Relationship between circulating fibroblast growth factor-23 and incidence of atrial fibrillation

Objective To investigate whether the concentration of circulating fibroblast growth factor 23 (FGF-23) is associated with new-onset atrial fibrillation (NAF) in general populations without chronic kidney disease (CKD).Methods A total of 1152 health checkup examinees who were free of CKD and atrial arrhythmia were selected between January 2012 and December 2015.Serum intact FGF-23 concentrations were measured using the Kainos 2-site ELISA method.NAF was diagnosed according to ECGs and hospital discharge records.All the subjects were followed up for three years.Multivariate logistic regression analysis was used to estimate the association between FGF-23 and NAF.Results The average age of these subjects was 56.6±5.7 years.44.2% (509) of them were males and 35 of them (3.0%) developed NAF during follow-up.These subjects were divided into four groups according to their FGF-23 levels.Elder males were more likely to have higher levels of FGF-23,who tended to have higher BMI,lower eGFR and higher serum phosphorus and PTH levels,and were more vulnerable to hypertension,diabetes mellitus,coronary artery disease,and left ventricular hypertrophy (LVH)(P<0.05).According to multivariable analysis,a higher baseline FGF-23 level was found to be associated with the risk of NAF (P<0.05).Conclusions Higher serum FGF-23 concentrations are associated with NAF in general populations without CKD.
