SCORE2 (Systematic COronary Risk Evaluation 2) is a risk assessment scale for cardiovascular events, presented in 2021 by the European Society of Cardiology. Both for training and validation of the SCORE2 model, representative samples from the Russian population were not used. Therefore, we aimed to validate SCORE2 on a such sample. For this purpose, we used a sample from the ESSE-RF epidemiological study consisting of 7251 participants aged 40-69 years without history of CVDs. We performed the validation by comparing SCORE2 risk estimates for ESSE-RF participants with the observed incidence of cardiovascular events in the study, adjusted for event information losses. The validation demonstrated that SCORE2 risk estimates were accurate for Russian men and inaccurate for Russian women. Together with the quantitative assessment of risk, SCORE2 offers its interpretation in terms of 10-year CVD risk group: low-moderate, high, and very high. For Russian men we considered the original interpretation of the SCORE2 estimates to be questionable because almost none of the men would be categorized as having "low-to-moderate" 10-year CVD risk. This problem would be typical for all countries of the very high CVD risk region. Therefore, we proposed a new interpretation of the SCORE2 risk estimates for men from the very high risk region. According to the proposed interpretation, the fraction of men in ESSE-RF in "low-to-moderate" 10-year CVD risk increased from 2% to 18% and the fraction of men in "very high" CVD risk decreased from 63% to 20% as compared to the original interpretation. The proposed interpretation would allow a more personalized approach to CVD treatment and optimize the burden on primary healthcare in the very high risk region countries., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Svinin et al.

Objective: To compare the frequency and healthfulness of foods being advertised to children and adolescents in four countries of WHO European region., Design: Cross-sectional quantitative study, guided by an adapted version of the WHO protocol. All recorded food advertisements were categorised by categories and as either 'permitted' or 'not permitted' for advertising to children in accordance with WHO Regional Office for Europe Nutrient Profile Model., Settings: Four countries: Russia, Turkey, Kazakhstan and Kyrgyzstan., Participants: TV channels most popular among children and adolescents., Results: Analysis included 70 d of TV broadcasting for all channels, during which time there were 28 399 advertisements. The mean number of advertisements per hour varied from eleven in Turkey and Kazakhstan to eight and two in Russia and Kyrgyzstan. In all countries, the majority of the food and beverages advertised should not be permitted for advertising to children according to the WHO Nutrient Profile Model. The mean number of non-permitted food and beverage advertisements per hour was high in Turkey and Kazakhstan (8·8 and 8·5 ads) compared with Russia (5·1) and Kyrgyzstan (1·9). Turkey was the only country where nutritional information was fully available, and no values were missing that prevented coding for some product categories., Conclusions: Results revealed that children and adolescents in four countries are exposed to a considerable volume of food and beverage advertisements, including sugary products on broadcast television. As such, policymakers should consider protecting youth by developing regulations to restrict these marketing activities within media popular with children.

Objectives: Our study evaluated the impact of a wide range of characteristics of large administrative regions on the individual level of cigarette smoking in the Russian adult population. Methods: The pool of participants included 20,303 individuals aged 25-64 years. We applied 64 characteristics of the 12 Russian regions under study for 2010-2014. Using principal component analysis, we deduced five evidence-based composite indices of the regions. We applied the generalized estimating equation to determine associations between the regional indices and the individual level of smoking. Results: The increased Industrial index in the region is associated with the probability of smoking (odds ratio = 1.15; 95% confidence interval = 1.06-1.24). The other indices show associations with smoking only in separate gender and educational groups. Surprisingly, it was found that the Economic index has no associations with the probability of smoking. Conclusion: We evaluated the key associations of the territorial indices with the individual probability of smoking, as well as the mutual influence between the territorial indices and individual factors., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Maksimov, Shalnova, Balanova, Kutsenko, Evstifeeva, Imaeva and Drapkina.)

