To evaluate the role of growth differentiation factor-15 (GDF-15) in long-term prognosis in patients with uncomplicated myocardial infarction (MI). Material and methods . The study included 118 patients with uncomplicated ST-elevation and non-ST-elevation MI. In addition to the routine examination, all patients were analyzed for GDF-15, as well as the N-terminal pro-brain natriuretic peptide (NT-proBNP) by enzyme immunoassay in the first 48 hours from the onset of MI symptoms. The changes in the patients' condition were assessed by questioning after 1, 3, 6, 12 months, as well as the analysis of medical records in the event of repeated cardiovascular events and deaths. The endpoints were cardiovascular death, hospitalization for recurrent MI, and/or unstable angina. To assess the value of quantitative variables in predicting recurrent cardiovascular events, the ROC analysis was used. The survival function of patients was assessed using the Kaplan-Meier method. Results. Twelve-month follow-up revealed 29 recurrent cardiovascular events, including 2 deaths and 8 recurrent MIs. GDF-15 was predictive of recurrent cardiovascular events with a sensitivity of 77,3% and a specificity of 56,2% (ROCAUC, 0,7±0,065 (95% confidence interval (CI), 0,572-0,827), p=0,004). Patients with GDF-15 ≥2,075 ng/mL had a higher risk of recurrent cardiovascular events (hazard ratio (HR), 3,4 (95% CI, 1,342-8,613), p=0,005). Another prognostic factor influencing the rate of recurrent cardiovascular events was NT-proBNP. An NTproBNP level ≥578 pg/mL was associated with an increased risk of cardiovascular death and rehospitalization for unstable angina and recurrent MI (HR, 4,3 (95% CI 1,828-10,239), p=0,00019). Conclusion . The combined increase in GDF-15 ≥2,075 ng/mL and NT-proBNP ≥578 pg/mL in patients with uncomplicated MI increases the risk of recurrent cardiovascular events over the next 12 months (HR, 4,5 (95% CI, 2,087-9,736), p=0,00018).","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136238527","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 determine additional factors and sex differences associated with the intermediate probability of heart failure (HF) with preserved ejection fraction (HFpEF) in asymptomatic patients working in the Arctic on a rotating basis. Material and methods . In the polar village of Yamburg (68° 21' 40 \"N), 99 men and 81 women with grade 1 and 2 hypertension (HTN) and normal blood pressure, comparable by age (p=0,450), length of service in the north (p=0,956), office systolic blood pressure (BP) (p=0,251), diastolic BP (p=0,579) were simultaneously examined. We performed echocardiography and assessed the risk of HFpEF by H2FPEF score (Heavy; Hypertensive; Atrial Fibrillation; Pulmonary Hypertension; Elder; Filling Pressure). A treadmill test, Baevsky index, 24-hour BP monitoring, and biochemical blood tests were performed. Results. Depending on H2FPEF score, participants were divided into groups: from 0 to 1 (group 1 — normal), from 2 to 5 (group 2 — intermediate probability of HFpEF). In men with intermediate probability of HFpEF, the Baevsky index (p=0,0048) and the incidence of resting body reserve dysaptation (p=0,0394) were higher, as well as a rapid BP increase during dosed exercise (p=0,0058) and a decrease in chronotropic reserve (p<0,0001) were noted. The presence of HTN in men increased the intermediate probability of HFpEF by 3,6 times, dyspnea at dosed exercise by 10 times, dysaptation to exercise by 5 times, the presence of left ventricular concentric remodeling by 8-10 times. In females with intermediate probability of HFpEF, dysaptation to exercise at rest (p=0,0120) and lower level of oxygen consumption during dosed exercise was more often determined (p=0,0485). The intermediate probability of HFpEF in women increased with autonomic nervous system dysfunction, an increase in the mean 24-hour systolic BP variability, the presence of dyspnea during dosed exercise (10 times), concentric left ventricular remodeling, and an increase in nonspecific inflammation markers (high-sensitivity C-reactive protein, IL-1β, IL-6).

