Introduction: Reduced skeletal muscle function link to poor prognosis in patients with chronic heart failure (HF). Irisin is a newly identified muscle-derived protein found in human serum. The gene expression of irisin precursor fibronectin domain containing protein 5 in skeletal muscle is associated with exercise tolerance in HF patients. Hypothesis: Irisin could be a useful biomarker for disease severity and future adverse cardiovascular events in patients with HF with reduced ejection fraction (HFrEF). Methods and results: We measured serum irisin levels in 84 patients with HFrEF. HFrEF was defined as left ventricular ejection fraction≦50% and meet the Framingham criteria of HF. Serum irisin concentrations were measured by ELISA. The endpoint of this study was a composite of total mortality, cardiovascular hospitalization and coronary revascularization. Serum irisin levels were negatively correlated with serum high sensitive troponin T levels (r=-0.24, p=0.048). Right heart catheterization revealed that serum irisin levels had significant negative correlation with pulmonary capillary wedge pressure (r=-0.23, p=0.044). In receiver operating characteristic (ROC) analysis, cut-off values of irisin and BNP for prediction of one-year events were 55.548 ng/mL and 324.8 pg/mL, respectively. Kaplan Meier curve demonstrated that the event-free rate was decreased in the low irisin (≦cut-off value) group (log-rank test p=0.024). The combination of low irisin and high BNP (≧cut-off value) identified patients with a significantly higher probability of adverse events (p=0.008). Multivariate Cox hazard analysis identified low levels of irisin (≦cut-off value) (hazard ratio [HR]: 3.08; 95% confidence interval [CI]: 1.31-7.21, p=0.01) and ischemic etiology (HR: 3.32; 95% CI: 1.50-7.35, p=0.003) as independent predictors of mortality and cardiovascular events. ROC analysis revealed that irisin achieved an area under the curve (AUC) of 0.67 for one-year events (p=0.031), and that the AUC increased when irisin was added to BNP level (alone: 0.64, BNP+irisin: 0.74). Conclusions: Irisin could be a useful biomarker for evaluating disease severity and providing incremental prognostic information in patients with HFrEF.

Aim. To analyze clinical and echocardiographic characteristics and prognosis in patients with heart failure mid-range ejection fraction. Methods. The study included 76 patients with stable heart failure IIV functional class, with a mean age of 66.110.4 years. All patients were divided into 3 subgroups based on the left ventricular ejection fraction: the first group heart failure patients with reduced ejection fraction (below 40%), 21.1%; the second group patients with mid-range ejection fraction (from 40 to 49%), 23.7%; the third group patients with preserved ejection fraction (50%), 55.3%. The clinical characteristics of all groups were compared. The quality of life was assessed by the Minnesota Satisfaction Questionnaire (MSQ), the clinical condition was determined by using the clinical condition assessment scale (Russian Shocks). The prognosis was studied according to the onset of cardiovascular events one year after enrollment in the study. The endpoints were cardiovascular mortality, myocardial infarction (MI), stroke, hospitalization for acutely decompensated heart failure, thrombotic complications. Statistical analysis was performed by using IBM SPSS Statistics 20 software. Normal distribution of the data was determined by the ShapiroWilk test, nominal indicators were compared between groups by using chi-square tests, normally distributed quantitative indicators by ANOVA. The KruskalWallis test was performed to comparing data with non-normal distribution. Results. Analysis showed that the most of clinical characteristics (etiological structure, age, gender, quality of life, results on the clinical condition assessment scale for patients with chronic heart failure and a 6-minute walk test, distribution by functional classes of heart failure) in patients with mid-range ejection fraction (HFmrEF) were similar to those in patients with reduced ejection fraction (HFrEF). At the same time, they significantly differed from the characteristics of patients with preserved ejection fraction (HFpEF). Echocardiographic data from patients with mid-range ejection fraction ranks in the middle compared to patients with reduced and preserved ejection fraction. In heart failure patients with mid-range ejection fraction, the incidence of adverse outcomes during the 1st year also was intermediate between heart failure patients with preserved ejection fraction and patients with reduced ejection fraction: for all cardiovascular events in the absence of significant differences (17.6; 10.8 and 18.8%, respectively), myocardial infarction (5,9; 0 and 6.2%), thrombotic complications (5.9; 5.4 and 6.2%). Heart failure patients with mid-range ejection fraction in comparison to patients with preserved ejection fraction and reduced ejection fraction had significantly lower cardiovascular mortality (0; 2.7 and 12.5%, p 0.05) and the number of hospitalization for acutely decompensated heart failure (0; 2,7 and 6.2%). Conclusion. Clinical characteristics of heart failure patients with mid-range and heart failure patients with reduced ejection fraction are similar but significantly different from those in the group of patients with preserved ejection fraction; echocardiographic data in heart failure patients with mid-range ejection fraction is intermediate between those in patients with reduced ejection fraction and patients with preserved ejection fraction; the prognosis for all cardiovascular events did not differ significantly in the groups depending on the left ventricular ejection fraction.

