Aim. To assess the indigenous small population of the Shor people in terms of the ethnic-specific development of cardiovascular diseases and their risk factors during the epidemiological studies in the Mountain Shoria. Methods. The study was carried included the indigenous and non-indigenous population of the Mountain Shoria during two different time periods: the first period (19982002) 1215 people (550 indigenous Shors and 665 non-indigenous people) and the second period (20132017) 1409 people (901 and 508, respectively). The prevalence of cardiovascular risk factors, arterial hypertension (AH) and ischemic heart disease (CHD) was studied. In the second period of the study, the genotype frequencies of the genes ACE (I/D, r 4340), AGT (c.803TC, rs699), AGTR1 (A1166C, rs5186), ADRB1 (c.145AG, Ser49Gly, rs1801252), ADRA2B (I/D, rs28365031), MTHFR (c.677CT, Ala222Val, rs1801133) and NOS3 (VNTR, 4b/4a) and their associations with arterial hypertension were identified. There was data on organ damage obtained among patients with high blood pressure (left ventricular myocardial hypertrophia, carotid arteries intima-media complex thickening, albumin level). Results. The first period of the studies showed that the Shors differed from the incoming population in an extremely low prevalence of lipid metabolism disorders, obesity, and an almost complete absence of diabetes mellitus. At the same time, there was a high prevalence of tobacco smoking and alcohol consumption. The second period of the studies demonstrated significant differences between different ethnic cohorts according to the genetic passport towards a more favorable profile among the indigenous people. However, the Shor people with arterial hypertension had a more severe course of hypertensive disease, defined as frequent organ damage. In addition, the profile of a patient with coronary heart disease differed depending on the place of residence, in urban or rural. Epidemiological studies contribute to the acquisition of new knowledge about different ethnic groups, their lifestyles and agricultural practices, regions of residence, and the features of candidate gene polymorphism. This provides valuable material for individualizing the prevention and treatment of diseases. Conclusion. Ethnicity makes adjustments to the patient's profile; understanding the ethnic specificity allows developing targeted preventive measures, thereby preserving the peoples health.

Aim.Objective assessment of cardiovascular risk (CVR) in patients with arterial hypertension (AH), who first contact with primary care setting.Material and methods. 300 patients (age 40-65 years) with sustained increase in arterial pressure and first seek medical attention were included in the study. All patients underwent medical examination, history taking to identify risk factors, blood pressure measurement and anthropometric research, biochemical blood assay to estimate levels of total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, glucose. Based on the specified parameters, the risk was determined by SCORE (Systematic Coronary Risk Evaluation). After the risk assessment, all patients underwent an echo-cardiography, duplex ultrasonography screening of the brachiocephalic arteries and determination of microalbuminuria to detect target organ damage. According to results of a complex survey, the risk was reclassified based on the presence of target organ damage.Results.The study showed that patients with sustained AH who first seek medical attention have a large number of risk factors and their combinations, among which the most common are dyslipidemia (89,3%), smoking (37,7%) and obesity (28,3%). Patients with AH who first seek medical attention without clinical signs of atherosclerosis often have various disorders of target organs, such as left ventricular hypertrophy — 67,3%, thickening of carotid intima-media complex — 46,3%, atherosclerotic plaques in carotid arteries — 34,7%, microalbuminuria — 25,3%, as well as different combinations thereof. After a complex examination, the CVR profile of patients changes increases. According to SCORE 60% of patients with low and mean risk is reclassified to high risk.Conclusion.One of the most important tasks of health care system in Russia is to increase the efficiency of the CVR stratification systems, as well as to develop a new standards of examination of patients with AH on an outpatient stage, in order to reduce cardiovascular morbidity and mortality.

Epidemiological studies in cardiology often are confronted with the need of modeling the population dependence of the development of cardiovascular diseases (CVD) on a complex of influencing risk factors (RF). A method for assessment the CVD population risk is proposed, the calculation of which assumes the population group as the unit of analysis, and the prevalence of risk factors in this group as the input data. Calculation of the population risk is build taking into account predictive value of risk factors basing on their contribution to CVD prevalence. The method of calculation of population risk, examples of its application (arterial hypertension in working population, ethnic groups, ischemic heart disease in open and working population), as well as discussion of its strong and weak sides are presented in this review.

