Results:
A total of 132 NVAF patients were included in this study. The mean eGFR at readmission was significantly increased compared with the eGFR at baseline before the index ablation procedure (P < 0.01). The multivariable Cox regression analysis showed that a lower CHA2DS2-VASc score (HR: 0.416,P = 0.003) and paroxysmal recurrent atrial arrhythmia (HR: 2.965,P = 0.001) were associated with better renal function.
