Introduction. Anemic syndrome (AS) is a common pathological condition in patients with chronic heart failure (CHF) and is recognized as an independent predictor of poor prognosis. A particular role is played by pathogenetically associated with CHF anemia. Mechanisms of its occurrence are being studied. An important role belongs to systemic inflammation, which is involved in the pathogenesis of anemia of chronic diseases (ACD). However, the contribution of cytokine-induced inflammation in patients with heart failure has not yet been fully investigated. Material and methods. A total of 873 cases of patients with CHF were prospectively analyzed on the basis of the cardiology department of the SBHCI NNR «Nizhny Novgorod Regional Clinical Hospital n.a. N.A. Semashko». The main group consisted of patients with anemia pathogenetically associated with heart failure (n = 96), the control group (CG) (n = 35) patients with heart failure without anemia. The indicators of ferrokinetics were assessed and the systemic inflammation was compared by indicators of interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and serum hepсidin. Results. Patients of the main group had signs of functional iron deficiency (ID) and significantly higher values of cytokines and hepsidin compared with the CG. The relationship between the level of cytokines and hepsidin with the severity of CHF, hemogobin and chronic kidney disease was revealed. Conclusion. An increase in the concentration of pro-inflammatory cytokines and hepcidin in patients with AS with decompensation of CHF is interrelated with functional ID and a decrease in hemoglobin level. This shows the role of cytokine-induced inflammation in the genesis of anemia in heart failure. The functional state of the kidneys makes a special contribution to these mechanisms. As CKD increases, the levels of inflammatory cytokines and hepcidin in these patients and their relationship with markers (CKD) increase.

Introduction: Malnutrition is a factor that defines vital prognosis in chronic heart failure. Objective: This study investigated nutritional and metabolic disorders in patients with heart failure by examining the association of severity of heart failure with inflammatory cytokines, appetite-regulating hormones, and energy metabolism. Methods: Subjects were 50 patients with heart failure. On admission, nutritional status was assessed, and biochemical blood tests were performed, including for serum tumor necrosis factor-α, interleukin-6, ghrelin, and leptin levels. Resting energy expenditure (REE) was also measured by indirect calorimetry to examine its association with severity of heart failure and levels of inflammatory cytokines and appetite-regulating hormones. Results: There were significant associations between serum brain natriuretic peptide (BNP) level and nutrition indices, indicating that nutritional status was worse when heart failure was more severe. Inflammatory cytokine levels showed significant positive correlations with BNP level. Measured REE/bodyweight was not associated with severity of heart failure, but was negatively correlated with body fat percentage and leptin levels. Conclusions: Energy metabolism was not associated with serum BNP level among patients with heart failure with New York Heart Association functional class up to III. Body fat percentage and leptin levels may be a good predictor of energy metabolism in patients with heart failure.

In order to assess the characteristics of the clinical manifestation of CHF with obesity, taking into account the polymorphism of the CYP2D6*4 gene of the cytochrome P450 system in terms of patient’s quality of life a prospective randomized controlled trial was conducted, 127 people (93 men and 34 women) aged 32-87 (61) years with CHF of II—III stages, 1^1 functional class according to the classification of the New York Heart Association (NYHA) have been examined. The main group consisted of 73 patients with obesity of 1 degree and higher, the comparison group consisted of 54 patients without obesity, the control group consisted of 21 people without cardiovascular disorders. Research methods included estimation of clinical symptom score scale, 6-minute walk test, quality of life (with the Minnesota questionnaire for patients with heart failure), assessment of subjective symptoms and course of the disease, anthropometric data, determination of objective signs of the disease; instrumental methods (Doppler echocardiography, basic laboratory examination, etc.), as well as genetic research (G1846A variants of the CYP2D6 gene real-time polymerase chain reaction), statistical non-parametric methods (with 0.05 p-value thresold). It is shown, that in the clinical aspect, patients of the main group have been characterized by a tendency to more expressive pathological manifestations of CHF, especially in carriers of the heterozygous GA variant of the CYP2D6*4 gene of the cytochrome P450 system. According to the Minnesota questionnaire, the clinical condition of patients and the quality of life in case of GG polymorphism variant was better than in GA carriers of the CYP2D6*4 genotype variant of the cytochrome P450 system.

