© 2020 Purpose: to study the effect of immunosupressive therapy (IST) in the virus-negative and virus-positive patients with immune-mediated myocarditis. Methods: in 60 patients (45 male, 46.7 ± 11.8 years, mean LV EDD, 6.7 ± 0.7 cm, EF 26.2 ± 9.1%) active/borderline myocarditis was verified by endomyocardial biopsy (n = 38), intraoperative biopsy (n = 10), examination of explanted heart (n = 3) and autopsy (n = 9). Indications for IST determined based on histological, immune activity. The follow-up was 19.0 [7.25; 40.25] months. Results: The viral genome in the myocardium was detected in 32 patients (V+ group), incl. parvovirus B19 in 23. The anti-heart antibody level was equally high in the V+ and V- patients. Antiviral therapy was administered in 24 patients. IST (in 22 V+ and 24 V- patients) include steroids (n = 40), hydroxychloroquine (n = 20), azathioprine (n = 21). The significant decrease of LV EDD (6.7 ± 0.7 to 6.4 ± 0.8), PAP (48.9 ± 15.5 to 39.4 ± 11.5 mm Hg, р<0,01), increase of EF (26.5 ± 0.9 to 36.0 ± 10.8), and lower lethality (23.9% and 64.3%; RR 0.37, 95% CI 0.19–0.71), p<0.01, were found only in IST group. Significant improvement due to IST were achieved not only in V-, but also in V+ patients. Conclusions: IST in patients with immune-mediated lymphocytic myocarditis is effective and is associated with lower lethality both in virus-negative and virus-positive patients.

© 2019, The Author(s). Background: Sudden cardiac death (SCD) refers to unanticipated death as a consequence of cardiac failure which takes place over a brief time period (typically within an hour of the commencement of symptoms) in an individual, who may or may not be known to be subject to cardiac disease, but in whom no fatal condition has been diagnosed. The objective of this investigation was to identify the potential cause of SCD in the young population in Moscow. Result: Analysis revealed that the mean age of the deceased amongst men was 24.6 years, and amongst women was 29.1 years. Seventy-six percent of sudden deaths were found to result from some previously undiagnosed pathology of the cardiovascular system, and cardiomyopathy is the most common cause of death in young people. Coronary heart disease is the most common cause of death in people above 40 years old. Conclusion: Investigation to diagnose the causes of SCD constitutes a relevant, comprehensive, and multidisciplinary undertaking, which ought to be founded upon the application of novel and current diagnostic methodologies. An integrated strategy to the quest for the underlying reason for sudden death ought to be founded upon the outcomes of biochemical, anatomical, genetic, pathophysiological, and other investigations. The search and development of objective risk factors will permit timely therapeutic intervention for patients with cardiovascular pathology to minimise and prevent the risk of sudden cardiac death.

© 2019 Elsevier B.V. Objective: Early pregnancy models for prediction of GDM have been proposed, mostly using anamnestic and biochemical parameters. The aim of our study was to evaluate the strength of association of first trimester fetal heart rate (FHR) in predicting the development of gestational diabetes (GDM). Study design: We considered in our analysis singleton non-diabetic pregnant women who underwent a first trimester screening at 11–14 weeks. Data on maternal age, BMI, cigarette smoking, NT, FHR, CRL, DV-PVI, β-hCG and PAPP-A were included in the analysis. Multivariate logistic regression analysis was used to estimate the association between maternal characteristics and first-trimester ultrasound measurements and GDM. We evaluated the efficacy of different models for the prediction of GDM. Results: We considered 603 women, of whom 199 (33%) were subsequently diagnosed with GDM. ROC analysis showed that first trimester FHR was highly predictive of GDM (AUC 0.809, 95% CI 0.769–0.849, p < 0.001). At FPR of 20%, first trimester FHR had a detection rate of 65.2% for GDM (positive likelihood ratio: 3.26; negative likelihood ratio: 0.43), which increased to 89.5% at FPR of 40% (positive likelihood ratio: 2.24; negative likelihood ratio: 0.17). When considering as threshold 162 bpm, FHR showed detection rate of 76.9%, specificity of 67.1% and negative predictive value of 85.5% for GDM. Conclusion: This is the first study to highlight the potential role of first trimester FHR as early predictor of GDM. In our cohort, a threshold of 162 bpm has shown high detection rate and NPV for GDM.

