RELATIONSHIP BETWEEN BIOMOLECULES ASSOCIATED WITH THE SECRETORY ACTIVITY OF VISCERAL ADIPOCYTES AND ELECTROPHYSIOLOGICAL SIGNS OF METABOLIC CARDIOMYOPATHIES IN PERSONS UNDER 45 YEARS OF AGE

Highlights ECG signs of metabolic cardiomyopathies in men aged 25–44 years, regardless of age and waist circumference, are directly associated with the serum adipsin concentration and inversely associated with the concentration of glucagon-like peptide 1 in the blood. ECG signs of metabolic cardiomyopathies in women aged 25–44 years are directly associated with the serum c-peptide concentration and inversely associated with the concentration of glucose-dependent insulinotropic polypeptide 1 in the blood. Abstract Aim . To study the relationship between electrophysiological signs of metabolic cardiomyopathy (MC) and biomolecules associated with the secretory activity of visceral adipocytes in persons aged 25–44 years residing in Novosibirsk. Methods. The study included 1 198 subjects. A single-stage survey of a random sample of the 25–44-year-old population of Novosibirsk (49,7% men, 50,3% women) was conducted. During the examination, among other things, a resting 12-lead ECGs was recorded, and later the ECGs were classified according to Minnesota Code categories. Five ECG signs of MC were analysed: 1) ST-segment displaced above baseline (ST-segment elevation); 2) ST-segment displaced below baseline (ST-segment depression); 3) T wave changes; 4) TV1>TV6 patterns and 5) ECG signs of left ventricular hypertrophy. Serum concentrations of biomolecules associated with the secretory activity of visceral adipocytes were determined by multiplex analysis. Results . The results of multivariate logistic regression analysis showed that the ECG signs of MC in men aged 25–44 years, regardless of age and waist circumference, are directly associated with the serum adipsin concentration (Exp B 1,039, 95% CI 1,002–1,077, p = 0.039) and inversely associated with the concentration of glucagon-like peptide 1 in the blood (Exp B 0.999, 95% CI 0.998–1,000, p = 0.042). ECG signs of MC in women aged 25–44 years are directly associated with the serum peptide concentration (Exp B 1,439, 95% CI 1,082–1,915, p = 0.012) and inversely associated with the concentration of glucose-dependent insulinotropic polypeptide in the blood (Exp B 0.986, 95% CI 0.978–0.995, p = 0.001). Conclusion . The results obtained reflect the significant influence of these biomolecules associated with the secretory activity of visceral adipocytes on the occurrence of ECG signs of MC in young people aged 25–44 years.
