[Prognostic value of periprocedural dynamics of left ventricular ejection fraction and subclinical pulmonary congestion in patients with myocardial infarction].

AIM: To assess the joint prognostic value of periprocedural dynamics of the left ventricular ejection fraction (PPD of LVEF) and subclinical pulmonary congestion during lung stress ultrasound in patients with first acute myocardial infarction (AMI) and percutaneous coronary intervention (PCI) in relation to the development of heart failure (HF) in the postinfarction period. MATERIALS AND METHODS: Our prospective, single-centre, observational study included 105 patients with a first MI with no HF in the anamnesis and successful PCI. All patients underwent standard clinical and laboratory tests, NT-proBNP level assessment, echocardiography, lung stress ultrasound with a 6-minute walk test. All patients had no clinical signs of heart failure at admission and at discharge. Criteria for PPD of LV EF: improvement in LV EF≥50%; ∆LV EF more than 5%, but LV EF<50%. According to the results of lung stress ultrasound, pulmonary congestion was diagnosed: mild (2-4 B-lines), moderate (5-9 B-lines) and severe (≥10 B-lines). The end point was hospitalization for HF for 2.5 years. RESULTS: Upon admission, LV EF of 50% or more was registered in 45 patients (42.9%). Positive PPD was registered in 31 (29.5%) patients. After stress ultrasound of the lungs, 20 (19%) patients had mild subclinical pulmonary congestion, 38 (36%) moderate and 47 (45%) severe according to the criteria presented. During the observation period, patients with no PPD of LVEF were significantly more likely to be hospitalized for the development of HF (in 44.4% of cases) compared with patients with positive PPD (in 15.2% of cases) and with initial LV EF≥50% (in 13.4% of cases; p=0.005). When performing logistic regression analysis, the best predictive ability was found in the combination of the absence of PPD of LV EF and the sum of B-lines ≥10 on exercise (relative risk 7.45; 95% confidence interval 2.55-21.79; p<0.000). CONCLUSION: Evaluation of the combination of PPD of LV EF and the results of stress lung ultrasound at discharge in patients with first AMI and successful PCI with no HF in anamnesis allows us to identify a high-risk group for the development of HF in the postinfarction period.

[Clinical and diagnostic value of including PCR blood test in the traditional algorithm for identifying causative agents of infective endocarditis: a cohort study of 124 patients].

BACKGROUND: If infective endocarditis (IE) is suspected, the determination of the etiology is of fundamental importance for the verification of the disease and the appointment of effective therapy. Microbiological diagnostic features are important, but they often need to be supplemented by culture-independent studies of pathological agents. AIM: To investigate of the diagnostic advantage and value of quantitative analysis of molecular biological methods (polymerase chain reaction - PCR, sequencing) in addition to microbiological examination of whole venous blood in IE. MATERIALS AND METHODS: We examined 124 patients with suspected or significant IE (DUKE 2015) hospitalized in the Vinogradov City Clinical Hospital (2015-2021). All patients underwent parallel microbiological (cultural) and molecular biological (PCR or PCR followed by sequencing) examination of venous whole blood samples. RESULTS: The introduction of an early parallel PCR study into the algorithm for the etiological diagnosis of IE made it possible to obtain an additional advantage in 43/124 (34.7%) patients, which made it possible to exclude unreliable results in the determination of CoNS skin commensals and pathogens atypical for IE or contamination and identify the true pathogens, and also for the first time to isolate the etiopathogenetic pathogen with a negative microbiological study. It was shown that in IE associated with CoNS, the association with the disease was confirmed by PCR in 21.4% (3/14) and refuted in 71.4% (10/14). The coincidence of the results of microbiological and PCR studies of blood samples was obtained only in 35/95 (36.8%). Positive results of PCR analysis of blood of biological material with negative results of culture were obtained in 22/51 (43.1%), of which 2/22 (9.0%) were able to confirm the presence of Bartonella spp DNA. The presented complex algorithm made it possible to significantly increase the possibility of intravital identification of the pathogen in the blood from 58.9 to 76.6%. IE with unknown etiology was present in 29/124 (23.4%) patients. A parallel PCR study allowed timely correction of antibiotic therapy in 43/124 (34.7%) patients. CONCLUSION: Expansion of indications for the use of PCR studies, primarily whole venous blood samples, is justified, not only in IE with negative results of microbiological examination, but also as a control method for the reliability of the results of traditional (cultural) diagnostic methods.

