Can a common heart drug improve how the heart relaxes?
NCT ID NCT07157527
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at whether the drug sacubitril/valsartan (Entresto) can improve the heart's ability to relax in people with heart failure and reduced pumping strength. Researchers will use ultrasound to measure changes after six months of treatment. The study involves 70 adults from two heart centers in Egypt.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sacubitril/valsartan (Entresto)
- What this could lead to
- If successful, this could show that sacubitril/valsartan improves heart relaxation in patients with heart failure and reduced pumping ability, potentially guiding better treatment.
- What could go wrong
- This is a small, early-stage observational study with only 70 participants. It may not prove long-term benefits, and results may not apply to all heart failure patients.

Who is studied
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.
