Background Patients with heart failure and reduced ejection fraction have impaired health-related quality of life (HRQL) with variable responses to therapies that target mortality and heart failure hospitalizations. In PARADIGM-HF trial (Prospective Comparison of ARNI [Angiotensin Receptor-Neprilysin Inhibitor] With ACEI [Angiotensin-Converting-Enzyme Inhibitor] to Determine Impact on Global Mortality and Morbidity in Heart Failure), sacubitril/valsartan reduced morbidity and mortality compared with enalapril. Another major treatment goal is to improve HRQL. Given improvements in mortality with sacubitril/valsartan, this analysis provides comprehensive assessment of impact of therapy on HRQL in survivors only. Methods and Results Patients (after run-in phase) completed disease-specific HRQL using Kansas City Cardiomyopathy Questionnaire (KCCQ) at randomization, 4 month, 8 month, and annual visits. Changes in KCCQ scores were calculated using repeated measures analysis of covariance model that adjusted for treatment and baseline values (principal efficacy prespecified at 8 months). Among the 8399 patients enrolled in PARADIGM-HF, 7623 (91%) completed KCCQ scores at randomization with complete data at 8 months for 6881 patients (90% of baseline). At 8 months, sacubitril/valsartan group noted improvements in both KCCQ clinical summary score (+0.64 versus -0.29; P=0.008) and KCCQ overall summary score (+1.13 versus -0.14; P < 0.001) in comparison to enalapril group and significantly less proportion of patients with deterioration (≥5 points decrease) of both KCCQ scores (27% versus 31%; P=0.01). Adjusted change scores demonstrated consistent improvements in sacubitril/valsartan compared with enalapril through 36 months. Conclusions Change scores in KCCQ clinical summary scores and KCCQ overall summary scores were better in patients treated with sacubitril/valsartan compared with those treated with enalapril, with consistency in most domains, and persist during follow-up beyond 8 months. These findings demonstrate that sacubitril/valsartan leads to better HRQL in surviving patients with heart failure. Clinical Trial Registration URL: http://www.clinicaltrials.gov.

- Natriuretic peptides are substrates of neprilysin; hence, B-type natriuretic peptide (BNP) concentrations rise with neprilysin inhibition. Thus, the clinical validity of measuring BNP in sacubitril/valsartan-treated patients has been questioned, and use of N-terminal pro-B-type natriuretic peptides (NT-proBNP) has been preferred and recommended.The purpose of this study was to determine the prognostic performance of BNP measurements before and during treatment with sacubitril/valsartan.BNP and NT-proBNP were measured before and after 4 to 6weeks, 8 to 10weeks, and 9months of treatment with sacubitril/valsartan in the PARADIGM-HF (Prospective Comparison of ARNI with ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) trial. We assessed the association of levels of these natriuretic peptides with the subsequent risk of cardiovascular death or hospitalization for HF.Median BNP concentration (before treatment: 202ng/l [Q1 to Q3: 126 to 335ng/l]) increased to 235ng/l (Q1to Q3: 128 to 422ng/l) after 8 to 10weeks of treatment. BNP concentrations doubled in 141 (18%) patients and tripled in 49 (6%) patients during the first 8 to 10weeks of sacubitril/valsartan. In contrast, such striking increases in NT-proBNP following the use of the neprilysin inhibitor were extremely rare. Treatment with sacubitril/valsartan causedarightward shift in the distribution of BNP when compared with NT-proBNP, but both peptides retained theirprognostic accuracy (C-statistics of 63% to 67% for BNP and C-statistics of 64% to 70% for NT-proBNP) with nodifference between the 2 biomarkers. Increases in both BNP and NT-proBNP during 8 to 10weeks of sacubitril/valsartanwere associated with worse outcomes (p=0.003 and p=0.005, respectively).Circulating levels of BNP may increase meaningfully early after initiation of sacubitril/valsartan. In comparison, NT-proBNP is not a substrate of neprilysin inhibition, and thus may lead to less clinical confusion when measured within 8 to 10weeks of drug initiation. However, during treatment, either biomarker predicts the risk of major adverse outcomes in patients treated with angiotensin receptor-neprilysin inhibitors.

