Correlation of FGF2 with other HF parameters. (a) Circulating levels of FGF2 in healthy controls (n = 36) and HF cases with ejection fraction (EF) < 45% (n = 16) and EF > 45% (n = 64). (b) Expression levels of FGF2 according to New York Heart Association cardiac function classification. (c) Expression levels of FGF2 in different HF types. (d) Expression levels of FGF2 in groups with different HF etiologies. ** p < 0.01; *** p < 0.001. Abbreviations: FGF2, fibroblast growth factor 2; HF, heart failure; HFrEF, heart failure with reduced ejection fraction; HFmrEF, heart failure with mildly reduced ejection fraction; HFpEF, heart failure with preserved ejection fraction
