In September 2021, an online meeting of the Council of Experts was held. The proposed focus of discussion was publishing the results of an international prospective, randomized, double-blind, placebo-controlled study VICTORIA. The objective of the VICTORIA study was evaluation of the efficacy and safety of supplementing a standard therapy with vericiguat at a target dose of 10 mg twice a day as compared to placebo for prevention of cardiovascular death and hospitalization for heart failure (HF) in patients with clinical manifestations of chronic HF and left ventricular ejection fraction

This Expert Council focuses on the meta-analysis of studies on the risk of atrial fibrillation (AF) in patients taking omega-3 polyunsaturated fatty acids (PUFA) and of data on the omega-3 PUFA treatment in patients with cardiovascular and kidney diseases.The major statements of the Expert Council: the meta-analysis of AF risk in patients taking omega-3 PUFA showed an increased risk of this arrhythmia. However, it should be taken into account that the risk of complications was low, and there was no significant increase in the risk of AF when omega-3 PUFA was used at a dose of ≤1 g and a standard dose of the only omega-3 PUFA drug registered in the Russian Federation, considering all AF episodes in the ASCEND study.At the present time, according to Russian and international clinical guidelines, the use of omega-3 PUFA can be considered in the following cases: • for patients with chronic heart failure (CHF) with reduced left ventricular ejection fraction as a supplement to the basic therapy (2B class of recommendations according to the 2020 Russian Society of Cardiology guidelines (RSC) and the 2022 AHA / ACC / HFSA guidelines); • for patients with hypertriglyceridemia (>1.5 mmol/l) as a part of combination therapy (IIb class of recommendations and B level of evidence according to the 2021 European guidelines on cardiovascular disease prevention, etc.); • for adult patients with stage 3-4 chronic kidney disease (CKD), long-chain omega-3 PUFA 2 g/day is recommended for reducing the level of triglycerides (2C class of recommendations). Data on the use of omega-3 PUFA for other indications are heterogenous, which can be partially explained by using different form and doses of the drugs.

Aim. To assess the tolerability of vaccination with the first component of Gam-COVID-Vac (Sputnik V), the frequency and nature of adverse events following immunization (AEFI) depending on gender, age, obesity, and chronic diseases.Material and Methods. The study included male and female patients who received the first component of the Gam-COVIDVac vaccine at MSU Medical Center. Subsequently, after 14 days, a remote survey of respondents was conducted to collect the data regarding the development of adverse events requiring the use of drug treatment or medical care.Results. The study included 732 participants. Two-thirds of the respondents (65.8%) reported the development of AEFI: pain at the injection site (46.9%), fever (25.5%), muscle pain (29.9%), and headache (27%). At the same time, women noted the occurrence of AEFI more often than men (72.4% vs 57.5%, p < 0.05), and AEFI duration was also longer. Patients over 60 years of age reported less fever than patients under 40 years of age (21.0% vs 31.1%; p < 0.031). Young age and female gender were independent predictors of AEFI after vaccination with the first component of the Sputnik V vaccine. Obesity and a history of reported chronic non-infectious diseases did not correlate with the occurrence of AEFI.Conclusion. Adverse events after the administration of the first component of Gam-COVID-Vac (Sputnik V) were of short duration and were easily tolerated by both young and old patients.

Aim To evaluate clinical efficacy of the proactive anti-inflammatory therapy in patients hospitalized for COVID-19 with pneumonia and a risk of “cytokine storm”.Material and methods The COLORIT study was a comparative study with randomization into 4 groups: colchicine (n=21) 1 mg for the first 3 days followed by 0.5 mg/day through day 12 or discharge from the hospital; secukinumab 300 mg/day, s.c., as a single dose (n=20); ruxolitinib 5 mg, twice a day (n=10); and a control group with no anti-inflammatory therapy (n=22). The effect was evaluated after 12±2 days of inpatient treatment or upon discharge, what comes first. For ethical reasons, completely randomized recruitment to the control group was not possible. Thus, for data analysis, 17 patients who did not receive any anti-inflammatory therapy for various reasons not related with inclusion into the study were added to the control group of 5 randomized patients. Inclusion criteria: presence of coronavirus pneumonia (positive PCR test for SARS-CoV-2 RNA or specific clinical presentation of pneumonia; IDC-10 codes U07.1 and U07.2); C-reactive protein (CRP) concentration >60 mg/l or its threefold increase from baseline; at least 2 of 4 symptoms (fever >37.5 °C, persistent cough, shortness of breath with inspiratory rate >20 per min or blood saturation with oxygen th–9th day of disease. The study primary endpoint was changes in COVID Clinical Condition Scale (CCS-COVID) score. The secondary endpoints were the dynamics of CRP and changes in the area of lung lesion according to data of computed tomography (CT) of the lungs from the date of randomization to 12±2 days.Results All three drugs significantly reduced inflammation, improved the clinical course of the disease, and decreased the disease severity as evaluated by the CCS score: in the ruxolitinib group, by 5.5 (p=0.004); in the secukinumab group, by 4 (p=0.096); in the colchicine group, by 4 (p=0.017), and in the control group, by 2 (р=0.329). In all three groups, the CCS-COVID score was 2–3 by the end of observation period, which corresponded to a mild process, while in the control group, the score was 7 (р=0.005). Time-related changes in CRP were significant in all three anti-inflammatory treatment groups with no statistical difference between the groups. By the end of the study, changes in CT of the lungs were nonsignificant.Conclusion In severe СOVID-19 with a risk of “cytokine storm”, the proactive therapy with ruxolitinib, colchicine, and secukinumab significantly reduces the inflammation severity, prevents the disease progression, and results in clinical improvement.

