简要总结
The Biorhythm study aims to investigate the utility of new biomarkers (e.g. MR proANP, ST2) measured pre-procedure for the prediction of procedural success in patients with atrial fibrillation undergoing cardioversion or ablation.
详细描述
This is a prospective, observational, multicentre study of patients with paroxystic or persistent atrial fibrillation scheduled to undergo cardioversion or ablation of AF in routine practice. Serum levels of MR proANP and ST2 pre-procedure will be measured to attempt to identify a threshold that carries prognostic value for procedural success (maintenance of sinus rhythm at one year).
