RESUMEN
AIM: To evaluate the impact of a decrease in glomerular filtration rate (GFR) on the prognosis of patients with chronic heart failure (CHF), to analyze real clinical practice regarding the frequency of prescribing pathogenetic therapy for CHF, achieving target dosages depending on the gradation of GFR in patients included in the CHF Register of the Tyumen region. MATERIALS AND METHODS: The analysis included medical data of 4077 patients (1662 men and 2415 women) with NYHA class I-IV CHF who underwent examination and treatment in medical organizations of the Tyumen region for the period from January 2020 to May 2023. Criteria for inclusion in the register: proven heart failure. Chronic kidney disease (CKD) was assessed by GFR calculated using the CKD-EPI formula (ml/min/1.73 m2). The primary end point was defined as death from all causes. RESULTS: GFR<60 ml/min/1.73 m2 was recorded in 34.6% of patients, more common in women (40.2 and 26.6%, respectively; p<0.001). When dividing patients into phenotypes according to LVEF, no statistically significant differences were found in the distribution of patients according to GFR. In patients with HFrEF and HFpEF GFR<45 ml/min/1.73 m2 was associated with an increased risk of meeting the endpoint. Analysis of prescribed pathogenetic therapy showed that in patients with HFrEF, the frequency of prescription of ACE inhibitors, â-blockers and MRA decreased (p=0.023, 006 and 0.01, respectively), and ARNI, on the contrary, increased with a decrease in GFR (p=0.026). In patients with HFpEF, a similar trend towards a decrease in the frequency of prescription of ACEIs and MCBs with a decrease in GFR (p<0.001) remained, but it was compensated by an inversely proportional increase in the frequency of prescription of ARBs (p<0.001). 100% of the target dosage is achieved in more than 90% of patients taking MRA across the entire LVEF range. While for â-blockers and ARNI/ACE/ARB the percentage of patients receiving the full therapeutic dosage of drugs is significantly lower. When analyzing target dosages of pathogenetic drugs, gradations of achieved doses were distributed evenly throughout the entire range of GFR. CONCLUSION: GFR<60 ml/min/1.73 m2 occurs in every 3 patients with CHF across the entire range of LVEF. A decrease in GFR worsens the prognosis of patients with both HFrEF and HFpEF, increasing in direct proportion with the severity of the stage of CKD. Inclusion of patients in the monitoring program within the framework of the CHF service allows the treatment to be significantly brought closer to optimal drug therapy, at the same time, certain efforts are required to overcome difficulties with titration to target dosages.

Aim To study the effectiveness of a treatment based on monitoring the soluble ST2 receptor (sST2) concentration in patients with chronic heart failure (CHF) with reduced left ventricular ejection fraction (LVEF) after acute decompensated heart failure (ADHF).Material and methods The study included 37 patients hospitalized for ADHF with LVEF ≤40% and sST2 concentration ≥37.8 ng/ml at the time of discharge from the hospital. Patients were randomized into two groups: a sST2 monitoring (sST2M) group (19 patients) and a standard therapy (ST) group (18 patients). The follow-up period was 12 months. At baseline, the groups practically did not differ by clinical, functional, laboratory, and instrumental characteristics. For the sST2M group, the goal was reducing the sST2 concentration by >30% of baseline or to <30 ng/ml.Results Therapy in both groups was comparable both in doses and in frequency of administration of basic drugs. However, the diuretic therapy was more frequently adjusted in the sST2M group (3.0 [1.0; 4.0] vs. 1.0 [0; 3.0] adjustments per patient, p = 0.047), which required more visits to the clinic (7.0 [6.0; 9.0] vs. 6.0 [6.0; 6.0] visits per patient, p=0.024). In the sST2M group at 6 months, the sST2 concentration was decreased by 43.3% (p=0.001), and 13 patients (72.2%) achieved the goal. In the ST group, the sST2 concentration was decreased by 38.5% (p=0.001), and 11 patients (68.8%) reached the target values. After 12 months, the downward trend continued in both groups. In both groups, the NT-proBNP concentration decreased: in the sST2M group by 27.7% (p=0.014), and in the ST group by 31.9% (p = 0.006). By the 12th month, the decrease remained only in the sST2M group. Only the sST2M group had an increase in LVEF (+28.5%, p=0.003), a decrease in left ventricular end-systolic volume (LVESV) (-12.0%, p=0.017), and a decrease in left atrial volume (-13.4%, p=0.045); at 12 months, LVEF remained increased (26%, p=0.006), and LA volume remained decreased (-14.3%, p=0.028). Quality of life and results of 6-minute walk test (6MWT) improved in both groups. For 6 months of treatment, the sST2M group had a significantly lower incidence of composite endpoints (CEP, cardiovascular death and decompensation/hospitalization due to HF), 26.3% (5 events) of the sST2M group compared to the ST group, 83.3% (15 events) (p=0.029), primarily due to a lower incidence of decompensated HF. For 12 months of follow-up, the incidence of CEP in the ST group was 122.2% (22 events), and 47.4% (9 events) in the sST2M group (p=0.035).Conclusions The tactics of sST2 monitoring used in the treatment of "high-risk" HFrEF patients (with high sST2 concentrations) is associated with increased LVEF, improved functional status of patients, a beneficial effect on LV remodeling, and decreased incidence of CEP.

