Angiotensin Receptor Neprilysin Inhibition and Cardiovascular Outcomes Across the Kidney Function Spectrum: The PARAGON-HF Trial.

JACC Heart Fail

November 2024

Harvard Medical School, Boston, Massachusetts, USA; Cardiovascular Division, Department of Medicine, Brigham and Women's Hospital, Boston, Massachusetts, USA.

Background: Lower estimated glomerular filtration rate (eGFR) may be one of the major reasons for hesitation or failure to initiate potentially beneficial therapies in patients with heart failure (HF).

Objectives: This study sought to assess if the effects of sacubitril/valsartan (vs valsartan) on cardiovascular outcomes differ according to baseline kidney function in patients with HF with preserved ejection fraction.

Methods: The PARAGON-HF (Prospective Comparison of ARNI with ARB Global Outcomes in HF with Preserved Ejection Fraction) trial was global clinical trial of 4,796 patients with chronic HF and left ventricular ejection fraction (LVEF) ≥45% randomly assigned to sacubitril/valsartan or valsartan.

Article Synopsis
  • Obesity is linked to heart failure with preserved ejection fraction (HFpEF), characterized by changes in heart structure and increased epicardial adipose tissue (EAT), which can lead to negative health outcomes.
  • The SUMMIT trial's CMR substudy aimed to assess how tirzepatide influenced cardiac structure and function in patients with obesity-related HFpEF, focusing on its potential to lower left ventricular (LV) mass and EAT.
  • Results showed that tirzepatide treatment significantly reduced LV mass by 11 g and paracardiac adipose tissue by 45 ml compared to placebo, with changes in LV mass correlated to body weight and other cardiac measures.

Centrally adjudicated vs. investigator-reported outcomes in randomized heart failure trials.

Eur Heart J

December 2024

Development, Novartis Pharma AG, Forum 1, Novartis Campus, CH-4056 Basel, Switzerland.

Article Synopsis
  • Heart failure events in cardiovascular trials are often evaluated through centralized review, but its impact on treatment effect accuracy (in terms of hazard ratios) is uncertain.
  • In a study of seven trials, positive adjudication rates for heart failure events were generally lower than for cardiovascular deaths, affecting subsequent mortality risk.
  • Overall, while central adjudication showed some correlation between event types, it didn’t significantly change the results, suggesting that the need for centralized review should be tailored to each trial's objectives.

Consequences of Discontinuing Long-Term Drug Treatment in Patients With Heart Failure and Reduced Ejection Fraction.

J Am Coll Cardiol

November 2024

Baylor Heart and Vascular Institute, Dallas, Texas, USA; Imperial College London, London, United Kingdom. Electronic address:

There is uncertainty regarding the clinical effects of discontinuation of drugs for heart failure after long-term use. The withdrawal of long-term treatment can follow 1 of 4 distinct patterns: 1) loss of on-treatment effect with no observed changes following discontinuation (eg, prazosin); 2) attenuation or loss of on-treatment effect with rebound clinical worsening following discontinuation (eg, nitroprusside); 3) persistence of deleterious on-treatment effect followed by clinical worsening after discontinuation (eg, milrinone and flosequinan); and 4) persistence of favorable on-treatment effect followed by clinical worsening after discontinuation (eg, digoxin and sodium-glucose cotransporter 2 inhibitors). Persuasive evidence for persistence of efficacy has been demonstrated for the use of digoxin, diuretic agents, sodium-glucose cotransporter 2 inhibitors, and (to a limited extent) for angiotensin-converting enzyme inhibitors.

Article Synopsis
  • SGLT2 inhibitors, like empagliflozin, are shown to improve outcomes for heart failure patients and reduce uric acid levels, with a focus on those having heart failure with preserved ejection fraction (HFpEF).
  • In a study of patients receiving empagliflozin, about 49% had elevated uric acid levels, which were linked to worse heart failure severity and higher risk of severe outcomes like hospitalization.
  • Empagliflozin significantly lowered uric acid levels early on and reduced related clinical events by 38%, with its effectiveness in improving heart failure outcomes not impacted by initial uric acid levels.

Aims: Resting heart rate (HR) is a strong risk marker in patients with heart failure (HF), but the clinical implications of visit-to-visit changes in HR (ΔHR) are less well established. We aimed to explore the association between ΔHR and subsequent outcomes in a pooled dataset of two well-characterized cohorts of patients with HF across the full range of left ventricular ejection fraction (LVEF).

Methods And Results: PARADIGM-HF and PARAGON-HF were randomized trials testing sacubitril/valsartan versus enalapril or valsartan, respectively, in patients with HF and LVEF ≤40% (PARADIGM-HF) or LVEF ≥45% (PARAGON-HF).

Background: Cognitive impairment is common in patients with heart failure and preserved ejection fraction but its clinical correlates and prognostic associations are poorly understood.

Methods: We analyzed cognitive function, using the Mini-Mental State Examination (MMSE), in patients with heart failure and preserved ejection fraction enrolled in a prespecified substudy of the PARAGON-HF trial (Prospective Comparison of Angiotensin Receptor Neprilysin Inhibitor With Angiotensin Receptor Blocker Global Outcomes in Heart Failure With Preserved Ejection Fraction). Logistic regression analyses were performed to determine the variables associated with lower MMSE scores at baseline and postbaseline decline in MMSE scores at 48 weeks.

Race in Heart Failure: A Pooled Participant-Level Analysis of the Global PARADIGM-HF and PARAGON-HF Trials.

