Abstract BACKGROUND Galectin-3 predicts prognosis in heart failure (HF) and may help to select HF patients in need of intensified therapy. METHODS This retrospective post hoc analysis included 219 patients from the Trial of Intensified versus Standard Medical Therapy in Elderly Patients with Congestive Heart Failure (TIME-HF) and 631 patients from Gruppo Italiano per lo Studio della Sopravvivenza nell'Insufficienza Cardiaca (GISSI-HF) with HF who had reduced ejection fraction and available galectin-3 plasma concentrations. The interaction between galectin-3, β-blockers, renin-angiotensin system (RAS) blockade, and spironolactone on outcome was evaluated in TIME-CHF and validated in GISSI-HF. End points were all-cause mortality and the composite of mortality with HF hospitalization or any hospitalization. RESULTS High galectin-3 concentrations were associated with adverse outcome in both cohorts and remained significantly associated with death after multivariate adjustment [hazard ratio 2.42 (95% CI 1.17–5.01), P = 0.02, in TIME-CHF; 1.47 (1.02–2.10), P = 0.04, in GISSI-HF). In TIME-CHF, patients with low galectin-3 plasma concentrations had a better prognosis when β-blockers were up-titrated, whereas patients with high galectin-3 plasma concentrations did not (interaction P < 0.05 for mortality and death with or without hospitalization). Opposite trends were seen for RAS blockade but were not statistically significant. Patients with high galectin-3 plasma concentrations had neutral prognosis when receiving spironolactone, whereas patients with low galectin-3 plasma concentrations had worse prognosis when receiving spironolactone (interaction P < 0.10 for death with or without hospitalization). In the GISSI-HF validation cohort, these interactions were confirmed for β-blockers (P < 0.05 for all end points) and consistent for RAS blockade (P < 0.10 for death with or without hospitalization), but inconsistent for spironolactone. CONCLUSIONS Galectin-3 is a mediocre prognostic marker, and galectin-3 concentrations interact with the treatment effect of β-blockers and possibly RAS blockade in patients with systolic HF.

Aims A recent study suggested that women with heart failure and heart failure reduced ejection fraction might hypothetically need lower doses of angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers ( = renin-angiotensin-system inhibitors) and β-blockers than men to achieve the best outcome. We assessed the current medical treatment of heart failure reduced ejection fraction in men and women in a large contemporary cohort and address the hypothetical impact of changing treatment levels in women. Methods This analysis is part of a large contemporary quality of heart failure care project which includes 5320 (64%) men and 3003 (36%) women with heart failure reduced ejection fraction. Detailed information on heart failure therapy prescription and dosage were collected. Results Women less often received renin-angiotensin-system inhibitors (79% vs 83%, p < 0.01), but more often β-blockers (82% vs 79%, p < 0.01) than men. Differences in guideline-recommended target doses between sexes were relatively small. Implementing a hypothetical sex-specific dosing schedule (at 50% of the current recommended dose in the European Society of Cardiology guidelines in women only) would lead to significantly higher levels of women receiving appropriate dosing (β-blocker 87% vs 54%, p < 0.01; renin-angiotensin-system inhibitor 96% vs 75%, p < 0.01). Most interestingly, the total number of women with >100% of the new hypothetical target dose would be 24% for β-blockers and 52% for renin-angiotensin-system inhibitors, which can be considered as relatively overdosed. Conclusion In this large contemporary heart failure registry, there were significant but relatively small differences in drug dose between men and women with heart failure reduced ejection fraction. Implementation of the hypothetical sex-specific target dosing schedule would lead to considerably more women adequately treated. In contrast, we identified a group of women who might have been relatively overdosed with increased risk of side-effects and intolerance.