Heart failure with reduced left ventricular ejection fraction (LV EF) (HFrEF) is a significant issue of health care due to increasing indexes of morbidity and mortality. The emergence of a number of drugs and implantable devices for the treatment of HFrEF has allowed improvement of patients’ well-being and prognosis. However, high mortality and recurrent decompensated heart failure remain a substantial issue and stimulate the search for new methods of CHF treatment. Cardiac contractility modulation (CCM) is a method of managing patients with HFrEF. Available data from randomized clinical trials (RCT) indicate the efficacy of CCM in improvement of patients’ well-being and quality of life. The question remains open: what effect does CCM have on LV reverse remodeling? Experimental data and results of observational studies suggest a possibility of reverse remodeling by CCM; however, this has not been confirmed in RCT. Also, it remains unclear how CCM influences the frequency of hospitalizations for decompensated heart failure and the death rate of patients with HFrEF. Results of both RCTs and observational studies have shown a moderate improvement of quality of life associated with CCM. Furthermore, RCTs have not found any increase in LV EF due to the therapy, nor has a meta-analysis of RCTs revealed any improvement of the prognosis associated with CCM. Further RCTs are needed to evaluate the effect of CCM on reverse remodeling, survival rate, and to determine the place of CCM in the treatment of patients with CHF.

Aim To evaluate the prevalence of iron deficiency (ID) in Russian patients with heart failure (HF).Material and methods Iron metabolism variables were studied in 498 (198 women, 300 men) patients with HF. Data were evaluated at admission for HF (97 %) or during an outpatient visit (3 %). ID was determined according to the European Society of Cardiology Guidelines.Results 83.1 % of patients had ID; only 43.5 % of patients with ID had anemia. Patients with ID were older: 70.0 [63.0;79.0] vs. 66.0 years [57.0;75.2] (p=0.009). The number of patients with ID increased in parallel with the increase in HF functional class (FC). Among patients with ID, fewer people were past or current alcohol users (p=0.002), and a greater number of patients had atrial fibrillation (60.1 vs. 45.2 %, p=0.016). A multiple logistic regression showed that more severe HF (HF FC) was associated with a higher incidence of ID detection, whereas past alcohol use was associated with less pronounced ID. An increase in N-terminal pro-brain natriuretic peptide (NT-proBNP) by 100 pg/ml was associated with an increased likelihood of ID (odds ratio, 1.006, 95 % confidence interval: 1.002–1.011, p=0.0152).Conclusion The incidence rate of HF patients is high in the Russian Federation (83.1 %). Only 43.5 % of these patients had anemia. The prevalence of ID in the study population increased with increases in HF FC and NT-proBNP.

Aim Dilated cardiomyopathy (DCMP) is a major cause for severe heart failure. Development of a combination (drug and surgery) treatment of this disease is relevant. This prospective observational study was aimed at evaluating short- and long-term results of extracardiac mesh implantation in DCMP patients with heart failure resistant to the optimum drug therapy.Material and methods The extracardiac mesh ACOR-1 was implanted in 15 patients with DCMP. All meshes were produced individually for each patient and made of Gelweave (great Britain) vascular graft strips. The mesh size corresponded to the heart diastolic size, which was measured after achieving a maximum possible clinical improvement for the patient. Long-term results were followed for up to 4 years. Mean age of patients was 43.1±10.8 years (from 28 to 62 years). One patient was followed up for 18 years. Data of that patient were presented as a clinical case report.Results From October, 2003 through October, 2007, 15 DCMP patients received mesh implants. Cases of in-hospital death were absent. In 3 mos. after the surgery, left ventricular volumes decreased (end-diastolic volume decreased from 251.7±80.7 to 229.0±61.3 ml; end-systolic volume decreased from 182.3±73.6 to 167.7±46.2 ml), and the left ventricular pump function improved (ejection fraction increased from 25.2±6.0 to 27.1±5.1 %; cardiac index increased from 2.0±0.5 to 2.4±0.7 ml /min /m2). The functional state of patients improved by one NYHA class, from 3.7±0.3 to 2.8±0.6. In some cases, the left ventricular size and the systolic function completely normalized. There were no episodes of circulatory decompensation in the long term after surgery. Actuarial survival for the observation period was 100%.Conclusion Implantation of extracardiac mesh prevented progression of heart dilatation and, in combination with drug therapy, it may represent an effective method for treatment of DCMP.

Major principles for treatment of chronic heart failure with reduced left ventricular ejection fraction Aim To compare the net effect of simultaneous treatment with ARNI and SGLT2 inhibitors with the triple neurohormonal blockade in stable or decompensated patients with CHF based on Russian data.Material and methods We analyzed the risk of death per 100 patient-years in patients with HFrEF. Stable patients were followed up at the A.L. Myasnikov Institute of Cardiology (presently, A.L. Myasnikov Research Institute of Clinical Cardiology of the National Medical Research Center of Cardiology) from 2006 through 2007; data from the EPOCH-Decompensation-CHF study were used for decompensated patients (12.2 % and 36.8 %, respectively).Results When patients with stable HFrEF were successively switched from renin-angiotensin-aldosterone system (RAAS) inhibitors to ARNI (–16 %) and subsequently supplemented with SGLT2 (–13 %) the risk of death per 100 patient-years decreased from 12.2 % to 8.9 % (total risk decreased by 27 %; to save one patient the ARNI+ SGLT2 combination has to be prescribed to 30 patients). The estimated risk of death upon discharge from the hospital for the patients with decompensated CHF switched from RAAS inhibitors to ARNI (–16 %) and subsequently supplemented with SGLT2 (–13 %) was 26.9 deaths per 100 patient-years, whereas the number of patients to be treated for saving one life was only 10. Based on available data that demonstrate a greater effect of ARNI+ SGLT2 in patients immediately after CHF aggravation, the risk of death was recalculated. According to this analysis, the death rate per 1000 patient-years decreased from 36.8 to 19.9 % (relative risk decrease, 46 %), and to save one life only 6 patients had to be treated after they have achieved compensation of HFrEF.Conclusions This analysis shows the importance of early initiation of the ARNI+ SGLT2 therapy in patients with both decompensated and with stable HFrEF.