The diagnosis of community-acquired pneumonia (CAP) with chronic heart failure (CHF) is associated with objective difficulties. Our case–control study aims to establish whether established serum inflammatory biomarkers are relevant to the diagnosis of CAP in patients with CHF. Seventy inpatients with previously diagnosed CHF and suspected non-severe CAP were recruited and then stratified into two subgroups with confirmed and rejected diagnosis of CAP. C-reactive protein (CRP), procalcitonin (PCT), tumor necrosis factor α (TNFα), interleukin-6 (IL-6) and brain natriuretic peptide (BNP) were measured. The value of biomarkers was determined using logistic regression, and their discriminatory efficacy was assessed by analyzing receiver operating characteristic (ROC) curves. Significantly higher levels of CRP 50.0 (35.5–98.5) mg/L, PCT 0.10 (0.05–0.54) ng/mL and IL-6 46.1(21.4–150.3) pg/mL in cases were identified as compared to the control group—15.0 (9.5–25.0) mg/L, 0.05 (0.05–0.05) ng/mL and 13.6 (9.5; 25.0) pg/mL, respectively. The Area Under the ROC Curve (95% CI) was the highest for CRP—0.91 (0.83–0.98), followed by PCT—0.81 (0.72–0.90) and IL-6—0.81 (0.71–0.91). A CRP value of >28.5 mg/L had an optimal sensitivity and specificity ratio (85.7/91.4%). In conclusion, the measurement of serum CRP, PCT and IL-6 levels can be useful for the diagnosis of CAP in patients with CHF. CRP showed optimal diagnostic utility in this population.

Although β-adrenoreceptor antagonists appear to be beneficial in chronic heart failure there is little information on their effects on autonomic and baroreceptor function which may have important prognostic implications. We sought to determine first whether β-adrenoreceptor blockade will improve baroreceptor function and vagal tone in chronic heart failure, and second whether there were any differences between standard therapy with metoprolol and the second-generation vasodilating β-blocker celiprolol. In this double-blind randomized placebo-controlled study 50 patients with stable chronic heart failure received either celiprolol 200 mg daily, metoprolol 50 mg twice daily or placebo for 12 weeks after a 4-week dose titration period. Thirty-five healthy normal subjects were also studied. Baroreceptor gain was assessed non-invasively by cross-spectral analysis of R–R and systolic blood pressure low- and high-frequency components (the α angle) during controlled respiration. High-frequency power was used as a measure of vagal modulation. Satisfactory recordings for analysis were obtained in 31 patients with heart failure. The results showed that at baseline baroreceptor gain (αHF) was significantly depressed in patients with heart failure compared with the normal control group (4.95±0.55 versus 11.73±1.32 ms/mmHg, P< 0.0001). After 12 weeks of treatment with metoprolol baroreceptor gain improved significantly whether measured while supine (P = 0.03) or standing (P = 0.009), and this was associated with a significant increase in R–R HF power (P = 0.008). There were no significant changes after treatment with celiprolol or placebo. We conclude that metoprolol but not celiprolol therapy restores baroreceptor gain towards normal and increases vagal tone in chronic heart failure. The ancillary properties of celiprolol do not appear to provide any advantages over metoprolol for the restoration of autonomic and baroreceptor function in heart failure.

