Title: | Cardiovascular autonomic reflex tests and serum FGF21 levels in overweight and normal-weight men and women | Authors: | Jezdimirović, Tatjana Štajer, Valdemar Ostojić, Sergej |
Issue Date: | 2019 | Journal: | Archives of Physiology and Biochemistry | Abstract: | Objective: We evaluated cardiovascular autonomic reflexes and serum fibroblast growth factor 21 (FGF21), a surrogate marker of mitochondrial function, in a cohort of overweight and normal-weight adults (n = 42). Methods: Indices of autonomic function were monitored during supine rest, autonomic reflex tests and submaximal clinical exercise test, with heart rate variables and blood pressure measured with an automatic system. Results: Markers of sympathetic dominance were accentuated in overweight adults, including elevated resting low-frequency to the high-frequency ratio for heart rate variability (203 ± 227 vs. 96 ± 42; p =.01), and handgrip diastolic blood pressure (36 ± 15 mmHg vs. 25 ± 12 mmHg; p =.01). A weak non-significant trend has been found for a negative correlation between blood pressure responses to isometric handgrip test and FGF21 in the overweight group (r = −0.37; p =.09). Conclusions: Excess body weight appears to trigger sympathetic overactivity in overweight adults, yet autonomic dysregulation might not be associated with notable changes in serum FGF21. | URI: | https://open.uns.ac.rs/handle/123456789/10415 | ISSN: | 1381-3455 | DOI: | 10.1080/13813455.2019.1683586 |
