The PARADIGM-HF trial identified a marked reduction in the risk of death and hospitalization for heart failure in patients with heart failure with reduced ejection fraction (HFrEF) treated with sacubitril-valsartan, but the physiologic processes underpinning these improvements are unclear. We tested the hypothesis that treatment with sacubitril-valsartan improves peripheral vascular function, functional capacity, and inflammation in patients with HFrEF. We prospectively studied patients with HFrEF (n=11, 10M/1F, left ventricular ejection fraction 27±8%) on optimal, guideline-directed medical treatment who were subsequently prescribed sacubitril-valsartan (open-label, uncontrolled, and unblinded). Peripheral vascular function (brachial artery flow-mediated dilation (FMD, conduit vessel function) and reactive hyperemia (RH, microvascular function)), functional capacity (six-minute walk test (6MWT) distance), and the pro-inflammatory biomarkers, tumor necrosis factor-alpha (TNF-α) and interleukin-18 (IL-18) were obtained at baseline and again at 1, 2, and 3 months of treatment. %FMD improved after 1 month of treatment, and this favorable response persisted for months 2 and 3 (baseline: 3.25±1.75%; 1mo: 5.23±2.36%; 2mo: 5.81±1.79%; 3mo: 6.35±2.77%), while RH remained unchanged. 6MWT distance increased at months 2 and 3 (baseline: 420±92 m; 1mo: 436±98 m; 2mo: 465±115 m; 3mo: 460±110 m), and there was a sustained reduction in TNF-α (baseline: 2.38±1.35 pg/mL; 1mo: 2.06±1.52 pg/mL; 2mo: 1.95±1.34 pg/mL; 3mo: 1.92±1.37 pg/mL) and a reduction in IL-18 at months 3 (baseline: 654±150 pg/mL; 1mo: 595±140 pg/mL; 2mo: 601±176 pg/mL; 3mo: 571±127 pg/mL). This study provides new evidence for the potential of this new drug class to improve conduit vessel function, functional capacity, and inflammation in patients with HFrEF.

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.

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.

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.

Introduction: Impaired vascular function in blacks contributes to a higher risk of heart failure (HF) compared to other race/ethnicities. Hypothesis: Black patients with HF with reduced ejection fraction (HFrEF) will have worse digital microvascular function measured using peripheral arterial tonometry (PAT). High resolution metabolomics profiling will identify novel biomarkers of vascular function. Methods: PAT was used to estimate the reactive hyperemia index (RHI) in blacks and whites with HFrEF (N=154, age: 53.7 ± 13.0 yrs, 48.7% female, 61.0% black) and healthy controls (N=200, age: 43.2 ± 14.0 yrs, 47.0% female, 27.0% black). Linear regression was used to determine if race was associated with RHI after adjustment for traditional CV risk factors. High-resolution plasma metabolomics profiling and pathway analysis, followed by metabolite confirmation with mass spectrometry were used to derive a metabolomics score (MS) from metabolites that were significantly associated with RHI, different between blacks and whites, and attenuated the association of black race with RHI. Results: Black subjects were younger in both the HFrEF and control cohorts. Blacks with HFrEF were more likely to have nonischemic HF and hypertension, more likely to be on hydralazine-nitrates and diuretics. RHI was lower in blacks than whites both in subjects with HFrEF (1.8 ± 0.5 vs. 2.0 ± 0.5, P=0.02) and in healthy controls (2.1 ± 0.5 vs. 2.4 ± 0.5, P=0.003). Black race was independently associated with lower RHI (adjusted β=-0.221, P=0.03). MS comprising metabolites representative of cardiac cachexia (3-Methyl-Histidine, L-Histidine, Creatinine), vascular collagen turnover (4-hydroxyproline), purine metabolism and oxidative stress (uric acid) attenuated the association of black race with RHI by 49.8%. Conclusion: Integration of vascular phenotyping with metabolomic profiling reveals a novel MS that attenuates the association of black race with impaired microvascular function.

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).

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.
