Key result
Adipokine links to LVH vary across preclinical HF stages for leptin versus adiponectin.
Why the study?
The association of left ventricular hypertrophy and metabolic risks with adipokine levels across different stages of heart failure remains debatable in obesity.
Does the level of circulating adipokines correlate with left ventricular hypertrophy in obese patients at preclinical stages of heart failure?

Does the level of circulating adipokines correlate with left ventricular hypertrophy in obese patients at preclinical stages of heart failure?
The study highlights that the relationship between adipokines and cardiac remodeling changes depending on the preclinical stage of heart failure, indicating complex metabolic-structural interactions in obesity.
Stage-specific adipokine-LVH associations in obese patients may guide biomarker interpretation; leaves open prospective validation before clinical adoption.
Introduction . Association of left ventricular hypertrophy (LVH) in obesity and accompanying metabolic risks with adipokines levels at the different stage of heart failure (HF) is still debatable. The aim of study was to investigate the relationship of circulating adipokines levels with LVH in obese patients at preclinical stage of HF. Materials and methods . The study included 74 obese patients: 43% had no markers of LVH (stage A HF, group 1); 57% had LVH (stage B HF, group 2). Transthoracic echocardiography, laboratory assessment of N-terminal fragment of the brain natriuretic peptide, soluble suppression of tumorigenesis-2 (sST2), circulating leptin and adiponectin levels, homeostasis model assessment of insulin resistance (IR) (HOMA-IR) were done. Matched-pairs analysis was applied. Results . Negative correlations of LVH with leptin levels in group 1 (stage A HF) and with adiponectin levels in group 2 (stage B HF) were detected (all p < 0.05). Positive correlations of the sST2 / adiponectin ratio and HOMA-IR with the parameters of LVH were detected in group 2 (all p >< 0.05). Conclusion. The direction of the associations between circulating adipokines and LVH varies with the preclinical stage of HF. The data obtained may reflect a relationship between heart remodeling in response to molecular mechanisms of inflammation and IR in obese patients at the certain stage of cardiovascular continuum.

Positive correlations of the sST2 / adiponectin ratio and HOMA-IR with the parameters of LVH were detected in group 2 (all p ˂ 0.05). Conclusion . The direction of the associations between circulating adipokines and LVH varies with the preclinical stage of HF. The data obtained may reflect a relationship between heart remodeling in response to molecular mechanisms of inflammation and IR in obese patients at the certain stage of cardiovascular continuum.

Lyasnikova et al. (2022) conducted a cross-sectional in obese patients in preclinical heart failure (n=74). Circulating adipokines (leptin and adiponectin) was evaluated on Correlation between circulating adipokine levels and left ventricular hypertrophy parameters (p=<0.05). The direction of the associations between circulating adipokines and left ventricular hypertrophy varies with the preclinical stage of heart failure, showing negative correlations with leptin in stage A and with adiponectin in stage B (all p<0.05).