[Risk Assessment of Adverse Outcomes in Symptomatic Patients With Arterial Hypertension and Chronic Heart Failure With Preserved Ejection Fraction Using THE HFA-PEFF Algorithm].

Aim      To study the incidence of heart failure (HF) in patients with arterial hypertension (AH), symptoms of HF, and left ventricular ejection fraction (LV EF) ≥50 % using a novel, modified HFA-PEFF diagnostic algorithm and to evaluate the liver hydration status and density depending on the established HF profiles and the prognostic significance of this algorithm.Material and methods  This study included 180 patients (median age, 72 years) with AH, symptoms of HF, and LV EF ≥50 %. The incidence of chronic HF with preserved ejection fraction (CHFpEF) was studied with the stepwise, modified HFA-PEFF diagnostic algorithm, and long-term outcomes were assessed at 3, 6, and 12 months of follow-up. The hydration status was determined by a bioimpedance vector analysis, and the liver density was measured by indirect fibroelastometry. The following tests were performed for all patients: standard, general clinical and laboratory examination with evaluation of CH symptoms (including N-terminal pro-brain natriuretic peptide test); extended echocardiography with assessment of structural and functional parameters of the heart; a KCCQ questionnaire was used for evaluation of patients' condition and quality of life (QoL). Long-term outcomes were studied by phone calls at 3, 6, and 12 months following discharge from the hospital/visit (worsened QoL, repeated hospitalization for cardiovascular causes, cardiovascular death or all-cause death).Results The following profiles were determined by the HFA-PEFF algorithm: with CHFpEF, with intermediate probability of HF, and without HF (58.9, 31.1, and 10 %, respectively). The study showed that patients with CHFpEF compared to patients of the intermediate group and without HF, had higher levels of brain natriuretic peptide, more pronounced signs of congestion according to results of the bioimpedance vector analysis and a higher liver density according to results of indirect fibroelastometry of the liver, which allowed identification of a group of patients with a high probability of CHFpEF. The diagnosis of HF by HFA-PEFF had an adverse prognostic significance with respect of worsened QoL according to the KCCQ questionnaire, and of repeated admission for HF during a year.Conclusion      In AH patients with symptoms of HF and LV EF ≥50 %, CHFpEF was detected with the HFA-PEFF algorithm in 58.9 % of cases. Patients with AH and verified CHFpEF had a high incidence of hyperhydration and increased liver density. A diagnosis of CHFpEF by the HFA-PEFF algorithm had an adverse prognostic significance with respect of long-term outcomes.

[Prevalence and clinical associations of iron deficiency in patients with decompensated heart failure, depending on the diagnostic criteria used for iron deficiency].