Currently, in the epidemiology of nutrition, methodological approaches to the empirical assessment of the diets of the population and their relationship to health indicators are actively using. In Russia, these approaches have been used in a number of cohort and regional studies, however, such studies are not available for the entire Russian population. Aim . Identification of empirical dietary patterns in the Russian population and analysis of their associations with risk factors for chronic non-communicable diseases. Material and methods . The work was carried out as part of a multicenter epidemiological study "Epidemiology of cardiovascular diseases in the regions of the Russian Federation" (ECVD-RF) in 2013-2014. The final sample size was 19 520 people aged 25- 64 years. Arterial hypertension, general and abdominal obesity, hypercholesterolemia, hypertriglyceridemia, low HDL, high LDL, and hyperglycemia were observed as risk factors for chronic non-infectious diseases. The data on the frequency of consumption of 13 food groups, which were grouped into 10 groups by combining dairy products into one were collected by interviewing. The identification of dietary patterns and assessment of their sustainability was performed using factor analysis (principal component analysis). In accordance with the individual commitment of the participants to the selected dietary patterns the sample was grouped into quartiles for each of the patterns. In order to ensure associations between patterns commitment and risk factors, a logistic regression analysis was used adjusted for the socio-demographic characteristics of the participants. Results and discussion . Four stable dietary patterns with a total specific gravity of the explained variance of 55.9% were identified and conventionally designated as "Reasonable" (milk, sweets and confectionery, fresh fruits and vegetables, cereals and pasta), "Salt" (sausages, pickles and pickled products), "Meat" (meat, fish and seafood, poultry meat) and "Mixed" (beans, pickles and pickled products, fish and seafood). The set of products of the "Reasonable" patterns mainly corresponds to the "Healthy" or "Balanced" patterns in foreign studies, the combination of the "Salt" and "Meat" patterns - the "Western Salt". Adherence to a "Reasonable" pattern was associated with a decrease in the likelihood of risk factors for chronic non-communicable diseases, and to a "Salt" and "Meat" patterns, on the contrary, with an increase. The associations obtained generally correspond to the results of similar foreign studies. A "Mixed" dietary pattern was associated with a few risk factors, which did not allow an unambiguous assessment of the pattern in terms of its impact on health. Conclusion . The study identified empirical dietary patterns of the Russian population and characterized them in terms of associations with the state of health of risk factors for chronic non-communicable diseases., Competing Interests: The authors declare no overt and potential conflict of interest related to the publication of this article., (Copyright© GEOTAR-Media Publishing Group.)

Aim: to study associations between elevated blood plasma concentration of N-terminal pro-brain natriuretic peptide (NT-proBNP), risk factors and cardiovascular diseases (CVD) in samples of adult population of Russian Federation (RF) aged 25-64 years., Materials and Methods: We analyzed data of examination of representative samples of population of 5 regions of RF obtained within the framework of the multicenter ESSE-RF study (2012-2013). Number of examined subjects was 8 077 (3 176 men). Methods included use of standard questionnaire, measurements of height, body mass, blood pressure (BP), and plasma NT-proBNP level. The following CVD were included into analysis: arterial hypertension (AH), ischemic heart disease (IHD), atrial fibrillation (AF), and stroke., Results: Women compared to men had higher NT-proBNT concentration was higher in women compared to men, in both genders it rose with age. Overall 17.9 % of examinees had elevated NT-proBNT levels (14.2 and 20.3 % among men and women, respectively). Elevated NTproBNP level was associated in men with age, myocardial infarction, angina pectoris, ischemic ECG changes, left ventricular hypertrophy, AF, bradycardia, smoking, in women with age, IHD, ischemic ECG changes, AF, bradycardia, heart rate ≥80 bpm, BP ≥160/95 mm Hg., Conclusion: In studied RF population elevated NT-proBNP level was significantly associated with gender, age, smoking, and CVD.

