New-onset atrial fibrillation at discharge in patients after coronary artery bypass surgery: short- and long-term morbidity and mortality

Abstract

A majority of NOAF patients revert to SR during the first months after surgery. On the other hand, 20-25% of NOAF patients develop chronic AF during long-term follow-up. Almost half of the NOAF patients were hospitalized during follow-up due to cardiovascular causes. Similarly, NOAF was associated with increased mortality due to cardiac causes, but not increased risk of stroke. This highlights the need for proper oral anticoagulation therapy in these patients.
