A fibrilação atrial se consolidou nas últimas décadas como um grave problema de saúde pública, considerando o seu notório aumento de prevalência com o envelhecimento aliado ao aumento da sobrevida da população. Dados do Framingham Heart Study indicam que, mesmo em um cenário ótimo de ausência dos clássicos fatores de risco para sua ocorrência, como tabagismo, consumo abusivo de álcool, obesidade, hipertensão, diabetes e cardiopatia, cerca de 10% dos indivíduos com idade igual ou superior a 80 anos e algo em torno de 25% daqueles com idade igual ou superior a 90 anos terão fibrilação atrial1. Essas taxas aumentam substancialmente quando se agregam a fatores de risco isolados ou combinados. A despeito da sua já bem conhecida relação com a ocorrência do acidente vascular encefálico trombo-embólico2, a presença de fibrilação atrial tem sido identificada como um fator de risco de mortalidade independente em grandes estudos populacionais3.

Abstract Background Data on the optimal treatment strategy for antiarrhythmic drug therapy (AAD) after atrial fibrillation (AF) catheter ablation are inconsistent. While AAD potentially stabilizes sinus rhythm, it also increases the patients' treatment burden. Methods Patients from the prospective German Ablation Registry (n=3275) discharged with or without AAD after AF catheter ablation were compared regarding long-term success, cardiovascular events and patient reported outcome. Results In patients with paroxysmal AF (n=2138) recurrence and rehospitalization rates did not differ when discharged with (n=1051) or without (n=1087) AAD (recurrence: adjusted odds ratio (OR) 1.13, 95% confidence interval (CI) [0.95–1.35]; rehospitalization: OR 1.08, 95% CI [0.90–1.30]). The reablation rate was higher and reduced treatment satisfaction was reported more often in those discharged with AAD (reablation: OR 1.30, 95% CI [1.05–1.61]; reduced treatment satisfaction: OR 1.76, 95% CI [1.20–2.58]). Similar rates of recurrences, rehospitalisations, reablations and treatment satisfaction were found in patients with persistent AF (n=1137) discharged with (n=641) or without (n=496) AAD (recurrence: OR 1.22, 95% CI [0.95–1.56]; rehospitalization: OR 1.16, 95% CI [0.90–1.50]; reablation: OR 1.21, 95% CI [0.91–1.61]; treatment satisfaction: OR 1.24, 95% CI [0.74–2.08]). The incidence of cardiovascular events and mortality did not differ at follow-up in paroxysmal and persistent AF patients discharged with or without AAD. Conclusion The rates of recurrences, cardiovascular events and mortality did not differ between patients discharged with or without AAD after AF catheter ablation. However, AAD should be considered carefully in patients with paroxysmal AF, in whom it was associated with a higher reablation rate and reduced treatment satisfaction.
