    BackgroundSeveral clinical trials have tested the potential utility of emergent anticoagulation for acute ischemic stroke.Summary Of ReviewRather than performing a meta-analysis that combines the data from several trials, this review focuses on individual studies. Although these trials do have inherent limitations, they demonstrate that emergent use of an anticoagulant is associated with a modest but significantly increased risk of hemorrhagic transformation of the ischemic stroke or serious nonneurological bleeding. The trials do not demonstrate a benefit from emergent anticoagulation in improving outcome, reducing mortality, and preventing early recurrent stroke.ConclusionsThese results suggest that most patients with acute stroke should not be treated with unfractionated heparin or other rapidly acting anticoagulants after stroke. Prevention of deep vein thrombosis and pulmonary embolism among bedridden patients is the only established indication for early anticoagulation after acute ischemic stroke.
