RESUMEN
BACKGROUND: The PIONEER-HF (comParIson Of sacubitril/valsartaN versus Enalapril on Effect on nt-pRo-bnp in patients stabilized from an acute Heart Failure episode) trial demonstrated the efficacy and safety of sacubitril/valsartan (S/V) in stabilized patients with acute decompensated heart failure (HF) and reduced ejection fraction. OBJECTIVES: The study sought to determine whether and how prior HF history and treatment with an angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) affected the results. METHODS: The PIONEER-HF trial was a prospective, multicenter, double-blind, randomized clinical trial enrolling 881 patients with an ejection fraction ≤40%. Patients were randomly assigned 1:1 to in-hospital initiation of S/V (n = 440) versus enalapril (n = 441). Pre-specified subgroup analyses were performed based on prior HF history (i.e., de novo HF vs. worsening chronic HF) and treatment with an ACE inhibitor or ARB (i.e., ACE inhibitor or ARB-yes vs. ACE inhibitor or ARB-no) at admission. RESULTS: At enrollment, 303 (34%) patients presented with de novo HF and 576 (66%) patients with worsening chronic HF. A total of 421 (48%) patients had been treated with an ACE inhibitor or ARB, while 458 (52%) had not been treated with an ACE inhibitor or ARB. N-terminal pro-B-type natriuretic peptide declined significantly in all 4 subgroups (p < 0.001), with greater decreases in the S/V versus the enalapril arm (p < 0.001). There was no interaction between prior HF history (p = 0.350) or ACE inhibitor or ARB treatment (p = 0.880) and the effect of S/V versus enalapril on cardiovascular death or rehospitalization for HF. The incidences of adverse events were comparable between S/V and enalapril across all 4 subgroups. CONCLUSIONS: Among patients admitted for acute decompensated HF, S/V was safe and well tolerated, led to a significantly greater reduction in N-terminal pro-B-type natriuretic peptide, and improved clinical outcomes compared with enalapril irrespective of previous HF history or ACE inhibitor or ARB treatment.

Importance: In PIONEER-HF, among stabilized patients with acute decompensated heart failure (ADHF), the in-hospital initiation of sacubitril/valsartan was well tolerated and led to improved outcomes compared with enalapril. However, there are limited data comparing the strategies of in-hospital vs postdischarge initiation of sacubitril/valsartan. Objective: To describe changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in patients recently hospitalized for ADHF and switching from taking enalapril to taking sacubitril/valsartan after discharge and compare clinical outcomes for patients randomized to receive in-hospital initiation of sacubitril/valsartan vs in-hospital initiation of enalapril who later switched to taking sacubitril/valsartan during an open-label extension phase. Interventions: Sacubitril/valsartan titrated to 97/103 mg twice daily. Design, Setting, and Participants: The PIONEER-HF trial was a multicenter, randomized, double-blind, active-controlled trial conducted at 129 US sites between May 2016 and May 2018 that compared the in-hospital initiation of sacubitril/valsartan vs enalapril (titrated to target dose, 10 mg twice daily) for 8 weeks among patients admitted for ADHF with reduced ejection fraction and hemodynamic stability. All patients were to continue in a 4-week, open-label study of sacubitril/valsartan; of 881 patients enrolled in PIONEER-HF, 832 (94%) continued in the open-label study. Main Outcomes and Measures: Changes in NT-proBNP levels from week 8 to 12 as well as the exploratory composite of heart failure rehospitalization or cardiovascular death from randomization through week 12. Results: Of 881 participants, 226 (27.7%) were women, 487 (58.5%) were white, 297 (35.7%) were black, 15 (1.8%) were Asian, and 73 (8.8%) were of Hispanic ethnicity; the mean (SD) age was 61 (14) years. For patients who continued to take sacubitril/valsartan, NT-proBNP levels declined -17.2% (95% CI, -3.2 to -29.1) from week 8 to 12. The NT-proBNP levels declined to a greater extent for those switching from taking enalapril to sacubitril/valsartan after the week 8 visit (-37.4%; 95% CI, -28.1 to -45.6; P < .001; comparing changes in 2 groups). Over the entire 12 weeks of follow-up, patients that began taking sacubitril/valsartan in the hospital had a lower hazard for the composite outcome compared with patients that initiated enalapril in the hospital and then had a delayed initiation of sacubitril/valsartan 8 weeks later (hazard ratio, 0.69; 95% CI 0.49-0.97). Conclusions and Relevance: Switching patients' treatment from enalapril to sacubitril/valsartan at 8 weeks after randomization led to a further 37% reduction in NT-proBNP levels in patients with heart failure with reduced ejection fraction and a recent hospitalization for ADHF.