AIM: To compare the frequency of iron deficiency (ID) in patients with decompensated heart failure (HF), defined by international guideline criterion ferritin 100 ng/ml or ferritin from 100 to 299 ng/ml with TSAT20% (criterion A) and by bone marrow biopsy criterion TSAT19.8% and serum iron 13 mol/l (criterion B); to evaluate the effect of ID, diagnosed on the basis of different ID criteria, on NT pro-BNP, sST2, CRP levels and New York Heart Association (NYHA) functional classes (FC) distribution between groups with ID and without ID. MATERIALS AND METHODS: The study included 223 patients (median age 73 [65; 82] years, 58% males) who were hospitalized to V.V. Vinogradov Moscow City Clinical Hospital No. 64 with decompensated HF. All patients underwent a standard physiological examination, laboratory and instrumental studies, including determination of NT-proBNP, sST2, CRP, and ferrokinetic parameters (serum iron, transferrin, ferritin). TSAT was calculated as: serum iron / transferrin 3.98. NYHA FC was determined according to Heart Failure Severity Rating Scale score. All patients underwent echocardiography to assess the ejection fraction of the left ventricle. RESULTS: According to criterion A ID was detected in 89% (n=199) of patients. There were no significant differences between levels of CRP, NT-proBNP and sST2. According to criterion B ID was detected in 70% (n=156) of patients. In the ID group, higher levels of CRP (15.1 mg/l vs 6.2 mg/l, p0.001), NT-proBNP (5422 pg/ml vs 2380 pg/ml, p0.001) and sST2 (59.6 ng/ml vs 42 ng/ml, p=0.02) were detected. Intravenous FCM admission according to current international guidelines (diagnosis of ID according to criterion A) is recommended to 57% of patients included in this study. Both methods formed groups with ID, in which patients had higher NYHA FC compared to groups without ID. According to current clinical guidelines, iron deficiency should be assessed according to method 1. More than half of patients (57, n=127) have indications for intravenous FCM to reduce risk of HF hospitalizations. CONCLUSION: The frequency of ID in patients with decompensated heart failure varies from 70 to 89% depending on the criterion used to diagnose ID, but in any case, remains high. Intravenous FCM should be prescribed in 57% (n=127) of patients. Criterion B, validated against the gold standard of diagnostics, unlike criterion A, makes it possible to form groups of patients with ID and without ID, significantly differing in CRP, NT-proBNP, and sST2 levels.

Prognostic Value of Admission-to-Discharge Change in Integral Congestion Assessment for Predicting Adverse Outcomes in Patients with Decompensated Heart Failure.

This study was performed to evaluate the prognostic value of relative changes from admission to discharge (Δ%) of integrated congestion assessment to predict adverse outcomes in patients with irreversible heart failure (HF) during a one-year follow-up. The study included 122 patients (60% males, median age of 69 years) with decompensated HF. Most of the patients (92%) had a history of arterial hypertension, 53.3% had coronary heart disease, and 40.2% had type 2 diabetes mellitus. All patients underwent assessments, including NT-proBNP, lung ultrasound (LUS) B-line score, liver stiffness by transient elastography, and resistance and reactance by bioimpedance vector analysis (BIVA). The assessments were performed at admission and discharge, and a relative change from admission (delta percentage, Δ%) was calculated. Long-term clinical outcomes were assessed by a structured interview conducted 1, 3, 6, and 12 months after discharge. The cut-offs for the occurrence of the endpoint events were Δ% NT-proBNP of ≥ -25, Δ% liver stiffness of ≥ -44, Δ% B-line score on lung ultrasound of ≥ -73, Δ% BIVA resistance of ≤ 18, and Δ% BIVA reactance of ≤ 40. It was revealed that 55% of endpoint events, including 22 (18%) deaths and 33 (27%) readmissions, occurred within a median of 74 days (interquartile range: 33-147). Patients with an endpoint event had significantly worse values of all studied parameters in contrast to patients without it. There was a significant direct association between Δ% NT-proBNP and Δ% B-lines (r=0.18; P=0.04), and a highly reliable inverse association was observed between Δ% liver stiffness and Δ% BIVA reactance (r=-0.4; P<0.001). No significant associations were found between the other parameters. Univariate Cox regression analysis demonstrated the independent prognostic value of all congestion markers under study (NT-proBNP, LUS B-lines, liver stiffness, and BIVA reactance) for predicting the combined endpoint. Multivariate Cox regression analysis confirmed the independent prognostic value in predicting the risk of endpoint event for the following parameters: NT-proBNP (hazard rate [HR] 2.5, P=0.001), liver stiffness (HR 2.3, P=0.012), LUS B-line score (HR 2.2, P=0.008). However, it did not find any significant prognostic value for BIVA resistance and reactance. The relative admission-to-discharge change in the integral assessment of congestion had a prognostic value for predicting the risk of adverse outcomes (all-cause mortality and readmission rate) in patients with decompensated HF during a one-year follow-up.

[Prognostic value of liver stiffness in decompensated heart failure: results of prospective observational transient elastography-based study].