Abstract Background Recent Cochrane Systematic Review suggested that the participation in cardiac rehabilitation is associated with approximately 20% lower cardiovascular mortality and morbidity. Exercise therapy is the key component of cardiac rehabilitation programs. In recent years, innovative technologies have been introduced into the field of rehabilitation, and a typical example is the wearable cyborg Hybrid Assistive Limb (HAL). The wearable cyborg HAL provides motion assistance based on detection of bioelectrical signals on the skin surface when muscle forces are generated. The lumbar-type HAL is expected to expand the therapeutic options for severe cardiac patients who have difficulty in performing usual cardiac rehabilitation programs, such as bicycle pedaling or walking. Purpose We aim to compare the efficacy of exercise therapy performed with motion assistance from a lumbar-type HAL versus conventional training (sit-to-stand exercise without HAL) in patients with chronic heart failure. Methods This clinical trial is a randomized, non-blinded, and controlled study. Twenty-eight heart failure patients (73.1±13.8 years) who have difficulty in walking at the usual walking speed of healthy subjects were randomly assigned to 2 groups (HAL group or control group) with a 1:1 allocation ratio and performed sit-to stand exercise either with HAL or without HAL for 5 to 30 minutes once a day, and 6 to 10 days during the study period. The brain natriuretic peptide (BNP), isometric knee extensor strength, standing ability (30-seconds chair-stand test: CS-30), short physical performance battery (SPPB) and 6-minute walking distance (6MWD) were measured before and after the completion of cardiac rehabilitation. Cardiac events such as death, re-hospitalization, myocardial infarction and worsening of angina pectoris and heart failure during 1 year after discharge were evaluated. Results There was no significant difference in the number of days of exercise therapy between the two groups. BNP, SPPB and 6MWD were improved in both groups. In the HAL group, the isometric knee extensor strength (0.29±0.11 vs 0.35±0.11 kgf/kg, p=0.003) significantly improved and CS-30 (5.5±5.1 vs 8.2±5.3, p=0.054) tended to improve. However, in the control group, either the isometric knee extensor strength (0.35±0.11 vs 0.36±0.14 kgf/kg, p=0.424) or CS-30 (6.0±4.3 vs 9.2±6.2, p=0.075) did not significantly change. HAL group showed significantly more improvement in the isometric knee extensor strength than control group (p=0.045). Cardiac events occurred in 20% in the HAL group and 43% in the control group. Conclusion The improvement in isometric knee extensor strength with the assistance from lumbar-type HAL suggests that exercise therapy using this device may be useful in chronic heart failure patients with flail or sarcopenia, a strong poor prognostic factor in these patients.

Purpose The results of a study to determine whether pharmacy team–led postdischarge intervention can reduce the rate of 30-day hospital readmissions in older patients with heart failure (HF) are reported. Methods A retrospective chart review was performed to identify patients 60 years of age or older who were admitted to an academic medical center with a primary diagnosis of HF during the period March 2013–June 2014 and received standard postdischarge follow-up care provided by physicians, nurses, and case managers. The rate of 30-day readmissions in that historical control group was compared with the readmission rate in a group of older patients with HF who were admitted to the hospital during a 15-month intervention period (July 2014–October 2015); in addition to usual postdischarge care, these patients received medication reconciliation and counseling from a team of pharmacists, pharmacy residents, and pharmacy students. Results Twelve of 97 patients in the intervention group (12%) and 20 of 80 patients in the control group (25%) were readmitted to the hospital within 30 days of discharge (p = 0.03); 11 patients in the control group (55%) and 7 patients in the intervention group (58%) had HF-related readmissions (p = 0.85). Conclusion In a population of older patients with HF, the rate of 30-day all-cause readmissions in a group of patients targeted for a pharmacy team–led postdischarge intervention was significantly lower than the all-cause readmission rate in a historical control group.

