AF after non-cardiac surgery increases stroke risk

US researchers say the findings suggest anticoagulation therapy may be needed postoperatively

Patients who develop AF following non-cardiac surgery have a significantly increased risk of transient ischemic attack (TIA) or stroke during the next five years, a study shows.
