Abstract 4364889: Semiquantitative urine dipstick protein assessments predict clinical outcomes in patients with heart failure and reduced ejection fraction: Insights from the GALACTIC-HF trial

Conference Circulation · November 4, 2025 Background: Although it is known that increased urinary protein excretion is predictive of both end-stage kidney disease and cardiovascular (CV) outcomes, laboratory quantification of ... Full text Cite

Abstract 4365493: Lactate dehydrogenase and clinical outcomes in patients with heart failure and reduced ejection fraction: Insights from the GALACTIC-HF trial

Conference Circulation · November 4, 2025 Background: Lactate dehydrogenase (LDH) is a cytoplasmic enzyme found in most cells that catalyses the forward and backwards conversion of pyruvate to lactate. Tissue LDH concentration ... Full text Cite

Abstract 4144501: Effect of the Cardiac Myosin Activator Omecamtiv Mecarbil on Risk of Ventricular Arrhythmias in Heart Failure with Reduced Ejection Fraction: the GALACTIC-HF Trial

Conference Circulation · November 12, 2024 Introduction: The selective cardiac myosin activator, omecamtiv mecarbil (OM), has been shown to benefit individuals with HFrEF but the clinical experience of cardiac myosin activators and incidence o ... Full text Cite

Abstract 4139790: Efficacy and Safety of Omecamtiv Mecarbil in Heart Failure with Reduced Ejection Fraction According to Age: the GALACTIC-HF Trial

Conference Circulation · November 12, 2024 Background: Older age is associated with a high prevalence of comorbidities and worse cardiovascular (CV) outcomes in patients with heart failure with reduced ejection fraction (HFrEF). Omecamtiv meca ... Full text Cite

Electronic health record characterization and outcomes of heart failure with preserved ejection fraction.

Conference Am Heart J · September 2023 BACKGROUND: Electronic health record (EHR)-based identification of heart failure with preserved ejection fraction (HFpEF) in the clinical setting may facilitate screening for clinical trials by improving the understanding of its epidemiology and outcomes; ...

Accelerometer-Measured Daily Activity in Heart Failure With Preserved Ejection Fraction: Clinical Correlates and Association With Standard Heart Failure Severity Indices.

Conference Circ Heart Fail · June 2017 BACKGROUND: Daily physical activity assessed by accelerometers represents a novel method to assess the impact of interventions on heart failure (HF) patients' functional status. We hypothesized that daily activity varies by patient characteristics and corr ... Full text Link to item Cite

A Multi-Marker Approach for Risk Stratification in Patients With Chronic Heart Failure: Insights From the HF-ACTION Trial