Objective Evidence

Heart failure with preserved left ventricular ejection fraction (HF-PEF), sometimes named diastolic heart failure, is a common condition most frequently seen in the elderly and is associated with arterial hypertension and left ventricular (LV) hypertrophy. Symptoms are attributed to a stiff left ventricle with compensatory elevation of filling pressure and reduced ability to increase stroke volume by the Frank-Starling mechanism. LV interaction with stiff arteries aggravates these problems. Prognosis is almost as severe as for heart failure with reduced ejection fraction (HF-REF), in part reflecting co-morbidities. Before the diagnosis of HF-PEF is made, non-cardiac etiologies must be excluded. Due to the non-specific nature of heart failure symptoms, it is essential to search for objective evidence of diastolic dysfunction which, in the absence of invasive data, is done by echocardiography and demonstration of signs of elevated LV filling pressure, impaired LV relaxation, or increased LV diastolic stiffness. Antihypertensive treatment can effectively prevent HF-PEF. Treatment of HF-PEF is symptomatic, with similar drugs as in HF-REF.

Neprilysin Inhibitor

The angiotensin receptor–neprilysin inhibitor (ARNI) sacubitril/valsartan and sodium-glucose cotransporter-2 (SGLT-2) inhibitor dapagliflozin have been shown to reduce rehospitalization and cardiac mortality in patients with heart failure (HF) with reduced ejection fraction (HFrEF). We aimed to compare the long-term cardiac and all-cause mortality of ARNI and dapagliflozin combination therapy against ARNI monotherapy in patients with HFrEF. This retrospective study involved 244 patients with HF with New York Heart Association (NYHA) class II–IV symptoms and ejection fraction ≤40%. The patients were divided into 2 groups: ARNI monotherapy and ARNI+dapagliflozin. Median follow-up was 2.5 (.16–3.72) years. One hundred and seventy-five (71.7%) patients were male, and the mean age was 65.9 (SD, 10.2) years. Long-term cardiac mortality rates were significantly lower in the ARNI+dapagliflozin group (7.4%) than in the ARNI monotherapy group (19.5%) ( P = .01). Dapagliflozin [Hazard Ratio (HR) [95% Confidence Interval (CI)] = .29 [.10–.77]; P = .014] and left ventricular ejection fraction (LVEF) [HR (95% CI) = .89 (.85–.93); P < .001] were found to be independent predictors of cardiac mortality. Our study showed a significant reduction in cardiac mortality with ARNI and dapagliflozin combination therapy compared with ARNI monotherapy.

The Impact

Background: The angiotensin receptor-neprilysin inhibitor (ARNI) decreases cardiovascular mortality in patients with chronic heart failure with a reduced ejection fraction (HFrEF). Data regarding the impact of ARNI on the outcome in HFrEF patients according to heart failure etiology are limited. Methods and results: One hundred twenty-one consecutive patients with HFrEF from the years 2016 to 2017 were included at the Medical Centre Mannheim Heidelberg University and treated with ARNI according to the current guidelines. Left ventricular ejection fraction (LVEF) was numerically improved during the treatment with ARNI in both patient groups, that with ischemic cardiomyopathy (n = 61) (ICMP), and that with non-ischemic cardiomyopathy (n = 60) (NICMP); p = 0.25. Consistent with this data, the NT-proBNP decreased in both groups, more commonly in the NICMP patient group. In addition, the glomerular filtration rate (GFR) and creatinine changed before and after the treatment with ARNI in both groups. In a one-year follow-up, the rate of ventricular tachyarrhythmias (ventricular tachycardia and ventricular fibrillation) tended to be higher in the ICMP group compared with the NICMP group (ICMP 38.71% vs. NICMP 17.24%; p = 0.07). The rate of one-year all-cause mortality was similar in both groups (ICMP 6.5% vs. NICMP 6.6%; log-rank = 0.9947). Conclusions: This study shows that, although the treatment with ARNI improves the LVEF in ICMP and NICMP patients, the risk of ventricular tachyarrhythmias remains higher in ICMP patients in comparison with NICMP patients. Renal function is improved in the NICMP group after the treatment. Long-term mortality is similar over a one-year follow-up.

