Abstract
For many years, anticoagulants have been used in the emergent treatment of patients with acute ischemic stroke. Anticoagulants are prescribed in an effort to prevent first or recurrent stroke, especially among patients with cardioembolism due to arterial fibrillation and large-artery atherosclerotic disease. Despite the widespread use, efficacy and safety of anticoagulants are controversial. Experts have given a broad spectrum of opinions. Surveys of practitioners have also demonstrated a lack of consensus on the use of anticoagulants for ischemic stroke. The uncertainty is due, in large part, to the lack of definitive clinical data. A review by the panel of the Stroke Council of the American Heart Association found no strong evidence for effectiveness of anticoagulants in treating acute ischemic stroke. Several clinical trials have suggested that utility of emergent anticoagulation has no significant effect in improving clinical outcomes for patients with acute ischemic stroke. In the present review, we have attempted to provide a framework for the emergent use of anticoagulants in acute ischemic stroke patients.