Underuse of hydralazine/nitrate (HYD/NIT) in black patients with heart failure and reduced ejection fraction (HFrEF) has been previously described, but whether this important treatment gap persists in contemporary practice is unknown. Sacubitril/valsartan has become a part of guideline-directed medical therapy for HFrEF but data on utilization of this therapy in black patients is lacking. This study addressed these issues by assessing the frequency of HYD/NIT and sacubitril/valsartan use in black patients with HFrEF in the Change the Management of Patients with Heart Failure Registry, a multicenter cohort study. The association of race with utilization rates of these agents was also evaluated. Clinical and medication data at baseline and during 12 months of follow-up from black and nonblack registry patients without documented contraindications or intolerance to the medications of interest were analyzed. Data were available from December 2015 to October 2017, in 4,848 HFrEF patients, of whom 853 were black (18%) and 3995 were nonblack. Black patients were younger, more likely to be female, and had lower ejection fractions compared with nonblacks. Only 11% of black patients were receiving HYD/NIT therapy at baseline and 13% at 1 year. The percentage of black patients treated at baseline with sacubitril/valsartan was also low at 18% and remained unchanged at 1 year. After adjustment for covariates, race was independently associated with HYD/NIT use (odds ratio 8.32; 95% confidence interval 6.12 to 11.3; p < 0.0001), but not for sacubitril/valsartan. In conclusion, study findings demonstrate a marked persistent treatment gap for HYD/NIT and similar poor utilization of sacubitril/valsartan in black patients with HFrEF despite current guideline recommendations.

AIMS: Limited data are available regarding the ability of sacubitril/valsartan to provide clinically meaningful health-related quality of life (HRQoL) improvements among individuals with heart failure (HF). Objective measurement of physical activity and sleep using actigraphy can provide insight into daily functioning and HRQoL. METHODS AND RESULTS: We designed an 18 week, multicenter, randomized, double-blind, double-dummy, parallel-group study to objectively assess changes in function and HRQoL directly after initiating sacubitril/valsartan vs. enalapril in participants with HF in their home environments. A total of 136 outpatient, ambulatory participants with New York Heart Association Class II or III HF with reduced ejection fraction (HFrEF) will be included in the study. Patients will undergo a 2 week baseline observational phase (continuing current HF treatment); data from the second week of this phase will be the baseline value for comparison with those of subsequent periods. Patients will then enter an 8 week blinded-treatment phase (randomly assigned 1:1 to sacubitril/valsartan or enalapril), followed by an 8 week open-label extension phase (treatment with only sacubitril/valsartan). The primary efficacy endpoint is the change in mean activity counts during the most active 30 min of the participant's day between baseline and the final randomized treatment phase measurement. Secondary endpoints include the change in mean sleep activity during the randomized and open-label phases; questionnaires will also assess HRQoL measures. Rather than analysing pooled actigraphy data, the researchers are considering each participant to be acting as his or her own control. CONCLUSIONS: This will be the first study to assess the effects of sacubitril/valsartan on objective measures of sleep and activity in individuals with HFrEF within the context of their daily lives. Wearable accelerometer devices will be used to gain insight into how the medication affects physical activity and sleep.

IMPORTANCE: In patients with heart failure and reduced ejection fraction (HFrEF), treatment with sacubitril-valsartan reduces N-terminal pro-b-type natriuretic peptide (NT-proBNP) concentrations. The effect of sacubitril-valsartan on cardiac remodeling is uncertain. OBJECTIVE: To determine whether NT-proBNP changes in patients with HFrEF treated with sacubitril-valsartan correlate with changes in measures of cardiac volume and function. DESIGN, SETTING, AND PARTICIPANTS: Prospective, 12-month, single-group, open-label study of patients with HFrEF enrolled in 78 outpatient sites in the United States. Sacubitril-valsartan was initiated and the dose adjusted. Enrollment commenced on October 25, 2016, and follow-up was completed on October 22, 2018. EXPOSURES: NT-proBNP concentrations among patients treated with sacubitril-valsartan. MAIN OUTCOMES AND MEASURES: The primary outcome was the correlation between changes in log2-NT-proBNP concentrations and left ventricular (LV) EF, LV end-diastolic volume index (LVEDVI), LV end-systolic volume index (LVESVI), left atrial volume index (LAVI), and ratio of early transmitral Doppler velocity/early diastolic annular velocity (E/e') at 12 months. RESULTS: Among 794 patients (mean age, 65.1 years; 226 women [28.5%]; mean LVEF = 28.2%), 654 (82.4%) completed the study. The median NT-proBNP concentration at baseline was 816 pg/mL (interquartile range [IQR], 332-1822) and 455 pg/mL (IQR, 153-1090) at 12 months (difference, P < .001). At 12 months, the change in log2-NT-proBNP concentration was correlated with changes in LVEF (r = -0.381 [IQR, -0.448 to -0.310]; P < .001), LVEDVI (r = 0.320 [IQR, 0.246 to 0.391]; P < .001), LVESVI (r = 0.405 [IQR, 0.335 to 0.470]; P < .001), LAVI (r = 0.263 [IQR, 0.186 to 0.338]; P < .001), and E/e' (r = 0.269 [IQR, 0.182 to 0.353]; P < .001). At 12 months, LVEF increased from 28.2% to 37.8% (difference, 9.4% [95% CI, 8.8% to 9.9%]; P < .001), while LVEDVI decreased from 86.93 to 74.15 mL/m2 (difference, -12.25 mL/m2 [IQR, -12.92 to -11.58]; P < .001) and LVESVI decreased from 61.68 to 45.46 mL/m2 (difference, -15.29 mL/m2 [95% CI, -16.03 to -14.55]; P < .001). LAVI and E/e' ratio also decreased significantly. The most frequent adverse events were hypotension (17.6%), dizziness (16.8%), hyperkalemia (13.2%), and worsening kidney function (12.3%). CONCLUSIONS AND RELEVANCE: In this exploratory study of patients with HFrEF treated with sacubitril-valsartan, reduction in NT-proBNP concentration was weakly yet significantly correlated with improvements in markers of cardiac volume and function at 12 months. The observed reverse cardiac remodeling may provide a mechanistic explanation for the effects of sacubitril-valsartan in patients with HFrEF.

