Anticoagulation After Stroke Guidelines. In such patients a cardiac embolus most commonly originating from the left atrial appendage is a common cause of ischemic stroke. Adherence assessment and optimisation with anticoagulants are recommended for AF patients experiencing a TIA or stroke while taking warfarin or a DOAC. Patients who do not undergo PFO closure and have no other clear stroke etiology should be started on an antithrombotic though at this time it is unclear whether an antiplatelet or anticoagulation. Prospective observational studies and two small randomised trials have investigated the risks and benefits of early DOAC-administration initiation most with a median delay of 3-5 days in mild-to-moderate atrial fibrillation-associated ischaemic stroke.
Wait too long and theres a greater risk of a recurrent event. The ESCEHRA guidelines do not recommend anticoagulation with heparin low molecular weight heparin or a VKA immediately after an ischaemic stroke for AF patients. Adherence assessment and optimisation with anticoagulants are recommended for AF patients experiencing a TIA or stroke while taking warfarin or a DOAC. However a later treatment start might be considered for patients with haemorrhagic transformation. Aspirin plus clopidogrel is more effective than aspirin but less effective than anticoagulation for preventing stroke from atrial fibrillation. After stroke onset until start of oral anticoagulation with low molecular-weight heparins is not recommended by most guidelines whereas the UK guidelines recommend the use of aspirin 300 mgday before starting oral anticoagulant treatment.

In such patients a cardiac embolus most commonly originating from the left atrial appendage is a common cause of ischemic stroke. Timing of anticoagulation after recent ischaemic stroke in patients with atrial fibrillation. This guideline synopsis provides a moderate recommendation for PFO closure in patients younger than 60 years who do not have another identifiable cause of stroke after a comprehensive workup. A meta-analysis of randomized controlled trials. These guidelines recommend giving anticoagulants 4 days after stroke onset in patients with mild stroke not defined and small infarct size lesion 15 cm in the anterior or posterior circulation after 7 days in those with moderate stroke not defined and medium infarct size lesion in a cortical superficial branch of middle cerebral artery MCA in the MCA deep branch in the internal border zone. Patients who do not undergo PFO closure and have no other clear stroke etiology should be started on an antithrombotic though at this time it is unclear whether an antiplatelet or anticoagulation.
