Cohort study confirms benefits of anticoagulation therapy in stroke prevention
Randomised controlled studies have shown that anticoagulation with adjusted warfarin dose consistently reduces stroke risk in patients with atrial fibrillation, yet the therapy is underused in mainstream clinical practice, says a study in this week's BMJ is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
