Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: The study enrolls 70 patients characterized by a high prevalence of comorbidities including diabetes mellitus, hypertension, obesity, chronic kidney disease, dyslipidemia, and smoking, reflecting the typical clinical profile of Egyptian HFrEF patients. The median age is younger compared to Western cohorts, with patients presenting advanced heart failure symptoms and poorer functional status. Inclusion criteria require participants to tolerate and comply with ARNI therapy and exclude those with significant mitral valve disease, atrial arrhythmias, pacemakers, or poor echocardiographic windows. Comprehensive demographic and clinical data are collected, including sex, NYHA functional class, baseline medications, and heart failure subclassification. This population thus represents a real-world, high-risk group vulnerable to adverse heart failure outcomes, suitable for studying ARNI's effects on diastolic function and overall cardiac remodeling.

Who may be able to join

  • Diagnosed with HFrEF (LVEF < 35%)
  • Able to tolerate and comply with ARNI therapy
  • Patients on Guideline-Directed Medical Therapy (GDMT) for heart failure

Who cannot join

  • Patients with contraindication to ARNI therapy
  • Patients with poor echocardiographic window
  • Patients non-compliant with medication or follow-up
  • Patients with mitral significant lesion or mitral prosthesis.
  • Patients with atrial arrhythmia or on pacemaker

About this study

Official title: Impact of Sacubitril/Valsartan Therapy on Left Ventricular Diastolic Function in Patients With Heart Failure With Reduced Ejection Fraction (HFrEF): An Echocardiographic Evaluation

This prospective cohort study evaluates the effects of six months of sacubitril/valsartan (ARNI) therapy on left ventricular diastolic function in patients with heart failure with reduced ejection fraction (HFrEF) using transthoracic echocardiography. It aims to correlate echocardiographic parameters with clinical status and systolic function among Egyptian patients treated at two cardiology centers.

Read the detailed description

Heart failure remains a leading global health issue characterized by high morbidity and mortality, with a pronounced burden in Egypt due to younger patient age and prevalent comorbidities such as diabetes and hypertension. This study addresses the impact of ARNI therapy, which is established for improving systolic outcomes, on diastolic function-an underexplored aspect contributing to symptom severity and prognosis in HFrEF.

Conducted at Assiut General Hospital and Mabarra Hospital cardiology departments, the prospective cohort study enrolls adult patients (≥18 years) with HFrEF (LVEF < 35%) eligible for and initiating sacubitril/valsartan therapy. Transthoracic echocardiography assessments are performed at baseline and after six months of treatment, measuring parameters such as E/A ratio, E/e' ratio, left atrial volume index, deceleration time, and tricuspid regurgitation velocity according to ASE/EACVI guidelines.

The study also integrates clinical evaluations (NYHA class, comorbidities), ECG changes, and laboratory data. Statistical analyses include paired tests to compare changes over time, and correlations between echocardiographic and clinical/laboratory variables. Ethical approval was obtained, and patient confidentiality is assured.

This investigation aims to contribute novel insights into ARNI's effect on diastolic function in a high-risk Egyptian cohort, potentially informing optimized therapy and management of symptomatic heart failure beyond current evidence primarily focused on systolic improvements.

Questions about this trial

What is this clinical trial studying?

An observational study of Left Ventricular Diastolic Function, run by Assiut University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 5 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Left Ventricular Diastolic Function (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07157527, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2025.