OBJECTIVE: There is growing evidence that liver stiffness (LS) in decompensated heart failure (DHF) is related to congestion, however data about its impact on outcomes are limited. The aim of the study was to evaluate associations and long-term prognostic significance of LS measured by transient elastography (TE) in DHF. METHODS: Single-center prospective observational study of 194 patients hospitalized with DHF, of whom 71 % were male, 68 ± 11 years (mean ± SD), had a left ventricular ejection fraction of 39±14%. LS by TE (FibroScan 502, Echosens, France) was measured on admission (n=176) and/or discharge (n=165). Outcomes of interest were all-cause death or heart transplantation, heart failure (HF) rehospitalisation, heart valve repair surgery. Outcome analysis was performed with Kaplan-Meier survival curves compared by log-rank test and with Cox proportional hazards regression. RESULTS: Median LS on admission and discharge were 11.1 (interquartile range 6.3;22.9) and 8.2 (5.8;14.0) kPa, respectively. Higher LS was associated with more clinical congestion on admission and discharge. Patients with LS on admission ≥11.1 kPa and at discharge ≥8.2 kPa were characterised by more pronounced clinical and echocardiographic signs of right-sided HF. Total of 5 (2.6%) patients died in hospital. Further, 31 (17.3%) deaths, 1 (0.6%) heart transplantation, 3 (1.7%) valve repair surgeries and 54 (30.2%) HF rehospitalizations occurred during follow-up (median 183 days). LS ≥ median was associated with higher probability of HF rehospitalizations and composite end point (all-cause death, heart transplantation, HF rehospitalisation and valve replacement therapy) both on admission (logrank p=0.004 and p=0.006) and at discharge (log-rank p=0.001 and p=0.004). Multivariable Cox regression analysis revealed that on a continuous scale LS increase per 1 kPa on admission was related to higher risk of HF hospitalization (hazard ratio [HR] 1.024, 95% confidential interval [CI] 1.002-1.046, p=0.03). LS at discharge was independently associated with increased all-cause mortality (HR per 1 kPa increase 1.098, 95% CI 1.025-1.176, p=0.008), higher risk of HF hospitalization (HR 1.075, 95% CI 1.035-1.117, p.

AIM: to assess antihypertensive efficacy of the fixed-dose amlodipine/indapamide/perindopril arginine combination in hypertensive patients in real clinical setting. METHODS: We included in the 3­month clinical program 1 599 patients with arterial hypertension (AH) (38.8 % men, mean age 61.6±10 years). Primary outcomes were change of office and ambulatory (home blood pressure monitoring) systolic and diastolic blood pressure (SBP and DBP) from baseline to 3 months and rate of achievement of target BP.

[Characteristics and clinical associations of arterial stiffness and subclinical atherosclerosis in patients with rheumatoid arthritis].

Te aim of the study was to evaluate parameters of arterial stiffness (AS) (carotid-femoral pulse wave velocity (cf PWV), central pulse pressure (PP), cardio-ankle vascular index (CAVI) and stiffness gradient between aorta and brachial artery) and subclinical atherosclerosis (carotid intima-media thickness (CIMT) and ankle-brachial index (ABI)) according to inflammatory activity in patients with R. MATERIALS AND METHODS: 85 patients with R (EULAR/ACR 2010) were examined (age 59,7±14,3 years, 64,7% with arterial hypertension (AH). Median duration of R was 7 years. PWV and central pulse wave were assessed by applanation tonometry. Arterial stiffness gradient was calculated as a ratio between carotid-femoral and carotid-radial PWV: its elevation ≥1 was considered as arterial stiffness mismatch. ABI and CAVI were measured by sphygmometry. CIMT was assessed according to the standard protocol, CIMT≥0,9 mm was considered as a subclinical marker of atherosclerosis. p.

[The Value of Right Ventricular Dysfunction and Right Ventricular-Pulmonary Artery Coupling in Chronic Heart Failure: The Role of Echocardiography].