Aim: to investigate relationship between arterial hypertension (AH) and risk factors / subclinical damage of target organs in patients with type 2 diabetes mellitus (DM2). Methods. We included into this clinical epidemiological study 528 patients with DM2 (30.5 % men, 69.5 % women; mean age 54.1±0.3 years; 80.3 % with AH, 19.7 % without AH), who answered questions of the ARIC study questionnaire related to risk factors. Also, we studied features of target organ damage and laboratory indicators. Results. In comparison with normotensives patients with AH more frequently had ischemic heart disease (12.7±1.6 % vs. 5.8±2.3 %, p<0.05), chronic heart failure (CHF) (30.9±2.2 % vs. 9.6±2.9 %, p<0.001), atherosclerosis of vessels of lower extremities (69.8±2.2 % vs. 53.8±4.9 %, p<0.01) and cerebral vessels (50.9±2.4 % vs. 28.8±4.4 %, p<0.001), history of stroke (5.0±1.1 % vs. 0 %, p<0.05), hypertonic angiopathy (14.5±1.8 % vs. 6.5±2.5 %, p<0.05), low level of high density lipoprotein (87.3±2.2 % vs. 74.5±6.4 %, p<0.05), electro- and echocardiographic signs of left ventricular hypertrophy (75.6±2.1 % vs. 45.4±5.1 %, p<0.001; 61.1±2.6 % vs. 24.4±4.7 %, p<0.001, respectively), lowering of left ventricular ejection fraction (12.5±1.7 % vs. 7.8±2.8 %, p<0.001), diastolic disfunction of the left ventricle (52.6±2.7 % vs. 23.2±4.7 %, p<0.001), atherosclerosis of the aorta (38.0±2.6 % vs. 20.7±4.5 %, p<0.01), lowering of the ankle-brachial index (left – 29.8±2.3 % vs. 14.9±3.5 %, p<0.01; right – 31.5±2.3 % vs. 9.9±3.0 %, p<0.001, respectively), increased intima-media thickness of the right carotid artery (84.6±5.0 % vs. 60.0±11.0 %, p<0.05). Conclusion. In patients with type 2 diabetes and AH, in order to develop strategy of macro- and microvascular complications prevention, it is necessary to conduct early screening of risk factors and subclinical damage of target organs.

Introduction. The problem of high mortality from cardiovascular diseases is caused, among other things, by asymptomatic atherosclerosis, which proceeds latently for a long time and manifests itself as a serious vascular catastrophe, which is of particular importance for people working at production facilities with difficult and dangerous working conditions.The aim of the study was to assess the risk factors for atherosclerosis and the state of the vascular wall in the workers of the main professions of coal enterprises in the South of Kuzbass.Material and methods. In total, the study included 384 people (men), of whom 266 were the workers in coal mines in the South of Kuzbass and 118 people who were not employed in the coal industry, aged 40 to 55 years. The diagnosis of atherosclerosis was carried out on the ultrasound system “Vivid E9” of the manufacturing company GE using a linear sensor for measuring the thickness of the intima-media complex and visualization of atherosclerotic plaques. To identify significant risk factors, anthropometric, anamnestic data, indices of lipid and carbohydrate metabolism, and the presence of arterial hypertension were studied.Results. Significant differences in the frequency of asymptomatic atherosclerosis in the form of an increase in intima-media thickness by more than 1 mm and / or the presence of atherosclerotic plaques in both groups were not found: 60.2% among the miners and 62.3% among non-coal mining workers (p=0.703); at the same time, the percentage of detection of atherosclerotic plaques in arteries was significantly lower among coal workers — 46.9% versus 60.5% among people in the comparison group (p=0.016). The common risk factors for all examined subjects were arterial hypertension and increased level of glycated hemoglobin; in turn, in coal miners additional risk factors were increased values of low density lipoproteins and waist-hip index, as well as burdened heredity for cardiovascular diseases, and among the individuals not employed in the coal industry it was smoking.Conclusions. The most significant risk factors for atherosclerosis in coal industry workers were arterial hypertension, raised values of glycated hemoglobin, low density lipoproteins and waist-hip index, as well as burdened heredity for cardiovascular diseases. Significant differences in the frequency of asymptomatic atherosclerosis in the form of an increase in the thickness of the intima-media complex of the main arteries and the presence of atherosclerotic plaques in both groups were not established, but the percentage of the detection of atherosclerotic plaques was lower among coal miners.The authors declare no conflict of interests.

