Where stroke occurs with pre-existing atrial fibrillation (AF)studies validating the safety and efficacy of bridging thrombolysis, and the use of endovascular thrombectomy (EVT) in the setting of prior anticoagulation, are limited to single-center reports.
In a retrospective analysis, AF patients undergoing EVT for anterior circulation large vessel occlusion stroke enrolled in a prospectively-maintained, international multicenter database (International Stroke Perfusion Imaging Registry (INSPIRE)) between 2016 and 2019 were studied. Patients were categorized by anticoagulation status: anticoagulated (warfarin/non-vitamin K oral anticoagulants) versus not anticoagulated. Patients not anticoagulated were further divided into intravenous thrombolysis versus no thrombolysis. Outcomes compared between groups included 90-day modified Rankin Scale, 90-day mortality, rates of symptomatic intracerebral hemorrhage (sICH), and good reperfusion (modified Thrombolysis In Cerebral Infarction (mTICI) 2b-3).
Of 563 AF patients, 118 (21%) were on anticoagulation. AF patients on anticoagulation showed improved 90-day functional outcomes (adjusted odds ratio (aOR) 1.68, 95% confidence interval (95% CI) 1.00 to 2.82). Mortality (26.3% vs 23.8%), sICH (4.5% vs 3.9%), and rates of good reperfusion (91.3% vs 88.0%) were similar between those anticoagulated and those not anticoagulated. Thrombolysis before EVT in AF patients was independently associated with improved 90-day functional outcomes (aOR 1.81, 95% CI 1.18 to 2.79) and reduced mortality (aOR 0.51, 95% CI 0.31 to 0.84), with similar sICH rates (3.4% vs 4.5%).
Anticoagulated patients with AF who underwent EVT had improved 90-day functional outcomes and similar sICH rates. Thrombolysis before EVT in AF patients was associated with improved 90-day functional outcomes and reduced mortality.
在伴有先前存在的心房颤动 (AF) 的情况下发生中风的情况下,验证桥接溶栓治疗以及在先前抗凝的情况下使用血管内血栓切除术 (EVT) 的安全性和有效性的研究仅限于单中心报告。
在回顾性分析中,研究了在 2016 年至 2019 年期间在一个前瞻性维护的国际多中心数据库(国际中风灌注成像登记处(INSPIRE))中接受 EVT 治疗前循环大血管闭塞性中风的 AF 患者。根据抗凝状态对患者进行分类:抗凝(华法林/非维生素 K 口服抗凝剂)与未抗凝。未抗凝的患者进一步分为静脉溶栓与无溶栓。组间比较的结果包括 90 天改良 Rankin 量表、90 天死亡率、症状性颅内出血 (sICH) 发生率和良好再灌注(改良脑梗死溶栓 (mTICI) 2b-3)。
在 563 名 AF 患者中,有 118 名(21%)正在接受抗凝治疗。接受抗凝治疗的 AF 患者 90 天功能结局得到改善(调整后的优势比(aOR)1.68,95%置信区间(95%CI)为 1.00 至 2.82)。死亡率(26.3% 比 23.8%)、sICH(4.5% 比 3.9%)和良好再灌注率(91.3% 比 88.0%)在抗凝组和未抗凝组之间相似。AF 患者 EVT 前溶栓与 90 天功能结局改善相关(aOR 1.81,95%CI 1.18 至 2.79)和死亡率降低(aOR 0.51,95%CI 0.31 至 0.84),sICH 发生率相似(3.4% 比 4.5%)。
接受 EVT 治疗的 AF 合并抗凝的患者 90 天功能结局改善,sICH 发生率相似。AF 患者 EVT 前溶栓与 90 天功能结局改善和死亡率降低相关。
