Withdrawal Versus Continuation of Amiodarone in Successfully Treated Patients With Persistent Atrial Fibrillation — WISDOM  

Persistent Atrial Fibrillation Clinical Trial

Official title:
Withdrawal of Amiodarone Treatment Versus Continuation in Successfully Treated Patients With Persistent Atrial Fibrillation. A Randomized Study.

Clinical Trial Summary

Amiodarone is considered to be the most effective antiarrhythmic drug in the prevention of persistent atrial fibrillation. It can however cause many adverse events, both cardiac and non-cardiac. Long-term maintenance of sinus rhythm after cardioversion is difficult especially because of high recurrence rates during the first month after cardioversion. Duration of atrial fibrillation, type of underlying disease, left ventricular function, left atrial size and age are associated with maintaining sinus rhythm. Early recurrence of atrial fibrillation may be related to a highly arrhythmogenic period due to recovery from electrical remodelling. Late recurrences may be related to other triggers than recovery from electrical remodelling. In this study the investigators want to investigate the effect of amiodarone withdrawal on the occurrence of late relapses of persistent atrial fibrillation. Furthermore, the investigators want to investigate the effect of amiodarone withdrawal on the occurrence of amiodarone related adverse events as well as adverse events related to atrial fibrillation or underlying heart disease. The investigators also want to investigate which patients characteristics are and potential triggers have a prognostic value in the occurence of late relapses after amiodarone withdrawal.