Высокая распространенность хронической сердечной недостаточности (ХСН) в популяции пожилых пациентов наряду с устойчивым ро- стом численности пожилого населения как в России, так и в западных странах все больше привлекает внимание врачей к проблеме, связан- ной с ведением данного заболевания. Известно, что ведущим фактором риска развития ХСН является повышенное артериальное давление (АД) и большинство пациентов с ХСН имеют в анамнезе артериальную гипертонию (АГ), поэтому лечение пациентов пожилого возраста c АГ и ХСН является одним из важных направлений в профилактике прогрессирования ХСН, снижения количества госпитализаций и смерт- ности. Лечение АГ у пожилых имеет свои особенности, связанные с функциональным статусом пациентов и их способностью переносить лечение. В европейских рекомендациях (2018) пересмотрены целевые цифры АД при лечении АГ у пожилых, однако данные по целевым цифрам АД для лечения АГ у пациентов с ХСН опираются лишь на исследования, проводившиеся у больных без ХСН. Данные об оптималь- ном целевом уровне у пациентов с АГ и ХСН представлены в единичных исследованиях. В настоящей статье проанализирована взаимосвязь уровня АД и сердечно-сосудистых событий и смертности отдельно для пациентов с АГ и сердечной недостаточностью с низкой фракцией выброса левого желудочка и с сохраненной фракцией выброса левого желудочка. Результаты многих исследований показывают, что более низкий уровень систолического АД (120 мм рт. ст.) и диастолического АД (80 мм рт. ст.) ассоциирован с развитием неблагоприятных сердечно-сосудистых событий, особенно у пациентов с сердечной недостаточностью с низкой фракцией выброса левого желудочка.The high prevalence of chronic heart failure (CHF) in the elderly patients, along with the steady growth of the elderly population, both in Russia and in Western countries, is increasingly attracting the attention of doctors to the problem associated with the management of this disease. It is known that the leading risk factor for CHF is high blood pressure (BP) and most patients with CHF have a history of hypertension (H), so the treatment of elderly patients with H and CHF is the major focus in the slowing CHF progression, reducing the heart failure hospitalisation and mortality. Treatment of hypertension in the elderly has some specific features associated with the functional status of patients and their ability to tolerate treatment. The European recommendations (2018) revised target blood pressure levels in the elderly patients, however, data on target blood pressure levels in patients with CHF are based only on studies conducted in patients without CHF, data on the optimal target blood pressure levels in patients with hypertension and CHF are presented in single studies. In this article we analyze the relationship between blood pressure levels and cardiovascular events and mortality separately for patients with hypertension and heart failure with reduced ejection fraction and with preserved ejection fraction. Several studies show that lower systolic blood pressure (120 mm Hg) and diastolic blood pressure (80 mm Hg) is associated with the increased risk of cardiovascular events, especially in patients with heart failure with reduced ejection fraction.

Heart failure (HF) and atrial fibrillation (AF) are the most common cardiovascular conditions in clinical practice and frequently coexist. The number of patients with HF and AF is increasing every year.Aim. To analyze the effect of clinical course and management of HF and AF on the outcomes.Material and methods. The data of 1,003 patients from the first Russian register of patients with HF and AF (RIF-CHF) were analyzed. The endpoints included hospitalization due to decompensated HF, cardiovascular mortality, thromboembolic events, and major bleeding. Predictors of unfavorable outcomes were analyzed separately for patients with HF with preserved ejection fraction (AF+HFpEF), mid-range ejection fraction (AF+HFmrEF), and reduced ejection fraction (AF+HFrEF).Results. Among all patients with HF, 39% had HFpEF, 15% — HFmrEF, and 46% — HFrEF. A total of 57,2% of patients were rehospitalized due to decompensated HF within one year. Hospitalization risk was the highest for HFmrEF patients (66%, p=0,017). Reduced ejection fraction was associated with the increased risk of cardiovascular mortality (15,5% vs 5,4% in other groups, p<0,001) but not ischemic stroke (2,4% vs 3%, p=0,776). Patients with HFpEF had lower risk to achieve the composite endpoint (stroke+MI+cardiovascular death) as compared to patients with HFmrEF and HFrEF (12,7% vs 22% and 25,5%, p<0,001). Regression logistic analysis revealed that factors such as demographic characteristics, disease severity, and selected therapy had different effects on the risk of unfavorable outcomes depending on ejection fraction group.Conclusion. Each group of patients with different ejection fractions is characterized by its own pattern of factors associated with unfavorable outcomes. The demographic and clinical characteristics of patients with mid-range ejection fraction demonstrate that these patients need to be studied as a separate cohort.

