Low-intensity systemic inflammation is an important element of heart failure pathogenesis. The aim of this study is to assess proinflammatory status serum indicators (C-reactive protein (CRP), tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6)) in middle-aged males (M) and females (F) with essential hypertension (HTN) depending on left ventricular (LV) diastolic dysfunction (LVDD). The main group comprised 55 M and 49 F with the first- to second-severity grade HTN with mild heart failure and a preserved LV ejection fraction ≥50%. Patients had sinus rhythm, first or second-severity degree LVDD, LV hypertrophy, left atrium dilatation, and NT-proBNP > 125 pg/mL. Comparison group: 30 hypertensives without cardiac dysfunction; control group: 31 normotensives. Quantitative features were compared using the Mann–Whitney test, median χ², ANOVA module. Spearman’s rank correlation coefficients were determined to identify the relationship between the proinflammatory pattern and exercise tolerance. Hypertensive M had markedly higher CRP, TNF-α, and IL-6 levels compared to F. All mean values corresponded to reference range. In patients with second-degree LVDD, CRP, TNF-α, and IL-6 levels were significantly greater than in subjects with first-degree LVDD (both within M and within F samples). Significant negative associations between CRP, IL-6, and TNF-α levels and the 6 min walk test existed in hypertensive M and F. The study demonstrated a close relationship between the proinflammatory pattern and LVDD and exercise tolerance indicators, regardless of the hypertensive patient’s sex.

The aim of this research was to correlate indicators of proinflammatory status and the structural/functional characteristics of the cardiovascular system comparatively in male and female patients with essential hypertension (EH) complicated by diastolic chronic heart failure (CHF) with preserved left ventricular ejection fraction (LVEF). The study included 104 middle-aged patients (55 males (M) and 49 females (F)) with first- or second-degree EH complicated by CHF with preserved LVEF. They all belonged to the low functional class of CHF, with LVEF ≥50%, first- or second-degree of LV diastolic dysfunction (LVDD), LV hypertrophy (LVH), and dilatation of the left atrium (LA) with a sinus rhythm and N-terminal brain natriuretic peptide >125 pg/mL. Serum levels of C-reactive protein (CRP), tumor necrosis factor alpha (TNF-α), and interleukin-6 (IL-6) were measured. To identify the relationship between the proinflammatory pattern and cardiovascular parameters, Spearman’s rank correlation coefficients were determined. M had markedly higher levels of CRP, TNF-α, and IL-6 compared to F. However, all the mean values corresponded to the reference range. Significant direct associations of CRP level with the LV mass index (LVMI), relative wall thickness (RWT), LA volume index (LAVI), E/e’ ratio, and systolic and diastolic blood pressure (SBP, DBP) existed in both M and F, as well as negative correlations of CRP with LVDD parameter e’ and distance covered in a 6 min walk test. M and F had a positive association between IL-6 and LVMI, LAVI, E/e’ ratio, SBP, RWT, and DBP, as well as strong negative associations between IL-6 and e’ and distance passed in 6 min in each group. Significant direct correlations existed between serum TNF-α level and LVMI, RWT, LAVI, E/e’, SBP, and DBP both in M and F. Furthermore, there were negative relationships of TNF-α level with e’ and the distance covered for the 6 min walk. This study demonstrated a close relationship between the blood levels of proinflammatory autacoids and indicators of EH, exercise tolerance, LVH, LVDD, and LA enlargement, regardless of the patient’s sex. Compared to female patients, male patients had stronger correlations of CRP, TNF-α, and IL-6 levels with indicators of LVDD degree.

Left ventricular hypertrophy (LVH) is the most important element of cardiovascular continuum in patients with essential hypertension (EH). The results of a five-year retrospective analysis of EH patients cohort with initially different types of left ventricular geometry (491 subjects) are presented. It is shown that the overall mortality in patients with concentric and eccentric LVH does not differ significantly (37 and 35 %, respectively) but exceeds that in subjects with normal LV geometry (20 %). Associated and concomitant pathology determine the total and cardiovascular prognosis more in patients with concentric LVH than in subjects with eccentric LVH. The presence of ECG valid quantitative and strain diagnostic LVH criteria (Sokolow-Lyon index and Perugian university sign) determines the worst remote prognosis in patients with both concentric and eccentric LVH. The enlarged size of the left atrium is an universal marker of poor outcome in hypertensive patients regardless the type оf left ventricular geometry.

Left ventricular hypertrophy (LVH) is one of the cardio-vascular continuum components, determining the prognosis of patient with essential hypertension (EH). Pathogenesis of LVH has a multifactor character. Important role in development of cardiomyocites hypertrophy, Intracardiac fibrosis, left ventricle cavity dilation belongs to renin-angiotensin-aldosteron system (RAAS). Pharmacologic blockade of RAAS composes the basis of therapy, directed to LVH regress. Application of Telmisartan is considered high-reasonable approach to treatment of EH-patient with LVH.
