To assess the prevalence of chronic stress in the adult population in the Vladimir region, taking into account sex characteristics.Material and methods. This cross-sectional population study was performed in five cities of the Vladimir Oblast (Vladimir, Kovrov, Murom, Yuryev-Polsky and Vyazniki) from May 2018 to March 2020. From six health care facilities, 9 therapeutic areas were selected. Then, from the assigned population aged 30-69 years, respondents from each area were invited to the study. To identify chronic stress, the Reeder questionnaire was used, which makes it possible to identify three types of disorders: low, moderate and severe stress. The study analyzed fully completed Reeder L. chronic stress questionnaires from 1081 respondents (393 men and 688 women).Results. Among men, every second person has a low chronic stress, 42% — moderate stress, while high chronic stress was found in 6.4% of cases. A similar trend is observed among women. High levels of chronic stress were detected in 8% of women, and the gap between the prevalence of low and moderate chronic stress was minimal. In general, the prevalence of various levels of chronic stress between men and women was comparable, without significant differences. Sex variability in the prevalence of chronic stress was revealed in various cities of the Vladimir Oblast. In Vladimir, the prevalence of high stress among men was three times higher than in women, while in Vyazniki and Kovrov the opposite pattern was observed. In the other two cities (Murom and Yuryev Polsky), the prevalence of high chronic stress between men and women was comparable.Conclusion. In the working-age population, a high chronic stress level is detected in up to 10%. In some cities, there are sex differences between men and women. The mean level of chronic stress is determined in 42-43% of cases. The results obtained indicate the need for large-scale preventive measures to combat chronic stress among working-age men and women of in the Vladimir Oblast.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139318545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of course, the social side was predominant before the development of evidencebased medicine. But in the modern context, the development of the humanities and social sciences, as well as neuroscience and psychology, makes it possible to take into account the biographical narrative of the patient’s personality as an integral part of the doctor-patient relationship. At the intersection of \"biological\" and \"biographical\" in the disease nature there are a number of factors, such as loneliness, stress, emotions, that reify, enact a person’s social self into somatic pathology or somatic health. The problem of combining humanities and natural science knowledge is very complex due to the fundamental difference in the methods of study, but for modern medicine such a connection is absolutely necessary.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139320154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the epidemiological profile and long-term prognostic significance of atrial fibrillation (AF) as a risk factor for adverse clinical outcomes in patients with dilated cardiomyopathy (DCM).Material and methods. The study included 270 patients with DCM (206/76,3% men, age 47 [37; 56] years, left ventricular (LV) ejection fraction 29 [21; 35]%). The observation period was 6 years (Me 76 [57; 119] months). To assess the effect of AF on DCM prognosis, Kaplan-Meier curves and Cox regression of clinical outcomes, including cardiovascular death, heart transplantation, and ventricular assist device implantation, were analyzed.Results. Of 270 patients with DCM, paroxysmal AF was detected in 10 (3,7%) patients (initial, 5/1,85%; during the first follow-up year, 5/1,85%). After 5 years, another 65 (24,1%) individuals had AF (paroxysmal, persistent or permanent). Ventricular tachyarrhythmias were registered in 163 (60,4%) patients. Compared with patients maintaining sinus rhythm, patients with AF were older (51,4±10 vs  43,6±13 years, p=0,001) and had lower exercise tolerance (6-minute walk test: 379±45 vs 445±43 meters; p=0,0002) and a higher heart failure functional class (NYHA class III-IV: 38/50,7% vs 52/26,7%; χ2=13,6; p=0 ,0003). In patients with AF, initially more pronounced manifestations of right ventricular contractile dysfunction (TAPSE: 13,1±3,4 vs 15,5±4,6 mm; p=0,0001) and LV diastolic dysfunction (E/A: 2,9±1,5 vs 2,1±1,3; p=0,006; E/e' 15,6±6,9 vs 11,8±7,2; p=0,019), more dilated left atrium (left atrial volume index: 63,3±19 vs 50±18,7 ml/m2; p=0,006). During the 6-year median follow-up, AF was observed in 75 patients (0,46 new cases/100 patients/year). As a result of Cox regression analysis, AF as a time-dependent factor was identified as an independent predictor of cardiovascular death (hazard ratio 3,99; 95% confidence interval, 1,67-8,59; p=0,0001).Conclusion. AF, as one of the most common sustained atrial tachyarrhythmias in the population, demonstrated a lower prevalence (27,8%) in the DCM cohort compared to ventricular tachyarrhythmias (60,4%), but a high prognostic significance of the negative impact on the risk of fatal outcomes. The development of AF in patients with DCM is associated with a 4-fold increase in cardiovascular death risk over a 6-year period.