Abstract

BACKGROUND: Catheter ablation for atrial fibrillation is a clinically established treatment by now while success rate varies between 60% and 85%. Interventional treatment of atrial fibrillation is still a challenging technique associated with a long procedure time and risk of major complications in up to 6 % of treated patients. The aim of this study was to investigate the predictive value of plasma brain natriuretic peptide (BNP) in patients undergoing pulmonary vein isolation concerning stable sinus rhythm after ablation.

METHODS: In 68 consecutive patients with atrial fibrillation (AF) and normal left ventricular ejection fraction, BNP was measured at baseline before pulmonary vein isolation (PVI). All patients received a 7-days-holter monitoring 3 months after radiofrequency (RF) ablation in order to detect recurrent AF episodes.

RESULTS: 48 patients with paroxysmal and 20 patients with persistent AF were enrolled. Baseline BNP was significantly higher in patients with persistent AF compared to patients with paroxysmal AF (145,5 pg/ml vs. 84,4 pg/ml; p<0,05). 3 months after PVI 38 patients (79,1%) with paroxysmal AF had a stable sinus rhythm documented on 7-days-holter monitoring, where as in 10 patients (20,9%) AF episodes were detected. Patients with a successful PVI showed significantly lower BNP plasma levels at baseline compared to patients with AF recurrrence (68,7 pg/ml vs. 144,1 pg/ml; p<0,05). In patients with persistent AF 55% (11 cases) had no recurrence of AF at 3 months 7-days holter and in 9 patients (45%) AF recurred. BNP plasma levels at baseline were lower in patients with stable sinusrhythm after 3 months compared to the group of recurrent AF (105,8 pg/ml vs. 193,3 pg/ml; p=0,11).

CONCLUSIONS: Patients with AF and low preprocedural BNP plasma levels showed a better outcome after PVI. Thus BNP may be helpful in patient selection for a successful treatment of AF by PVI.