In this review article we discuss the clinical and prognostic value of echocardiographic evaluation methods of the right ventricular function and right ventricular - pulmonary artery coupling, advantages and disadvantages of echocardiography in comparison with other instrumental methods of investigation in patients with chronic heart failure.

[Experience of hospital initiation of sacubitril/valsartan in a female patient after acute decompensated heart failure].

The article discusses management of a female patient with chronic heart failure with reduced left ventricular ejection fraction after an episode of acute decompensation. Replacing an angiotensin-converting enzyme inhibitor with a representative of a new angiotensin receptor-neprilysin inhibitor class, sacubitril/valsartan, in the combination therapy allowed fast achievement and maintenance of the compensation state. The treatment was well tolerated and was not associated with clinically significant adverse effects.

[Practical aspects of anticoagulant therapy in patients with atrial fibrillation and arterial hypertension].

Atrial fibrillation (AF) represents the most frequent sustained cardiac arrhythmia, the prevalence of AF is 1-2 % in the general population and up to 6 % for population over 80 years. Arterial hypertension (AH) is the commonest background comorbidity in patients with AF. Patients with AF have 3-6­fold increased risk of ischemic stroke in comparison to that in general population, additionally the presence of AH leads an 2-3­fold increase in risk of subsequent stroke. Current clinical guidelines recommend long-time anticoagulant treatment for prevention of stroke and thromboembolic complications in majority of patients with confirmed AF. Not only does uncontrolled high blood pressure contribute to developing new-onset AF or AF progression but also can increase a bleeding risk related to oral anticoagulants. Patients with AF and concomitant AH resulting in target organ damage need for more favorable safety profile of oral anticoagulants. Instruction label dabigatran treatment in two doses can individualize approach to choice of long-term anticoagulation with lower risk of major bleeding in AF patients.

[Problems of anticoagulation therapy in patients with chronic heart failure and atrial fibrillation: role of rivaroxaban].

Heart failure and atrial fibrillation are the two new epidemics of cardiovascular disease. Their frequent coincidence increases mortality rates mainly because of increased risk of thromboembolic events. The review focuses on epidemiology, mechanisms, prognosis in patients with heart failure and atrial fibrillation, approaches to the administration of direct oral anticoagulants and role of rivaroxaban.

[Deficit of Magnesium and States of Hypercoagulation: Intellectual Analysis of Data Obtained From a Sample of Patients Aged 18-50 years From Medical and Preventive Facilities in Russia].

The states characterized by pronounced hypercoagulable components (deep vein thrombosis, cardio- and cerebro-vascular pathologies) are caused by multiple pathophysiological factors, including insufficient supply of magnesium (Mg) and other micronutrients. AIM: to present results of analysis of the Institute of Microelements Data Base (IMDB) performed from point of view of interrelationships of Mg deficit and hypercoagulable states in adults treated in medico-preventive facilities of Central, Northwestern, Northern, and Siberian federal districts of Russia. METHODS: The analysis was realized as analysis of data obtained in a cross-sectional study. In the cohort of patients (n=1453) formed from the IMBD adequacy of Mg supply was assessed by magnesium levels in blood plasma (Mg BP) (0.69±0.15 mmol/L) and estimates of daily Mg consumption according to dietary diaries (Mg D) (185±90 mg/day). RESULTS: Mg supply was adequate (Mg BP >0.80 mmol/L, Mg D >300 mg/day) in not more than 6 % of patients. Presence of "Hypercoagulation" label in data base was associated with greater number of chronic diseases (2.3±2.1 and 0.83±0.8 with and without this label, respectively, р=0.0006) and elevated risk of the presence on 4 comorbid pathologies (odds ratio [OR] 18, 95 % confidence interval [CI] 10-25, р=0.0006). Mg deficit (Mg BP.

Infective Endocarditis in Moscow General Hospital: Clinical Characteristics and Outcomes (Single-Center 7 Years' Experience).