AIM: To evaluate and compare the accuracy of volemic status determination by remote dielectric sensing with computed tomography (CT) in patients with acute decompensated heart failure. MATERIALS AND METHODS: In 28 patients volemic status was determined by ReDS (remote dielectric sensing), chest computed tomography (CCT), and chest X-ray twice during hospitalization (the day of admission and the day of discharge from the hospital). The ReDS measurements were then compared with CT data using software that allows the use of semi-automated tools to determine mean lung density (MLD). MLD results from Hounsfield Units [HU] were then converted to fluid levels (FU%), allowing them to be compared with ReDS values. In addition, to assess the effect of physical activity on the dynamics of pulmonary stasis there was performed 6-minute walk test (6MWT) followed by determination of volumic status by ReDS method. RESULTS: Correlation analysis revealed an average direct significant correlation (r=+0,5; p=0.001) between the CCT and ReDS data. Hypervolemia indexes according to the CCT revealed statistically significant decrease in the dynamics, which was also reflected in the ReDS index decrease. Lung fluid content according to ReDS averaged 38.2±4.6% on admission, and 34.5±3.9% on discharge (p=0.005). According to CT scan of the CCT, MLD at admission was 23.03±3.9%, at discharge 19.6±3.3% (p=0.003). The positive dynamics of the study methods was also reflected in the positive dynamics of NT-proBNP, which decreased by 46%. In the analysis of ReDS data before and after exercise, there was an increase in ReDS value after the performed 6MWT and it was 35.09±3.9% compared with the initial value of 34.5±3.9%. A strong direct significant correlation (r=+0.7; p=0.0001) was found between the ReDS before and after 6MWT at discharge.

AIM: To estimate the cost-effectiveness of dapagliflozin across the range of ejection fraction in patients with heart failure (HF) in Russian Federation. MATERIALS AND METHODS: Cost-effectiveness model was developed for estimate the use of dapagliflozin as part of standard therapy in patients with HF regardless of ejection fraction is unknown. The calculation of costs was carried out in a mathematical model adapted to the conditions of Russian healthcare system by using Russian costs inputs and patient population characteristics. RESULTS: In the model, dapagliflozin therapy yielded a mean of 0.209 additional life-years compared with standard of care in 10 years horizon. The incremental cost of 1 additional life-year was 665,715 RUB, which does not exceed the threshold of willingness to pay 2,235,202 RUB. CONCLUSION: Thus, the intensification of chronic HF therapy with dapagliflozin is cost effective. The use of dapagliflozin in a cohort of 1000 target patients over 10 years will avoid 146 hospitalizations and 39 emergency visits due to HF, as well as prevent 32 deaths from cardiovascular diseases.

