Abstract BACKGROUND New echocardiographic phenotypes of heart failure (HF) are focused on myocardial systolic involvement of the left ventricle (LV), either endocardial and/or transmural. PURPOSE. To study the pattern of myocardial involvement in patients (p) with HF with preserved left ventricular ejection fraction (pLVEF) and cardiac amyloidosis (CA). METHODS. Comparative study of 16 p with CA and HF with pLVEF, considering as cut point LVEF > 50%, in NYHA class ≥ II / IV, and a control group of 16 healthy people. Longitudinal Strain (LS) and Circumferential Strain (CS) were calculated using 2D speckle-tracking echocardiography, along with Mitral Annulus Plane Systolic Excursion (MAPSE) and Base-Apex distance (B-A). Also, the following indexes were calculated: Twist (apical rotation + basal rotation, º); Classic Torsion (TorC): (twist/B-A, º/cm); Torsion Index (Tor.I): (twist/MAPSE, º/cm) and Deformation Index (Def.I): (twist/LS, º). We suggest the introduction of these dynamic torsion indexes as Tor.I and Def.I that include twist per unit of longitudinal systolic shortening of the LV instead of using TorC which is the normalisation of twist to the end-diastolic longitudinal diameter of the LV. RESULTS There were no differences of age between the groups (68.2 ± 11.5 vs 63.7 ± 2.8 years, p = 0.14). Global values of LS and CS were lower in p with CA indicating endocardial and transmural deterioration during systole, while TorC and Twist of the LV remained conserved in p with CA. However, there is an increase of dynamic torsion parameters such as Tor.I and Def.I that show an increased Twist per unit of longitudinal shortening of the LV in the CA group (Table). CONCLUSIONS In p with CA and HF with pLVEF, the impairment of LS and CS indicates endocardial and transmural systolic dysfunction. In these conditions, LVEF would be preserved at the expense of a greater dynamic torsion of the LV.

Abstract Background Arterial stiffness is strongly linked to the pathogenesis of heart failure and the development of acute decompensation in patients with stable chronic heart failure. This study aimed to compare arterial stiffness indices in patients with heart failure with reduced ejection fraction (HFrEF) during the acute decompensated state, and three months later after hospital discharge during the compensated state. Results One hundred patients with acute decompensated HFrEF (NYHA class III and IV) and left ventricular ejection fraction ≤ 35% were included in the study. During the initial and follow-up visits, all patients underwent full medical history taking, clinical examination, transthoracic echocardiography, and non-invasive pulse wave analysis by the Mobil-O-Graph 24-h device for measurement of arterial stiffness. The mean age was 51.6 ± 6.1 years and 80% of the participants were males. There was a significant reduction of the central arterial stiffness indices in patients with HFrEF during the compensated state compared to the decompensated state. During the decompensated state, patients presented with NYHA FC IV (n = 64) showed higher AI (24.5 ± 10.0 vs. 16.8 ± 8.6, p < 0.001) and pulse wave velocity (9.2 ± 1.3 vs. 8.5 ± 1.2, p = 0.021) than patients with NYHA FC III, and despite the relatively smaller number of females, they showed higher stiffness indices than males. Conclusions Central arterial stiffness indices in patients with HFrEF were significantly lower in the compensated state than in the decompensated state. Patients with NYHA FC IV and female patients showed higher stiffness indices in their decompensated state of heart failure.