Introduction: Heart failure(HF) is a clinical syndrome that is widely prevalent affecting approximately 6.5 million people in the United States. It accounts for the ever-rising health care costs in the US due to recurrent hospitalizations. Despite advancements in medical management, the mortality and the rate of hospitalizations continues to be high with geographic variations and racial disparities. Through this descriptive study, we sought to analyze the health disparities among Hispanic, African American (AA) and Caucasian population in a single-center. Methods: We identified a total of 178 patients with HF with reduced ejection fraction from our outpatient clinic by utilizing the ICD-10 codes. Patients with ejection fraction >50% have been excluded. A retrospective chart review of their ethnic background, medications, and number of heart failure exacerbations per year has been performed. Results: 178 patients (mean age 62 years, 35.56% of females) including Hispanics (n=102), AA(n=44), and Caucasians (n=32) were included in the study. Although all patients were started on Beta-blockers, only 76.4% and 37.2% of Hispanics were started on ACEi/ARBs and spironolactone respectively. Similarly, 72.7% and 45.4% of AA were started on ACEi/ARBs and spironolactone respectively. This is in contrast to Caucasians population, where a majority of patients were on started on GDMT; 90% and 75% were started on ACEi/ARBs and spironolactone respectively. This was also reflected by the number of admissions due to HF exacerbations which ranged from 2-4/year for Hispanics and AA populations and 0-1/year for Caucasians. Conclusions: GDMT for HF is known to reduce heart failure exacerbations, mortality and the ever rising cost of the healthcare system. We have observed that despite recommendations to initiate GDMT in all patients with HF with reduced ejection fraction, racial disparities exist. Physicians should be mindful of initiating GDMT in all patients.

Current clinical guidelines for heart failure (HF) contain a brand new therapeutic strategy for HF with reduced ejection fraction (HFrEF), which is based on neurohumoral modulation through the use of angiotensin receptor neprilysin inhibitors. There is a large body of evidence for the fact that sodium-glucose co-transporter 2 inhibitors may significantly improve all-cause mortality, cardiovascular mortality and hospitalization for HF in patients with HFrEF who received renin–angiotensin system blockers including angiotensin receptor neprilysin inhibitors, β-blockers and mineralocorticoid receptor antagonists. The review discusses that sodium-glucose co-transporter 2 inhibitors have a wide spectrum of favorable molecular effects and contribute to tissue protection, improving survival in HFrEF patients.

Several classes of inhibitors of the renin–angiotensin system were developed as antihypertensive agents. Following the early observations of favourable haemodynamic effects of angiotensin-converting enzyme inhibitors (ACEIs) in patients with congestive heart failure, a series of major randomized outcome trials demonstrated morbidity and mortality benefits of these agents across the spectrum of patients with heart failure with reduced ejection fraction (HFrEF). Angiotensin receptor blockers (ARBs) were then also shown to have similar benefits with a suggestion of some incremental improvements when used together. However, in the trials that randomized patients to a proven dose of an ACEI plus either placebo or an ARB, the combination of the two inhibitors of the renin–angiotensin system resulted in more adverse drug effects without a meaningful improvement in clinical outcomes. This chapter reviews the fundamental underpinnings for use of either an ACEI or ARB to improve prognosis of patients with HFrEF.

Abstract Aims In the DAPA-HF trial, the SGLT2 inhibitor dapagliflozin reduced the risk of worsening heart failure (HF) and death in patients with HF and reduced ejection fraction. We examined whether this benefit was consistent in relation to background HF therapy. Methods and results In this post hoc analysis, we examined the effect of study treatment in the following yes/no subgroups: diuretic, digoxin, mineralocorticoid receptor antagonist (MRA), sacubitril/valsartan, ivabradine, implanted cardioverter-defibrillating (ICD) device, and cardiac resynchronization therapy. We also examined the effect of study drug according to angiotensin-converting enzyme inhibitor/angiotensin receptor blocker dose, beta-blocker (BB) dose, and MRA (≥50% and &lt;50% of target dose). We analysed the primary composite endpoint of cardiovascular death or a worsening HF event. Most randomized patients (n = 4744) were treated with a diuretic (84%), renin–angiotensin system (RAS) blocker (94%), and BB (96%); 52% of those taking a BB and 38% taking a RAS blocker were treated with ≥50% of the recommended dose. Overall, the dapagliflozin vs. placebo hazard ratio (HR) was 0.74 [95% confidence interval (CI) 0.65–0.85] for the primary composite endpoint (P &lt; 0.0001). The effect of dapagliflozin was consistent across all subgroups examined: the HR ranged from 0.57 to 0.86 for primary endpoint, with no significant randomized treatment-by-subgroup interaction. For example, the HR in patients taking a RAS blocker, BB, and MRA at baseline was 0.72 (95% CI 0.61–0.86) compared with 0.77 (95% CI 0.63–0.94) in those not on all three of these treatments (P-interaction 0.64). Conclusion The benefit of dapagliflozin was consistent regardless of background therapy for HF.

