Abstract
PURPOSE
The hormone fibroblast growth factor 21 (FGF-21) regulates carbohydrate and lipid homeostasis. FGF-21 represents an attractive novel therapy for obesity since administration of FGF-21 has been shown to improve metabolic abnormalities in obese animal models. We investigated FGF-21 and its relationship with epicardial fat thickness (EFT), metabolic parameters, and inflammatory markers in premenopausal obese women compared to controls with similar Systematic Coronary Risk Evaluation (SCORE) project risk profiles.
METHODS
Forty-five obese premenopausal women with body mass index (BMI) ≥30 kg/m(2) and 41 control premenopausal women with BMI <25 kg/m(2) with similar SCORE project risk profiles were included in this case-control study. EFT was evaluated by two-dimensional transthoracic echocardiography. Serum FGF-21 was measured with an ELISA kit.
RESULTS
FGF-21 and EFT were significantly higher in obese women compared to controls (p < 0.001). Multiple stepwise linear regression analysis showed that EFT, BMI, and triglycerides (TG) independently contributed to FGF-21 (R(2) = 0.757, p < 0.001). However, homeostasis model assessment of insulin resistance (HOMA-IR), visceral ectopic fat, and inflammatory markers were not found as a direct contributor to serum FGF-21 level (p > 0.05).
CONCLUSIONS
EFT, BMI, and TG may play an important role in predicting serum FGF-21 level which may be a potential therapeutic target in cardiometabolic disorders in the future.