AIM: to investigate clinical properties of course and outcomes of infective endocarditis (IE) depending on source of infection, to find predictors of mortality in a Moscow general hospital. MATERIALS AND METHODS: We included in this study 176 patients with definite and possible infective endocarditis (the Duke criteria), admitted in our hospital in 2010-2017. Patients were divided in three groups according to source of infection. All patients underwent standard clinical and laboratory assessment, echocardiography, blood culture test combined with blood PCR with sequencing. Inhospital and 1-year outcome were evaluated. RESULTS: Among 176 patients with IE 65.3 % were men (median age 57 [35-72] years), most patients (n=149, 84.7 %) had native valve IE. Etiological factor was identified in 127 (72.2 %) cases. Gram-positive infective agents prevailed (54 %). Surgery in active phase of the disease was performed in 30 (17 %) patients. Among patients with healthcare-associated IE (n=76, 43.9 %) prevailed those older than 60 years, with high Charlson comorbidity index, with culture-negative IE, and complicated clinical course (mainly progressing heart failure). Patients with intravenous drug use associated IE (n=50, 28.4 %) had low Charlson index, association with hepatitis C viral infection, involvement of tricuspid valve with big vegetations, high frequency of embolic complications, and low inhospital mortality. Group of patients with community acquired IE (n=50, 28.4 %) more often had uncommon causative microorganisms, and had better long-term outcome. In-hospital mortality was 30.1 % (n=53) mostly due to sepsis with multi-organ failure, and heart failure. Risk factors of inhospital death were history of cardiovascular diseases, old age, kidney damage, methicillin-resistant Staphylococcus aureus (MRSA) infection, uncontrolled infection, and embolic events. Risk factors of 1-year mortality were history of stroke, and heart failure as IE complication. Independent predictors of in-hospital death were MRSA infection (odds ratio [OR] 50.32, 95 % confidence interval [CI] 1.66-213.92; p=0.002), persistent infection (OR 18.6, 95 %CI 5.37-64.40; p=0.001), duration of fever >7 days after initiation of antibacterial therapy (OR 13.41, 95 %CI 3.51-51.24; p=0.001); and of death during first year - history of cerebral infarction (OR 4.39, 95 %CI 1.32-14.70; p=0.016)), and heart failure as IE complication (OR 8.1, 95 %CI 1.97-67.09; p=0.016). Among patients subjected to surgery there were no fatal outcomes during 1 year after hospital discharge, while among conservatively treated patients were 21 (14.4 %) deaths (p<0.009). CONCLUSION: Main clinical features of IE course in patients urgently admitted to a general hospital was dominance of healthcare-associated  IE among patients, who were older than 60 years with severe comorbidities. These patients had more complications and worse outcome. Modeling of prognosis identified uncontrolled infection as key factor of unfavorable outcome. Surgery significantly reduced long-term mortality.

AIM: To study effects of a fixed azilsartan medoxomil/chlorthalidone combination (Edarbi Clo) on clinical, ambulatory and central blood pressure (BP) in patients with uncontrolled arterial hypertension (AH)). MATERIALS AND METHODS: Patients (n=25) with uncontrolled AH were given fixed azilsartan medoxomil/chlorthalidone combination (40 / 12.5 mg / day) for 4 weeks. After 4 weeks, in patients who did not achieve target BP levels the dose was increased up to 40 / 25 mg / day. Duration of the study was 12 weeks. RESULTS: After 12 weeks of treatment 88 % of patients achieved target clinical BP (.

[Prevalence of Markers of Chronic Kidney Disease in Patients With Arterial Hypertension: Results of Epidemiological Study CHRONOGRAF].

In an noninterventional observational open multicenter program CHRONOGRAF the prevalence of markers of chronic kidney disease (CKD) was studied in 1600 patients with arterial hypertension with and without type 2 diabetes mellitus. Glomerular filtration rate (GFR) was calculated (CKD­EPI formula) and albuminuria (AU) was determined as albumin/creatinine (A/Cr) ratio in the morning portion of urine. In 49.4% of patients decreased GFR 30 mg/g was detected. Decrease of GFR 30 mg/g - in 32.6%, combination of reduced GFR and high/very high AU - in 18%. High or very high level of combined risk of progression to CKD and cardiovascular complications had 28.5% of patients.