Aim To study the etiology and the dynamics of prevalence and mortality of CHF; to evaluate the treatment coverage of such patients in a representative sample of the European part of the Russian Federation for a 20-year period. Material and methods A representative sample of the European part of the Russian Federation followed up for 2002 through 2017 (n=19 276); a representative sample of the population of the Nizhny Novgorod region examined in 1998 (n=1922).Results During the observation period since 2002, the incidence of major CHF symptoms (tachycardia, edema, shortness of breath, weakness) tended to decrease while the prevalence of cardiovascular diseases has statistically significantly increased. During the period from 1998 through 2017, the prevalence of I-IV functional class (FC) CHF increased from 6.1 % to 8.2 % whereas III-IV FC CHF increased from 1.8 % to 3.1 %. The main causes for the development of CHF remained arterial hypertension and ischemic heart disease; the role of myocardial infarction and diabetes mellitus as causes for CHF was noted. For the analyzed period, the number of treatment components and the coverage of basic therapy for patients with CHF increased, which probably accounts for a slower increase in the disease prevalence by 2007–2017. The prognosis of patients was unfavorable: in I-II FC CHF, the median survival was 8.4 (95 % CI: 7.8–9.1) years and in III-IV FC CHF, the median survival was 3.8 (95 % CI: 3.4–4.2) years.

In recent years there has been significant interest in treating iron deficiency (ID) in patients with heart failure (HF) due to its high prevalence and detrimental effects in this population. As stated in the 2020 Russain HF guidelines, Intravenous ferric carboxymaltose remains the only proven therapy for ID.This document was prompted by the results from the recent AFFIRM-AHF trial which demonstrates that treatment of ID after acute HF decompensation reduces the risk of future decompensations. Experts have concluded that in HF patients with acute decompensation, a left ventricular ejection fraction of < 50% and ID, Intravenous ferric carboxymaltose reduces future HF hospitalisations. Patients with stable HF may also benefit from treatment of ID to improve quality of life and alleviate symptoms. It is, therefore, reasonable to screen for and treat ID in patients with HF.

The article attempts to analyze the change in philosophy in approaches to the treatment of COVID-19 that have occurred in recent months, based on published research and their own experience in the treatment of a new coronavirus infection at the medical research and education center of Moscow state University. Emphasis is placed on the rationale for the phased use of different types of therapy. The reasons for using spironolactone in patients with COVID-19 as a drug for etiotropic and pathogenetic therapy are discussed in detail. The authors conclude that the use of antiviral drugs in combination with drugs that prevent the entry of the SARS-CoV-2 virus into cells from the first days of the disease should be supplemented with pre-emptive anti-inflammatory therapy that interrupts the progression of the disease. The parallel use of anticoagulants that reduce the risk of thrombotic and thromboembolic complications.

Actuality One of the most widely discussed treatments for patients with COVID-19, especially at the beginning of the epidemy, was the use of the antimalarial drug hydroxychloroquine (HCQ). The first small non-randomized trials showed the ability of HCQ and its combination with azithromycin to accelerate the elimination of the virus and ease the acute phase of the disease. Later, large, randomized trials did not confirm it (RECOVERY, SOLIDARITY). This study is a case-control study in which we compared patients who received and did not receive HCQ.Material and Methods 103 patients (25 in the HCQ treatment group and 78 in the control group) with confirmed COVID-19 (SARS-CoV-2 virus RNA was detected in 26 of 73 in the control group (35.6%) and in 10 of 25 (40%) in the HCQ group) and in the rest - a typical picture of viral pneumonia on multislice computed tomography [MSCT]) were included in the analysis. The severity of lung damage was limited to stages I-II, the CRP level should not exceed 60 mg/dL, and oxygen saturation in the air within 92-98%. We planned to analysis the duration of treatment of patients in the hospital, the days until the normalization of body temperature, the number of points according to the original SHOCS-COVID integral scale, and changes in its components (C-reactive protein (CRP), D-dimer, and the percentage of lung damage according to MSCT).Results Analysis for the whole group revealed a statistically significant increase in the time to normalization of body temperature from 4 to 7 days (by 3 days, pConclusion We have not identified any positive properties of HCQ and its ability to influence the severity of COVID-19. This antimalarial agent slows down the normalization of the body's inflammatory response and lengthens the time spent in the hospital. HCQ should not be used in the treatment of COVID-19.

ActualityThe course of the novel coronavirus disease (COVID-19) is unpredictable. It manifests in some cases as increasing inflammation to even the onset of a cytokine storm and irreversible progression of acute respiratory syndrome, which is associated with the risk of death in patients. Thus, proactive anti-inflammatory therapy remains an open serious question in patients with COVID-19 and pneumonia, who still have signs of inflammation on days 7–9 of the disease: elevated C-reactive protein (CRP)>60 mg/dL and at least two of the four clinical signs: fever >37.5°C; persistent cough; dyspnea (RR >20 brpm) and/or reduced oxygen blood saturation ObjectiveCompare efficacy and safety of colchicine compared to the management of patients with COVID-19 without specific anti-inflammatory therapy.Material and MethodsInitially, 20 people were expected to be randomized in the control group. However, enrollment to the control group was discontinued subsequently after the inclusion of 5 patients due to the risk of severe deterioration in the absence of anti-inflammatory treatment. Therefore, 17 patients, who had not received anti-inflammatory therapy when treated in the MSU Medical Research and Educational Center before the study, were also included in the control group. The effects were assessed on day 12 after the inclusion or at discharge if it occurred earlier than on day 12. The primary endpoint was the changes in the SHOCS-COVID score, which includes the assessment of the patient’s clinical condition, CT score of the lung tissue damage, the severity of systemic inflammation (CRP changes), and the risk of thrombotic complications (D-dimer) [1].ResultsThe median SHOCS score decreased from 8 to 2 (p = 0.017), i.e., from moderate to mild degree, in the colchicine group. The change in the SHOCS-COVID score was minimal and statistically insignificant in the control group. In patients with COVID-19 treated with colchicine, the CRP levels decreased rapidly and normalized (from 99.4 to 4.2 mg/dL, pConclusionsColchicine 1 mg for 1-3 days followed by 0.5 mg/day for 14 days is effective as a proactive anti-inflammatory therapy in hospitalized patients with COVID-19 and viral pneumonia. The management of such patients without proactive anti-inflammatory therapy is likely to be unreasonable and may worsen the course of COVID-19. However, the findings should be treated with caution, given the small size of the trial.

