Objectives: to determine the causes of ineffective observation and poor prognosis in patients undergoing ADHF, in real clinical practice and to consider the basics of the formation of specialized medical care for patients with heart failure (HF).Materials and methods: the study was conducted based on the City Center for the treatment of heart failure (center HF), N. Novgorod. The study consistently included 942 patients with heart failure (HF) at the age of 18 years and older who underwent ADHF and received inpatient treatment in center HF between March 4, 2016 and March 3, 2017. Based on the decisions of patients to continue outpatient monitoring in center HF, two groups of patients were distinguished: patients who continued to be monitored in center HF (group I, n = 510) and patients who continued to be monitored in outpatient clinics at the place of residence (group II, n = 432). The assessment of adherence to treatment, overall mortality, survival and re-admission to a depth of two years of observation was carried out. Statistical data processing was performed using Statistica 7.0 for Windows and the software package R.Results: all patients in the study groups had high comorbidity. Group 2 patients turned out to be statistically significantly older, more often had III functional class (FC) HF, lower the baseline test score of 6-minute walk, and higher the baseline clinical assessment scale. After 2 years of follow-up in group II, there was a significant deterioration in adherence to basic therapy of HF compared with group I. According to the results of multifactorial proportional risk Cox models, it was shown that observation of patients in the group 1 is an independent factor increasing the risk of overall mortality by 2.8 times by the end of the second year of observation. Survival after two years of follow-up was: in group I — 89.8 %, and in group II — 70.1 % of patients (OR = 0.3, 95 % CI 0.2 – 0.4; p1/2 < 0.001). After two years of follow-up, the proportion of re-hospitalized patients in group II was greater (78.0 % of patients) versus group 1 (50.6 % of patients, OR = 3.5, 95 % CI 2.6 – 4.6; p1/2 <0.001). The independent risk of re-hospitalization according to multinominal logit regression was 3.4 times higher in group II and 2.4 times for III – IV FC HF. Conclusions: the inclusion of patients with HF in the system of specialized medical care improves adherence to treatment, prognosis of life and reduces the risk of repeated hospitalizations. Patients of an older age and with an initially greater clinical severity refused specialized supervision in center HF.

Impact of tissue lactate accumulation on prognosis after acute myocardial infarction (AMI) is biased. The study aimed to assess the prognostic role of lactate concentration (LC) in patients with AMI during one year of follow-up. 145 consecutive patients admitted due to AMI were enrolled. The data on the frequency of endpoint occurrence (defined as I, death; II, heart failure (HF); and III, recurrent myocardial infarction (re-MI)) were collected. The patients were divided into group A (LC below the cut-off value) and group B (LC above the cut-off value) for the endpoints according to receiver operating characteristic (ROC) analysis. The cumulative survival rate was 99% in group I-A and 85% in group I-B (p = 0.0004, log-rank test). The HF-free survival rate was 95% in group II-A and 82% in group II-B (p = 0.0095, log-rank test). The re-MI-free survival rate did not differ between groups. A multivariate Cox analysis showed a statistically significant influence of LC on death [Hazard Ratio (HR): 1.41, 95% Confidence Interval (CI) (1.13–1.76), and p = 0.002] and HF [HR: 1.21, 95% CI (1.05–1.4), and p = 0.007] with no impact on re-MI occurrence. LC in capillary blood may be considered a useful prognostic marker of late-onset heart failure and death after AMI.

