The purpose of this study is to evaluate the antiinflammatory effects of rivaroxaban compared with dabigatran in patients with atrial fibrillation.
Previous study showed that administration of rivaroxaban reduced expression of proinflammatory mediators in apolipoprotein E-deficient mice. However, it is unknown whether the anti-inflammatory markers are decreased in patients with atrial fibrillation receiving novel oral anticoagulants.