AIM: To determine the effect of dapagliflozin therapy on myocardial remodeling and fibrosis according to magnetic resonance imaging (MRI) with contrast in patients with chronic heart failure (CHF) and atrial fibrillation (AF). MATERIALS AND METHODS: In the group of 22 patients with a combination of CHF and AF we analyzed the dynamics of remodeling parameters and assessed myocardial fibrosis during 6-month therapy with dapagliflozin according to cardiac MRI with contrast. RESULTS: After 6 months of dapagliflozin therapy there was a statistically significant increase in LVEF (27 [23-32]-32 [26.5-36.5] p-0.04) and a tendency to decrease volume and linear dimensions of LV, LP. There was no progression of myocardial fibrosis according to the results of cardiac MRI with contrast in patients with HFrFV and AF. CONCLUSIONS: Dapagliflozin therapy in patients with HFrEF and AF led to favorable myocardial remodeling changes.

The annual mortality of patients with clinically pronounced symptoms of chronic heart failure in the Russian Federation reaches 26-29%, i.e., from 880 to 986 thousand patients with heart failure die in the country in one year, which is comparable to the population of a large city. Providing care for patients with heart failure places a heavy burden on the country's health care system, making a significant contribution to mortality rates, hospitalization rates, including readmissions, which in turn requires considerable costs. The article presents an overview of registry studies that are devoted to assessing the effectiveness of diagnostics, the completeness of examinations, as well as the adequacy of ongoing drug treatment.

BACKGROUND: There is enough evidence of the negative impact of excess weight on the formation and progression of res piratory pathology. Given the continuing SARS-CoV-2 pandemic, it is relevant to determine the relationship between body mass index (BMI) and the clinical features of the novel coronavirus infection (NCI). AIM: To study the effect of BMI on the course of the acute SARS-COV-2 infection and the post-covid period. MATERIALS AND METHODS: AKTIV and AKTIV 2 are multicenter non-interventional real-world registers. The ÐÐТÐÐ registry (n=6396) includes non-overlapping outpatient and inpatient arms with 6 visits in each. The ÐÐТÐÐ 2 registry (n=2968) collected the data of hospitalized patients and included 3 visits. All subjects were divided into 3 groups: not overweight (n=2139), overweight (n=2931) and obese (n=2666). RESULTS: A higher BMI was significantly associated with a more severe course of the infection in the form of acute kidney injury (p=0.018), cytokine storm (p<0.001), serum C-reactive protein over 100 mg/l (p<0.001), and the need for targeted therapy (p<0.001) in the hospitalized patients. Obesity increased the odds of myocarditis by 1,84 times (95% confidence interval [CI]: 1,13-3,00) and the need for anticytokine therapy by 1,7 times (95% CI: 1,30-2,30).The patients with the 1st and 2nd degree obesity, undergoing the inpatient treatment, tended to have a higher probability of a mortality rate. While in case of morbid obesity patients this tendency is the most significant (odds ratio - 1,78; 95% CI: 1,13-2,70). At the same time, the patients whose chronical diseases first appeared after the convalescence period, and those who had certain complaints missing before SARS-CoV-2 infection, more often had BMI of more than 30 kg/m2 (p<0,001).Additionally, the odds of death increased by 2,23 times (95% CI: 1,05-4,72) within 3 months after recovery in obese people over the age of 60 yearsCONCLUSION. Overweight and/or obesity is a significant risk factor for severe course of the new coronavirus infection and the associated cardiovascular and kidney damage Overweight people and patients with the 1st and 2nd degree obesity tend to have a high risk of death of SARS-CoV-2 infection in both acute and post-covid periods. On top of that, in case of morbid obesity patients this tendency is statistically significant. Normalization of body weight is a strategic objective of modern medicine and can contribute to prevention of respiratory conditions, severe course and complications of the new coronavirus infection.