Abstract Funding Acknowledgements Type of funding sources: None. Nowadays the term "heart-vessels failure" does not exist. Aim. To study the kinetics and hemodynamics of arteries in the patients with heart failure with different ejection fraction. Materials and methods. In our investigation we included 74 patients with heart failure with preserved ejection fraction more than 55% (44 were men and 30 women). Mediana age – 71,3 years old. In the control group we included 52 practically healthy people without cardiac and vessels pathologies.  We divided patients into two groups (I and II) in accordance to the presence of clinical manifestations of heart failure in them. Group I - with clinical symptoms of heart failure (32), group II –without heart failure symptoms (42).  We paid attention to the symptoms of  heart failure, myocardial infarction, cardiomyopathies, valves defects, operations on heart in anamnesis. We performed 24-hours ECG monitoring, general blood analysis, biochemical blood analysis (lipids, electrolytes, urine, creatinine, bilirubin, potassium, glucose, NT-proBNP),  transthoracic echocardiography, ultrasound doppler of brachiocephalic arteries, abdominal aorta branches, lower extremities arteries, renal arteries, chest radiography, ultrasound investigation of B-lines. If prescribed we performed stress echocardiography, transesophageal echocardiography, coronary angiography, renal arteries angiography, pancerebral angiography, magnet tomography of heart. All patients were registered sphygmography of main arteries: a.carotis communis, ulnaris, radialis, a.tibialis posterior. We analyzed the regular contractions in each type of arteries. The main parameters main arteries kinetics using sphygmography we calculated in automatic mode: speed, acceleration, power, work in period of prevalence of inflow over outflow and in period of  prevalence of outflow over inflow.  Results. We analysed the main parameters of arteries kinetics and hemodynamics in each group of patients as well as in control group. We observed the effects: 1)In group II the parameters of arteries kinetics were higher than in group I. It indicates the active propulsive work of arteries in spreading the stroke volume of the heart. 2)In group I the parameters of arteries kinetics were lower than in control group. It indicates that propulsive function of the arteries is reduced in patients with heart failure. Conclusion. Arterial vessels are active, full-fledged participant in cardiovascular system. Vessels make an active work in blood movement from the heart to the distal parts and tissues. The clinical manifestations of heart failure are determined not only the heart function but also the function of arteries that is needed to be examined. In patients with preserved ejection fraction we can observe the symptoms of heart failure, the function abilities of arteries are reduced. The term "heart-vessels failure" should be used and applied not only to the heart but also to the arteries function in their coupling with heart. Abstract Figure.

Aim: to study the association between ST2 (sST2) and severity of coronary artery lesion in patients with chronic heart failure (CHF), and to analyze changes in sST2 levels and left ventricle (LV) remodeling indicators depending on complete or incomplete myocardial revascularization (MR) after the 12-month follow-up period.Patients and Methods: a total of 118 patients (16.1% women, mean age of 62.5 [57; 68] years) with stable coronary heart disease (CHD) with LV ejection fraction 60% [46; 64] and CHF of NYHA functional class I–III were enrolled in the study. All patients underwent MR. Depending on the completeness of the performed MR, all patients were retrospectively divided into 2 groups: group 1 (n=75) consisted of patients with complete MR, group 2 (n=43) — with incomplete MR. Serum levels of sST2 were measured using an enzyme immunoassay before MR and after the 12-month follow-up period.Results: the sST2 level in patients with single vessel coronary artery disease was 29.92 [22.43; 32.68] ng/ml and was 21% lower (p=0.002) than in patients with two or more coronary arteries (CA) — 37.87 [37.87; 51.82] ng/ml. During 12-month follow-up, the incidence of adverse cardiovascular events (CVE) in group 1 was 18.7%, in group 2–46.5% (p=0.001). After 12-month follow-up, the level of sST2 in group 1 decreased by 33.6% (p=0.0001) (from 30.51 [26.38; 37.06] to 20.27 [16.56; 27.11] ng/ml), while in group 2 there was only a tendency to decrease in the level of this biomarker, which was 6.9%. In group 2, after 12-month follow-up, there was a tendency to increase in the LV EF, which increased by only 2.4%, as well as a tendency to increase in the end-systolic dimension (ESD), which increased by 5.4%. In the group of patients with complete MR, the increase in the LV EF was significant (p=0.001) — by 13.6% (from 54.0 [42.0; 63.0] to 62.5 [49.0; 64.0]%), and the ESD decreased by 3%, the final ESV — by 4.6%.Conclusion: the sST2 level can be used as a diagnostic marker for assessing the severity of atherosclerotic CA lesion in patients with CHF. Performing complete MR in patients with stable CHD with CHF has a predominance over incomplete MR, leading to reversed LV remodeling, a decrease in sST2 levels and, as a result, the incidence of adverse CVE during the 12-month follow-up.