RESUMEN
IMPORTANCE: Compared with enalapril, sacubitril-valsartan reduces cardiovascular mortality and heart failure hospitalization in patients with heart failure and reduced ejection fraction (HFrEF). These benefits may be related to effects on hemodynamics and cardiac remodeling. OBJECTIVE: To determine whether treatment of HFrEF with sacubitril-valsartan improves central aortic stiffness and cardiac remodeling compared with enalapril. DESIGN, SETTING, AND PARTICIPANTS: Randomized, double-blind clinical trial of 464 participants with heart failure and ejection fraction of 40% or less enrolled across 85 US sites between August 17, 2016, and June 28, 2018. Follow-up was completed on January 26, 2019. INTERVENTIONS: Randomization (1:1) to sacubitril-valsartan (n = 231; target dosage, 97/103 mg twice daily) vs enalapril (n = 233; target dosage, 10 mg twice daily) for 12 weeks. MAIN OUTCOMES AND MEASURES: The primary outcome was change from baseline to week 12 in aortic characteristic impedance (Zc), a measure of central aortic stiffness. Prespecified secondary outcomes included change from baseline to week 12 in N-terminal pro-B-type natriuretic peptide, ejection fraction, global longitudinal strain, mitral annular relaxation velocity, mitral E/e' ratio, left ventricular end-systolic and end-diastolic volume indexes (LVESVI and LVEDVI), left atrial volume index, and ventricular-vascular coupling ratio. RESULTS: Of 464 validly randomized participants (mean age, 67.3 [SD, 9.1] years; 23.5% women), 427 completed the study. At 12 weeks, Zc decreased from 223.8 to 218.9 dyne × s/cm5 in the sacubitril-valsartan group and increased from 213.2 to 214.4 dyne × s/cm5 in the enalapril group (treatment difference, -2.2 [95% CI, -17.6 to 13.2] dyne × s/cm5; P = .78). Of 9 prespecified secondary end points, no significant between-group difference in change from baseline was seen in 4, including left ventricular ejection fraction (34%-36% with sacubitril-valsartan vs 33 to 35% with enalapril; treatment difference, 0.6% [95% CI, -0.4% to 1.7%]; P = .24). However, greater reductions from baseline were seen with sacubitril-valsartan than with enalapril in all others, including left atrial volume (from 30.4 mL/m2 to 28.2 mL/m2 vs from 29.8 mL/m2 to 30.5 mL/m2; treatment difference, -2.8 mL/m2 [95% CI, -4.0 to -1.6 mL/m2]; P < .001), LVEDVI (from 75.1 mL/m2 to 70.3 mL/m2 vs from 79.1 mL/m2 to 75.6 mL/m2; treatment difference, -2.0 mL/m2 [95% CI, -3.7 to 0.3 mL/m2]; P = .02), LVESVI (from 50.8 mL/m2 to 46.3 mL/m2 vs from 54.1 to 50.6 mL/m2; treatment difference, -1.6 mL/m2 [95% CI, -3.1 to -0.03 mL/m2]; P = .045), and mitral E/e' ratio (from 13.8 to 12.3 vs from 13.4 to 13.8; treatment difference, -1.8 [95% CI, -2.8 to -0.8]; P = .001). Rates of adverse events including hypotension (1.7% vs 3.9%) were similar in both groups. CONCLUSIONS AND RELEVANCE: Treatment of HFrEF with sacubitril-valsartan, compared with enalapril, did not significantly reduce central aortic stiffness. The study findings may provide insight into mechanisms underlying the effects of sacubitril-valsartan in HFrEF. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02874794.
RESUMEN
OBJECTIVES: This study sought to describe the short-term health status benefits of angiotensin-neprilysin inhibitor (ARNI) therapy in patients with heart failure and reduced ejection fraction (HFrEF). BACKGROUND: Although therapy with sacubitril/valsartan, a neprilysin inhibitor, improved patients' health status (compared with enalapril) at 8 months in the PARADIGM-HF (Prospective Comparison of ARNI with ACE inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure) study, the early impact of ARNI on patients' symptoms, functions, and quality of life is unknown. METHODS: Health status was assessed by using the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ) in 3,918 outpatients with HFrEF and left ventricular ejection fraction ≤40% across 140 U.S. centers in the CHAMP-HF (Change the Management of Patients with Heart Failure) registry. ARNI therapy was initiated in 508 patients who were matched 1:2 to 1,016 patients who were not initiated on ARNI (no-ARNI), using a nonparsimonious time-dependent propensity score (6 sociodemographic factors, 23 clinical characteristics), prior KCCQ overall summary (KCCQ-OS) score, and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker status. RESULTS: Multivariate linear regression demonstrated a greater mean improvement in KCCQ-OS in patients initiated on ARNI therapy (5.3 ± 19 vs. 2.5 ± 17.4, respectively; p < 0.001) over a median (interquartile range [IQR]) of 57 (32 to 104) days. The proportions of ARNI versus no-ARNI groups with ≥10-point (large) and ≥20-point (very large) improvements in KCCQ-OS were 32.7% versus 26.9%, respectively, and 20.5% versus 12.1%, respectively, consistent with numbers needed to treat of 18 and 12, respectively. CONCLUSIONS: In routine clinical care, ARNI therapy was associated with early improvements in health status, with 20% experiencing a very large health status benefit compared with 12% who were not started on ARNI therapy. These findings support the use of ARNI to improve patients' symptoms, functions, and quality of life.

