Usefulness of Anticoagulants in the Prevention of Ischemic Stroke

Oral anticoagulants are drugs commonly used in the prevention of vascular diseases, especially in embolic-type processes. Although several studies have assessed the possibility of using them in arterial processes, the experience has not been satisfactory so far. Heart diseases with major emboligenic flow are still the main indication, while the prevention of other low-risk heart diseases and treatment of large- or small-artery disease can be based on antiaggregant treatment. Other groups study the problem in large series.
