  • Title: Warfarin Reinitiation After Intracranial Hemorrhage: A Case Series of Heart Valve Patients.
    Author: Wan A, Butcher K, Hodgson M, Schultz K, Bungard TJ.
    Journal: Can J Neurol Sci; 2020 Mar; 47(2):237-241. PubMed ID: 31796141.
    Abstract:
    Patients with mechanical heart valves are at high thrombotic risk and require warfarin. Among those developing intracranial hemorrhage, limited data are available to guide clinicians with antithrombotic reinitiation. This 13-patient case series of warfarin-associated intracranial hemorrhages found the time to reinitiate antithrombotic therapy (17 days, interquartile range 21.5 days), and changes to international normalized ratio targets were variable and neither correlated with the type, location, or etiology of bleed, nor the valve and associated thromboembolic risk. The initial presentation significantly impacted prognosis, and diligent assessment and follow-up may support positive long-term outcomes.