OBJECTIVES: The aim of this study was to use a multicenter, observational outpatient registry of patients with heart failure with reduced ejection fraction (HFrEF) to describe the association between changes in patients' medications with changes in health status. BACKGROUND: Alleviating symptoms and improving function and quality of life for patients with HFrEF are primary treatment goals and potential indicators of quality. Whether titrating medications in routine clinical care improves patients' health status is unknown. METHODS: The association of any change in HFrEF medications with 3-month change in health status, as measured using the 12-item Kansas City Cardiomyopathy Questionnaire Overall Summary Scale, was determined in unadjusted and multivariate-adjusted (25 clinical characteristics, baseline health status) models using hierarchical linear regression. RESULTS: Among 3,313 outpatients with HFrEF from 140 centers, 21.9% had medication changes. Three months later, 23.7% and 46.4% had clinically meaningfully worse (≥5-point decrease) and improved (≥5-point increase) Kansas City Cardiomyopathy Questionnaire Overall Summary Scale scores. The 3-month median change in Kansas City Cardiomyopathy Questionnaire Overall Summary Scale score for patients whose HFrEF medications were changed was significantly larger (7.3 points; interquartile range: -3.1 to 20.8 points) than in patients whose medications were not changed (3.1 points; interquartile range: -4.7 to 12.5 points) (adjusted difference 3.0 points; 95% confidence interval: 1.4 to 4.6 points; p < 0.001). Among patients whose medications were adjusted, 26% had very large clinical improvement (≥20 points) compared with 14% whose regimens were not changed. CONCLUSIONS: In routine care of patients with HFrEF, changes in HFrEF medications were associated with significant improvements in patients' health status, suggesting that health status-based performance measures can quantify the benefits of titrating medicines in patients with HFrEF.

AIMS: Circulating high-sensitivity cardiac troponin (hsTn) and soluble ST2 (sST2) reflect myocardial stress in patients with heart failure (HF). Production of cyclic guanosine 3'5' monophosphate (cGMP) in response to activation of natriuretic peptide receptors reduces cardiac afterload and preload. We assessed the effects of sacubitril/valsartan on these biomarkers in patients with reduced ejection fraction and acute decompensated HF (ADHF). METHODS AND RESULTS: PIONEER-HF was a randomized, double-blind trial of sacubitril/valsartan vs. enalapril in hospitalized patients with ADHF following haemodynamic stabilization. We measured circulating hsTnT, sST2, and urinary cGMP at baseline, 1, 2 (sST2, cGMP), 4, and 8 weeks (n = 694 with all baseline biomarkers). Ratios of geometric means (timepoint/baseline) were determined and compared as a ratio for sacubitril/valsartan vs. enalapril. Compared with enalapril, sacubitril/valsartan led to a significantly greater decline in hsTnT and sST2. This effect emerged as early as 1 week for sST2 and was significant for both at 4 weeks with a 16% greater reduction in hsTnT (P < 0.001) and 9% greater reduction in sST2 (P = 0.0033). Serial urinary cGMP increased with sacubitril/valsartan compared with enalapril (P < 0.001, 1 week). The significant differences between treatment groups for each biomarker were sustained at 8 weeks. In an exploratory multivariable-adjusted analysis of cardiovascular death or HF-rehospitalization, the concentrations of hsTnT, sST2 at week 1 were significantly associated with subsequent outcome. CONCLUSION: Biomarkers of myocardial stress are elevated in patients with ADHF and associated with outcome. Compared with enalapril, sacubitril/valsartan reduces myocardial injury and haemodynamic stress as reflected by biomarkers, with an onset that is apparent within 1-4 weeks.

