Heart Failure Breakthrough: How This Treatment Boasts a 9-Point Surge in Quality of Life!
New Study Reveals: Better Heart Function DIRECTLY Improves Daily Life for Heart Failure Patients If you or a loved one struggles with heart failure (HFrEF), you know how debilitating fatigue, breathlessness, and poor stamina can be. But what if your treatment could not just prolong life—but actually make you FEEL better?

A groundbreaking study from the European Journal of Heart Failure (Lee et al., 2025) reveals which heart improvements matter most for quality of life—and the results could change how doctors treat HFrEF forever.
The Key Finding You Need to Know
"Patients saw a 9-point jump in their quality-of-life score—simply from better heart relaxation and reduced pressure in the heart!"
This isn’t just about living longer—it’s about living BETTER.
What Did the Study Show?
Researchers followed 406 HFrEF patients (average age 67) and tracked:
✔ Heart structure & function (via advanced echocardiography)
✔ Quality of life (using the KCCQ-12 questionnaire)
Two treatments were compared:
1️⃣ Sacubitril-valsartan (a top-tier HFrEF drug)
2️⃣ Enalapril (an older ACE inhibitor)
After 24 weeks, the results were stunning…
The 3 Biggest Discoveries
Sacubitril-Valsartan OUTPERFORMED Enalapril in Boosting Daily Life
Patients on sacubitril-valsartan reported an 11-point boost in quality of life.
Those who started on enalapril first only improved by 6 points.
Conclusion? Starting the right drug EARLIER makes a HUGE difference.
It’s NOT Just About Pumping Strength—It’s About Heart “Relaxation”
Most heart failure treatments focus on ejection fraction (EF)—how well the heart pumps. But this study found:
Better diastolic function (heart relaxation) = BIGGER quality-of-life gains
↑ Mitral e′ velocity → +2.5 points in life quality
↓ E/e′ ratio (lower heart pressure) → +3.2 points
EF improvement? Surprisingly, NOT linked to feeling better!
Shrinking the Left Atrium = Fewer Symptoms
A smaller left atrial volume index (LAVi) meant +2.0 points in well-being.
Why? The left atrium stores blood—if it’s enlarged, pressure builds up, causing fatigue & breathlessness.
What This Means for YOU
If you’re on enalapril, ask your doctor about switching to sacubitril-valsartan.
Demand echocardiograms that check diastolic function (E/e′, LAVi)—not just EF.
Early treatment matters! The sooner you optimize therapy, the better you’ll feel.
The Bottom Line
This study proves: Heart failure treatment isn’t just about survival—it’s about THRIVING.
"We now know that improving how the heart relaxes and reducing pressure can make patients feel dramatically better—sometimes within weeks." — Lead Researcher
