Warfarin may raise hemorrhagic stroke risk without ischemic benefit in older HD patients with AF; leaves open net benefit and requires randomized trials.
Does warfarin initiation affect the risk of hemorrhagic or ischemic stroke in older hemodialysis patients with incident atrial fibrillation?
In older hemodialysis patients with incident atrial fibrillation, warfarin initiation is associated with an increased risk of hemorrhagic stroke without a significant reduction in ischemic stroke.
