Methods:
We retrospectively recruited non-valvular AF (NVAF) patients with mildly
impaired renal function admitted for catheter ablation and readmitted
due to recurrence of AF. The estimated glomerular filtration rate (eGFR)
was calculated before the index procedure and during readmission.△ eGFR was defined as the difference between eGFRreadmission and eGFRbaseline.
The same calculation applied for△ CHA2DS2-VASc score. The primary
endpoint was improved renal function (△ eGFR > 0)
after AF catheter ablation in patients with atrial arrhythmia
recurrence.