Diagnosis of heart failure with preserved ejection fraction (HFpEF) is associated with certain difficulties since many patients with HFpEF have a slight left ventricular diastolic dysfunction and normal filling pressure at rest. Diagnosis of HFpEF is improved by using diastolic transthoracic stress-echocardiography with dosed exercise (or diastolic stress test), which allows detection of increased filling pressure during the exercise. The present expert consensus explains the requirement for using the diastolic stress test in diagnosing HFpEF from clinical and pathophysiological standpoints; defines indications for the test with a description of its methodological aspects; and addresses issues of using the test in special patient groups.

Aim Patients with heart failure with reduced left ventricular (LV) ejection fraction (HFrEF) who have had acute myocardial infarction have an unfavorable prognosis, largely due to ventricular arrhythmias (VA) and risk of sudden cardiac death (SCD). The optimal treatment (triple neurohormonal blockade plus implantable cardioverter defibrillator and cardiac resynchronization therapy) reduced the risk of SCD primarily due to reverse cardiac remodeling, but has not solved this problem completely. Efficacy of purified ω-3 polyunsaturated fatty acid esters (PUFA) in low doses (1 g/day) in reducing VA and risk of SCD in HFrEF patients was demonstrated in two large randomized clinical trials. The PUFA effects was suggested to be related also with increased heart rhythm variability (HRV) and chronotropic action, which might depend on the drug dose. The present open, prospective, randomized, comparative study in parallel groups evaluated the effect of Omacor in different doses on noninvasive markers of SCD risk in patients with ischemic HFrEF receiving the optimal drug therapy.Methods Patients (n=40) were randomized at a 1:1:2 ratio to the control group (n=10), the Omacor 1 g/day treatment group (n=10), and the Omacor 2 g/day treatment group (n=20) and were followed up for 12 months. Clinical evaluation included changes in the CHF functional class (FC) and Clinical Condition Scale (CCS) score; concentration of N-terminal pro-hormone brain natriuretic peptide (NT-proBNP); and peak oxygen consumption during exercise (peak VO2). The LV function was evaluated by LVEF. Holter ECG monitoring was used for evaluation of HRV (SDNN), average 24-h heart rate (HR), number of ventricular extrasystoles (VE) per hour and severity of VA, and presence of paired VE and VT runs.Results Improvement of CHF FC became significant only with the high-dose Omacor treatment (2 g/day). The CCS score showed a tendency towards decrease also with a lower dose (1 g/day) whereas the level of NT-proBNP significantly decreased with both Omacor doses. The increase in LV EF was significant only with the use of Omacor 2 g/day (+3 %, р=0.002). A negative chronotropic effect of ω-3 PUFA was observed. Average 24-h HR decreased by 8 bpm (р=0.05) and 11 bpm (рConclusion Since HR, HRV, and VA are closely interrelated, the effect of ω-3 PUFA specifically on these noninvasive markers apparently determines its ability to decrease the risk of SCD in patients with ischemic HFrEF. The antiarrhythmic effect of Omacor was greater with higher doses of this drug.

The article focuses on effective treatment of the novel coronavirus infection (COVID-19) at early stages and substantiates the requirement for antiviral therapy and for decreasing the viral load to prevent the infection progression. The absence of a specific antiviral therapy for the SARS-CoV-2 virus is stated. The authors analyzed results of early randomized studies using lopinavir/ritonavir, remdesivir, and favipiravir in COVID-19 and their potential for the treatment of novel coronavirus infection. Among the drugs blocking the virus entry into cells, the greatest attention was paid to the antimalaria drugs, chloroquine and hydroxychloroquine. The article addresses in detail ineffectiveness and potential danger of hydroxychloroquine, which demonstrated neither a decrease in the time of clinical recovery nor any improvement of prognosis for patients with COVID-19. The major objective was substantiating a possible use of bromhexine, a mucolytic and anticough drug, which can inhibit transmembrane serin protease 2 required for entry of the SARS-CoV-2 virus into cells. Spironolactone may have a similar feature. Due to its antiandrogenic effects, spironolactone can inhibit X-chromosome-related synthesis of ACE-2 receptors and activation of transmembrane serin protease 2. In addition to slowing the virus entry into cells, spironolactone decreases severity of fibrosis in different organs, including the lungs. The major part of the article addresses clinical examples of managing patients with COVID-19 at the University Clinic of the Medical Research and Educational Centre of the M. V. Lomonosov Moscow State University, including successful treatment with schemes containing bromhexine and spironolactone. In conclusion, the authors described the design of a randomized, prospective BISCUIT study performed at the University Clinic of the M. V. Lomonosov Moscow State University with an objective of evaluating the efficacy of this scheme.