Background Mortality from chronic heart failure (CHF) remains high and entails serious demographic losses worldwide. The most vulnerable group is patients after acute decompensated HF (ADHF) who have a high risk of unfavorable outcome.Aim To analyze risks of all-cause death (ACD), cardiovascular death (CVD), and death from recurrent ADHF in CHF patients during two years following ADHF in long-term follow-up with specialized medical care and in real-life clinical practice.Material and methods The study successively included 942 CHF patients after ADHF. 510 patients continued out-patient treatment in a specialized CHF treatment center (CHFTC) (group 1) and 432 patients refused of the management in the CHFTC and were managed in out-patient clinics at the place of patient’s residence (group 2). Causes of death were determined based on inpatient hospital records, postmortem reports, or outpatient medical records. Cases of ACD, CVD, death from ADHF, and a composite index (CVD and death from ADHF) were analyzed. Statistical analysis was performed with the software package Statistica 7.0 for Windows, SPSS, and statistical package R.Results Patients of group 2 were older, more frequently had functional class (FC) III CHF and less frequently FC I CHF compared to group 1. Women and patients with preserved left ventricular ejection fraction (LV EF) prevailed in both groups. Results of the Cox proportional hazards model for ACD, CVD, death from ADHF, and the composite mortality index showed that belonging to group 2 was an independent predictor for increased risk of death (р<0.001). An increase in CCS score by 1 also increased the risk of death (р<0.001). Baseline CHF FC and LV EF did not influence the mortality in any model. Female gender and a higher value of 6-min walk test (6MW) independently decreased the risk of all outcomes except for CVD. An increase in systolic BP by 10 mm Hg reduced risk of all fatal outcomes. At two years of follow-up in groups 2 and 1, ACD was 29.9 % and 10.2 %, (OR, 3.7; 95 % CI: 2.6–5.3; p <0.001), CVD was 10.4 % and 1.9 % (OR, 5.9; 95 % CI: 2.8–12.4; p<0.001), death from ADHF was 18.1 % and 6.0 % (OR, 3.5; 95 % CI: 2.2–5.5; p<0.001), and the composite mortality index was 25.2 % and 7.7 % (OR, 4.1; 95 % CI: 2.7–6.1; р<0.001). Analysis of all outcomes by follow-up period (3 and 6 months and 1 and 2 years) showed that the difference between groups 2 and 1 in risks of any fatal outcome was maximal during the first 6 months.Conclusion The follow-up in the system of specialized medical care reduces risks of ACD, CVD, and death from ADHF. The first 6 months following discharge from the hospital was a vulnerability period for patients after ADHF. The CCS score impaired the prognosis whereas baseline LV EF and CHF FC did not influence the long-term prognosis after ADHF. Protective factors included female gender and higher values of 6MW and systolic BP.

