“…Нарушение нейроэндокринных влияний с развитием энергетического и электролитного дефицита сердечной мышцы и тканевой гипоксии лежит в основе этой патологии [8][9][10][11]. ЭКГ также является одним из самых изученных и широко применяемых методов диагностики, позволяющих выявлять нарушения проводимости, косвенные признаки гипертрофии отделов сердца и другие неспецифические электрофизиологические признаки метаболических нарушений миокарда [12,13].…”

Aim. To study ischemic and/or nonspecific ECG signs of metabolic changes in the myocardium and to determine their relationship with unfavorable cardiovascular prognosis in a 7-year prospective observation of young people under 45 years of age.Material and methods. A cross-sectional population survey of a random sample aged 25-44 years (n=1363) was conducted in Novosibirsk. The survey program used the standardized epidemiological Rose questionnaire. Biochemical tests were used to measure blood concentrations of total cholesterol (C), triglycerides (TG), low- and high-density lipoprotein cholesterol (LDL-C, HDL-C), and fasting blood plasma glucose. Systolic and diastolic BP (SBP, DBP), the presence of arterial hypertension (AH), body mass index (BMI), waist circumference (WC), and smoking status were assessed. ECG was recorded at rest in 12 standard leads followed by interpretation according to the Minnesota Code. The presence of ischemic and/or nonspecific ECG signs of metabolic changes in the myocardium was determined. Subjects with ECG signs of ischemic changes in the myocardium were selected for long-term follow-up and additional examination by cardiologists. Then the whole cohort was monitored for 7 years, and cardiovascular events were recorded, including using data from the WHO Myocardial Infarction Registry in Novosibirsk. For statistical analysis of the results, cardiovascular events were combined into a composite endpoint.Results. During 7 years, 40 people (27 men and 13 women) had an unfavorable cardiovascular prognosis. Multivariate regression analysis showed that a 7-year unfavorable cardiovascular prognosis in people younger than 45 years was associated with signs of ischemic myocardial alterations identified on the background ECG (OR 5.319, 95% CI: 1.543-18.342, p=0.008) and nonspecific ECG signs of metabolic changes in the myocardium (OR 2.978, 95% CI: 1.216-7.216, p=0.017) regardless of age, gender, the presence of arterial hypertension (AH) and type 2 diabetes mellitus (DM2).Conclusion. In young people under 45 years of age, not only ECG signs of ischemic changes in the myocardium, but also nonspecific ECG signs of metabolic changes in the myocardium are associated with an unfavorable cardiovascular prognosis, directly and independently on age and gender, in a long-term, 7-year period.

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. AbstractAim. 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.