© 2019 by the authors. Superior polymers represent a promising alternative to mechanical and biological materials commonly used for manufacturing artificial heart valves. The study is aimed at assessing poly(styrene-block-isobutylene-block-styrene) (SIBS) properties and comparing them with polytetrafluoroethylene (Gore-texTM, a reference sample). Surface topography of both materials was evaluated with scanning electron microscopy and atomic force microscopy. The mechanical properties were measured under uniaxial tension. The water contact angle was estimated to evaluate hydrophilicity/hydrophobicity of the study samples. Materials' hemocompatibility was evaluated using cell lines (Ea.hy 926), donor blood, and in vivo. SIBS possess a regular surface relief. It is hydrophobic and has lower strength as compared to Gore-texTM (3.51 MPa vs. 13.2/23.8 MPa). SIBS and Gore-texTM have similar hemocompatibility (hemolysis, adhesion, and platelet aggregation). The subcutaneous rat implantation reports that SIBS has a lower tendency towards calcification (0.39 mg/g) compared with Gore-texTM (1.29 mg/g). SIBS is a highly hemocompatible material with a promising potential for manufacturing heart valve leaflets, but its mechanical properties require further improvements. The possible options include the reinforcement with nanofillers and introductions of new chains in its structure.

© 2019, Springer Science+Business Media, LLC, part of Springer Nature. Diallyl trisulfide (DATS) is distinguished as the most potent polysulfide isolated from garlic. The aim of our study was to investigate effects of oral administration of DATS on healthy and diabetic rats, with special attention on heart function. Rats were randomly divided into four groups: CTRL (healthy rats), DATS (healthy rats treated with DATS), DM (diabetic rats), DM + DATS (diabetic rats treated with DATS). DATS (40 mg/kg of body weight) was administered every other day for 3 weeks, at the end of which rats underwent echocardiography, glycemic measurement and redox status assessment. Isolated rat hearts were subjected to 30 min global ischemia and 60 min reperfusion, after which heart tissue was counterstain with hematoxylin and eosin and cardiac Troponin T staining (cTnT), while expression of Bax, B cell lymphoma 2 (Bcl-2), caspase-3, caspase-9 and superoxide dismutase-2 were examined in the left ventricle. DATS treatment significantly reduced blood glucose levels of diabetic rats, and improved cardiac function recovery, diminished oxidation status, attenuated cardiac remodeling and inhibited myocardial apoptosis in healthy and diabetic rats. DATS treatment causes promising cardioprotective effects on ex vivo-induced ischemia/reperfusion (I/R) injury in diabetic and healthy rat heart probably mediated by inhibited myocardial apoptosis. Moreover, appropriate DATS consumption may provide potential co-therapy or prevention of hyperglycemia and various cardiac complications in rats with DM.

Heart failure is a complex syndrome whose phenotypic presentation and disease progression depends on a complex network of adaptive and maladaptive responses. One of these responses is the endothelial release of NRG (neuregulin)-1-a paracrine growth factor activating ErbB2 (erythroblastic leukemia viral oncogene homolog B2), ErbB3, and ErbB4 receptor tyrosine kinases on various targets cells. NRG-1 features a multitasking profile tuning regenerative, inflammatory, fibrotic, and metabolic processes. Here, we review the activities of NRG-1 on different cell types and organs and their implication for heart failure progression and its comorbidities. Although, in general, effects of NRG-1 in heart failure are compensatory and beneficial, translation into therapies remains unaccomplished both because of the complexity of the underlying pathways and because of the challenges in the development of therapeutics (proteins, peptides, small molecules, and RNA-based therapies) for tyrosine kinase receptors. Here, we give an overview of the complexity to be faced and how it may be tackled.

