POAF may not associate with differences in gender-based survival .

These limitations notwithstanding, this ROOBY-FS 10-year investigation shows that patients who
experience postoperative atrial fibrillation after CABG are more likely to have 10-year atrial fibrillation and
reduced survival at the time of long-term follow-up. At the time of discharge, patients with POAF may
benefit from counsel to alert them that it is possible their AF may persist or recur and that assessment and
counsel on the risk-benefit ratio of long-term anticoagulation may ultimately be necessary. Patients with
POAF who have higher rates of co-morbidities may benefit from prospective studies to determine whether
more frequent monitoring and sustained management of these associated health issues could reduce their
long-term risk of atrial fibrillation and death.