BACKGROUND: Guidelines recommend that patients with heart failure with reduced ejection fraction (HFrEF) have medical therapy titrated to target doses derived from clinical trials, as tolerated. The degree to which titration occurs in contemporary U.S. practice is unknown. OBJECTIVES: This study sought to characterize longitudinal titration of HFrEF medical therapy in clinical practice and to identify associated factors and reasons for medication changes. METHODS: Among 2,588 U.S. outpatients with chronic HFrEF in the CHAMP-HF (Change the Management of Patients with Heart Failure) registry with complete medication data and no contraindications to medical therapy, use and dose of angiotensin-converting enzyme inhibitor (ACEI)/angiotensin II receptor blocker (ARB), angiotensin receptor-neprilysin inhibitor (ARNI), beta-blocker, and mineralocorticoid receptor antagonist (MRA) were examined at baseline and at 12-month follow-up. RESULTS: At baseline, 658 (25%), 525 (20%), 287 (11%), and 45 (2%) patients were receiving target doses of MRA, beta-blocker, ACEI/ARB, and ARNI therapy, respectively. At 12 months, proportions of patients with medication initiation or dose increase were 6% for MRA, 10% for beta-blocker, 7% for ACEI/ARB, and 10% for ARNI; corresponding proportions with discontinuation or dose decrease were 4%, 7%, 11%, and 3%, respectively. Over 12 months, <1% of patients were simultaneously treated with target doses of ACEI/ARB/ARNI, beta-blocker, and MRA. In multivariate analysis, across the classes of medications, multiple patient characteristics were associated with a higher likelihood of initiation or dose increase (e.g., previous HF hospitalization, higher blood pressure, lower ejection fraction) and discontinuation or dose decrease (e.g., previous HF hospitalization, impaired quality of life, more severe functional class). Medical reasons were the most common reasons for discontinuations and dose decreases of each therapy, but the relative contributions from patient preference, health team, and systems-based reasons varied by medication. CONCLUSIONS: In this contemporary U.S. registry, most eligible HFrEF patients did not receive target doses of medical therapy at any point during follow-up, and few patients had doses increased over time. Although most patients had no alterations in medical therapy, multiple clinical factors were independently associated with medication changes. Further quality improvement efforts are urgently needed to improve guideline-directed medication titration for HFrEF.

OBJECTIVES: This study sought to determine the rate of use of target doses of foundational guideline-directed medical therapy (GDMT) in a contemporary cohort of patients with heart failure with reduced ejection fraction (HFrEF) across systolic blood pressure (SBP) categories. BACKGROUND: Patients with HFrEF are infrequently titrated to recommended doses of GDMT. The relationship between SBP and achieving GDMT target doses is not well studied. METHODS: Patients enrolled in the CHAMP-HF (Change the Management of Patients With Heart Failure) registry without documented intolerance to angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), angiotensin receptor-neprilysin inhibitors (ARNIs), and beta blockers (BBs) were assessed at enrollment. We estimated the proportion receiving target doses (% of target dose [95% confidence interval (CI)]) based on the most recent American College of Cardiology/American Heart Association/Heart Failure Society of America heart failure guidelines at baseline in all patients, and by SBP category (≥110 vs. <110 mm Hg). RESULTS: Of the 3,095 patients eligible for analysis, 2,421 (78.2%) had SBP ≥110 mm Hg. The proportion of patients receiving target doses were 18.7% (95% CI: 17.3% to 20.0%; BB), 10.8% (95% CI: 9.7% to 11.9%; ACEI/ARB), and 2.0% (95% CI: 1.5% to 2.5%; ARNI). Among those with SBP <110 mm Hg (n = 674), 17.5% (95% CI: 14.6% to 20.4%; BB), 6.2% (95% CI: 4.4% to 8.1%; ACEI/ARB), and 1.8% (95% CI: 0.8% to 2.8%; ARNI) were receiving target doses. Among those with SBP ≥110 mm Hg (n = 2,421), 19.0% (95% CI: 17.4% to 20.6%; BB), 12.1% (95% CI: 10.8% to 13.4%; ACEI/ARB), and 2.0% (95% CI: 1.5% to 2.6%; ARNI) were receiving target doses. CONCLUSIONS: In a large, contemporary registry of outpatients with chronic HFrEF eligible for treatment with BBs and ACEI/ARB/ARNI, <20% of patients were receiving target doses, even among those with SBP ≥110 mm Hg.

