GW25-e0852 Pro- BNP in patients with pulmonary vein electrical isolation predicts the recurrence of late atrial fibrillation after ablation in paroxysmal and persistent atrial fibrillation

To determine the protective value of serum Pro-BNP in the recurrence of late atrial fibrillation after pulmonary vein isolation in paroxysmal and persistent atrial fibrillation. 94 patients in the present study had symptomatic paroxysmal AF and had failed to respond to at least one anti-arrhythmic