Chronic heart failure (CHF) and type 2 diabetes mellitus (DM2) and very common comorbidities with bidirectional, mutually aggravating courses. DM2 is known as an independent risk factor of cardiovascular complications whereas a higher CHF functional class is associated with increased risk of DM2. At present time, hypoglycemic drugs of the gliflozin class and the angiotensin receptor-neprilysin inhibitor (ARNI) are widely discussed in connection with their use in the treatment of patients with CHF and DM. The PARADIGM-HF study investigated effects of long-term treatment of CHF with reduced ejection fraction with presently the only representative of the ARNI class, a single supramolecular complex of valsartan-sacubitril. This medicine has already exceled enalapril at the effect not only on the incidence of nonfatal and fatal cardiovascular events but also on general mortality. Mean age of patients included into that study was 63.8±11.5 years; 21 % of them were females. In real-life clinical practice, physicians more frequently see older patients, and most of them are females, particularly with DM2. On the other hand, sodium-glucose cotransporter-2 inhibitors, including empagliflozin, significantly decreased the death rate and the frequency of CHF exacerbations in patients with DM2 and concomitant cardiovascular diseases, including CHF. This article describes a clinical case of initiating the valsartan-sacubitril treatment in combination with empagliflozin in an elderly female patient with congestive CHF with intermediate ejection fraction (EF) and comorbidities, including a history of myocardial infarction and DM2. Of interest is the rapid positive dynamics of clinical, laboratory (NT-proBNP) and instrumental (echocardiography) markers of CHF. At 3 months, the EF “recovered” from intermediate to preserved during the use of a comprehensive cardio-reno-metabolic approach. Both cardiologists and endocrinologists should definitely consider this approach in managing such patients since current cardiological drugs have additional pleiotropic metabolic effects whereas hypoglycemic drugs, in their turn, influence the cardiological prognosis.

Aim To study tactics of outpatient physicians in choosing the treatment when the previous double antihypertensive therapy (AHT) fails and to analyze the effectivity of an amlodipine/indapamide/perindopril arginine triple combination (TC).Material and methods The program included 1252 patients with arterial hypertension (AH); the TC group consisted of 992 (79.23 %) patients (38.3 % males; age, 61.6 [55.0; 67.9]); the control group included 260 (20.77 %) patients (37.7 % males; age, 60.6 [53.3; 67.4]). The main inclusion criteria were essential AH, age 18-79 years, insufficient response to previous AHT (clinical systolic blood pressure (SBP) >140–179 mm Hg). The study duration was three months. The following parameters were evaluated: dynamics of clinical and ambulatory BP (BP self-monitoring (BPSM); frequency of achieving the first goal of Results The TC group had a more severe condition at baseline by clinical parameters and history and had higher baseline BP, which made difficult the intergroup comparison. Nevertheless at three months, the decrease in clinical SBP was more pronounced in the TC group (from 162.1 to 126.8 mm Hg, Δ=35.7 mm Hg) than in the control group (from 157.8 to 128.4 mm Hg, Δ=29.4 mm Hg). 87.8% of patients in the TC group and 81.9 % (р=0.012) in the control group achieved the first BP goal of 180 mm Hg. The TC treatment was associated with a pronounced antihypertensive effect with respect of BPSM values, improved QoL, and renal function. Significant decreases in BP and achievement of BP goals by a vast majority of patients receiving TC were also observed in subgroups with DM or IGT, overweight and/or obesity, and CKD. AEs were observed during the treatment only in 8 patients (0.64 %), which confirmed good tolerability and high safety of the therapy.Conclusion The study results demonstrated a therapeutic effect of the amlodipine/indapamide/perindopril arginine fixed-dose combination (Triplixam®). This effect was evident as control of clinical BP with any baseline BP level, including different ranges of increased SBP, in AH combined with DM, IGT, obesity, and CKD, which offers advantages over a subjective choice of AHT. TC improved BPSM values, QoL indexes, provided nephroprotection, and was well tolerated.

Aim To evaluate the prevalence of residual symptoms in patients hospitalized for novel coronavirus infection at 8 months after discharge and the severity of such symptoms depending on demographic characteristics, concurrent diseases, and specific features of the acute period of COVID-19.Material and methods This study included the patients who were managed for novel coronavirus infection in a COVID-19 hospital and provided their consent to participate in the study (98 patients). At 8 months after discharge from the hospital, a structured telephone interview was performed.Results Only 40 % of patients treated for COVID-19 did not have any complaints at 8 months after discharge from the hospital. The most frequent complaints in the long term were fatigue (30.5 %), weakness (28.4 %), shortness of breath (23.2 %), arthralgia (22.1 %), myalgia (17.9 %), and anosmia (15.8 %). The background of chronic diseases and obesity, percentage of lung damage according to CT data, and the requirement for oxygen support during the acute period in our sample were not related with the presence of symptoms in the long term. The presence and severity of symptoms during the long term were not determined by the clinical condition, volume of lung damage, or requirement for oxygen support but were related with the gender and severity of inflammation upon admission.Conclusion Independent predictors for persistence of symptoms in the patient sample with severe novel coronavirus infection during the long term included chest and joint pain during the stay in the hospital, female gender, and increased levels of C-reactive protein upon admission.

Aim The aim of the study was evaluation of the effect of the coenzyme Q10 (Q10) treatment on all-cause and cardiovascular mortality of patients with chronic heart failure (CHF). Q-10 increases the electron transfer in the mitochondrial respiratory chain and exerts anti-inflammatory and antioxidant effects. These effects improve the endothelial function and reduce afterload, which facilitates the heart pumping function. Patients with reduced left ventricular (LV) ejection fraction (EF) (CHFrEF) have low Q10.Material and methods Criteria of inclusion in the meta-analysis: 1) placebo-controlled studies; 2) enrollment of at least 100 patients; 3) publications after 2010, which implies an optimal basic therapy for CHF; 4) duration of at least 6 months; 5) reported cardiovascular and/or all-cause mortality; 6) using sufficient doses of Q10 (>100 mg/day). The search was performed in CENTRAL, MEDLINE, Embase, Web of Science, E-library, and ClinicalTrials.gov databases. All-cause mortality was the primary efficacy endpoint in this systematic review and the meta-analysis. The secondary endpoint was cardiovascular mortality. Meta-analysis was performed according to the Mantel-Haenszel methods. The Cochrane criterion (I2) was used for evaluation of statistical heterogeneity. The random effects model was used at I2≥50 %, whereas the fixed effects model was used at I2Results Analysis of studies published from 01.01.2011 to 01.12.2021 identified 357 publications, 23 of which corresponded to the study topic, but only 6 (providing results of four randomized clinical trials, RCT) completely met the predefined criteria. The final analysis included results of managing 1139 patients (586 received Q10 and 553 received placebo). Risk of all-cause death was analyzed by data of four RCTs (1139 patients). The decrease in the risk associated with the Q10 treatment was 36 % (OR=0.64, 95 % CI 0.48–0.87, р=0.004). The heterogeneity of studies was low (Chi2=0.84; p=0.84; I2=0 %). Risk of cardiovascular mortality was analyzed by data of two RCTs (863 patients). The decrease in the risk associated with the Q10 treatment was significant, 55% (OR=0.45, 95 % CI: 0.32–0.64, р=0.00001). In this case, the data heterogeneity was also low (Chi2=0.41; p=0.52; I2=0 %).Conclusion The meta-analysis confirmed the beneficial effect of coenzyme Q10 on the prognosis of patients with CHFrEF receiving the recommended basic therapy.