BACKGROUND: Acute decompensated heart failure accounts for more than 1 million hospitalizations in the United States annually. Whether the initiation of sacubitril-valsartan therapy is safe and effective among patients who are hospitalized for acute decompensated heart failure is unknown. METHODS: We enrolled patients with heart failure with reduced ejection fraction who were hospitalized for acute decompensated heart failure at 129 sites in the United States. After hemodynamic stabilization, patients were randomly assigned to receive sacubitril-valsartan (target dose, 97 mg of sacubitril with 103 mg of valsartan twice daily) or enalapril (target dose, 10 mg twice daily). The primary efficacy outcome was the time-averaged proportional change in the N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentration from baseline through weeks 4 and 8. Key safety outcomes were the rates of worsening renal function, hyperkalemia, symptomatic hypotension, and angioedema. RESULTS: Of the 881 patients who underwent randomization, 440 were assigned to receive sacubitril-valsartan and 441 to receive enalapril. The time-averaged reduction in the NT-proBNP concentration was significantly greater in the sacubitril-valsartan group than in the enalapril group; the ratio of the geometric mean of values obtained at weeks 4 and 8 to the baseline value was 0.53 in the sacubitril-valsartan group as compared with 0.75 in the enalapril group (percent change, -46.7% vs. -25.3%; ratio of change with sacubitril-valsartan vs. enalapril, 0.71; 95% confidence interval [CI], 0.63 to 0.81; P<0.001). The greater reduction in the NT-proBNP concentration with sacubitril-valsartan than with enalapril was evident as early as week 1 (ratio of change, 0.76; 95% CI, 0.69 to 0.85). The rates of worsening renal function, hyperkalemia, symptomatic hypotension, and angioedema did not differ significantly between the two groups. CONCLUSIONS: Among patients with heart failure with reduced ejection fraction who were hospitalized for acute decompensated heart failure, the initiation of sacubitril-valsartan therapy led to a greater reduction in the NT-proBNP concentration than enalapril therapy. Rates of worsening renal function, hyperkalemia, symptomatic hypotension, and angioedema did not differ significantly between the two groups.

Background Current guidelines recommend sacubitril/valsartan for patients with heart failure with reduced ejection fraction, but the rate of adoption in the United States has been slow. Methods and Results Using data from CHAMP-HF (Change the Management of Patients With Heart Failure), we described current sacubitril/valsartan use and identified patient, provider, and practice characteristics associated with its use. We considered patients to be on sacubitril/valsartan if they were prescribed it before enrollment or initiated on it at the baseline visit. We excluded patients with a contraindication to sacubitril/valsartan and practices with <10 patients enrolled. Of 4216 patients from 121 sites, 616 (15%) were prescribed sacubitril/valsartan, 2506 (59%) an angiotensin-converting enzyme (ACE) inhibitor/angiotensin receptor blocker (ARB), and 1094 (26%) neither. Patients prescribed sacubitril/valsartan were younger (63 years versus 66 years ACE inhibitor/ARB versus 69 years neither, P<0.001), less likely to have chronic kidney disease (15% versus 17% ACE inhibitor/ARB versus 30% neither, P<0.001), more likely to have cardiac resynchronization therapy (12% versus 7% ACE inhibitor/ARB versus 7% neither, P<0.001), and had lower ejection fraction (27% versus 30% ACE inhibitor/ARB versus 30% neither, P<0.001). Larger practices, based on number of cardiologists and advanced practice providers, were associated with the highest sacubitril/valsartan use. After multivariable adjustment, the number of advanced practice providers was associated with sacubitril/valsartan use (adjusted odds ratio,1.08; 95% CI, 1.03-1.14). Conclusions Despite current guideline recommendations, adoption of sacubitril/valsartan remains low. Provider and practice characteristics associated with sacubitril/valsartan use were related to general practice size and were not associated with practice characteristics specific for heart failure. Further research is needed to identify strategies for effective quality improvement interventions in chronic heart failure with reduced ejection fraction.

BACKGROUND: Guidelines strongly recommend patients with heart failure with reduced ejection fraction (HFrEF) be treated with multiple medications proven to improve clinical outcomes, as tolerated. The degree to which gaps in medication use and dosing persist in contemporary outpatient practice is unclear. OBJECTIVES: This study sought to characterize patterns and factors associated with use and dose of HFrEF medications in current practice. METHODS: The CHAMP-HF (Change the Management of Patients with Heart Failure) registry included outpatients in the United States with chronic HFrEF receiving at least 1 oral medication for management of HF. Patients were characterized by baseline use and dose of angiotensin-converting enzyme inhibitor (ACEI)/angiotensin II receptor blocker (ARB), angiotensin receptor neprilysin inhibitor (ARNI), beta-blocker, and mineralocorticoid receptor antagonist (MRA). Patient-level factors associated with medication use were examined. RESULTS: Overall, 3,518 patients from 150 primary care and cardiology practices were included. Mean age was 66 ± 13 years, 29% were female, and mean EF was 29 ± 8%. Among eligible patients, 27%, 33%, and 67% were not prescribed ACEI/ARB/ARNI, beta-blocker, and MRA therapy, respectively. When medications were prescribed, few patients were receiving target doses of ACEI/ARB (17%), ARNI (14%), and beta-blocker (28%), whereas most patients were receiving target doses of MRA therapy (77%). Among patients eligible for all classes of medication, 1% were simultaneously receiving target doses of ACE/ARB/ARNI, beta-blocker, and MRA. In adjusted models, older age, lower blood pressure, more severe functional class, renal insufficiency, and recent HF hospitalization generally favored lower medication utilization or dose. Social and economic characteristics were not independently associated with medication use or dose. CONCLUSIONS: In this contemporary outpatient HFrEF registry, significant gaps in use and dose of guideline-directed medical therapy remain. Multiple clinical factors were associated with medication use and dose prescribed. Strategies to improve guideline-directed use of HFrEF medications remain urgently needed, and these findings may inform targeted approaches to optimize outpatient medical therapy.

