Circulating leptin and adiponectin levels, as well as sST2/adiponectin ratio and HOMA-IR, significantly correlated with left ventricular hypertrophy in preclinical heart failure (all p<0.05).
Observational (n=74)
The association between circulating adipokines and left ventricular hypertrophy in obese patients varies depending on the preclinical stage of heart failure, reflecting potential molecular mechanisms of inflammation and insulin resistance.
p-value: p=<0.05
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.
Lyasnikova et al. (Wed,) conducted a observational in Obesity and preclinical heart failure (n=74). Circulating adipokines (leptin, adiponectin) and insulin resistance was evaluated on Correlation with left ventricular hypertrophy (LVH) (p=<0.05). Circulating leptin and adiponectin levels, as well as sST2/adiponectin ratio and HOMA-IR, significantly correlated with left ventricular hypertrophy in preclinical heart failure (all p<0.05).
