Safety of Intravenous Thrombolysis for Acute Ischemic Stroke in Patients Taking Warfarin with Subtherapeutic INR
Current guidelines allow the administration of intravenous recombinant tissue plasminogen activator (IV r-tPA) to warfarin-treated patients with acute ischemic stroke (AIS) who have an international normalized ratio (INR) of ≤1.7. However, concerns remain about the safety of using IV r-tPA in this situation due to a conceivable risk of symptomatic intracranial hemorrhage (sICH), lack of dedicated randomized controlled trials and the conflicts in the available data. We aimed to determine the risk of sICH in warfarin-tr eated patients with subtherapeutic INR who received IV r-tPA for AIS in our large volume comprehensive center.