BACKGROUND: The US Food and Drug Administration approved sacubitril/valsartan for patients with chronic heart failure (HF) with reduced ejection fraction in 2015 on the basis of the results of the PARADIGM-HF (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) trial. There are limited data assessing the generalizability of PARADIGM-HF trial participants to a broader population of patients with HF with reduced ejection fraction routinely encountered in outpatient clinical practice. METHODS AND RESULTS: We compared the baseline characteristics of patients in the PARADIGM-HF trial with those in the CHAMP-HF (Change the Management of Patients With Heart Failure) study a large US outpatient registry of patients with HF with reduced ejection fraction. Patients in the PARADIGM-HF trial (n=8442) were similar to those in the CHAMP-HF registry (n=3497) in terms of age (mean, 64 versus 66 years), sex (22% versus 29% women), New York Heart Association class III to IV (25% versus 32%), systolic blood pressure (mean, 121 versus 121 mm Hg), left ventricular ejection fraction (mean, 29% versus 29%), and other key baseline characteristics. The median (25th-75th percentile) Meta-Analysis Global Group in Chronic Heart Failure risk scores were similar for the 2 studies (20 [16-24] versus 22 [8-27]). Despite this, only 13% of patients in the CHAMP-HF registry were prescribed sacubitril/valsartan at baseline. CONCLUSIONS: These data suggest participants randomized in the PARADIGM-HF trial have similar baseline characteristics to those encountered in routine outpatient clinical practice, but there is a substantial lag in the adoption of sacubitril/valsartan for patients with chronic HF with reduced ejection fraction.

OBJECTIVES: This study sought to describe the health status of outpatients with heart failure and reduced ejection fraction (HFrEF) by sex, race/ethnicity, and socioeconomic status (SES). BACKGROUND: Although a primary goal in treating patients with HFrEF is to optimize health status, whether disparities by sex, race/ethnicity, and SES exist is unknown. METHODS: In the CHAMP-HF (Change the Management of Patients with Heart Failure) registry, the associations among sex, race, and SES and health status, as measured by the Kansas City Cardiomyopathy Questionnaire-overall summary (KCCQ-os) score (range 0 to 100; higher scores indicate better health status) was compared among 3,494 patients from 140 U.S. clinics. SES was categorized by total household income. Hierarchical multivariate linear regression estimated differences in KCCQ-os score after adjusting for 31 patient characteristics and 10 medications. RESULTS: Overall mean KCCQ-os scores were 64.2 ± 24.0 but lower for women (29% of sample; 60.3 ± 24.0 vs. 65.9 ± 24.0, respectively; p < 0.001), for blacks (60.5 ± 25.0 vs. 64.9 ± 23.0, respectively; p < 0.001), for Hispanics (59.1 ± 21.0 vs. 64.9 ± 23.0, respectively; p < 0.001), and for those with the lowest income (<$25,000; mean: 57.1 vs. 63.1 to 74.7 for other income categories; p < 0.001). Fully adjusted KCCQ-os scores were 2.2 points lower for women (95% confidence interval [CI]: -3.8 to -0.6; p = 0.007), no different for blacks (p = 0.74), 4.0 points lower for Hispanics (95% CI: -6.6 to -1.3; p = 0.003), and lowest in the poorest patients (4.7 points lower than those with the highest income (95% CI: 0.1 to 9.2; p = 0.045; p for trend = 0.003). CONCLUSIONS: Among outpatients with HFrEF, women, blacks, Hispanics, and poorer patients had worse health status, which remained significant for women, Hispanics, and poorer patients in fully adjusted analyses. This suggests an opportunity to further optimize treatment to reduce these observed disparities.