Background: The concept of ventricular-arterial coupling implies that LV-function is determined by the three factors left ventricular diastolic, left ventricular systolic and arterial elastance. We have previously documented an improvement in endothelial function and systolic LV-function in patients with chronic heart failure (CHF) after 6 months of exercise training (ET). It remains, however, unclear, how shorter ET periods may affect endothelial, systolic and diastolic ventricular function as echocardiographic parameters related to ventricular arterial coupling in patients with CHF. METHODS: In this ongoing study we randomised 43 patients with stable CHF (age 60.3 ± 2.9 years, EF 27.4 ± 1.7%, VO 2 max 14.7 ± 4.3ml/kg*min) to a training or a control group (C). Patients in the training group exercised 4 times daily at 70% of the individual heart rate reserve for 4 weeks under supervision. At baseline and after 4 weeks the E/A ratio and septal/lateral E’/A’ velocities were determined by echocardiography with tissue Doppler. Exercise capacity was measured by ergospirometry and flow-mediated dilatation (FMD) was assessed by high-resolution radial ultrasound. RESULTS: After only 4 weeks of ET oxygen uptake at peak exercise increased from 14.9 ± 3.3 to 18.1 ± 4.7 ml/min/kg, (p<0.01 vs. C) in training subjects. Left ventricular ejection fraction improved from 26.8 ± 4.6 to 33.1 ± 5.5% (p<0.05 vs. C) in patients of the training group while it remained unchanged in the control group. E/A-ratio mended from 0.63 ± 0.12 to 0.81 ± 0.22 (p<0.01 vs. C) in training patients. Septal E’ velocities increased from 5.5 ± 0.5 to 7.8 ± 1.4 cm/s in training patients (p<0.05 vs. C). FMD of the radial artery improved from 8.2 ± 2.1 to 15.2 ± 3.8% (p<0.01 vs. C) as a result of ET. CONCLUSIONS: Only 4 weeks of endurance training are highly effective with significantly improved FMD accompanied by an emended systolic and diastolic LV-function. We hypothesise that the improvement in LV-EF in training patients may be caused by a corrected ventricular-arterial coupling: ventricular diastolic relaxation and effective endothelial function are ameliorated resulting in an augmentation of stroke volume.

Background: One of uremic toxins, indoxyl sulfate (IS) is related to the progression of chronic kidney disease (CKD) and the worse cardiovascular outcomes. We have previously reported the relationship between IS levels and the severity of chronic heart failure (CHF), but the question arises as to whether the treatment of uremic toxin is beneficial in patients with CHF. This study aimed to elucidate whether the treatment with the oral adsorbent which reduces uremic toxin improved the cardiac function of the patients with CHF. Methods: First of all, we retrospectively enrolled 49 patients with both CHF and stage ≤3 CKD in our institute compared with the healthy subjects without CHF or CKD in the resident cohort study of Arita. Secondly, we retrospectively enrolled 16 CHF outpatients with stage 3-5 CKD. They were treated with and without the oral adsorbent of AST-120 for one year termed as the treatment and control groups, respectively. We underwent both blood test and echocardiography before and after the treatment. Results: First of all, among 49 patients in CHF patients, plasma IS levels increased to 1.38 ± 0.84 μg/ml from the value of 0.08 ± 0.06 μg/ml in Arita-cho as a community-living matched with gender and eGFR of CHF patients. We found both fractional shortening (FS) and E/e’, an index of diastolic function were decreased (25.0 ± 12.7%) and increased (13.7 ± 7.5), respectively in CHF patients compared with the value of FS and E/e’ in Arita-cho (FS: 41.8 ± 8.3%, E/e’: 8.8 ± 2.1). Secondly, in the treatment group, the plasma IS levels and the serum creatinine and brain natriuretic peptide levels decreased (1.40 ± 0.17 to 0.92 ± 0.15 μg/ml; p<0.05, 1.91 ± 0.16 to 1.67 ± 0.12 mg/dl; p<0.05, 352 ± 57 to 244 ± 49 pg/ml; p<0.05, respectively) and both FS and E/e’ were improved following the treatment with AST-120 (28.8 ± 2.8 to 32.9 ± 2.6%; p<0.05, 18.0 ± 2.0 to 11.8 ± 1.0; p<0.05). However, these parameters did not change in the control group. Conclusions: The treatment to decrease the blood levels of uremic toxins improved not only renal dysfunction but cardiac systolic and diastolic dysfunction in patients with chronic heart failure. Oral adsorbents might be a new treatment of heart failure especially with diastolic dysfunction.