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":"125 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess the incidence of myocarditis in patients with primary myocardial hypertrophy and to study its contribution to the disease course.Material and methods. The study included 100 patients with primary left ventricular myocardial hypertrophy, 52 men and 48 women (mean age, 51,5±15,7 years; followup period 10,4 [2,1; 36,1] months). All patients underwent electrocardiography, 24-hour electrocardiographic monitoring, echocardiography, as well as DNA analysis (n=96), myocardium pathological study (n=29), cardiac magnetic resonance imaging (n=31), cardiac multislice computed tomography (n=26), assessment of anti-cardiac antibodies (n=43), free light chain level in serum and urine by immunofixation method (n=10); 99mTc-pyrophosphate myocardial scintigraphy (n=5); biopsy of the rectal mucosa and/or subcutaneous fat for amyloid (n=9).Results. In 68%, true (sarcomeric) hypertrophic cardiomyopathy (HCM) was diagnosed, in 16% — amyloidosis with cardiac involvement, in 10% — storage diseases, in 3% — neuromuscular diseases, in 2% — myocardial hypertrophy was combined with severe restriction (mixed phenotype), and in 1% — LEOPARD syndrome. Concomitant myocarditis was diagnosed in 30% of patients. In HCM, myocarditis was detected in 31% of cases. These patients had a significantly higher heart failure class (heart failure class 3 [2; 3] vs 2 [1; 3], p=0,026) and mortality (33,3% vs 6,4%, p=0,01). In amyloidosis, the incidence of myocarditis was 31,3%. In these patients, ventricular tachycardia was observed significantly more often: 80,0% vs 18,2% (p=0,036). The prevalence of concomitant myocarditis in the subgroup of storage diseases was 30%: 2 patients with Fabry disease and 1 patient with Danon disease. Of the three patients with neuromuscular diseases, myocarditis was diagnosed in 1. In the subgroups with the restrictive phenotype and LEOPARD syndrome, no cases of myocarditis were recorded. Treatment of myocarditis made it possible to stabilize the patients' condition.Conclusion. Concomitant myocarditis led to heart failure progression, worsening ventricular arrhythmias and, as a consequence, an increased risk of sudden cardiac death. It is necessary to actively diagnose and treat myocarditis in patients with primary myocardial hypertrophy.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study included 120 male patients (mean age, 67±5 years) with multivessel coronary artery disease after elective CABG surgery. According to the type of coronary artery involvement, patients were divided into groups of diffuse (n=77) and focal (n=43) atherosclerosis. In peripheral blood samples, the content of the main fractions of lipoproteins, including Lp(a), was determined. Activation of neutrophil granulocytes upon addition of Lp(a) was assessed in whole blood and in primary cell culture.Results. In patients with diffuse coronary stenosis, there was a tendency to higher Lp(a) levels; no changes in other lipid profile parameters were detected. In this group of patients, an increase in the absolute leukocyte count was noted due to neutrophilic granulocytes. An absolute neutrophil count >2,9 million/mL was associated with diffuse disease (AUC, 0,69 (95% confidence interval (CI) 0,600,77), p=0,0002, sensitivity 85%, specificity 42%). In patients with Lp(a) ³30 mg/dL, the diagnostic value of a neutrophil count >2,9 million/mL for diffuse stenosis was higher (AUC, 0,74 (95% CI 0,60-0,86), p= 0,005, sensitivity 90%, specificity 48%). According to logistic regression analysis with the introduction of neutrophils and conventional risk factors (age, body mass index, hypertension and smoking) into the model, only the number of neutrophils above the threshold level remained an independent factor in diffuse coronary stenosis. Lp(a) can induce neutrophil activation, detected by increased CD66b overexpression in whole blood, as well as the formation of neutrophil extracellular traps in primary cell culture.Conclusion. Neutrophil granulocytes can participate in the formation of diffuse atherosclerotic coronary lesions. One of the neutrophil activators may be Lp(a). The combination of high neutrophil count and Lp(a) level in the blood increases the risk of diffuse coronary atherosclerosis.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were divided into groups depending on HFpEF presence: group 1 (n=63) included patients with newly diagnosed HFpEF, and group 2 included patients without heart failure (n=20). Serum catestatin concentrations were 43,1% lower (p<0,001) in patients with HFpEF than in patients without it. Catestatin had a negative correlation with levels of N-terminal pro-brain natriuretic peptide and C-reactive protein. Moreover, serum catestatin values were inversely correlated with LV remodeling parameters, whereas no relationship was found with HRV values.