AIM: To evaluate the efficacy, safety and effect on the prognosis of cardiac contractility modulation (CCM) in patients with chronic heart failure (CHF) with reduced left ventricular ejection fraction and atrial fibrillation compared with the group of only optimal drug therapy (ODT) of the 12-month follow-up. MATERIALS AND METHODS: Patients (n=200) were sequentially included in two groups: group 1 patients with CHF who are on ODT in combination with implanted CCM devices (n=100), group 2 comparison patients with CHF who receive only ODT (n=100). Initially and after 12 months, 12-channel electrocardiography (ECG), transthoracic echocardiography, daily ECG-monitoring, determination of the level of NT-proBNP, a six-minute walk test and an assessment of the quality of life according to the Minnesota Questionnaire were performed. RESULTS: In the CCM therapy group, a significant clinical improvement was revealed, which was expressed in the form of a decrease in functional class CHF by NYHA (New York Heart Association), an increase in the distance of a six-minute walk test and an improvement in the quality of life according to Minnesota Questionnaire, as well as an improvement in left ventricle contractile function compared to the ODT group. The absence of a proarrhythmogenic effect of the CCM was shown. There was a significant decrease in the frequency of the readmission due to CHF and the probability of achieving the combined endpoint in the CCM therapy group compared with only ODT. CONCLUSION: The use of CCM in patients with CHF and atrial fibrillation is an effective and safe method of therapy that leads to the development of reverse remodeling of the myocardium, improves the clinical status of patients and reduces the frequency of readmission due to decompensation of CHF.

Obesity is an independent predictor of cardiovascular diseases (CVD), including heart failure (HF). Nevertheless, numerous studies have shown that patients with CVD who are overweight and slightly obese have a better short-term and moderate prognosis than thinner patients with CVD. This phenomenon has been called the obesity paradox. Understanding the obesity paradox is important in patients with HF, given the high prevalence of obesity in patients with HF. The article presents an overview of clinical studies devoted to the study of obesity as a risk factor for HF, the pathogenesis of HF in obesity, and highlights the issues of the obesity paradox and the treatment of obesity in this category of patients.

AIM: To study of the features of the clinical course and prognosis in patients with chronic heart failure with low ejection fraction (HFrEF) and atrial fibrillation (AF) depending on the width of the QRS complex. MATERIALS AND METHODS: We studied the case histories of 514 patients (aged 60.213.84 years, 78% men) with HFrEF, hospitalized at the Chazov National Medical Research Center of Cardiology (Moscow) for the period from Jan 1, 2017 to Dec 31, 2018. Patients were divided into 2 groups depending on the duration of the QRS complex. RESULTS: Clinical and statistical retrospective analysis of the medical histories of patients with HFrEF, depending on the QRS duration, showed the predominance of patients with a QRS complex size of less than 130 ms (60.7%). In HFrEF, the expansion of the QRS complex is accompanied by an increase in the rate of readmission in patients with sinus rhythm (p=0.004). In patients with AF, the rehospitalization rate is significantly higher than in sinus rhythm and does not depend on the QRS duration (p=0.001). The incidence of unfavorable outcomes increases in connection with the addition of AF, which is most likely a more significant risk factor than QRS width. CONCLUSION: These results highlight that patients with AF and a narrow QRS complex have the same poor prognosis as those with a wide QRS complex and require the close attention of cardiologists.

AIM: To study the efficacy and safety of exogenous phosphocreatine (EF) in patients with chronic heart failure (CHF). MATERIALS AND METHODS: The all-Russian prospective observational study BYHEART included 842 patients who were treated with EF. Before and after the course of EF therapy, the following studies were conducted: a questionnaire on the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and a clinical condition assessment scale (SHOCK), transthoracic echocardiography with an assessment of the left ventricular ejection fraction, a 6-minute walk test, determination of the level of pro-natriuretic N-terminal peptide (NT-proBNP), glomerular filtration rate. All patients before the course of EF received long-term optimal drug therapy of CHF. RESULTS: Statistical analysis was carried out in the general group of patients (n=842), as well as in groups of patients A (n=418, the course of treatment of EF is less than 20 g /course) and group B (n=424, the course of treatment of EF is greater than or equal to 20 g/course). The results obtained demonstrate a positive effect of the use of the course of therapy of EF in patients with CHF on the quality of life (QOL), reverse left ventricular remodeling, functional class of CHF, as well as the concentration of NT-pro-BNP, especially in the group of patients who received more than 20 grams of the medication. CONCLUSION: The use of EF is a promising pharmacological method of treatment in addition to optimal drug therapy in patients with CHF.

