P=0.001)。华法林组复发性静脉血栓栓塞发生3例,安慰剂组发生25例(HR,0.15;95%Cl,0.05-0.43);华法林组大出血发生4例,安慰剂组发生1例(HR,3.96;95%Cl,0.44〜35.89)。

在42个月的整个研究期间(包括研究治疗和随访期间),华法林组复合终点发生33例(20.8%),安慰剂组发生42例(24.0%)(HR,0.75;95%Cl,0.47-1.18)。复发性静脉血栓栓塞、严重出血以及无关性死亡没有明显组间差异。
    
在那些首发自发性肺栓塞后并接受6个月抗凝治疗的患者中,与安慰剂相比,另外18个月的华法林治疗可减少复发性静脉血栓形成和主要出血。然而,抗凝治疗停药后不能继续继续保持该有益作用。
