Abstract

Heart failure (HF) has a significant effect on the prognosis of the patients with atrial fibrillation (AF), and also it is an important risk factor for overall mortality. High molecular weight fibroblast growth factor-2 (Hi-FGF-2) is emerging as a prognostic marker with HF and AF. The aim of this study was to prove that Hi-FGF-2 would predict occurrence of HF in the patients with AF. Subjects diagnosed with paroxysmal AF (Group paAF), persistent AF (Group peAF) and sinus rhythm (Group SR) were enrolled in the study. Serum Hi-FGF-2 concentration was measured by ELISA at baseline. Multivariable logistic models and receiver operating characteristic (ROC) curve analysis were established to predict the prognosis of AF subjects. 260 patients were enrolled in the study: 104 (40.0%) admitted for sinus rhythm (Group SR) and 156 (60.0%) with AF (Group paAF and Group peAF). The Hi-FGF-2 levels were much lower in the Group SR (58.2 ± 27.1 ng/L) than in the Group AF. Furthermore, the Group peAF (84.3 ± 34.1 ng/L) had higher Hi-FGF-2 levels than the Group paAF (72.9 ± 35.8 ng/L). Serum Hi-FGF-2 levels were classified into trisection in the multivariable logistic model (T1 < 57.3 ng/L, 57.3 < T2 < 86.5 ng/L, and T3 > 86.5 ng/L). Hi-FGF-2 showed good predictive ability for new-onset HF in the patients with AF. The occurrence of HF was associated significantly with increased tertile of serum Hi-FGF-2 levels (T2: OR 5.922, 95% CI 1.109-31.626, P = 0.037 and T3: OR 8.262, 95% CI 1.735-39.343, P = 0.008). ROC curve analysis showed that the area under curves for Hi-FGF-2 were 0.720 (P < 0.0001). Hi-FGF-2 has a significant meaning in AF subjects. Further to this, higher circulating Hi-FGF-2 was highly related to persistent AF, and Hi-FGF-2 may be an independent risk factor of occurrence HF in AF subjects.