The current worldwide prevalence of heart failure is growing, while its combination with cardiovascular and other conditions determines a poor prognosis in these patients. Furthermore, acute decompensated heart failure is associated with a low survival rate mostly caused by target organ damage. The effects of early administration of SGLT2 inhibitors on renal function in patients with acute decompensated heart failure are being studied to determine the possibility of improving response to treatment, as well as partial or complete recovery of renal function. The goal of the review was to synthesize currently available evidence for the use of SGLT2 inhibitors in patients with acute decompensated heart failure. A systematic search for studies published from 2018 to 2021 and their analysis was carried out in the following databases: Web of Science, Scopus, PubMed/MEDLINE.

This paper summarizes the data from updated international protocols and guidelines for diagnosis of transthyretin amyloid cardiomyopathy (ATTR-CM). The invasive and non-invasive diagnosis techniques and their combinations are briefly reviewed; the evidentiary foundations for each diagnostic option and tool are analyzed. The paper describes a customized algorithm for sequential diagnosis and differential diagnosis of patients with suspected ATTR-CM with allowance for the combination of clinical signs and diagnostic findings. Along with the awareness of primary care providers about the red flags of the disease and visualization criteria, as well as providing information to the patients about the possibility of performing therapy of ATTR amyloidosis and the risks of delayed diagnosis, the proposed algorithm enables timely patient routing and prescribing specific treatment.

AIM: Study the impact of various combinations of comorbid original diseases in patients infected with COVID-19 later on the disease progression and outcomes of the new coronavirus infection. MATERIALS AND METHODS: The ACTIV registry was created on the Eurasian Association of Therapists initiative. 5,808 patients have been included in the registry: men and women with COVID-19 treated at hospital or at home. CLINICALTRIALS: gov ID NCT04492384. RESULTS: Most patients with COVID-19 have original comorbid diseases (oCDs). Polymorbidity assessed by way of simple counting of oCDs is an independent factor in negative outcomes of COVID-19. Search for most frequent combinations of 2, 3 and 4 oCDs has revealed absolute domination of cardiovascular diseases (all possible variants). The most unfavorable combination of 2 oCDs includes atrial hypertension (AH) and chronic heart failure (CHF). The most unfavorable combination of 3 oCDs includes AH, coronary heart disease (CHD) and CHF; the worst combination of 4 oCDs includes AH, CHD, CHF and diabetes mellitus. Such combinations increased the risk of lethal outcomes 3.963, 4.082 and 4.215 times respectively. CONCLUSION: Polymorbidity determined by way of simple counting of diseases may be estimated as a factor in the lethal outcome risk in the acute phase of COVID-19 in real practice. Most frequent combinations of 2, 3 and 4 diseases in patients with COVID-19 primarily include cardiovascular diseases (AH, CHD and CHF), diabetes mellitus and obesity. Combinations of such diseases increase the COVID-19 lethal outcome risk.