Abstract Background Previous investigations of plasma Renin-Angiotensin-System (RAS) fingerprints of patients with heart failure with reduced ejection fraction (HFrEF) revealed the existence of low, medium and high renin phenotypes independently of disease severity. Plasma renin serves as an excellent surrogate for angiotensin levels. The different renin phenotypes could not only hypothetically respond differently to RAS blockade but associated alterations of other vasoactive peptide systems could elucidate disease mechanisms and novel targets for heart failure therapy. The study aimed to investigate the relation between RAS regulation and pathophysiologically relevant vasoactive peptide systems based on different renin phenotypes. Methods We prospectively enrolled 369 patients with stable HFrEF. Laboratory markers including NT-proBNP and active renin concentration (ARC) were assessed. Plasma NEP levels (sNEP), bioactive adrenomedullin (bio-ADM) and big-endothelin1 (bigET-1) were measured by ELISA (R&D systems, UK; Sphingotec GmbH, Germany and Eagle Biosciences, Austria). NEP activity was determined by a fluorimetric peptide cleavage assay. The correlation between biomarkers and association with all-cause mortality was assessed. sNEP, bio-ADM and bigET-1 levels as well as NEP activity between the different renin phenotypes (i.e. <15. percentile, 15.-85. percentile and >85. percentile of ARC) was compared. Results Median age was 65 (IQR 53–73) years, 75% of patients were male. Median NT-proBNP levels were 1936 (IQR 855–4126) pg/mL. Median ARC was 155 (29–569) μIE/mL, the low, medium and high renin HFrEF phenotypes showed median ARC levels of 4.2μIE/mL (IQR 2.0–7.8), 155.1μIE/mL (IQR 43.3–353.5) and 2360μIE/mL (IQR 1483–3250) μIE/mL. Median bigET-1 was 0.62pmol/L (IQR 0.42–1.10), bio-ADM 26.0pg/mL (IQR 16.1–46.7), sNEP 413pg/mL (IQR 0–4111) and NEP activity 2.36nmol/mL/min (IQR 1.16–4.59). There was no correlation between sNEP and NEP activity [r=0.09, p=0.088]. ARC did not show a meaningful correlation with any of the four biomarkers [p=ns for sNEP, NEP activity and bigET-1; r=0.13, p=0.018 for bio-ADM]. In the univariate analysis ARC, bigET-1, bio-ADM but not sNEP and NEP activity, were associated with outcome. This association remained significant after adjustment for age, gender and kidney function for all three markers and for ARC after adding NT-proBNP [adj. HR per 1-IQR increase of ARC 1.27 (95% CI 1.04–1.22), p=0.003]. There were no differences in bigET-1, bio-ADM and sNEP or NEP activity stratified by the different renin phenotypes (Figure1). Figure 1 Conclusions ARC is a risk factor for mortality in HFrEF patients, independently of NT-proBNP. Plasma NEP levels and activity neither correlated with each other nor were associated with outcome. Bio-ADM and bigET-1 were strong risk factors for all-cause mortality. Interestingly, neither NEP nor bio-ADM or bigET-1 were related to RAS-activation, suggesting that there is no direct relationship with RAS regulation.
