Chest:华法林对终末期慢性肾病患者可能带来不利

2015-11-03 徐媛 MedSci原创

合并房颤的终末期慢性肾病患者使用华法林抗凝后大出血风险增加。该研究分析评价了房颤合并非终末期慢性肾病患者使用华法林后缺血性卒中/血栓(IS/TE)形成风险以及死亡率。研究人员检索了PUBMED, EMBASE, CINAHL, ProQuest和Google Scholar等电子数据库,并手动搜索了相关引用文献。研究者使用随机效应模型对非终末期慢性肾病患者与

合并房颤的终末期慢性肾病患者使用华法林抗凝后大出血风险增加。该研究分析评价了房颤合并非终末期慢性肾病患者使用华法林后缺血性卒中/血栓(IS/TE)形成风险以及死亡率。

研究人员检索了PUBMED, EMBASE, CINAHL, ProQuest和Google Scholar等电子数据库,并手动搜索了相关引用文献。研究者使用随机效应模型对非终末期慢性肾病患者与终末期慢性肾病患者(接受肾移植治疗)进行了独立分析。

研究人员共纳入13篇论文,其中涉及到11个队列(6项为回顾性研究,5项为前瞻性研究),包含48500多名患者和11600多名华法林使用者。房颤合并非终末期慢性肾病患者使用华法林后缺血性卒中/血栓形成风险降低(HR 0.7;95% CI,0.54-0.89)和死亡率(HR 0.65;95% CI,0.59-0.72)降低,而且并未发现华法林对大出血风险有影响(HR 1.15;95% CI,0.88-1.49)。但在房颤合并终末期慢性肾病患者中,华法林似乎并未减少受试者的卒中(HR= 1.12;95% CI,0.69-1.82)及死亡(HR= 0.96;95% CI,0.81-1.13)风险,且受试者的大出血风险增加(HR 1.3;95% CI,1.08-1.56)。

基于以上分析发现,华法林对终末期慢性肾病患者带来不利,但为非终末期慢性肾病患者带来获益。

房颤的抗凝治疗