JACC Heart Fail

August 2024

Division of Cardiovascular Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA. Electronic address:

Article Synopsis
  • - The study investigated how race influences the effects of the heart failure treatment sacubitril/valsartan, comparing its safety and efficacy among White, Asian, and Black patients based on data from two large clinical trials (PARADIGM-HF and PARAGON-HF).
  • - Results showed that Black and Asian patients had a higher risk of heart failure hospitalization or cardiovascular death compared to White patients, even though the treatment was effective for all racial groups, with no significant difference in efficacy observed across races.
  • - Severe angioedema (swelling) was more common in Black patients receiving sacubitril/valsartan compared to those on alternative treatments, highlighting potential racial disparities in treatment response and safety.

Aims: Glucagon-like peptide-1 receptor agonists reduce major adverse cardiovascular events (MACE) and cardiovascular mortality in people with type 2 diabetes (T2D). However, previous studies suggest the effects on heart failure outcomes vary according to left ventricular ejection fraction (LVEF). We aimed to evaluate the effects of exenatide on cardiovascular events according to LVEF in people with T2D.

Article Synopsis
  • The study investigated the impact of hypotension on heart failure outcomes using data from the PARADIGM-HF trial, focusing on the differences between asymptomatic and symptomatic hypotension.
  • Out of 8,399 patients, 16% had only asymptomatic hypotension, while 11.1% experienced symptomatic hypotension, with those having symptomatic hypotension being older and having more cardiovascular issues.
  • Despite the risks associated with either type of hypotension, the heart failure medication sacubitril/valsartan showed consistent effectiveness and safety compared to enalapril across all patient groups.

Article Synopsis
  • In randomized trials, deaths that are unrelated to the primary outcome being studied are classified as competing risks, and traditional analysis methods may inaccurately treat these deaths like censored data.
  • The Fine and Gray model, often used for analyzing competing risks, can be misapplied and potentially deliver misleading results.
  • The authors suggest a new multiple imputation approach that better accounts for the risk factors associated with both death and the outcomes of interest, and they provide recommendations for future trials based on their findings from three cardiovascular studies.

Aims: Renin-angiotensin system inhibitors (RASi) have been shown to lower haemoglobin levels, potentially related to reductions in erythropoietin levels and haematopoiesis. We examined whether sacubitril/valsartan might attenuate this effect of RASi alone on incident anaemia in patients with heart failure (HF) with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF).

Methods And Results: PARAGON-HF was a global, multicentre randomized clinical trial of sacubitril/valsartan versus the RASi valsartan in patients with HF and left ventricular ejection fraction ≥45%.

Background: Sodium-glucose cotransporter 2 (SGLT2) inhibitors exert a distinctive pattern of direct biological effects on the heart and kidney under experimental conditions, but the meaningfulness of these signatures for patients with heart failure has not been fully defined.

Objectives: We performed the first mechanistic validation study of large-scale proteomics in a double-blind randomized trial of any treatment in patients with heart failure.

Methods: In a discovery cohort from the EMPEROR (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure and Reduced Ejection Fraction) program, we studied the effect of randomized treatment with placebo or empagliflozin on 1,283 circulating proteins in 1,134 patients with heart failure with a reduced or preserved ejection fraction.

Background: Kidney outcomes have been variably defined using nonstandardized composite end points in key heart failure trials, thus introducing complexity in their interpretation and cross-trial comparability. We examined the effects of steroidal mineralocorticoid receptor antagonists, the angiotensin receptor-neprilysin inhibitor sacubitril/valsartan, and SGLT2 (sodium-glucose cotransporter-2) inhibitors on composite kidney end points using uniform definitions in 6 contemporary heart failure trials.

Methods: Individual participant-level data from trials of steroidal mineralocorticoid receptor antagonists (EMPHASIS-HF [Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure], TOPCAT [Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist] Americas), angiotensin receptor-neprilysin inhibitor (PARADIGM-HF [Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure], PARAGON-HF [Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor With Angiotensin-Receptor Blockers Global Outcomes in HF With Preserved Ejection Fraction]), and SGLT2 inhibitors (DAPA-HF [Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure], DELIVER [Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure]) were included.

Article Synopsis
  • The study aimed to investigate the impact of beta-blocker (BB) use on clinical outcomes in patients with heart failure, specifically those with mildly reduced and preserved ejection fraction, using a large observational analysis.
  • A total of 16,951 patients were analyzed, with 75.6% receiving BB treatment; results showed that while unadjusted outcomes were similar for BB users and non-users, adjusted outcomes indicated that BB users had better outcomes, especially in those with atrial fibrillation.
  • The conclusions suggest that BB treatment does not correlate with worse heart failure outcomes, even after considering various other health factors.

Article Synopsis
  • The study aims to understand heart failure (HF) characteristics and outcomes specifically in octogenarians (people aged 80 and older), as this age group is often underrepresented in research despite higher HF prevalence.
  • Analysis of data from eight randomized trials revealed that octogenarians with different types of HF (HFrEF, HFmrEF, HFpEF) tended to be more female and had more health complications, worse health status, and higher rates of hospitalization and mortality compared to younger patients.
  • The findings indicate that octogenarians receive less treatment based on guidelines, particularly certain medications, despite their poorer health and worse outcomes, suggesting a need for better management in this age group.

Article Synopsis
  • This study compares the prognostic value of different body measurement indices, like BMI and waist-to-height ratio, in predicting mortality in patients with non-ischaemic heart failure with reduced ejection fraction (HFrEF).
  • It finds that higher BMI is linked to increased risks of all-cause and cardiovascular death, particularly in patients with a BMI of 35 or more.
  • The research suggests that greater waist-to-height ratios also indicate higher mortality risk, highlighting the importance of fat location and distribution beyond just body weight.
