Abstract
Introduction: People with atrial fibrillation (AF) frequently have competing mechanisms for ischaemic stroke, including extracranial carotid atherosclerosis. The objective of this study was to determine associations between use of oral anticoagulants (OACs) plus antiplatelet agents (APA) after ischaemic stroke and outcomes for patients with AF and carotid artery disease.
Patients and methods: A retrospective cohort study was conducted. Participants receiving OACs with or without APA were propensity score-matched for age, sex, ethnicity, co-morbidities and presence of cardiac and vascular implants and grafts. Outcomes were 1-year mortality, recurrent stroke and major bleeding.
Results: Of 5708 patients, 24.1% (n=1628) received non-vitamin K antagonist OACs (NOACs) with no APA, 26.0% (n=1401) received NOACs plus APA, 20.7% (n=1243) received warfarin without APA and 29.2% (n=1436) received warfarin plus APA. There was no significant difference in risk of recurrent stroke between the groups. Compared to receiving NOACs without APA, receiving warfarin plus APA was associated with a higher risk of mortality (hazard ratio (HR) 1.51 (95% confidence interval (CI) 1.20, 1.89)) and major bleeding (HR 1.66 (95% CI 1.40, 1.96)). Receiving NOACs plus APA was also associated with a higher risk of major bleeding compared to NOACs without APA (HR 1.27 (95% CI 1.07, 1.51), respectively).
Conclusions: The results suggest for patients with AF and carotid artery disease after ischaemic stroke, receiving NOACs without APA is associated with a lower risk of major bleeding with no negative impact on recurrent stroke or mortality. Evidence from randomised trials is needed to confirm this finding.
导言:心房颤动(AF)患者经常有缺血性中风的竞争机制,包括颅外颈动脉粥样硬化。本研究旨在确定缺血性中风后使用口服抗凝药(OAC)加抗血小板药(APA)与心房颤动和颈动脉疾病患者的预后之间的关系:进行了一项回顾性队列研究。根据年龄、性别、种族、合并疾病以及是否存在心脏和血管植入物和移植物,对接受或不接受 APA 的 OACs 的参与者进行倾向评分匹配。结果为 1 年死亡率、复发性中风和大出血:在5708名患者中,24.1%(n=1628)接受了不含APA的非维生素K拮抗剂OACs(NOACs),26.0%(n=1401)接受了NOACs加APA,20.7%(n=1243)接受了不含APA的华法林,29.2%(n=1436)接受了华法林加APA。各组间的复发性中风风险无明显差异。与接受不含 APA 的 NOACs 相比,接受华法林加 APA 与更高的死亡风险(危险比 (HR) 1.51(95% 置信区间 (CI) 1.20,1.89))和大出血风险(HR 1.66(95% CI 1.40,1.96))相关。与不服用APA的NOACs相比,服用NOACs加APA也与较高的大出血风险相关(HR分别为1.27(95% CI 1.07,1.51)):结果表明,对于缺血性卒中后合并房颤和颈动脉疾病的患者,接受不含 APA 的 NOACs 与较低的大出血风险相关,但对复发卒中或死亡率无负面影响。需要随机试验的证据来证实这一发现。
