Stroke:升高的国际标准化比值与破裂的动脉瘤相关

2018-08-11 xing.T MedSci原创

由此可见,INR升高与颅内动脉瘤破裂有关,但华法林可以缓解这种效应。因此,在咨询颅内动脉瘤的患者时应考虑INR值。

抗凝治疗和国际标准化比值(INR)升高对动脉瘤性蛛网膜下腔出血风险的影响尚不清楚。我近日,卒中领域权威杂志Stroke上发表了一篇研究文章,研究人员目的是探究抗凝治疗,INR值升高,与颅内动脉瘤破裂之间的关系。

研究人员对4696名患有6403处颅内动脉瘤的患者进行了病例对照研究,其中包括1198名前瞻患者,这些患者于1990年至2016年期间在马萨诸塞州综合医院和布莱根妇女医院得到诊断,并未接受抗凝治疗或使用华法林进行抗凝治疗。患者分为破裂组和非破裂组。研究人员采用单变量和多变量逻辑回归分析来评估抗凝治疗、INR值与颅内动脉瘤破裂的关系,同时考虑抗凝剂使用与INR之间的相互作用。研究人员通过倾向得分的逆概率加权用于最小化基线人口统计特征的差异,并根据INR值分层的破裂风险计算抗凝剂使用的边际效应。

在未加权和加权多变量分析中,INR值升高与未抗凝治疗患者的破裂状态显著相关(未加权比值比为22.78; 95%CI为10.85-47.81和加权比值比为28.16; 95%CI为12.44-63.77)。在抗凝患者中,当INR≥1.2时,通过降低INR对破裂风险的影响,华法林使用与INR存在显著相互作用。

由此可见,INR升高与颅内动脉瘤破裂有关,但华法林可以缓解这种效应。因此,在咨询颅内动脉瘤的患者时应考虑INR值。

PLoS One:服用华法林的房颤患者,应密切关注INR值

目的:维生素K拮抗剂(VKAs)需要单独给药。用于房颤患者的卒中预防(AF),国际指南推荐的国际标准化比值(INR)目标范围为2-3。研究者在持续的,全球性的,观察性记录试验(GARFIELD-AF),分析新发房颤的患者在治疗VKA治疗范围内(TTR)的时间。将TTR作为衡量患者管理质量得指标,研究者分析与1年结局的相关性,包括卒中/全身性栓塞(SE)、大出血和全因死亡率。方法和结果:9934例患

PLoS One:大血管闭塞可行静脉溶栓

背景:研究者探讨大血管闭塞(MVO)和服用华法林的心源性栓塞高危患者的国际标准化比值(INR)的相关性。研究者评估MVO闭塞是否可预测INR≤1.7及静脉溶栓的安全性相关。方法: 对2008年4月到2015年3月期间,服用华法林的177心源性卒中患者进行回顾性分析。Logistic回归分析计算比值比(OR)和95%置信区间(95%CI)评估血管闭塞和INR的关联。为了预测≤INR 1.7,应用决策

JAMA:大部分接受华法林治疗的患者未能随时间推移维持稳定的国际标准化比值

据发表于JAMA的一项研究表明,大部分接受华法林治疗的患者未能随时间推移维持稳定的国际标准化比值(INR)。该研究发现挑战了人们的一贯看法:华法林预后好的患者应继续使用华法林而不应换成非维生素K口服抗凝药。 华法林可大大降低房颤患者卒中的发生风险,但是其治疗窗很窄(INR值,2.0-3.0),且与食物和药物相互作用有关。非维生素K口服抗凝药不需要药物检测,且与华法林的效果及安全性相似,甚至可

华法林抗凝,INR异常如何处理?

华法林是一种口服抗凝药,具有作用时间长、服用方便、副作用相对小、价格低廉等优点,被广泛应用于静脉血栓栓塞性疾病(VTE)、房颤血栓栓塞、瓣膜病、人工瓣膜置换术和心腔内血栓形成等的预防治疗中。

Hepatology:慢加急性肝功能衰竭(ACLF)和失代偿性肝硬化(INR)患者凝血功能衰竭

慢加急性肝衰竭患者经常表现出低凝血特征,纤维蛋白形成时间延长、血栓形成时间延长和凝块硬度降低。这些变化在入院后恶化,与全身炎症相关,患者短期死亡率较高。

Hepatology:急性肝衰竭导致出血并发症

尽管有出血倾向,临床上ALF患者显著的出血并不常见。出血并发症是严重系统性炎症的标志,而非凝血功能障碍,预示预后不良