BACKGROUND: Sacubitril/valsartan is an angiotensin receptor-neprilysin inhibitor indicated for the treatment of patients with chronic heart failure (HF) with reduced ejection fraction; however, its mechanism of benefit remains unclear. Biomarkers that are linked to ventricular remodeling, myocardial injury, and fibrosis may provide mechanistic insight and important clinical guidance regarding sacubitril/valsartan use. METHODS: This 52-week, multicenter, open-label, single-arm study is designed to (1) correlate biomarker changes with cardiac remodeling parameters, cardiovascular outcomes, and patient-reported outcome data and (2) determine short- and long-term changes in concentrations of biomarkers related to potential mechanisms of action and effects of sacubitril/valsartan therapy. Approximately 830 patients with HF with reduced ejection fraction will be initiated and titrated on sacubitril/valsartan according to United States prescribing information. Primary efficacy end points include the changes in N-terminal pro-B-type natriuretic peptide concentrations and cardiac remodeling from baseline to 1 year. Secondary end points include changes in concentrations of N-terminal pro-B-type natriuretic peptide and remodeling to 6 months, and changes in patient-reported outcomes using the Kansas City Cardiomyopathy Questionnaire-23 from baseline to 1 year. In addition, several other relevant biomarkers will be measured. Biomarker changes relative to the number of cardiovascular events in 12 months will also be assessed as exploratory end points. CONCLUSIONS: Results from the Prospective Study of Biomarkers, Symptom Improvement, and Ventricular Remodeling During Sacubitril/Valsartan Therapy for Heart Failure (PROVE-HF) will help establish a mechanistic understanding of angiotensin receptor-neprilysin inhibitor therapeutic benefits and provide clinicians with clarity on how to interpret information on biomarkers during treatment (PROVE-HF ClinicalTrials.gov identifier: NCT02887183).

BACKGROUND: Although a key treatment goal for patients with heart failure with reduced ejection fraction is to optimize their health status (their symptoms, function, and quality of life), the variability across outpatient practices in achieving this goal is unknown. METHODS AND RESULTS: In the CHAMP-HF (Change the Management of Patients With Heart Failure) registry, associations between baseline practice characteristics and Kansas City Cardiomyopathy Questionnaire (KCCQ) Overall Summary (OS) and Symptom Frequency (SF) scores were assessed in 3494 patients across 140 US practices using hierarchical regression after accounting for 23 patient and 11 treatment characteristics. We then calculated an adjusted median odds ratio to quantify the average difference in likelihood that a patient would have excellent (KCCQ-OS, ≥75) health status or minimal (monthly or fewer) symptoms (KCCQ-SF, ≥75) when treated at one practice versus another, at random. The mean (±SD) KCCQ-OS and KCCQ-SF were 64.2±24 and 68.9±25.6, with 40% (n=1380) and 50% (n=1760) having KCCQ scores ≥75, respectively. The adjusted median odds ratio across practices, for KCCQ-OS ≥75, was 1.70 (95% confidence interval, 1.54-1.99; P<0.001) indicating a median 70% higher odds of a patient having good-to-excellent health status when treated at one random practice versus another. In regard to KCCQ-SF, the adjusted median odds ratio for KCCQ-SF ≥75 was 1.54 (95% confidence interval, 1.41-1.76; P=0.001). CONCLUSIONS: In a large, contemporary registry of outpatients with chronic heart failure with reduced ejection fraction, we observed significant practice-level variability in patients' health status. Quantifying patients' health status as a measure of quality should be explored as a foundation for improving care. CLINICAL TRIAL REGISTRATION: URL: https://www.centerwatch.com.

OBJECTIVE: The objective is to assess the safety, tolerability, and efficacy of sacubitril/valsartan compared with enalapril in patients with heart failure (HF) with a reduced ejection fraction (EF) stabilized during hospitalization for acute decompensated HF. BACKGROUND: Sacubitril/valsartan, a first-in-class angiotensin receptor-neprilysin inhibitor, improves survival among ambulatory HF patients with a reduced EF. However, there is very limited experience with the in-hospital initiation of sacubitril/valsartan in patients who have been stabilized following hospitalization for acute decompensated HF. METHODS: PIONEER-HF is a 12-week, prospective, multicenter, double-blind, randomized controlled trial enrolling a planned 882 patients at more than 100 participating sites in the United States. Medically stable patients >18 years of age with an EF <40% and an amino terminal-pro b-type natriuretic peptide >1600 pg/mL or b-type natriuretic peptide >400 pg/mL are eligible for participation no earlier than 24 hours and up to 10 days from initial presentation while still hospitalized. Patients are randomly assigned 1:1 to in-hospital initiation of sacubitril/valsartan titrated to 97/103 mg by mouth twice daily versus enalapril titrated to 10 mg by mouth twice daily for 8 weeks. All patients receive open-label treatment with sacubitril/valsartan for the remaining 4 weeks of the study. The primary efficacy end point is the time-averaged proportional change in amino terminal-pro b-type natriuretic peptide from baseline through weeks 4 and 8. Secondary and exploratory end points include serum and urinary biomarkers as well as clinical outcomes. Safety end points include the incidence of angioedema, hypotension, renal insufficiency, and hyperkalemia. CONCLUSION: The PIONEER-HF trial will inform clinical practice by providing evidence on the safety, tolerability, and efficacy of in-hospital initiation of sacubitril/valsartan among patients who have been stabilized following an admission for acute decompensated HF with a reduced EF.
