In this retrospective study we analysed changes of the ST segment in patients with arterial hypertension using multi-lead body surface mapping of the electric heart field as the ST segment often shows non-specific changes and is influenced by many different conditions. We constructed isointegral maps (IIM) of chosen intervals (the first 35 ms, the first 80 ms, and the whole ST segment) in 42 patients with arterial hypertension (with and without left ventricular hypertrophy) and in the control group involving 23 healthy persons. We analysed the position and values of map extrema. Spatial distribution of voltage integrals was similar in the control group and in the “pure” hypertensives. Patients with the left ventricular hypertrophy exhibited shifts of the integral minima. Despite our expectations, the highest extrema values were found in the control group and not in the left ventricular hypertrophy group. The extrema values were similar in all hypertensives, with or without left ventricular hypertrophy. Differences could be explained neither by the influence of the age, nor by the body habitus.

Abstract: Objective: To investigate the significance of 24-hr ambulatory blood pressure monitoring (ABPM) data and metabolism indicators, as well their correlation in predicting the risk of left ventricular hypertrophy (LVH) in children and adolescents with arterial hypertension (AH). Methods: We studied 118 children and adolescents, M±m 15.51±0.25 yrs, Boys/Girls – 104/14, with AH: 60 stable, 40 labile, 18 prehypertension (high-normal blood pressure), and a control group of 13 normotensive children, M±m 15,19±0,41 yrs, Boys/Girls – 10/3. All patients underwent a comprehensive anamnestic, clinical, laboratory, and instrumental examination, including 24-hr ABPM; indicators were standardized by gender and age. On Doppler echocardiography (echoCG), the left ventricular myocardial mass index (LVMI) was calculated. Lipid spectrum parameters were determined by biochemical method, venous blood glycemia by GOD-PAP, blood serum basal immunoreactive insulin by ELISA methods, insulin resistance (IR) by HOMA parameters calculation. Statistical processing was performed using the package of statistical analysis software STATISTICA. Results: Of a range of metabolism indicators, BMI, TG level, LDL/HDL ratio, HOMA index, 24-hr DBP index, and the stable character of AH identified as the most significant factors in predicting the risk of LVH in hypertensive children. All multivariate models of logistic regressions, which include BMI, can predict the probability of LVH with an accuracy of 79.7-84.7%, sensitivity - 57.5-77.5%, specificity - 86.4-91.0%. Conclusions: Obtained satisfactory concordance of the actual data with predictive models' results indicate the possibility of their use to predict the risk of LVH in children and adolescents with AH.

Objective: Prehypertensive individuals are at increased risk for developing hypertension and their complication. Many studies show that 2/3 prehypertensive individuals develop hypertension after 4 years. ECG and echocardiography are the routine tests used to assess LV mass. The objective of the research to determine the percentage of change in left ventricular morphology in the ECG, echocardiography, which explore the characteristics of left ventricular structural changes by echocardiography in pre-hypertensive subjects. Materials and method: We studied a total of 50 prehypertensive, 30 males (60%) and 20 females (40%), mean age 48.20±8.47years. 50 normotensive volunteers as control participants. These subjects were examined for ECG and echocardiography. Results: In prehypertensive group, with 18% of left ventricular hypertrophy on electrocardiogram, 12% of left ventricular hypertrophy on echocardiography; in the control group, we did not find any subjects with left ventricular hypertrophy. In the group with left ventricular hypertrophy, mostly eccentric left ventricular hypertrophy (83.33%), concentric left ventricular hypertrophy is 16.67%. Restructuring of left ventricular concentric for 15.9% of subjects without left ventricular hypertrophy on echocardiography. Conclusion: There have been changed in left ventricular morphology even in prehypertensive