Abstract Background Cardiac amyloidosis (CA) is increasingly recognized as an underlying cause of heart failure with preserved ejection fraction (HFpEF), associated with high morbidity and mortality. However, most studies, solely investigated the prevalence of CA in special subgroups including HFpEF and severe aortic valve disease. Purpose With the present study we sought to investigate prevalence of different phenotypes of CA in an all comer-population of patients with non-ischaemic heart failure (HF) and to analyze the impact of CA on all-cause mortality. Methods The My Biopsy HF-Study (German clinical trials register number: 22178) is a retrospective monocentric study investigating the underlying etiology of HF in an all-comer population of patients with HF of unknown etiology. Patients presenting with symptoms of HF at the University Medical Centre between 14/10/2012 and 01/03/2021, who underwent endomyocardial biopsy (EMB) were enrolled in the present study. Ischaemic HF and valvular HF were ruled out prior to EMB. Specimens were sent for further examination to a specialized laboratory approved by the Food and Drug Administration Results Between October 2012 and March 2021, 767 patients (71.6% men) with HF of unknown etiology were included. Mean age at the time of presentation was 55.4 years (±14.4). Altogether, 72.5% of the patients presented with HF with reduced ejection fraction (HFrEF), 7.1% were diagnosed with HF with mid-range ejection fraction (HFmrEF) and 20.4% with HFpEF. Based on histological examination and genotyping, CA was diagnosed in 44 (5.7%) patients (immunglobulin light chain [AL] CA: 15 patients; variant transthyretin [ATTRv] CA: 6 patients; wild type transthyretin [ATTRwt] CA: 21 patients; de novo CA: 2 patients). Patients with CA were older compared with patients without CA (69.4±11.4 vs. 54.1±14.5; p&lt;0.0001), had a higher prevalence of arterial hypertension (68.2% vs. 50.9%; p=0.045) and showed a better left ventricular ejection fraction based on echocardiographic examination (47.5% vs. 32.6%; p&lt;0.0001). With respect to biomarker expression, levels of both brain natriuretic peptide and high-sensitive troponin I were significantly higher in patients without CA (BNP: 914.1 vs 612; p=0.01; troponin I: 812.8 vs. 171.7; p=0.006). In univariate logistic regression analysis CA was associated with a significant all-cause mortality (hazard ratio [HR] per unit increase [ui], 5.17, 95% CI, 2.93–9.08; p&lt;0.0001), even after adjustment for classical cardiovascular risk factors (HRperui 3.12, 95% CI, 1.11–8.76; p=0.03) and comorbidities like chronic obstructive pulmonary disease, chronic kidney disease and stroke (HRperui 2.93, 95% CI, 1.2–7.15; p=0.018). Conclusions Among patients presenting with HF of unknown etiology, including patients with HFpEF, HFmrEF and HFrEF, cardiac amyloidosis is the underlying cause of HF in 5.7% of patients and is independently associated with all-cause mortality.

Abstract Background Sacubitril/Valsartan has been shown to improve symptoms and outcomes in patients with heart failure (HF) reduced ejection fraction in a single large randomised controlled trial. However, real-world data on its effect is limited. Purpose Our centre operates a dedicated HF clinic for the initiation and titration of Sacubitril/Valsartan in suitable patients. We report on patient tolerability and incidence of adverse effects. We also assessed change in New York Heart Association (NYHA) class and left ventricular ejection fraction (LVEF) post-treatment, as well as HF hospitalisation and mortality at 6 months. Methods We conducted a retrospective review of all patients seen in the clinic between January 2016 to January 2019. Patient demographics and pre-initiation treatments were recorded. We compared NYHA class and LVEF category as measured by echocardiography, at initiation and post-titration to the maximum tolerated dose. Data on HF admissions were obtained from electronic hospital records and mortality from a national database. Results A total of 179 patients were initiated on Sacubitril/Valsartan and included in the study. Mean age was 71 years (41–90), and 138 (77%) were male. Half of the patient cohort (89) had an ischaemic aetiology. Prior to initiation, all patients were established on an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker. Almost all were on a beta-blocker (99%) and mineralocorticoid receptor antagonist (98%). 56 patients (31%) had a Cardiac Resynchronisation Therapy (CRT) device and 31 (17%) had an Implantable Cardioverter-Defibrillator (ICD). Only 4 patients (2%) had to discontinue treatment completely due to an adverse reaction. Among them, 3 patients sustained an acute kidney injury (AKI) while 1 patient had increased breathlessness. 40 patients (22%) reported symptomatic hypotension which required dose reduction. 7 patients (4%) sustained an AKI. 2 patients reported a rash and 1 patient reported nausea. Figure 1 shows the change in NYHA class after establishment on Sacubitril/Valsartan. Data on change in LVEF post establishment of Sacubitril/Valsartan was available in 124 patients and is shown in figure 2. A total of 133 patients had completed titration of treatment by July 2018 and included in the analysis of 6-month outcome. 13 patients had one HF hospitalisation and all-cause mortality was 4.5% (6 patients). Only 1 patient had heart failure documented as the primary cause of death. Change in NYHA class and LVEF Conclusion In our cohort of well treated HF patients with reduced ejection fraction, 40% of patients experienced an improvement in NYHA class after establishment on Sacubitril/Valsartan while 35% of patients also experienced a significant improvement in LVEF. Treatment was well tolerated and the discontinuation rate was low when managed in a dedicated HF clinic focused on initiation of Sacubitril/Valsartan.

