Asymmetric dimethylarginine concentration and recurrence of atrial tachyarrythmias after catheter ablation in patients with persistent atrial fibrillation

Purpose It has been reported that elevation of asymmetric dimethylarginine (ADMA) concentration is involved in atrial fibrillation (AF) process. The purpose of this study was to determine whether ADMA concentration is related to recurrences of AF after catheter ablation.