Aim To study true prevalence of atrial fibrillation (AF) in a representative sample from the European part of the Russian Federation; to describe characteristics of patients with AF; and to provide the frequency of anticoagulant treatment.Material and methods Cross-sectional data of the EPOCH epidemiological study (2017) were used. Data were collected in 8 constituent entities of the Russian Federation; the sample size was 11 453 people. The sample included all respondents who had given their consent for participation and were older than 10 years. Statistical tests were performed in the R system for statistical data analysis.Results The prevalence of AF in the representative sample from the European part of the Russian Federation was 2.04 %. The AF prevalence increased with age and reached a maximum value of 9.6% in the age group of 80 to 89 years. The AF prevalence among females was 1.5 times higher than among men. With age standardization, the AF prevalence was 18.95 and 21.33 per 1,000 people for men and women, respectively. The AF prevalence increased in the presence of concurrent cardiovascular diseases (CVDs) or diabetes mellitus as well as with an increased number of comorbidities in the same person and reached 70.3 and 60.0 % in patients with 4 and 5 comorbidities, respectively. Patients with AF had a greater number of comorbidities and higher CHA2DS2VASc scores (5.0 vs. 2.0, pConclusion The AF prevalence in the European part of the Russian Federation was 2.04 %; it increased with age and in patients with concurrent CVDs or diabetes mellitus. Most of AF patients (93.2 %) required a mandatory treatment with oral anticoagulants.

Analysis of androgen status in men hospitalized with a moderate COVID-19 and its relationship with the severity of the disease.The study included 152 males with a confirmed diagnosis of COVID-19 based on the results of a positive PCR for the SARS-CoV-2 virus and/or computed tomography of the lungs hospitalized at the MSU University Clinic due to the moderate and severe COVID-19. Examination of the level of biochemical blood parameters (CRP, creatinine, urea, glucose, total testosterone (T)); CT of the lungs. To objectify the severity of the clinical symptoms, the NEWS2 distress syndrome severity scales and the original scale for assessing the clinical condition of patients with COVID 19 (SHOCS-COVID) were used.The median T level in 152 examined patients was 2.14 [1.21; 3.40] ng/ml. In patients with a T level below the median, the CRP level was more than two times higher, and the D-dimer value was almost two times higher than in patients with T level above median. The duration of treatment in the hospital was longer in men with COVID 19 and an initial T level below the median than in patients with T about the median (13 days vs 10.5 days, p=0.003). Low T level was correlated with lung damage by lung CT. After improving the clinical condition, there was a linear increase in the level of T independent of its initial level.Among men with moderate and severe COVID-19, a decreased testosterone level is detected in 46.7% of cases. Patients with low testosterone levels on admission have more severe COVID-19. A significant increase in testosterone level was observed after successful COVID-19 treatment without any special action regarding testosterone level.

Aim Optimal combination therapy for chronic heart failure (CHF) currently implies the mandatory use of at least four classes of drugs: renin-angiotensin-aldosterone (RAAS) system inhibitors or angiotensin receptor blocker neprilysin inhibitors (ARNI); beta-adrenoblockers (BAB); mineralocorticoid receptor antagonists; and sodium-glucose cotransporter 2 inhibitors. Furthermore, many of these drugs are able to decrease blood pressure even to hypotension and alleviate tachycardia. This study focused on the relationship of 24-h blood pressure (BP) and heart rate (HR) with the prognosis for CHF patients with sinus rhythm and left ventricular ejection fraction (LV EF) Material and methods Effects of clinical data, echocardiographic parameters, 24-h BP, and heart rhythm (data from 24-h BP and ECG monitors) on the prognosis of 155 patients with clinically pronounced CHF, LV EF Results The one-factor analysis showed that the prognosis of CHF patients was statistically significantly influenced by the more severe functional class (FC) III CHF compared to FC II, reduced LV EF (71 bpm vs. 103 mm Hg), and the lowest death rate of 15.3 %; the group with increased HR (>69 bpm) but preserved SBP (30.3 % of all patients) where the death rate was 44.7 %, which was significantly higher than in the first group; the group with normal HR (≤69 bpm) but reduced SBP (≤103 mm Hg) (16.1 % of patients) where the death rate was 40 %, which was comparable with the second group and significantly worse than in the first group; and the group with both increased HR (>69 bpm) and reduced SBP (≤103 mm Hg) (15.5 % of patients), which resulted in the maximal risk of death (70.8 % of patients with CHF and LV EF Conclusion Low SBP (including 24-h SBP with reduced variability in day- and nighttime) in combination with high HR (including by data of Holter monitoring), low LV EF, more severe clinical course of CHF, and the absence of an adequate treatment with neurohormonal modulators (RAAS inhibitors and BAB) significantly increased the risk of death. Isolating four types of FC II-III CHF with sinus rhythm and EF

