Abstrakt: Background: Renal dysfunction has been identified as a risk factor for both stroke and bleeding events in atrial fibrillation (AF) patients, yet the mechanisms remain unclear. We examines the connection between fine fibrillatory wave and estimated glomerular filtration rate (eGFR) decline, alongside chronic kidney disease (CKD).
Methods: Persistent AF patients admitted to Jinan University's First Affiliated Hospital from January 2019 to June 2023 were enrolled. Kaplan-Meier analysis explored kidney endpoints for coarse and fine fibrillatory wave. A multivariate Cox model estimated adjusted hazard ratios (HR) and 95 % confidence intervals (95 % CI) to determine the correlation between fine fibrillatory wave and eGFR decline, as well as CKD.
Results: Of the 3521 AF patients, 229 were ultimately included in the analysis of this study. The median age of these patients was 75 years, with 58 % being male. The median follow-up time was 23 months, and the mean eGFR was 70 ± 19 mL/min/1.73 m 2 . Multivariate COX regression analysis revealed fine fibrillatory wave (HR = 8.311, 95 % CI 3.418-20.211, p < 0.001) as an independent risk factor associated with a ≥ 30 % decline in eGFR. Among 166 AF patients with eGFR >60 mL/min/1.73 m 2 , 40 cases (24 %) experienced a decline to <60 mL/min/1.73 m 2 . In comparison to coarse fibrillatory wave, the risk of fine fibrillatory wave causing eGFR decline to <60 mL/min/1.73 m 2 was approximately 4.6 times higher (HR = 4.645, 95 % CI 2.127-10.142, p<0.001).
Conclusions: Fine fibrillatory wave was independently associated with the risk of eGFR decline ≥30 % and eGFR decline to <60 mL/min/1.73 m 2 .