Recent European Society of Cardiology and American Heart Association/American College of Cardiology Guidelines did not recommend biomarker-guided therapy in the management of heart failure (HF) patients. Combination of echo- and B-type natriuretic peptide (BNP) may be an alternative approach in guiding ambulatory HF management. Our aim was to determine whether a therapy guided by echo markers of left ventricular filling pressure (LVFP), lung ultrasound (LUS) assessment of B-lines, and BNP improves outcomes of HF patients. Consecutive outpatients with LV ejection fraction (EF) ≤ 50% have been prospectively enrolled. In Group I (n=224), follow-up was guided by echo and BNP with the goal of achieving E-wave deceleration time (EDT) ≥ 150 ms, tissue Doppler index E/e′ < 13, B-line numbers < 15, and BNP ≤ 125 pg/ml or decrease >30%; in Group II (n=293), follow-up was clinically guided, while the remaining 277 patients (Group III) did not receive any dedicated follow-up. At 60 months, survival was 88% in Group I compared to 75% in Group II and 54% in Group III (χ2 53.5; p<0.0001). Survival curves exhibited statistically significant differences using Mantel–Cox analysis. The number needed to treat to spare one death was 7.9 (Group I versus Group II) and 3.8 (Group I versus Group III). At multivariate Cox regression analyses, major predictors of all-cause mortality were follow-up E/e′ (HR: 1.05; p=0.0038) and BNP >125 pg/ml or decrease ≤30% (HR: 4.90; p=0.0054), while BNP > 125 pg/ml or decrease ≤30% and B-line numbers ≥15 were associated with the combined end point of death and HF hospitalization. Evidence-based HF treatment guided by serum biomarkers and ultrasound with the goal of reducing elevated BNP and LVFP, and resolving pulmonary congestion was associated with better clinical outcomes and can be valuable in guiding ambulatory HF management.

Recurrent Nephrolithiasis

Introduction. Chronic kidney disease (CKD) is commonly diagnosed in patients with cardiovascular diseases (CVDs) and also manifests itself in most patients with urolithiasis. Numerous studies have shown that renal dysfunction is not only directly related to the high risk of developing various CVDs and chronic heart failure (CHF) as one of the most common complications but also the mortality rate in comorbid patients. CKD and CHF have similar pathogenetic mechanisms and common target organs; co-existing, both pathological conditions accelerate the progression of major diseases and significantly aggravate their course. In patients with recurrent nephrolithiasis combined with CVDs, all the causes leading to the formation of CKD (recurrent obstructive pyelonephritis, nephroangiosclerosis, etc.) are present to some extent.Purpose of the study. To evaluate the incidence and characteristics of CKD in patients suffering from recurrent urolithiasis associated with CVDs.Materials and methods. The prospective study included 406 patients who were treated for recurrent nephrolithiasis and concomitant CVDs from 2007 to 2020 (Urology Division, Burdenko Principal Military Clinical Hospital). From long-term follow-up respondents who lived at least 10 years after inclusion in the study (n = 52), three groups were formed: group I (n = 18) included patients with a combination of essential hypertension (EH) and ischemic heart disease (IHD), complicated by CHF; group II (n = 15) consisted of patients with uncomplicated CVDs (EH – 7 patients, IHD – 8 patients). The control group III (n = 19) included respondents suffering from nephrolithiasis without CVDs. The glomerular filtration rate (GFR) was determined by the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) following the Russian National Guidelines for «Chronic Kidney Disease». The analysis of the obtained data was carried out using Statistica 8.0; the Fisher and Wilcoxon criteria were calculated; the differences were considered significant at p < 0.05.Results. All patients included in the study were repeatedly hospitalized urgently and as planned and underwent at least one non-invasive manipulation or surgery. The average age of the patients was 58.9 ± 2.95 years; men predominated (~ 75 – 78%). A GFR decrease was recorded in 41.1% of patients included in the study, in 40.5% of patients with a combination of nephrolithiasis and uncomplicated CVDs, Also, its decrease was found in 60 (58.8%) of patients with chronic heart failure (CHF) in 41.1% of cases from the general sample and 40.5% of patients without CHF. CKD stage II occurred in 44 (43.1%) cases of CHF; CKD stages III Ca and Cb were detected in 10 (9.8%) and 4 (1%) cases, respectively; CKD stage IV developed in 1 (0.25%) patient with one of the re-hospitalizations. Of the 52 patients included in the second study part, the ratio of men and women was 41/11 (78.8 and 21.2%, respectively). All three groups were also dominated by men. The initial values of GFR in group I patients significantly differed from those in the control group; in group II, statistically significant differences appeared 4 years after the s the study initiation, and in group I – after 2 years. A sharp (1.5-fold) significant decrease in renal filtration function was registered in group I by the 6th research year, in group II (1.3-fold) – by the 8th research year, and in group III (1.28-fold) – only by the 10th research year. The GFR level in group I and group II decreased during the 1st follow-up year by 2.36 and 1.65 times, respectively.Conclusion. CKD in patients suffering from recurrent nephrolithiasis in combination with IHD and EH is generally benign. The progression rate of filtration deficiency is relatively low and is (at least in the early stages) about 4.5 ml/min per year. The addition of CHF increases the rate of decline in renal filtration function by up to 25% (from 4 ml/min per year to 5 ml/min per year). The main negative effect of concomitant CVDs (especially complicated CHF) is not an ultrahigh decrease in GFR but a reduction in kidney functioning stable period up to complete cessation.