To compare the incidence of leptin resistance (LR) in patients with acute and chronic coronary artery disease (CAD) and patients with acquired heart defects (AHD). Material and methods . The study included 234 patients: 114 patients with acute myocardial infarction (MI) and 120 patients with chronic CAD. The comparison group consisted of 48 patients with degenerative non-rheumatic AHD — aortic stenosis (AS). The control group consisted of 40 healthy volunteers. On the 1st day of hospitalization, the concentration of leptin and leptin receptor was measured, and the free leptin index (FLI) was assessed. LR was recorded at leptin &gt;6,45 ng/ ml and FLI &gt;25. Statistical data processing was carried out using the software package Statistica 10.0 and SPSS 17.0 for Windows. Results . Initially, LR in MI, chronic CAD and non-coronary disease was revealed in 64%, 56,2% and 25%, respectively. Significant differences in the incidence of LR were observed between patients with MI and chronic CAD relative to patients with AHD (p=0,02 and p=0,03, respectively), while no differences were found between patients with coronary pathology (p=0,82). Equation of patients for body mass index (BMI) did not affect the incidence of LR. High incidence of LR remained for patients with acute and chronic CAD, and amounted to 63% and 57,3%, respectively, while for patients with AS — 25%. Conclusion . Patients with acute and chronic CAD are characterized by a high LR incidence, in contrast to patients with AHD. The number of LR cases in patients with coronary pathology did not depend on BMI values, which indicates possible alternative leptin sources contributing the development of hyperleptinemia. In addition, studying the mechanisms underlying the leptin receptor decrease in CAD is necessary for adequate leptin effects and the prevention of LR.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136238714","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 prevalence of iron deficiency (ID) and anemia, as well as their impact on the clinical performance and quality of life in patients with acute decompensated heart failure (ADHF). Material and methods . The work was performed as part of cross-sectional multicenter screening study of ID in patients with heart failure (HF), managed by the Russian Society of Heart Failure. We examined 80 patients hospitalized in the cardiology department due to ADHF, who signed an informed consent. The diagnosis of ADHF was based on clinical signs of decompensated heart failure requiring intravenous therapy with diuretics, vasodilators, or inotropic agents. Results. The prevalence of ID was 80,0%, anemia — 35,0%, combination of anemia and ID — 31,2%. The mean age of patients with ID was 69,4±10,9 years. Patients with ID had higher HF class (40,6% vs 6,3% without ID, p<0,001), a higher incidence of hydrothorax (65,6% vs 31,3%, p=0,012), higher N-terminal pro-brain natriuretic peptide (5155,5 [3267,3;9786,3] pg/mL vs 2055,5 [708,8;2839,0] pg/mL, p<0,001), lower 6-minute walk test distance (155,9±84,0 m vs 239,6±82,7 m in patients without ID, p=0,01), lower quality of life according to the visual analogue scale (36,4±16,3 vs 46,3±20,7, p=0,036). ID was more often recorded in patients with frailty (95,7% vs 73,7% in patients without frailty, p=0,003), requiring a higher starting dose of intravenous diuretics (50,9±18,9 mg vs 38,6±12,3 mg without ID, p=0,021). Conclusion. In patients hospitalized due to ADHF, the prevalence of ID is 80,0%, anemia — 35,0%, combination of ID and anemia — 31,2%. Patients with ID have a higher N-terminal pro-brain natriuretic peptide level, more severe signs of decompensation, which requires higher starting dose of loop diuretics.