© 2019, The Author(s). Introduction: This study examined the dynamics of 24-h electrocardiogram (ECG) monitoring parameters (Holter monitoring) in patients with ischemic heart disease (IHD) before and after conservative or surgical treatment of patients with voiding and storage lower urinary tract symptoms (LTS) due to benign prostatic hyperplasia (BPH). Methods: A total of eighty-three 57 to 81-year-old (mean age 70.4 ± 5.75 years) patients with LUTS/BPH and accompanying IHD were examined and treated at the Institute of Urology and Human Reproductive Health and Clinic of Cardiology of Sechenov University. All patients received recommended cardiac therapy at least 6 months before inclusion in the study. Results: Our study demonstrated that there is correlation between voiding and storage LUTS/BPH and Holter-detected cardiac impairments in patients with IHD/BPH. These data make it possible to consider LUTS/BPH (voiding and storage) as a factor in the additional functional and psychological load on the activity of patients with ischemic heart disease. Improvement of voiding and storage LUTS due to BPH and objective parameters of urination (Qmax) in patients treated with alpha-1 adrenoceptor blocker tamsulosin correlated with improvement of 24-h ECG monitoring parameters (Holter monitoring) in 72% of patients. Improvement of 24-h ECG monitoring parameters (Holter monitoring) 1 month after transurethral resection of the prostate (TURP) in IHD/BPH patients and indications for surgical treatment was observed in 65.7%. Negative dynamics of the Holter-based ECG was not registered in patients who were operated on. Conclusion: Holter monitoring helps to identify groups of patients in whom urinary impairments caused by prostatic hyperplasia negatively affect the course of IHD. Restored urination (either conservatively or operatively) in patients with BPH in 72% of cases decreased the number of fits of angina, thus influencing favourably the course of IHD. Trial Registration: ClinicalTrials.gov Identifier: NCT03856242.

© 2019, Mary Ann Liebert, Inc., publishers 2019. The purpose of our work was to study late cardiac complications after treatment for Hodgkin's lymphoma (HL) in children and adolescents. Methods: Sixty-seven patients were examined in the long term (>5 years) after chemoradiotherapy for HL according to two different programs of treatment (groups I and II). Mean total doses of radiotherapy (RT) to the mediastinum were 37.2 and 28.9 Gy, respectively. The status of the heart was assessed at the mean age of 22.7 years with electrocardiography (ECG) and echocardiography (EchoCG). Mean terms of follow-up were 16.4 and 9.5 years for group I and group II, respectively. Results: Incidence of ECG changes was equal between the groups (88% and 90%). The prevalence of signs of valvular calcifications and fibrosis was 70.9% after mediastinal doses ≥30 Gy, and 16.6% after lower doses (p = 0.002). Those changes led to considerable valvular dysfunction in four patients. EchoCG signs of pulmonary hypertension were seen in 33.3% patients of group I versus 4.8% in group II (p = 0.047). Pericardial effusion was observed in 7.4% and 5.1%, respectively (p = 1.0). Left ventricular ejection fraction decreased slightly only in two patients (one in each group). Conclusions: The RT mediastinal dose level is the important risk factor of late heart complications. Nevertheless, the differences in the rate and severity of those complications between the groups should be viewed with caution because of differences in the age at baseline and in follow-up terms. The survivors of HL should undergo life-long regular examinations of the heart status.

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. The aim of present study was to evaluate the effects of 3- and 6-week swimming exercise on cardiodynamics and coronary flow in high salt-induced hypertensive and normotensive rats. 80 male Wistar albino rats (6 weeks old) were divided into 8 groups: hypertensive animals that swam for 3 weeks; hypertensive animals that swam for 6 weeks and their respective sedentary controls; normotensive animals that swam for 3 weeks; normotensive animals that swam for 6 weeks and their respective sedentary controls. Hypertensive animals were on high sodium (8% NaCl solution) diet for 4 weeks, and these animals did not drink tap water during the experimental protocol. After sacrificing, hearts were isolated and perfused according to Langendorff technique at gradually increased coronary perfusion pressure (40–120 cmH2O). The following parameters of cardiac function were continuously recorded: maximum and minimum rate of pressure development in LV, systolic, and diastolic left ventricular pressure, and heart rate. Coronary flow was measured flowmetrically. Findings of the present study may help in better understanding of short- to medium-term exercise-induced direct effects on cardiac function and perfusion. Generally viewed, swimming of both durations did not change myocardial function and perfusion in hypertensive and normotensive conditions.

