What is the optimal timing for initiation of anticoagulation for patients with AF presenting with an acute stroke or ICH?
The optimal timing for initiation of anticoagulation for patients with AF presenting with an acute stroke or ICH is within 24 hours of symptom onset for ICH, and within 48 hours for ischemic stroke. For patients with ICH, it is recommended to start anticoagulation with either warfarin or a non-vitamin K antagonist oral anticoagulant (NOAC). For patients with ischemic stroke, it is recommended to start anticoagulation with a NOAC unless there is a contraindication, in which case warfarin should be started.