Introduction The aim of this study was to assess the efficacy and safety of a combination of bromhexine at a dose of 8 mg 4 times a day and spironolactone 50 mg per day in patients with mild and moderate COVID 19.Material and methods It was an open, prospective comparative non-randomized study. 103 patients were included (33 in the bromhexine and spironolactone group and 70 in the control group). All patients had a confirmed 2019 novel coronavirus infection (COVID 19) based on a positive polymerase chain reaction (PCR) for SARS-CoV-2 virus RNA and/or a typical pattern of viral pneumonia on multispiral computed tomography. The severity of lung damage was limited to stage I-II, the level of CRP should not exceed 60 mg / dL and SO2 in the air within 92-98%. The duration of treatment is 10 days.Results The decrease in scores on the SHOKS-COVID scale, which, in addition to assessing the clinical status, the dynamics of CRP (a marker of inflammation), D-dimer (a marker of thrombus formation), and the degree of lung damage on CT (primary endpoint) was statistically significant in both groups and differences between them was not identified. Analysis for the group as a whole revealed a statistically significant reduction in hospitalization time from 10.4 to 9.0 days (by 1.5 days, p=0.033) and fever time from 6.5 to 3.9 days (by 2.5 days, pConclusion The combination of bromhexine with spironolactone appeared effective in treating a new coronavirus infection by achieving a faster normalization of the clinical condition, lowering the temperature one and a half times faster, and reducing explanatory combine endpoint the viral load or long duration of hospitalization (≥ 10 days).

Aim Development of a novel scale for assessing medical state in patients with new coronavirus infection based on clinical and laboratory disease severity's markers, named SHOKS-COVID scale.Material and Methods Clinical Assessment Scale (SHOKS-COVID) is based on1: clinical parameters (respiratory rate, Body temperature, SpO2 need and type of ventilation support) 2: Inflammation markers (C reactive protein (CRP) and prothrombotic marker (D-dimer)) and 3: percent of lungs injury by CT. This scale was used in several clinical studies in patients with varying severity of the course of the COVID 19. SHOKS-COVID scale was also compared against some additional biomarkers and with length of hospital stay.Results In patients with severe COVID-19 (Clinical Trial WAYFARER - 34 patients), SHOKS-COVID scores were correlated with the degree of inflammation: CRP (r = 0.64; p Conclusion Here we report a novel scale of COVID 19 disease progression. This scale ranges from zero in asymptomatic patients (with normal range of biomarkers and without lung damage on CT) to fifteen in extremely severe patients. The scores for SHOKS-COVID are increasing, in parallel with the deterioration of all other biomarkers of severity and prognosis in patients with new coronavirus infection. Based on the analysis carried out, we were able to determine values of SHOKS-COVID scale and levels of main clinical and laboratory markers in patients with different severity of COVID 19.

The document focuses on key issues of diuretic therapy in CHF from the standpoint of current views on the pathogenesis of edema syndrome, its diagnosis, and characteristics of using diuretics in various clinical situations.

The article is devoted to the treatment of the new coronavirus infection (COVID-19) in the advanced stages of the disease. The types of response of the immune system to the viral load of SARS-CoV-2 with the start of the inflammation process are considered. The situation is analyzed in detail in which the growing autoimmune inflammation (up to the development of a "cytokine storm") affects not only the pulmonary parenchyma, but also the endothelium of the small vessels of the lungs. Simultaneous damage to the alveoli and microthrombosis of the pulmonary vessels are accompanied by a progressive impairment of gas exchange, the development of acute respiratory distress syndrome, the treatment of which, even with the use of invasive ventilation, is ineffective and does not really change the prognosis of patients with COVID-19. In order to interrupt the pathological process at the earliest stages of the disease, the necessity of proactive anti-inflammatory therapy in combination with active anticoagulation treatment is substantiated. The results of the first randomized studies on the use of inhibitors of pro-inflammatory cytokines and chemokines (interleukin-6 (tocilizumab), interleukin-17 (secukinumab), Janus kinase blockers, through which the signal is transmitted to cells (ruxolitinib)), which have potential in the early treatment of COVID- 19. The use of a well-known anti-inflammatory drug colchicine (which is used for gout treatment) in patients with COVID-19 is considered. The design of the original COLORIT comparative study on the use of colchicine, ruxolitinib and secukinumab in the treatment of COVID-19 is presented. Clinical series presented, illustrated early anti-inflammatory therapy together with anticoagulants in patients with COVID-19 and the dangers associated with refusing to initiate such therapy on time.

Introduction Coronavirus pneumonia not only severely affects the lung tissue but is also associated with systemic autoimmune inflammation, rapid overactivation of cytokines and chemokines known as “cytokine storm”, and a high risk of thrombosis and thromboembolism. Since there is no specific therapy for this new coronavirus infection (COVID-19), searching for an effective and safe anti-inflammatory therapy is critical.Materials and methods This study evaluated efficacy and safety of pulse therapy with high doses of glucocorticosteroids (GCS), methylprednisolone 1,000 mg for 3 days plus dexamethasone 8 mg for another 3-5 days, in 17 patients with severe coronavirus pneumonia as a part of retrospective comparative analysis (17 patients in control group). The study primary endpoint was the aggregate dynamics of patients’ condition as evaluated by an original CCS-COVID scale, which included, in addition to the clinical status, assessments of changes in the inflammation marker, C-reactive protein (CRP); the thrombus formation marker, D-dimer; and the extent of lung injury evaluated by computed tomography (CT). Patients had signs of lung injury (53.2 % and 25.6 %), increases in CRP 27 and 19 times, and a more than doubled level of D-dimer (to 1.41 µg/ml and 1.15 µg/ml) in the active therapy and the control groups, respectively. The GCS treatment group had a more severe condition at baseline.Results The GCS pulse therapy proved effective and significantly decreased the CCS-COVID scores. Median score difference was 5.00 compared to the control group (р=0.011). Shortness of breath considerably decreased; oxygen saturation increased, and the NEWS-2 clinical status scale scores decreased. In the GCS group, concentration of CRP significantly decreased from 134 mg/dl to 41.8 mg/dl (р=0.009) but at the same time, D-dimer level significantly increased from 1.41 µg/ml to 1.98 µg/ml (р=0.044). In the control group, the changes were nonsignificant. The dynamics of lung injury by CT was better in the treatment group but the difference did not reach a statistical significance (р=0.062). Following the GCS treatment, neutrophilia increased (р=0.0001) with persisting lymphopenia, and the neutrophil/lymphocyte (N/L) ratio, a marker of chronic inflammation, increased 2.5 times (р=0.006). The changes in the N/L ratio and D-dimer were found to correlate in the GCS pulse therapy group (r =0.49, p=0.04), which underlined the relationship of chronic autoimmune inflammation with thrombus formation in COVID-19. No significant changes were observed in the control group. In result, four patients developed venous thromboembolic complications (two of them had pulmonary artery thromboembolism) after the GCS pulse therapy despite the concomitant antiplatelet treatment at therapeutic doses. Recovery was slower in the hormone treatment group (median stay in the hospital was 26 days vs 18 days in the control group, р=0.001).Conclusion Pulse therapy with high doses of GCS exerted a rapid anti-inflammatory effect but at the same time, increased the N/L ratio and the D-dimer level, which increased the risk of thromboembolism.