© 2017 Elsevier B.V. Background: Hospitalization is an opportunity to optimize heart failure (HF) therapy. As optimal treatment for hospitalized HF patients in sinus rhythm with heart rate ≥ 70 bpm is unclear, we investigated the impact of combined beta-blocker (BB) and ivabradine versus BBs alone on short and longer term mortality and rehospitalization. Methods and results: A retrospective analysis was performed on 370 hospitalized HF patients with heart rate ≥ 70 bpm (150 BB + ivabradine, 220 BB alone) in the Optimize Heart Failure Care Program in Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Russia, Ukraine, and Uzbekistan, from October 2015 to April 2016. Results: At 1 month, 3 months, 6 months and 12 months, there were fewer deaths, HF hospitalizations and overall hospitalizations in patients on BB + ivabradine vs BBs alone. At 12 months, all-cause mortality or HF hospitalization was significantly lower with BB + ivabradine than BBs (adjusted hazard ratio [HR] 0.45 (95% confidence interval [CI] 0.32–0.64, P < 0.0001). Significantly greater improvement was seen in quality of life (QOL) from admission to 12 months with BB + ivabradine vs BBs alone (P = 0.0001). With BB + ivabradine, significantly more patients achieved ≥ 50% target doses of BBs at 12 months than on admission (82.0% vs 66.6%, P = 0.0001), but the effect was non-significant with BBs alone. Conclusions: Heart rate lowering therapy with BB + ivabradine started in hospitalized HF patients (heart rate ≥ 70 bpm) is associated with reduced overall mortality and re-hospitalization over the subsequent 12 months. A prospective randomized trial is needed to confirm the advantages of this strategy.

© 2018 The Author(s) Published by S. Karger AG, Basel. Background: The most common functional gastrointestinal disorders (FGID) are functional dyspepsia (FD) and irritable bowel syndrome (IBS), with a prevalence in the general population of 15-20% (FD) and 10% (IBS), respectively. The complexity of pathophysiologic mechanisms and limitations in therapeutic options make the management of FD and IBS patients a challenge in routine clinical practice. Summary: Syndromes classified as FGID frequently overlap, and coexist with gastroesophageal reflux disease (GERD). Patients with overlapping symptoms are more likely to seek medical care. The challenge for routine clinical practice is to find the best approach for treatment of multiple symptoms. STW 5, a combination of 9 herbal extracts, was shown to have multi-target effects: it normalizes the disturbed gastrointestinal motility, alleviates hypersensitivity, inhibits inflammation, suppresses gastric hypersecretion, and modulates the microbiota. Controlled randomized studies proved STW 5 to be efficacious both in FD and IBS, with control over the full spectrum of upper and lower gastrointestinal symptoms. STW 5 reduced concomitant heartburn in FD patients. STW 5 was well tolerated in the examined populations, independent of concomitant diseases and concomitant medication. Key Messages: The clinical use of the herbal preparation STW 5 in FD and IBS is evidence-based. STW 5 is an example for the concept of multi-target therapy. It offers treatment opportunities in routine clinical practice with high prevalence of overlap of FGID and concomitant GERD. Considering that FD and IBS are typically chronic and recurrent conditions, the clinically observed good tolerability and safety of STW 5 is an advantage.

© 2017, Springer Science+Business Media, LLC. Drug-induced oxidative stress can occur in numerous tissues and organ systems (liver, kidney, ear, nervous system, and cardiovascular system). Cancer therapy with cisplatin is associated with side effects to which oxidative stress may contribute. We have compared the influences of cisplatin (reference compound) and its’ analogues (dichloro(1,2-diaminocyclohexane)platinum(II) and chloro(2,2′:6′,2″-terpyridine)platinum(II)) in a model of isolated rat heart using the Langendorff technique. The production of oxidative stress biomarkers, antioxidant enzymes, myocardial damage, and expression of Bax, OH-1, and SODs were studied. Cisplatin and the analogues were perfused at concentration of 10−6 and 10−5 M during 30 min. The results of this study showed that examined platinum complexes had different ability to induce oxidative stress of isolated perfused rat heart. Varying the carrier ligands, such as 1,2-diaminocyclohexane and 2,2′:6′,2″-terpyridine, related to amino ligands (cisplatin) directly influenced the strength to induce production of oxidative stress biomarkers. Introducing 2,2′:6′,2″-terpyridine ligands provoked the smallest changes in antioxidant enzymes activity, lipid peroxidation, and expression of heme oxygenase-1, that undoubtedly indicated that this complex had the lowest impact on redox status in heart tissue. These findings may be useful in synthesis of novel platinum analogues with lower potential for oxidative stress induction. However, the fact that platinum complexes could induce toxic effects in the heart by other mechanisms should be taken into the consideration.