Objective: Comparison between bovine-derived demineralized bone matrix (DMBM) and iliac crest graft over long term for secondary alveolar bone grafting (SABG) in patients with unilateral cleft lip and palate (UCLP) in terms of radiological and clinical outcomes. Design: Prospective, randomized, parallel groups, double-blind, controlled trial. Setting: Unit of Oral and Maxillofacial Surgery, Oral Health Science Centre, Postgraduate Institute of Medical Education & Research, Chandigarh. Participants: Twenty patients with UCLP. Interventions: Patients were allocated into group I (Iliac crest bone graft) and group II (DMBM) for SABG. Outcomes were assessed at 2 weeks, 6 months, and then after mean follow-up period of 63 months. Outcomes Measures: Volumetric analysis of the grafted bone in the alveolar cleft site was done through cone beam computed tomography using Cavalieri principle and modified assessment tool. Clinical assessment was performed in terms of pain, swelling, duration of hospital stay, cost of surgery, alar base symmetry, and donor site morbidity associated with iliac crest harvesting. Results: Volumetric analysis through Cavalieri principle revealed comparable bone uptake at follow-up of 6 months between group I (70%) and group II (69%). Modified assessment tool showed no significant difference between horizontal and vertical bone scores over short- and long-term follow-up. In group II, there was higher cost of surgery, but no donor site morbidity unlike group I. Conclusions: Demineralized bone matrix proved analogous to iliac crest bone graft as per volumetric analysis over shorter period. However, although statistically insignificant, net bone volume achieved was lower than the iliac crest graft at longer follow-up.

Abstract Objective: The aim of this meta-analysis was to investigate the association between malnutrition assessed by the controlling nutritional status (CONUT) score and all-cause mortality in patients with heart failure. Design: Systematic review and meta-analysis. Settings: A comprehensively literature search of PubMed and Embase databases was performed until 30 November 2020. Studies reporting the utility of CONUT score in prediction of all-cause mortality among patients with heart failure were eligible. Patients with a CONUT score ≥2 are grouped as malnourished. Predictive values of the CONUT score were summarized by pooling the multivariable-adjusted risk ratios (RR) with 95 % CI for the malnourished v. normal nutritional status or per point CONUT score increase. Participants: Ten studies involving 5196 patients with heart failure. Results: Malnourished patients with heart failure conferred a higher risk of all-cause mortality (RR 1·92; 95 % CI 1·58, 2·34) compared with the normal nutritional status. Subgroup analysis showed the malnourished patients with heart failure had an increased risk of in-hospital mortality (RR 1·78; 95 % CI 1·29, 2·46) and follow-up mortality (RR 2·01; 95 % CI 1·58, 2·57). Moreover, per point increase in CONUT score significantly increased 16% risk of all-cause mortality during the follow-up. Conclusions: Malnutrition defined by the CONUT score is an independent predictor of all-cause mortality in patients with heart failure. Assessment of nutritional status using CONUT score would be helpful for improving risk stratification of heart failure.