Chronic heart failure (CHF) is a heterogeneous syndrome with a poor prognosis. Aim of the work – to define predictors of body weight (BW) loss in patients with CHF and a reduced left ventricular ejection fraction (LVEF). Materials and methods. 120 patients with stable CHF and LVEF ≤35 %, II-IV NYHA class were examined. Patients were divided into two groups according to the value of BW loss for 6 months: the first group - loss of BW <6 %, the second - ≥ 6 %. Results. Out of the 120 patients who were studied, a BW loss of ≥ 6 % occurred in 59 (49.2 %) patients. According to the results of binary logistic regression, predictors of BW loss of ≥6 % in patients with CHF and LVEF ≤ 35 % were: age, coronary heart disease, anaemia, and the number of hospitalizations over the last year. People with poorer quality of life, bigger number of points on the Beck depression scale and DEFS, with lower levels of physical activity and worse endothelium-dependent vasodilator response; higher sizes of the right atrium, right ventricle, and pulmonary artery systolic pressure, E / E '. Higher levels of C-reactive protein (CRP), uric acid are associated with a risk of losing BW≥6 %. Conclusions. Weight loss ≥ 6 % is observed in 49.2 % of patients with CHF and LVEF≤35 %. According to multivariate analysis, independent predictors of BW loss of ≥6 % in patients with CHF and LVEF≤35 % are age, CRP level, III-IV NYHA class, lower cholesterol levels, as well as lower rates of flow-dependent vasodilator response and hip circumference.

Objective. To identify and evaluate the relationship between the level of proadrenomedullin and clinical and anamnestic data of patients with chronic heart failure of ischemic genesis.Materials and methods. 240 men with chronic forms of coronary heart disease (mean age 55.9 [43; 63] years) and past Q-forming myocardial infarction were examined. Of these, 110 patients had chronic heart failure and preserved left ventricular ejection fraction (group 1) and 130 patients had chronic heart failure and dilatation with a low left ventricular ejection fraction (group 2). In all patients the MR-proADM level in the blood serum was determined.Results. In the control group, the level of MR-proADM was 0.49 [0.18; 0.58] nmol /l. In the meantime, it was statistically significantly higher in the studied groups of patients than in the control group (p < 0.001 and p < 0.001, respectively). And in the group of patients with chronic heart failure and dilatation with a low left ventricular ejection fraction, it was statistically significantly higher than in the group of patients with chronic heart failure and preserved left ventricular ejection fraction (1.72 [1.56; 1.98] nmol/l and 0.89 [0.51; 1.35] nmol/l, respectively, p < 0.038). The study demonstrated the presence of statistically significant associations between the level of MR-proADM and the severity of chronic heart failure and exertional angina pectoris as well as between the presence of a constant form of atrial fibrillation and the levels of systolic and diastolic blood pressure.Conclusion. MR-proADM is a new promising marker, which will be possible to use as a diagnostic standard for assessing the effectiveness of treatment of cardiac patients.

Abstract Aims Current guidelines recommend an implantable cardiac defibrillator (ICD) in patients with symptomatic heart failure and reduced ejection fraction [HFrEF; left ventricular ejection fraction (LVEF) ≤35%] despite ≥3 months of optimal medical therapy. Recent observations demonstrated that sacubitril/valsartan induces beneficial reverse cardiac remodelling in eligible HFrEF patients. Given the pivotal role of LVEF in the selection of ICD candidates, we sought to assess the impact of sacubitril/valsartan on ICD eligibility and its predictors in HFrEF patients. Methods and results We retrospectively evaluated 48 chronic HFrEF patients receiving sacubitril/valsartan and previously implanted with an ICD in primary prevention. We assumed that ICD was no longer necessary if LVEF improved &gt;35% (or &gt; 30% in asymptomatics) at follow-up. Over a median follow-up of 11 months, sacubitril/valsartan induced a significant drop in LV end-systolic volume (−16.7 ml/m2, P = 0.023) and diameter (−6.8 mm, P = 0.022), resulting in a significant increase in LVEF (+3.9%, P &lt; 0.001). As a consequence, 40% of previously implanted patients resulted no more eligible for ICD at follow-up. NYHA class improved in the 50% of population. A dose-dependent effect was noted, with higher doses associated to more reverse remodelling. Among patients deemed no more eligible for ICD, lower NYHA class [odds ratio (OR): 3.73 (95% CI: 1.05–13.24), P = 0.041], better LVEF [OR: 1.23 (95% CI: 1.01–1.48), P = 0.032], and the treatment with the intermediate or high dose of sacubitril/valsartan [OR: 5.60 (1.15–27.1), P = 0.032] were the most important predictors of status change. Conclusions In symptomatic HFrEF patients, sacubitril/valsartan induced beneficial cardiac reverse remodelling and improved NYHA class. These effects resulted in a significant reduction of patients deemed eligible for ICD in primary prevention.

