| Summary: | The aim of the study was to study the associations of electrophysiological signs of metabolic disorders the myocardium (ECG phenomenon TV1>TV6 and components of the ECG of the of left ventricular hypertrophy phenomenon) with some lipid and non-lipid risk factors in an urban population of 25–44 years.
Material and methods. A population survey of a random sample of the
population aged 25–44 years (1439 people, 656 men, 783 women) in Novosibirsk was conducted. Blood concentrations of total cholesterol, high (HDL-C) and low density lipoprotein cholesterol (LDL-C), and triglycerides were measured. Systolic and diastolic blood pressure, body mass index, waist circumference, presence of arterial hypertension, smoking status were evaluated. The following ECG markers were analyzed: ECG phenomenon TV1>TV6 (the amplitude of T in V1 exceeds the amplitude of T in V6), components of the ECG of the of left ventricular hypertrophy phenomenon.
Results. ECG phenomenon TV1>TV6 was detected in 0.8 % of people (1.4 % of men, 0.2 % of women). In the general population among people with ECG phenomenon TV1>TV6, persons with triglyceride levels >150 mg/dl, with an increased body mass index/waist circumference, with arterial hypertension are 3.0, 2.0, 2.3 and 3.5 times more, respectively, than among people without ECG phenomenon TV1>TV6. Among men with ECG phenomenon TV1>TV6, persons with elevated triglyceride levels, with an increased body mass index/waist circumference, with arterial hypertension are 2.2, 1.5, 2.5 and 2.8 times more, respectively, than among men without ECG phenomenon TV1>TV6. The components of the ECG of the of left ventricular hypertrophy phenomenon were found in 1.4 % of people (2.1 % of men, 0.9 % of women). In the general population, among people with elevated triglyceride levels, with arterial hypertension, as well as in smokers – individuals with signs of left ventricular hypertrophy are 2.3, 2.1 and 1.7 times more, respectively, than without them. Among men with elevated blood levels of LDL-C, non-HDL-C, as well as smokers-individuals with components of the ECG of the of left ventricular hypertrophy phenomenon are 1.4, 1.4 and 1.6 times more, respectively.
Conclusions. ECG phenomenon TV1>TV6 and components of the ECG of
the of left ventricular hypertrophy phenomenon are associated with lipid and non-lipid risk factors for cardiovascular diseases, which indicates a potentiating effect of metabolic disorders in the body not only on the development of risk factors for cardiovascular diseases, but also metabolic disorders of the myocardium.