In the clinical practice a physician quite often is at a loss due to “freedom of choice” granted by availability of direct oral anticoagulants (DOAC). If a patient with nonvalvular atrial fibrillation (AF) has indications for therapy with anticoagulants which DOAC should be preferred? What are benefits for a patient with ischemic heart disease and AF when definite NOAC is chosen and what are risks inherent of this choice? Answers to such questions are given in this paper.

© 2018 Limited Liability Company KlinMed Consulting. All Rights Reserved. Background: Literature data on hepcidin (H) level - the main regulator of systemic iron homeostasis in patients with chronic heart failure (CHF) - are contradictory. Relationships of H with markers of inflammation elevated level of which is characteristic of CHF are insufficiently studied. The latter problem remains practically unexplored in elderly and very old patients with CHF. Aim: to study the role of H in formation of anemia of chronic disease (ACD) and iron deficiency anemia (IDA) in elderly and very old patients with CHF. Material and methods: We examined 65 elderly and very old patients with ischemic heart disease (IHD) (35 with CHF and ACD, 10 with CHF and IDA, 20 without CHF, ACD, and IDA [control group]). H level in blood serum was measured using competitive solid-phase immunoenzyme assay. Results and discussion: In patients with CHF and ACD mean H levels were significantly high relative to those in patients with CHF and IDA, while in the latter group H levels were insignificantly low relative to those in patients of control group. High H level, high level of inflammatory tests as well as positive correlations between them, and negative correlation between H and hemoglobin (Hb) are indicative of inflammation as a cause of H level elevation, which in turn facilitates development of anemia in elderly and very old patients with CHF and ACD. Low H level, normal levels of inflammatory tests, absence of links between them, as well as absence of correlation between H and Hb are indicative of lack of H role in development of anemia in these patients with CHF and IDA. We did not study influence on development of anemia of each of possible causes (inflammation, decompensation of CHF) separately, therefore contribution of each of them is unknown. The data obtained also do not exclude effect of other not investigated in this work and presently unknown factors. Received by us data indicate to necessity of precise identification of origin of anemia in every case in an elderly or very old patient with CHF with the aim of elimination of its cause and conduct of pathogenetically valid therapy.

© 2018 EBSCO Information Services. Background. Reported levels of hepcidin, the major regulator of systemic iron homeostasis in CHF patients, are controversial. Relationship of hepcidin with inflammation markers, which are typically increased in CHF, is understudied; this issue is practically unstudied in old and older CHF patients. Aim. To study the role of hepcidin in development of anemia of chronic disease (ACD) and the association of hepcidin with inflammation in old and older CHF patients. Materials and methods. Ninety old and older patients with IHD were evaluated. 35 of these patients had CHF and ACD and 35 patients had CHF without ACD. The control group (CG) consisted of 20 IHD patients without CHF and ACD. Serum concentration of hepcidin was measured using ELISA by the competitive binding principle. Results. Patients with severe, congestive FC IV CHF prevailed among CHF patients with ACD, and their CHF was characterized with longer duration, more frequent hospitalizations, and lower compliance with the treatment. Significantly higher mean levels of hepcidin, C-reactive protein (CRP), erythrocyte sedimentation rate, and insignificantly higher levels of ferritin were observed in CHF patients with than without ACD. The high hepcidin, indexes of inflammation tests, and a significant positive correlation of hepcidin with hemoglobin levels suggested inflammation as a cause for the increased hepcidin, which induced anemia in old and older CHF patients with ACD.

