BACKGROUND: Intravenous thrombolysis (IVT) is an effective stroke therapy that remains underused. Currently, the use of IVT in patients with recent direct oral anticoagulant (DOAC) intake is not recommended. In this study we aim to investigate the safety and efficacy of IVT in patients with acute ischemic stroke and recent DOAC use. METHODS AND RESULTS: A systematic review and meta-analysis of proportions evaluating IVT with recent DOAC use was conducted. Outcomes included symptomatic intracranial hemorrhage, any intracranial hemorrhage, serious systemic bleeding, and 90-day functional independence (modified Rankin scale score 0-2). Additionally, rates were compared between patients receiving IVT using DOAC and non-DOAC by a random effect meta-analysis to calculate pooled odds ratios (OR) for each outcome. Finally, sensitivity analysis for idarucizumab, National Institutes of Health Stroke Scale, and timing of DOAC administration was completed. Fourteen studies with 247 079 patients were included (3610 in DOAC and 243 469 in non-DOAC). The rates of IVT complications in the DOAC group were 3% (95% CI, 3-4) symptomatic intracranial hemorrhage, 12% (95% CI, 7-19) any ICH, and 0.7% (95%CI, 0-1) serious systemic bleeding, and 90-day functional independence was achieved in 57% (95% CI, 43-70). The rates of symptomatic intracranial hemorrhage (3.4 versus 3.5%; OR, 0.95 [95% CI, 0.67-1.36]), any intracranial hemorrhage (17.7 versus 17.3%; OR, 1.23 [95% CI, 0.61-2.48]), serious systemic bleeding (0.7 versus 0.6%; OR, 1.27 [95% CI, 0.79-2.02]), and 90-day modified Rankin scale score 0-2 (46.4 versus 56.8%; OR, 1.21 [95% CI, 0.400-3.67]) did not differ between DOAC and non-DOAC groups. There was no difference in symptomatic intracranial hemorrhage rate based on idarucizumab administration. CONCLUSIONS: Patients with acute ischemic stroke treated with IVT in recent DOAC versus non-DOAC use have similar rates of hemorrhagic complications and functional independence. Further prospective randomized trials are warranted.
背景:静脉溶栓(IVT)是一种有效的脑卒中治疗方法,但使用率仍然较低。目前,不建议在近期直接口服抗凝剂(DOAC)使用的患者中使用 IVT。本研究旨在探讨近期使用 DOAC 的急性缺血性脑卒中患者接受 IVT 的安全性和疗效。
方法和结果:系统回顾和比例评估最近使用 DOAC 进行 IVT 的荟萃分析。结果包括症状性颅内出血、任何颅内出血、严重全身性出血和 90 天功能独立性(改良 Rankin 量表评分 0-2)。此外,通过随机效应荟萃分析比较接受 IVT 的患者中 DOAC 和非 DOAC 的比率,以计算每种结局的汇总优势比(OR)。最后,完成了针对依达鲁单抗、国立卫生研究院卒中量表和 DOAC 给药时间的敏感性分析。纳入了 14 项研究,共 247079 例患者(DOAC 组 3610 例,非 DOAC 组 243469 例)。DOAC 组的 IVT 并发症发生率为 3%(95%CI,3-4)症状性颅内出血、12%(95%CI,7-19)任何 ICH 和 0.7%(95%CI,0-1)严重全身性出血,90 天功能独立性达到 57%(95%CI,43-70)。症状性颅内出血(3.4%与 3.5%;OR,0.95[95%CI,0.67-1.36])、任何颅内出血(17.7%与 17.3%;OR,1.23[95%CI,0.61-2.48])、严重全身性出血(0.7%与 0.6%;OR,1.27[95%CI,0.79-2.02])和 90 天改良 Rankin 量表评分 0-2(46.4%与 56.8%;OR,1.21[95%CI,0.400-3.67])在 DOAC 和非 DOAC 组之间无差异。依达鲁单抗给药与症状性颅内出血发生率无差异。
结论:在近期使用 DOAC 与非 DOAC 的急性缺血性脑卒中患者中,接受 IVT 治疗的患者出血并发症和功能独立性的发生率相似。需要进一步进行前瞻性随机试验。