The Impact

The treatment with sacubitril/valsartan in patients suffering from chronic heart failure with reduced ejection fraction increases left ventricular ejection fraction and decreases the risk of sudden cardiac death. We conducted a retrospective analysis regarding the impact of age differences on the treatment outcome of sacubitril/valsartan in patients with chronic heart failure with reduced ejection fraction. Patients were defined as adults if ≤65 years (n = 51) and older if >65 years of age (n = 76). The incidence of ventricular arrhythmias at 1-year follow-up was comparable in both groups (30.8 vs 26.5%; p = 0.71). The mortality rate in adult patients is significantly lower as compared with older patients (2 vs 14.5%; log-rank = 0.04). Older patients may suffer remarkably more side effects than adult patients (21.1 vs 11.8%; p = 0.03).

New Treatments

Heart failure (HF) is a common condition with an increasing prevalence. Despite a variety of evidence-based treatments for patients with HF with reduced ejection fraction, morbidity and mortality rates remain high. Furthermore, there are currently no treatments that have yet been shown to reduce complication and death rates in patients who have HF with preserved ejection fraction. Hypertension is a common comorbidity in patients with HF, contributing to disease development and prognosis. For example, hypertension is closely associated with the development of left ventricular hypertrophy, which an important precursor of HF. In particular, nighttime blood pressure (BP) appears to be an important, modifiable risk factor. Both nighttime BP and an abnormal circadian pattern of nighttime BP dipping have been shown to predict development of HF and the occurrence of cardiovascular events, independent of office BP. Key mechanisms for this association include sodium handling/salt sensitivity and increased sympathetic activation. These pathogenic mechanisms are targeted by several new treatment options, including sodium-glucose cotransporter 2 inhibitors, angiotensin receptor neprilysin inhibitors, mineralocorticoid receptor antagonists, and renal denervation. All of these could form part of antihypertensive strategies designed to control nighttime BP and contribute to the goal of achieving perfect 24-hour BP management. Nevertheless, additional research is needed to determine the effects of reducing nighttime BP and improving the circadian BP profile on the rate of HF, other cardiovascular events, and mortality.

Background: Reduced exercise capacity in patients with heart failure (HF) could be partially explained by skeletal muscle dysfunction. We compared skeletal muscle function, structure, and metabolism among clinically stable outpatients with HF with preserved ejection fraction, HF with reduced ejection fraction, and healthy controls (HC). Furthermore, the molecular, metabolic, and clinical profile of patients with reduced muscle endurance was described. Methods: Fifty-five participants were recruited prospectively at the University Hospital Jena (17 HF with preserved ejection fraction, 18 HF with reduced ejection fraction, and 20 HC). All participants underwent echocardiography, cardiopulmonary exercise testing, 6-minute walking test, isokinetic muscle function, and skeletal muscle biopsies. Expression levels of fatty acid oxidation, glucose metabolism, atrophy genes, and proteins as well as inflammatory biomarkers were assessed. Mitochondria were evaluated using electron microscopy. Results: Patients with HF with preserved ejection fraction showed compared with HF with reduced ejection fraction and HC reduced muscle strength (eccentric extension: 13.3±5.0 versus 18.0±5.9 versus 17.9±5.1 Nm/kg, P =0.04), elevated levels of MSTN-2 (myostatin-2), FBXO-32 (F-box only protein 32 [Atrogin1]) gene and protein, and smaller mitochondrial size ( P <0.05). Mitochondrial function and fatty acid and glucose metabolism were impaired in HF-patients compared with HC ( P <0.05). In a multiple regression analysis, GDF-15 (growth and differentiation factor 15), CPT1B (carnitine palmitoyltransferase IB)-protein and oral anticoagulation were independent factors for predicting reduced muscle endurance after adjusting for age (log10 GDF-15 [pg/mL] [B, −54.3 (95% CI, −106 to −2.00), P =0.043], log10 CPT1B per fold increase [B, 49.3 (95% CI, 1.90–96.77), P =0.042]; oral anticoagulation present [B, 44.8 (95% CI, 27.90–61.78), P <0.001]). Conclusions: Patients with HF with preserved ejection fraction have worse muscle function and predominant muscle atrophy compared with those with HF with reduced ejection fraction and HC. Inflammatory biomarkers, fatty acid oxidation, and oral anticoagulation were independent factors for predicting reduced muscle endurance.
