Therapeutic behavior of primary care physicians in patients with atrial fibrillation taking vitamin K antagonists not adequately controlled

Published:January 27, 2016DOI:https://doi.org/10.1016/j.ejim.2016.01.016
      In the majority of patients with atrial fibrillation (AF), long-term oral anticoagulation is necessary to reduce the risk of stroke. Although effective, vitamin K antagonists (VKAs) exhibit many limitations [
