JAMA:抗凝治疗与脑出血死亡风险

2018-02-07 zhangfan MedSci原创

研究认为,非维生素k拮抗剂口服抗凝血剂或华法林导致患者脑出血院内死亡风险增加,抗凝药的脑出血死亡风险华法林高于非维生素K拮抗剂口服抗凝血剂

非维生素K拮抗剂口服抗凝血剂(NOAC,新型抗凝药,如利伐沙班,达比加群等)越来越多地被用于血栓栓塞性疾病的预防,但有关NOAC相关性脑出血(ICH)研究尚不充分。近日研究人员考察了抗凝剂(华法林vs非维生素K拮抗剂口服抗凝血剂)与脑出血死亡之间的相关性。

141311名患者参与研究,患者入院前至少接受7天的抗凝治疗,研究的主要终点为住院死亡率。

141311名ICH患者平均年龄68.3岁,女性占48.1%,其中15036人(10.6%)服用华法林,4918人(3.5%)服用NOAC,分别有39585(28.0%)和5783(4.1%)人服用单或双重抗血小板药。华法林及NOAC患者年龄较大,房颤及中风发病率较高。组间急性脑卒中严重程度差异不显著,NIHSS评分分别为9 vs 8 vs 8。华法林vs NOAC vs 无抗凝组患者住院期间脑出血死亡率分别为32.6% vs 26.5% vs 22.5%。相对于未接受抗凝治疗患者,华法林(ARD,9.0%;AOR,1.62)以及NOAC(ARD, 3.3%; AOR, 1.21)治疗者院内死亡风险增加。相对于华法林治疗组,NOAC患者院内死亡风险降低(ARD,5.7%; AOR, 0.75)。亚组分析显示,对于之前接受过双重抗血小板药物治疗的患者,相比于未接受抗血小板药治疗的患者,接受NOAC或华法林导致的死亡风险差异更为显著。

研究认为,非维生素k拮抗剂口服抗凝血剂或华法林导致患者脑出血院内死亡风险增加,抗凝药的脑出血死亡风险华法林高于非维生素K拮抗剂口服抗凝血剂。