To evaluate the prognostic role of atrial fibrillation (AF) as a predictor of adverse events and outcomes in a cohort of patients with non-compaction cardiomyopathy (NCCM). Material and methods . We examined 216 patients with NCCM (140 men and 76 women, median age, 39 (30; 50) years). In addition to traditional clinical methods, all patients underwent late gadolinium-enhanced cardiac magnetic resonance imaging (MRI). The endpoints of the study included progression of NYHA class III heart failure (HF) with the need for hospitalization, ventricular tachyarrhythmias, and thromboembolic events (TEEs). Results. There were 54 out of 216 (23,6%) patients with AF, of which 18 had paroxysmal AF, 16 — persistent AF, and 20 — permanent AF. During the follow-up period (median follow-up, 36 (6; 72) months), 98 out of 216 (45,4%) patients with NCCM had adverse events and outcomes as follows: 16 (7,4%) had ventricular tachyarrhythmias, of which 12 (5,6%) — sudden cardiac death with successful resuscitation and implantation of an implantable cardioverter-defibrillator; 62 (28,7%) patients had NYHA III-IV class HF progression; 20 (9,3%) patients had TEEs. The rate of adverse cardiac events was significantly higher in patients with AF (74,1% vs 35,8%, χ 2 =23,93, p<0,001) compared with patients without AF, including the incidence of TEEs (20,4% vs 5,6%, χ 2 =10,58, p=0,002) and HF progression to class III (46,3% vs 22,8%, χ 2 =10,9, p=0,002). Multivariate analysis showed that the following most significant predictors of HF progression risk: left ventricular ejection fraction (LVEF) <50% according to cardiac MRI (hazard ratio (HR), 95,8; 95% confidence interval (CI), 10,2 -898,6; p=0,0001), presence of AF (HR, 8,2; 95% CI, 2,2-31,3; p=0,0022) and left atrial volume index (LAVI) >43 ml/m 2 (HR, 5,2; 95% CI, 2,1-12,8; p=0,0004); predictors of TEE risk were the presence of AF (HR, 6,5; 95% CI, 2,0-20,8; p=0,0020) and LAVI >43 ml/m 2 (HR, 6,0; 95% CI, 1,8-19,7; p=0,036). No association of AF with ventricular tachyarrhythmias was found in the study cohort of patients with NCCM. Predictors of ventricular tachyarrhythmias were LVEF <50% (HR, 4,5; 95% CI, 2,950,4; p=0,0241) and the presence of non-sustained ventricular tachycardia (HR, 3,5; 95% CI, 1,3-9,3 p=0,0139). Conclusion. The present study shows that, along with the traditional predictor of adverse events in patients with NCCM (LVEF <50%), the identified additional predictors (AF and LAVI >43 ml/m 2 ) can be used to identify patients at high risk of complicated NCCM for the timely prevention and treatment.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136238703","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 markers of serum apoptosis markers depending on the severity of coronary atherosclerosis, as well as to study their relationship with clinical and paraclinical characteristics of patients with coronary artery disease (CAD).Material and methods. The study included 176 people (105 men and 71 women), of which 150 were patients with an established diagnosis of CAD, 26 — healthy volunteers (control group). The patients were divided into the following groups: group 1 — with coronary atherosclerosis without stenosis (n=17); group 2 — with hemodynamically insignificant (stenosis <50%) coronary atherosclerosis (n=21); group 3 — with hemodynamically significant (stenosis >50%) coronary atherosclerosis (n=112). Group 4 was represented by healthy volunteers (n=26). Patients underwent coronary angiography using the SYNTAX score, echocardiography, extracranial artery duplex ultrasound. All subjects were studied for the serum level of apoptosis markers Bcl-2, Bax, Bcl-2/Bax, TRAIL and p53. Statistical processing was carried out using the Statistica 10.0 software. Differences were considered significant at p<0,05.Results. There was a very high correlation between the Bcl-2 (r=-0,84; p<0,001), Bax (r=0,83; p<0,001), Bcl-2/Bax (r=-0,86; p<0,001), p53 (r=0,80; p<0,001), TRAIL (r=-0,78; p<0,001) and the severity of coronary atherosclerosis. A correlation of varying strength and significance was revealed between the values of these apoptosis markers and a number of clinical and paraclinical characteristics of patients. In addition, there were significant differences (p<0,001) in Bcl-2, Bax, Bcl2/Bax, p53 and TRAIL between groups of patients with multifocal atherosclerosis, restenosis after previous revascularization and a history of myocardial infarction in comparison with patients without these signs.Conclusion. The correlations we have identified between laboratory signs of apoptosis and coronary lesions, clinical and paraclinical characteristics of patients, as well as the detected reliability of differences between groups with multifocal atherosclerosis, coronary artery restenosis and myocardial infarction in history, make it possible to consider these biomarkers as indicators of atherosclerosis severity.

At the same time, a single algorithm for phenotyping patients with HF has not been formulated yet. There is also no terminological unity in approaches. A review of 47 original articles published in the period from 2015 to 2022 in English on Elsevier, Pubmed, Web of Science databases with a following keywords \"HFpEF\", \"phenotype\", \"clusters\", \"phenotypic spectrum\", \"diastolic dysfunction\" makes it possible to identify several different approaches to phenotyping HFpEF, which are based on the etiology, pathophysiological mechanisms or clinical manifestations. Differences in the algorithms used for classification lead to the formation of groups of patients with different characteristics. Today it becomes obvious that in order to develop an optimal phenotyping approach and patient-oriented management of HFpEF, a combined analysis of a large number of anamnestic, clinical and paraclinical data is necessary.