Aim To study the effect of regular drug therapy for cardiovascular and other diseases preceding the COVID-19 infection on severity and outcome of COVID-19 based on data of the ACTIVE (Analysis of dynamics of Comorbidities in paTIents who surVived SARS-CoV-2 infEction) registry.Material and methods The ACTIVE registry was created at the initiative of the Eurasian Association of Therapists. The registry includes 5 808 male and female patients diagnosed with COVID-19 treated in a hospital or at home with a due protection of patients' privacy (data of nasal and throat smears; antibody titer; typical CT imaging features). The register territory included 7 countries: the Russian Federation, the Republic of Armenia, the Republic of Belarus, the Republic of Kazakhstan, the Kyrgyz Republic, the Republic of Moldova, and the Republic of Uzbekistan. The registry design: a closed, multicenter registry with two nonoverlapping arms (outpatient arm and in-patient arm). The registry scheduled 6 visits, 3 in-person visits during the acute period and 3 virtual visits (telephone calls) at 3, 6, and 12 mos. Patient enrollment started on June 29, 2020 and was completed on October 29, 2020. The registry completion is scheduled for October 29, 2022. The registry ID: ClinicalTrials.gov: NCT04492384. In this fragment of the study of registry data, the work group analyzed the effect of therapy for comorbidities at baseline on severity and outcomes of the novel coronavirus infection. The study population included only the patients who took their medicines on a regular basis while the comparison population consisted of noncompliant patients (irregular drug intake or not taking drugs at all despite indications for the treatment).Results The analysis of the ACTIVE registry database included 5808 patients. The vast majority of patients with COVID-19 had comorbidities with prevalence of cardiovascular diseases. Medicines used for the treatment of COVID-19 comorbidities influenced the course of the infectious disease in different ways. A lower risk of fatal outcome was associated with the statin treatment in patients with ischemic heart disease (IHD); with angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor antagonists and with beta-blockers in patients with IHD, arterial hypertension, chronic heart failure (CHF), and atrial fibrillation; with oral anticoagulants (OAC), primarily direct OAC, clopidogrel/prasugrel/ticagrelor in patients with IHD; with oral antihyperglycemic therapy in patients with type 2 diabetes mellitus (DM); and with long-acting insulins in patients with type 1 DM. A higher risk of fatal outcome was associated with the spironolactone treatment in patients with CHF and with inhaled corticosteroids (iCS) in patients with chronic obstructive pulmonary disease (COPD).Conclusion In the epoch of COVID-19 pandemic, a lower risk of severe course of the coronavirus infection was observed for patients with chronic noninfectious comorbidities highly compliant with the base treatment of the comorbidity.

Aim To evaluate the prognostic significance of the left ventricular global function index (LV GFI) in patients with acute coronary syndrome (ACS) using echocardiography (EchoCG).Material and methods The LV GFI is an index that integrates LV cavity volumes, stroke volume, and myocardial volume. This study included 2169 patients with ACS (1340 (61.8%) men) aged 64.1±12.6 years from two observational multicenter studies, ORACLE I and ORACLE II. 1800 (83â%) cases were associated with increased concentrations of myocardial injury markers, including 826 (38.1â%) cases of ST segment elevation myocardial infarction (MI). The observation was started on the 10th day of clinical condition stabilization and lasted for one year. EchoCG was performed with evaluation of LV GFI, which was calculated as a ratio of LV stroke volume to LV global volume. The LV global volume was calculated as a sum of mean LV cavity volume (LV end-diastolic volume + LV end-systolic volumeâ/â2) and LV myocardial volume.Results The main outcome of the study was all-cause death (n=193); recurrent coronary complications (n=253) were analyzed separately. The only EchoCG parameter indicating an adverse outcome during the one-year follow-up was a LV GFI decrease to below 22.6â% with a sensitivity of 72â% and a specificity of 60% (area under the curve, AUC=0.63). A LV GFI <22.6â% was an independent predictor of all-cause death (p=0.019) along with age (p=0.0001), history of MI (p=0.034), and presence of heart failure (HF) (p=0.044), diabetes mellitus (p=0.012), and peripheral atherosclerosis (p=0.001). The LV GFI <22.6â%, (p=0.044), heart rate upon discharge from the hospital (p=0.050), history of MI (p=0.006), presence of HF (p=0.014), and peripheral atherosclerosis (p=0.001) were also independent predictors for recurrent coronary complications. Decreased LV GFI was associated with the risk of fatal outcomes independent of the LV ejection fraction at baseline.Conclusion In patients with ACS, the left ventricular global function index is an independent predictor for all-cause death and recurrent coronary complications and may be used for risk stratification.