Modeling is the common approach for predicting not only the population health, but also the social and economic burden of disease, which is an important argument while making decisions in health care and prevention., Aim: To develop the model for predicting cardiovascular risk, applicable for the assessment of clinical and socio-economic effects of preventive and therapeutic actions at the level of the whole population or part (region, city, group of patients)., Material and Methods: An analytical model for making decision was performed by using a Markov model consisting of Markov states and probabilities of transition from one state to another within a certain time interval. The model included risk factors and cardiovascular diseases (blood pressure, cholesterol, smoking) and probabilities of transition between them. Data was standardized by age for both males and females. Multivariate sensitivity analysis was performed. The literature search conducted using eLIBRARY.RU (http://elibrary.ru) and CyberLeninka (http://cyberleninka.ru). Consultations with experts in the field of coronary heart disease, stroke, heart failure were carried out., Results: The model, allowing to compare the outcomes of two scenarios (absence/presence of intervention). The model included risk factors: arterial hypertension, smoking, hypercholesterolemia, and important CVD: coronary artery disease, myocardial infarction, unstable angina, heart failure, chronic heart failure after myocardial infarction, transient ischemic attack, stroke, atrial fibrillation. There was absorbent state - death. At the output from the model the patient state was defined as the sum of the Markov states characteristics during the model time horizon. Each result had the cost and outcome, which values could be calculated by simulation modeling ("cohort simulation"). The data analysis from prospective study had shown that mortality increases with age, as expected, but in different age groups impact of cardiovascular causes was different and declined with age. In the case of the blood pressure there was the expected increase of the death risk with the growth of pressure levels, both for males and females, except for males 60-64 years old who had a minimal risk of death at the blood pressure 140-149/90-99 mmHg, and among males with normal blood pressure the risk was higher. Smoking was associated with an expected increase of the death risk among all age groups in both sexes. In males, aged 40-64 years, the death risk was higher at the normal levels of cholesterol (2-5 mmol/l), than at the cholesterol levels equal 5-7 mmol/l. There were no data sources to assess probability of occurrence of the risk factors (hypertension, smoking, hypercholesterolemia) in patients who did not have these factors previously in our studies, and available literature. This requires the prospective studies on at least two slices of surveys (not just with the endpoint analysis). Analysis of the literature on search of prospective Russian studies that would evaluate the probability of transition from one state to another, and consultations with experts have identified that currently conducted studies do not provide all the necessary probability of transition on the basis of national data. In the absence of local data for the model is acceptable to use the results of meta-analyzes of international studies., Conclusion: Markov model will allow for prediction the effectiveness of different interventions, including their socio-economic consequences. The created model will allow in the future to make changes with the appearance of the results of new studies or new data in order to improve modeling accuracy.

Aims: Inflammatory reaction after stent implantation is associated with in-stent restenosis (ISR). We assessed the association of optical coherence tomography (OCT) features of neointima with systemic levels of high-sensitivity C-reactive protein (hs-CRP) and eosinophil cationic protein (ECP) measured at the time of ISR detection., Methods and Results: Patients presenting with symptomatic angiographically documented ISR (diameter stenosis ≥ 50% by visual estimation) were included. Quantitative OCT analysis included the measurement of minimal lumen diameter, minimal luminal area, stent and neointimal area, stent and restenosis length, restenotic tissue burden, and symmetry ratio. Qualitative OCT analysis included the assessment of ISR plaque type, neointimal tissue structure, lumen shape, presence of microvessels and calcific nodules. At the time of ISR detection hs-CRP and ECP levels were measured, and statistical analysis was performed using as cut-off 3 mg/L and 4.5 µg/L, respectively. Our population included 40 patients, 24 bare metal stents and 16 drug-eluting stents. Patients with high hs-CRP levels had a higher restenostic tissue symmetry ratio (0.56 ± 0.17 vs. 0.42 ± 0.13, P = 0.01) when compared with patients with low hs-CRP levels. Patients with high ECP levels had a higher neointimal burden (70 ± 14 vs. 64 ± 11, P = 0.05) in comparison with patients with low ECP levels., Conclusions: Inflammatory biomarkers assessed at the time of ISR detection are associated with different aspects of neointimal tissue. While hs-CRP seems to have a role in neointimal tissue shape, ECP is related to a neointimal burden., (Published on behalf of the European Society of Cardiology.

The aim of this study was to assess the involvement of eosinophil cationic protein, a marker of eosinophil activation, in the development of in-stent restenosis after drug-eluting stent implantation. Follow-up angiography at 6 to 12 months was performed in 32 patients who were treated with percutaneous coronary intervention and implantation of sirolimus-eluting stents. Blood plasma levels of eosinophil cationic protein (ECP) and total immunoglobulin E (IgE) were measured by enzyme-linked immunosorbent assay and the level of C-reactive protein (hs-CRP) by high-sensitivity nephelometry. According to angiography data, in-stent restenosis occurred in 13 patients, while 19 patients did not develop it. There were no differences between the hs-CRP and IgE levels in patients with or without restenosis. In contrast, ECP level was higher in patients with restenosis compared with that in patients without restenosis [17.7 ng/mL (11.2-24.0) vs. 9.0 ng/mL (6.4-12.9), p = 0.017]. The incidence of in-stent restenoses was 63% in patients with ECP level higher than or equal to 11 ng/mL, and 19% in patients with an ECP level lower than 11 ng/mL (p = 0.019). These findings suggest that elevated eosinophil activation may play an important role in the pathogenesis of in-stent restenosis after implantation of drug-eluting stents.