Left bundle branch block is not a benign pathology, and its presence requires the identification of a pathological substrate, such as ischemic heart disease. Left bundle branch block appears to be more commonly associated with normal coronary arteries, especially in women. The objectives of our study were to describe the particularities of left bundle branch block in women compared to men with ischemic heart disease. Result: We included seventy patients with left bundle branch block and ischemic heart disease, with a mean age of 67.01 ± 8.89 years. There were no differences in the profile of risk factors, except for smoking and uric acid. The ventricular depolarization (QRS) duration was longer in men than women (136.86 ± 8.32 vs. 132.57 ± 9.19 msec; p = 0.018) and also men were observed to have larger left ventricular diameters. Left bundle branch block duration was directly associated with ventricular diameters and indirectly associated with left ventricular ejection fraction value, especially in women (R = −0.52, p = 0.0012 vs. R = −0.50, p = 0.002). In angiography, 80% of women had normal epicardial arteries compared with 65.7% of men; all these patients presented with microvascular dysfunction. Conclusion: The differences between the sexes were not so obvious in terms of the presence of risk factors; instead, there were differences in electrocardiographic, echocardiographic, and angiographic aspects. Left bundle branch block appears to be a marker of microvascular angina and systolic dysfunction, especially in women.

Abstract Background The aim of the study was to assess the relationship between the occurrence of rheumatoid arthritis (RA) and ankylosing spondylitis (AS) and the cardiac magnetic resonance (CMR) changes in people without clinically overt heart disease. Methods The study group consisted of 74 people (48.81 ± 11.35 years): 29 patients with RA, 23 patients with AS and 22 people from control group. Blood samples were taken to assess laboratory parameters, disease activity was determined using activity scales, and CMR was performed. Results It was shown that the factors independently related to higher left ventricular mass index are AS occurrence, human B27 leukocyte antigen occurrence, higher neutrophil gelatinase–associated lipocalin concentration (NGAL) and higher body mass index (BMI). The lower right ventricular ejection fraction is result of an independent effect of RA, AS and higher NGAL. RA presence, methotrexate use, higher rheumatoid factor titer, higher NGAL, older age and higher BMI should be considered independent risk factors for greater left ventricular myocardium water content. RA occurrence, AS occurrence, type 2 diabetes occurrence and a higher C-reactive protein concentration can be independently associated with a higher probability of non-ischemic left ventricular myocardium injury. Larger pericardial fluid volume is result of an independent effect of higher NGAL, higher anti-cyclic citrullinated peptide antibodies titer and higher DAS28 disease activity index. Use of steroids is protective factor against larger volume of pericardial fluid. Conclusions RA and AS in people without clinically apparent heart disease are associated with the occurrence of adverse changes in CMR. Key Points•RA and AS in people without clinically apparent heart disease are associated with the occurrence of adverse changes in CMR..•The independent risk factors for higher LVEF are AS occurrence, human B27 leukocyte antigen occurrence, higher NGAL concentration and higher BMI..•RA presence, methotrexate use, higher RF, higher NGAL, older age and higher BMI are independent risk factors for higher LV T2 ratio..•RA occurrence, AS occurrence, type 2 diabetes occurrence and a higher CRP are independently associated with a higher risk of non-ischemic LV myocardium injury..