Background. Poge heart-saving decoction (PHSD) has been used as a medicine treating heart failure in China for many years. The study aimed to explore the effect of PHSD on cardiac function in heart failure conditions and its underlying mechanism. Methods. Adriamycin was used to induce the model of heart failure (HF) in rats. Sixty rats were randomly divided into six groups: blank control group, sham group, 9.33 g/kg group (low-PHSD, test group), 13.995 g/kg group (moderate-PHSD, test group), 18.66 g/kg group (high-PHSD, test group), and fosinopril group (4.67 mg/kg, comparison test group). Cardiac ultrasound was used to evaluate the cardiac function of the rats, and radioimmunoassay was used to measure aldosterone (ALD) and angiotensin II (AngII) levels in the serum. Results. Compared with the blank control group, the left ventricular end-diastolic dimension (LVEDd) and left ventricular end-systolic dimension (LVEDs) in the sham group were increased (1.04 ± 0.12 vs. 0.67 ± 0.13 cm; 0.75 ± 0.13 vs. 0.28 ± 0.10 cm; P < 0.05 ), and the left ventricular ejection fraction was decreased (36.65 ± 5.74 vs. 76.09 ± 4.23%; P < 0.05 ). The ejection fraction of HF rats was increased in 9.33 g/kg group, 13.995 g/kg group, and 18.66 g/kg group compared with those of the sham group (57.13 ± 1.63, 58.43 ± 1.98, and 59.21 ± 1.37 vs. 36.65 ± 5.74%; P < 0.05 ). PHSD also improved cardiac function by reducing the LVEDd and LVEDs (0.88 ± 0.11, 0.75 ± 0.13, and 0.72 ± 0.18 vs. 1.04 ± 0.12 cm; 0.62 ± 0.10, 0.63 ± 0.17, and 0.45 ± 0.11 vs. 0.75 ± 0.13 cm; P < 0.05 ). The levels of ALD and AngII in the serum of rats in the sham group were significantly higher than those in the blank control group (371.58 ± 39.25 vs. 237.12 ± 17.35 μg/L; 232.18 ± 16.33 vs. 159.44 ± 18.42 pg/L; P < 0.05 ). The ALD and AngII of the rats in all of the three PHSD groups and the fosinopril group were decreased (276.81 ± 25.63, 277.18 ± 21.35, 268.19 ± 19.28, and 271.47 ± 28.96 vs. 371.58 ± 39.25 μg/L; 169.41 ± 27.53, 168.81 ± 19.78, 164.23 ± 21.34, and 174.27 ± 22.84 vs. 232.18 ± 16.33 pg/L; P < 0.05 ). The histopathological changes of the myocardium in the sham group showed the disorganized fiber, shaded staining, fracture, and zonation. The fracture of the myocardium was relieved in all groups except the sham group and the blank control group. Conclusion. Therefore, PHSD could shorten LVEDd and LVEDs of rats and reverse ventricular remodeling. The mechanism might be related to the inhibition of the activation level of renin-angiotensin-aldosterone system (especially ALD and AngII) and decreasing the postload of the heart.

Aim.To study and analyze the levels of oxidative stress (OS) markers (malondialdehyde (MDA), superoxide dismutase (SOD), advanced oxidation protein products (AOPPs)) depending on the left ventricular ejection fraction (LVEF) and functional class (FC) in patients with chronic heart failure (CHF).Material and methods.We examined 60 somatically healthy individuals and 345 patients with CHF, which were divided into three main groups depending on the LVEF and subgroups depending on FC. The levels of OS markers were determined in blood serum — MDA, SOD and AOPPs.Results.In the group of patients with preserved LVEF and FC II-IV CHF, levels of MDA and AOPPs were statistically significantly higher, and the SOD level was lower compared to the control group. In the group of patients with moderately reduced and reduced LVEF, the levels of MDA and AOPPs were statistically significantly higher, and SOD activity was lower compared with the control group and the group of patients with CHF and preserved LVEF. In patients with CHF with higher FC, there was a statistically significant increase of MDA and AOPPs levels and decrease of SOD activity. The most pronounced changes in the levels of above-mentioned markers were recorded in patients with reduced LVEF. According to the correlation analysis a direct relationship between the levels of markers of the OS and clinical manifestations of the disease was found.Conclusion.Changes in levels of MDA, SOD and AOPPs in patients with CHF were detected already in the early stages of the disease compared with the control group. In patients with higher FC CHF and preserved, moderately reduced and reduced LVEF, a statistically significant increase in the levels of MDA and AOPPs and a decrease of SOD activity were observed. The most pronounced changes in the levels of the markers were indicated in patients with reduced LVEF.
