摘要

目的

系统评价新型口服抗凝药（NOACs）用于非瓣膜性房颤患者左心耳封堵（LAAO）术后抗栓的有效性和安全性。

方法

计算机检索PubMed、Embase、Web of Science、Cochrane图书馆、中国知网、万方数据，收集NOACs（试验组）对比华法林或双联抗血小板药（对照组）的随机对照试验（RCT）和队列研究，检索时限为建库至2022年11月。筛选文献、提取数据、评价质量后，采用RevMan 5.4软件进行Meta分析。

结果

纳入10项研究，包括2项RCT、8项队列研究，共计2 653例患者。RCT结果显示，两组患者的器械相关性血栓（DRT）发生率、卒中/全身性栓塞（SSE）发生率、大出血事件发生率、总出血事件发生率、全因死亡率比较，差异均无统计学意义（

＞0.05）。队列研究结果显

示，与双联抗血小板药比较，试验组患者的DRT发生率、卒中/SSE发生率、大出血事件发生率、全因死亡率差异均无统计学意义（

＞0.05）；与华法林比较，试验组患者的DRT发生率[RR＝0.40，95%CI（0.19，0.82），

＝0.01

]

、总出血事件发生率[RR＝0.28，95%CI（0.18，0.44），

＜0.000 01

]

均显著降低，而卒中/SSE发生率、大出血事件发生率、全因死亡率差异均无统计学意义（

＞0.05）。

结论

NOACs用于非瓣膜性房颤患者LAAO术后的疗效和安全性与双联抗血小板药相当，DRT发生率和总出血事件发生率低于华法林。

Abstract

OBJECTIVE

To systematically evaluate the efficacy and safety of new oral anticoagulants （NOACs） in patients with nonvalvular atrial fibrillation after left atrial appendage occlusion （LAAO）.

METHODS

Retrieved from PubMed， Embase， Web of Science， the Cochrane Library， CNKI and Wanfang data， randomized controlled trials （RCTs） and cohort studies about NOACs （trial group） versus warfarin or dual antiplatelet agents （control group） were collected during the inception and November 2022. After literature screening， data extraction and quality evaluation， meta-analysis was performed by using RevMan 5.4 software.

RESULTS

A total of 10 studies were included， involving 2 RCTs and 8 cohort studies， with a total of 2 653 patients. RCT results showed that there was no statistically significant difference in the incidence of device-related thrombosis （DRT）， stroke/systemic embolism （SSE）， major bleeding events， total bleeding events or all-cause mortality between 2 groups （

＞0.05）. Results of cohort studies showed that compared with dual antiplatelet agents， there was no statistically significant difference in the incidence of DRT， stroke/SSE， major bleeding events or all-cause mortality in the trial group （

＞0.05）. Compared with warfarin， the incidence of DRT [RR＝0.40， 95%CI　（0.19，0.82），

＝0.01

]

and total bleeding events [RR＝0.28， 95%CI　（0.18， 0.44），

＜0.000 01

]

in the trial group were decreased significantly； there was no statis

tical significance in the incidence of stroke/SSE， major bleeding events or all-cause mortality （

＞0.05）.

CONCLUSIONS

For patients with nonvalvular atrial fibrillation after LAAO， NOACs have comparable antithrombotic efficacy and safety with dual antiplatelet agents， and the incidence of DRT and total bleeding events are lower than warfarin.