- Background: While disease modifying therapies exist for heart failure (HF) with reduced left ventricular ejection fraction (LVEF), few options are available for patients in the higher range of LVEF (>40%). Sacubitril/valsartan has been compared with a renin-angiotensin- system (RAS) inhibitor alone in two similarly designed clinical trials of patients with reduced and preserved LVEF, permitting examination of its effects across the full spectrum of LVEF. Methods: We combined data from PARADIGM-HF (LVEF eligibility≤40%; n=8,399) and PARAGON-HF (LVEF eligibility≥45%; n=4,796) in a prespecified pooled analysis. We divided randomized patients into LVEF categories:≤22.5% (n=1269), >22.5% to 32.5% (n=3987), >32.5% to 42.5% (n=3143), > 42.5% to 52.5% (n=1427), > 52.5% to 62.5% (n=2166), >62.5% (n=1202). We assessed time to first cardiovascular death and HF hospitalization, its components, and total heart failure hospitlizations, all-cause mortality and non-cardiovascular mortality. Incidence rates and treatment effects were examined across categories of LVEF. Results: Among 13,195 randomized patients, we observed lower rates of cardiovascular death and HF hospitalization, but similar rates of non-cardiovascular death, among patients in the highest vs. lowest groups. Overall sacubitril/valsartan was superior to RAS inhibition for first cardiovascular death or heart failure hospitalization (HR 0.84, 95% CI 0.78, 0.90), cardiovascular death (HR 0.84, 95% CI 0.76, 0.92), heart failure hospitalization (HR 0.84, 95% CI 0.77, 0.91), and all-cause mortality (HR 0.88, 95% CI 0.81, 0.96). The effect of sacubitril/valsartan was modified by LVEF (treatment-by-continuous LVEF interaction p=0.02), and benefit appeared to be present for individuals with EF primarily below the normal range, although the treatment benefit for cardiovascular death diminished at a lower ejection fraction. We observed effect modification by LVEF on the efficacy of sacubitril/valsartan in both men and women with respect to composite total HF hospitalizations and cardiovascular death, although women derived benefit to higher ejection fractions. Conclusions:The therapeutic effects of sacubitril/valsartan, compared with a RAS inhibitor alone, vary by LVEF, with treatment benefits, particularly for heart failure hospitalization, that appear to extend to patients with heart failure and mildly reduced ejection fraction. These therapeutic benefits appeared to extend to a higher LVEF range in women compared with men.

- Aim Blood urea nitrogen (BUN) to creatinine ratio is associated with worse outcomes in acute heart failure (HF) but little is known about its importance in chronic HF.Methods and results We combined individual patient data from clinical trials (HF with reduced ejection fraction [HFrEF]: PARADIGM-HF, ATMOSPHERE and DAPA-HF, and HF with preserved ejection fraction [HFpEF]: PARAGON-HF and I-PRESERVE). The primary outcome examined was a composite time to first HF hospitalization or cardiovascular death; its components and all-cause death were also examined. Each HF phenotype was categorized according to median BUN/creatinine ratio, generating four groups that is, HFpEF <= and >median BUN/creatinine ratio and HFrEF <= and >median BUN/creatinine ratio. The association between BUN/creatinine ratio and outcomes was evaluated using the Kaplan-Meier estimator and Cox proportional hazard models. Overall, 28 820 patients were analysed. The median (IQR) BUN/creatinine ratio was 20.1 (Q1-Q3 16.7-24.7) in HFpEF and 18.7 (15.2-22.8) in HFrEF. In both HFpEF and HFrEF, higher BUN/creatinine ratio was associated with older age, female sex, and diabetes, but similar estimated glomerular filtration rate (eGFR). The risk of each outcome examined was significantly higher in patients with BUN/creatinine ratio >= median, compared toConclusion Higher BUN/creatinine ratio was associated with worse outcomes in patients with chronic HF across the spectrum of left ventricular ejection fraction, independently of eGFR and NT-proBNP. BUN/creatinine ratio may reflect neurohumoral activation (especially increased arginine vasopressin), altered renal blood flow or other pathophysiologic mechanisms not incorporated in conventional prognostic variables.