Aim.To perform a repeated epidemiological study of a representative sample in the European part of the Russian Federation in 2017 and to compare the dynamics of arterial hypertension (AH) prevalence with the effectiveness of blood pressure (BP) control in the population compared to 1998, 2002, and 2007.Materials and methods.A representative sample of the European part of the Russian Federation was created in 2002 and re-examined in 2007 and 2017. In 1998, a pilot project was performed for examining a representative sample for the Nizhniy Novgorod region.Results.During 19 years of follow-up, the AH prevalence increased from 35.5 to 43.3%. Te awareness and treatment coverage reached 76.9 and 79.3%, respectively, in 2017. Achievement of the target BP with a single measurement also increased among patients receiving antihypertensive medication from 14.3 to 34.9%. For the treatment of AH, medium-acting antihypertensive drugs are used, ofen at suboptimal doses.Conclusion.Epidemiological indices of awareness, treatment coverage, and number of effectively managed patients with AH have improved. However, the AH prevalence has increased by 7.8% for 19 years, which indicates inefciency of the primary prevention of this disease.

The review addressed the relationship of coronavirus disease 2019 (COVID-19) with functioning of the renin-angiotensin-aldosterone axis and the causes for unfavorable prognosis depending on patients’ age and comorbidities. The authors discussed in detail potential effects of angiotensin-converting enzyme inhibitors and angiotensin II type 1 receptor antagonists on the risk of infection and the course of COVID-2019 as well as the effect of SARS-COV2 virus on the cardiovascular system.

Aim.To investigate the difference in characteristics of patients admitted to the Tomsk National Research Medical Center with a diagnosis of heart failure (HF) in 2002 and 2016.Methods. Medical charts of all patients hospitalised in a single centre, with a diagnosis of HF, were included. Two three‑month periods were compared from January 2002 (n=210) and January 2016 (n=378).Results.Fewer patients with HF had symptoms or required diuretics in 2016 (63 % vs 98,6 %, pConclusion.Prescription rates for prognostic medications in HFrEF improved in 2016. The substantial percentage of patients diagnosed with HFpEF without symptoms or diuretic raises the question of whether a diagnosis of HF was appropriate in some cases.

This Conclusion of the Board of experts is devoted to the analysis of the evidence base, the position in modern clinical guidelines, the efficacy and safety analysis as well as the options of combined therapy with statins and ezetimibe (Otrio, JSC “AKRIKHIN”) in various categories of patients in routine clinical practice in theRussian Federation. Cardiovascular diseases (CVD) continue to lead in the structure of morbidity and mortality inRussia. Hypercholesterolemia is one of the main modifiable risk factors for CVD. Administration of HMGCo-A-reductase inhibitors (statins) remains the basis for the prevention and treatment of the main complications of atherosclerosis, but the achievement of target levels of LDL–C on of statin monotherapy in Russian practice among different categories of risk does not exceed 50%. Proportion of patients (up to 12%) does not tolerate statin therapy, which requires the search for alternative therapies. To optimize the control of the level of LDL–C, combination therapy with statins and ezetimibe is used. Ezetimibe is an effective lipid-lowering drug, an inhibitor of intestinal absorption of cholesterol, which was investigated in many international and Russian studies, the results of which have demonstrated good tolerability, safety and efficacy (reduction of LDL–C levels by 18% in monotherapy). It was noted that the combined therapy with low/medium doses of statins and ezetimibe effectively reduces the level of LDL–C by 44–53%, which is comparable to the effect of high doses of statins and reduces CV risk in patients with CKD and ACS. Otrio (INN Ezetimib) tablets 10 mg ( JSC “AKRIKHIN”,Russia) has demonstrated bioequivalence to the original drug Ezetrol tablets 10 mg (Schering-plough Labo N. V,Belgium). Broad use of a new generic product Otrio in combination with different statins will significantly increase the frequency of achievement of target lipid levels in patients with high and very high CV risk, including patients with chronic renal failure, type 2 diabetes and in patients with high hypercholesterolemia (LDL–C > 5 mmol/l) and, ultimately, reduce the burden of CV disease and mortality in Russia.

cardiovascular diseases, sudden cardiac death, risk, treatment, prevention Cardiovascular mortality in Russia is one of the highest in the world reaching 614 deaths per 100,000 annually. The main causes of death from cardiovascular diseases are the progression of congestive heart failure (about half of all cases) and sudden cardiac death (the other half). Thus, we can assume that the incidence of sudden cardiac death in 2016 was no less than 300,000. In the abbreviated version of the National Recommendations in English, the principles of decision-making algorithms in various clinical situations are used.
