Recurrent Ischemic #Stroke in Patients With Atrial #Fibrillation While Receiving Oral Anticoagulants

Importance  Patients with atrial fibrillation (AF) can have an ischemic stroke (IS) despite oral anticoagulant (OAC) treatment. Knowledge regarding the association between OAC discontinuation and the subsequent risk of recurrent IS in patients with AF is limited.Objectives  To determine the risk of recurrent IS in patients with AF receiving OAC and to evaluate the association between OAC… Continue reading Recurrent Ischemic #Stroke in Patients With Atrial #Fibrillation While Receiving Oral Anticoagulants

Early versus Later Anticoagulation for Stroke with Atrial Fibrillation

The effect of early as compared with later initiation of direct oral anticoagulants (DOACs) in persons with atrial fibrillation who have had an acute ischemic stroke is unclear.METHODSWe performed an investigator-initiated, open-label trial at 103 sites in 15 countries. Participants were randomly assigned in a 1:1 ratio to early anticoagulation (within 48 hours after a… Continue reading Early versus Later Anticoagulation for Stroke with Atrial Fibrillation

Smart thrombosis inhibitors without bleeding side effects via charge tunable ligand design

Current treatments to prevent thrombosis, namely anticoagulants and platelets antagonists, remain complicated by the persistent risk of bleeding. Improved therapeutic strategies that diminish this risk would have a huge clinical impact. Antithrombotic agents that neutralize and inhibit polyphosphate (polyP) can be a powerful approach towards such a goal. Here, we report a design concept towards… Continue reading Smart thrombosis inhibitors without bleeding side effects via charge tunable ligand design

Association of Oral #Anticoagulation With #Stroke in Atrial #Fibrillation or Heart #Failure: A Comparative Meta-Analysis

Atrial fibrillation and heart failure with reduced ejection fraction (HFrEF) are common sources of cardioembolism. While oral anticoagulation is strongly recommended for atrial fibrillation, there are marked variations in guideline recommendations for HFrEF due to uncertainty about net clinical benefit. This systematic review and meta-analysis evaluates the comparative association of oral anticoagulation with stroke and… Continue reading Association of Oral #Anticoagulation With #Stroke in Atrial #Fibrillation or Heart #Failure: A Comparative Meta-Analysis

Early initiation of prophylactic #anticoagulation for prevention of #coronavirus disease 2019 mortality in patients admitted to hospital in the United States: cohort study

To evaluate whether early initiation of prophylactic anticoagulation compared with no anticoagulation was associated with decreased risk of death among patients admitted to hospital with coronavirus disease 2019 (covid-19) in the United States. Design Observational cohort study. Setting Nationwide cohort of patients receiving care in the Department of Veterans Affairs, a large integrated national healthcare… Continue reading Early initiation of prophylactic #anticoagulation for prevention of #coronavirus disease 2019 mortality in patients admitted to hospital in the United States: cohort study

#Anticoagulation Timing in Cardioembolic #Stroke and Recurrent Event Risk

Guidelines recommend initiating anticoagulation within 4 to 14 days after cardioembolic stroke. Data supporting this did not account for key factors potentially affecting the decision to initiate anticoagulation, such as infarct size, hemorrhagic transformation, or high‐risk features on echocardiography.. ..We pooled data from stroke registries of 8 comprehensive stroke centers across the United States. We included… Continue reading #Anticoagulation Timing in Cardioembolic #Stroke and Recurrent Event Risk
