title: New oral anticoagulants for stroke prevention in atrial fibrillation: more choices bring more challenges.
abstract: For patients with atrial fibrillation, anticoagulant therapy is essential to reduce the risk of ischemic stroke that is associated with this arrhythmia. Historically, warfarin has been the preferred treatment for patients at moderate to high risk despite many potential limitations. With the development of newer oral anticoagulants, clinicians now have 3 additional options: dabigatran, rivaroxaban, and apixaban. Although these agents clearly offer some advantages over warfarin, they may not be appropriate for all patients. This article will discuss factors that should be considered when selecting among these various anticoagulants.