We performed anthropometry with assessment of body height and weight, chest circumference, body surface area, body mass index (BMI), Pignet index, Erisman index, grip and back strength test. Echocardiography, cycle ergometry with assessment of physical working capacity (PWC170) and maximum oxygen consumption (MOC). The relationship between traits was assessed using the Spearman rank correlation coefficient (rs). Critical significance level was p=0,05.Results. According to echocardiography, qualified athletes had significant differences in structural parameters. Group II was characterized by an increase in left ventricular (LV) volumetric dimensions and identified correlations of BMI and body surface area with end-diastolic dimension (r=0,602), end-diastolic volume (r=0,591), end-systolic volume (ESV) (r=0,429), stroke volume (r=0,597), PWC170 (r=0,550). Groups I and III were characterized by an increase in LV posterior wall (LVPWT) and interventricular septal (IVST) thickness. In group I, there was a relationship between body surface area and LVPWT (r=0,413); Pignet index with MOC (r=0,623); PWC170 with Erisman index (r=0,573), strength of the right (r=0,610) and left hand (r=0,515), back muscles (r=0,445).

To assess the association between pathological ascending aortic (AA) wall changes and its planimetric characteristics in non-syndromic non-familial (sporadic) aneurysm and dilation of the AA.Material and methods. The study included 174 patients with sporadic aneurysms and dilation of the AA, who underwent elective surgery between January 2010 and July 2015 and were divided into 2 groups: patients with AA aneurysm (AAA) (AA diameter >50 mm) and tricuspid aortic valve (AV) with significant aortic stenosis (AS) or regurgitation (AR) (AAA group, n=120), and persons with borderline AA dilatation (AA diameter 45-50 mm), associated with a bicuspid aortic valve (BAV) and significant AS (BD group, n=54). Standard paraclinical investigations and pathological examination of the VA wall were used. Statistical processing was carried out in the SPYDER 4.1.5 environment (Python 3.8), and included univariate correlation analysis, logistic regression analysis, as well as supervised machine learning (ML) methods (support vector machine, k-nearest neighbor method, random forest).Results. Logistic regression revealed positive associations between AA atherosclerosis and age, cystic medial necrosis (CMN) and sinus of Valsalva (SV) diameters. The support vector machine method demonstrated a tendency towards AA expansion at the SV level in individuals with CMN (accuracy, 60,5%), as well as towards expansion of the tubular AA in atherosclerosis (accuracy, 79,2%). During the random forest analysis, the first stage was to construct decision trees to predict three following outcomes: the presence of CMN, atherosclerosis, or normal aortic structure. The model accuracy was 64,2%. Next, the variables \"CMN\" and \"atherosclerosis\" were combined, and prediction was made for the outcomes \"normal AA wall structure\" and \"pathological AA wall structure\". The model accuracy was 73,5%.Conclusion. The use of ML opens up new opportunities for predicting aortopathy and a patient-centered approach to treatment. In AR, a more aggressive AA intervention is warranted. To predict aortopathies, thoracic aorta diameters indexed to body surface area should not be used. Aortic wall sampling (circular section) followed by a continuous pathological examination may be promising.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":"161 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
