Abstract

Background: Asians with atrial fibrillation carry a higher risk of ischemic stroke than non-Asians even under treatment of nonvitamin K antagonist oral anticoagulants. The purpose of the study was to observe the feasibility of intravenous thrombolytic therapy after administering a reversal agent, idarucizumab, in dabigatran-treated patients with acute ischemic stroke in Taiwan.<br />Methods: Dabigatran-treated patients with acute ischemic stroke who received intravenous recombinant tissue plasminogen activator (rt-PA) after idarucizumab reversal were enrolled in the retrospective nationwide study. The clinical data, treatment course, and outcomes were recorded. Stroke severity was evaluated using the National Institutes of Health Stroke Scale (NIHSS) score. Any intracerebral hemorrhage (ICH) after rt-PA was detected by neuroimaging studies.<br />Results: Ten dabigatran-treated patients (6 men, mean age 71.10 ± 7.96 years) with acute ischemic stroke were included. Before stroke, the mean CHA <subscript>2</subscript> DS <subscript>2</subscript> -VASc score was 4.50 ± 1.57 and 8 patients (80%) received dabigatran 110 mg twice daily. All patients were treated with 5 g idarucizumab, following which the activated partial thromboplastin time normalized. Intravenous rt-PA (mean dose .78 mg/kg) was initiated a mean time of 11.11 minutes after idarucizumab infusion. The NIHSS score improved significantly after thrombolysis (16.0 ± 6.67 at admission to 9.38 ± 4.75 at discharge, P = .016). ICH developed in 3 patients (30%). Two of them were asymptomatic and 1 patient suffered from symptomatic ICH leading to mortality.<br />Conclusion: Our data reconfirmed the feasibility of intravenous rt-PA for Asian stroke patients after reversal of dabigatran effect with idarucizumab.<br /> (Copyright © 2018 National Stroke Association.