© 2018 Media Sphera Publishing Group. All rights reserved. Aim. To perform a comparative analysis of anemia of chronic disease (ACD) and iron-deficiency anemia (IDA) in late middle-aged and elderly patients with chronic heart failure (CHF) by ferrokinetic parameters, inflammation indexes, and their associations. Materials and methods. 65 patients with ischemic heart disease were evaluated, including 35 patients with CHF and ACD, 10 patients with CHF and IDA, and 20 patients without CHF, ACD, and IDA (control group, CG). Results. Patients with CHF and IDA had true iron deficiency whereas 54% of patients with CHF and ACD had functional iron deficiency, and 46% of patients had no iron deficiency. Levels of acute phase proteins, ferritin and hepcidin, C-reactive protein (CRP), and interIeukin-6 (IL-6) were highly sig-nificantly different in patients with CHF and ACD and patients with CHF and IDA; positive and significant correlations were found for levels of IL-6 and ferritin, IL-6 and CRP, and CRP and hepcidin. In patients with CHF and IDA, levels of acute phase proteins, ferritin and hepcidin, CRP, and IL-6 were low and correlations of IL-6 with ferritin, IL-6 with CRP, and CRP with hepcidin were non-significant. Concentrations of erythropoietin were significantly higher in patients with CHF and ACD and patients with CHF and IDA compared to the control group; however, significant differences between them were absent.

The structure of the atherosclerotic plaque plays an important role in the development of the mechanism of intracoronary thrombosis. Currently, there are various radiological methods for diagnosis of atherosclerotic plaques of the coronary arteries. The current review reveals the theme of "indirect" signs of instability of atherosclerotic plaques, their combinations and occurrence, detected by computed tomography. Retrospective studies have shown the feasibility of these signs of plaques in the assessment of the prognosis of acute coronary events. The review compares the results of computed tomography (CT) and intravascular ultrasound, which is the gold standard in the diagnosis of atherosclerotic plaque morphology.

The article discusses various mechanisms of developmentt and progression of arterial hypertension in young and middle aged adults. It emphasizes the predominant role of hypersympathicotonia in the development of the disease in this category of patients. Various mechanisms are considered, by means of which the increase of activity of the sympathetic nervous system leads to elevation of arterial pressure and potentiates early damage of target organs, first of all, damage of the heart. The data of numerous studies demonstrating pronounced cardioprotective effects of a highly selective representative of the class of β-blockers bisoprolol in young and middle aged hypertensive patients are presented.

Purpose: to assess prevalence of dyslipidemia in patients with ischemic heart disease (IHD) older than 75 years as well as to evaluate possible associations between serum lipids and various cardiovascular and other diseases in these patients. Methods: We enrolled in this cross sectional study 555 hospitalized IHD patients aged 75-98 years (mean age 86.8 years, 74.5% women). Levels of lipids (total cholesterol [TC], triglycerides [TG], low and high-density lipoprotein cholesterol [LDLC, HDLC]) were measured by enzyme method on the biochemistry analyzer Konelab 60i. Results: Elevated TC; hypertriglyceridemia and elevated LDLC were observed in 13.3, 10.4 and 26.3% of patients, respectively. In the majority of patients severity of dyslipidemia was mild. With increasing age serum levels of TC and LDLC decreased. Negative correlation between TC level and patient's age was significant (r= -0.13; p=0.001). Mean TC level was 5.43, 5.0 and 4.7 mmol/l in patients aged <80 (group 1), 80-89 (group 2), and ≥90 (group 3) years, respectively (p=0.001 for differences between groups 1-and 3). Similar results were registered in respect of LDLC: mean LDLC level was 3.7 and 2.7 mmol/l in groups 1 and 3, respectively (p=0.004). Mean concentrations of all lipids in women were higher than in men: TC 5.1 vs 4.5 (p<0.0001), LDLC 3.1 vs 2.5 (p=0.0002), HDLC - 1.26 vs 1.17 mmol/l (p=0.01). Lower lipids levels (especially those of TC) were significantly associated with clinically significant heart failure (p<0.0001) and atrial fibrillation (p<0.0001). Higher TC and TG correlated positively with higher systolic and diastolic blood pressure (p=0.001). Significant positive correlations existed between TG and glucose concentration (p<0.0001) as well as between TG and uric acid level (p=0.001). Higher TG and lower HDLC levels were registered in patients with higher creatinine level (p=0.001 and 0.0003, respectively). Only 11.4% of study patients received statins. Conclusion: The study results evidence for considerable peculiarities of lipid profile in the very elderly patients with IHD. Significant associations between dyslipidemia and a number of diseases were also revealed.
