Stopping and reversing heart scarring in HFpEF
Preventing and Reversing Interstitial Fibrosis in HFpEF
This project tests ways to prevent and reverse the scarring that stiffens the heart in people with heart failure with preserved ejection fraction (HFpEF).

What this research studies
Researchers are creating animal models that more closely match typical HFpEF patients—older adults often with obesity, diabetes, or controlled high blood pressure—in order to study why the heart becomes stiff. They will study inflammation, coronary microvascular function, and the cellular pathways that drive interstitial fibrosis. The team will use these models to test interventions that might prevent or reverse the scarring process and restore healthier heart function. Findings are intended to point to treatments that could later be tested in people.
Who could benefit from this research
Good fit: Adults diagnosed with HFpEF (preserved ejection fraction), especially older patients with common comorbidities like obesity, diabetes, or controlled hypertension, would be the eventual candidates for therapies developed from this work.
Not a fit: People with heart failure due to reduced ejection fraction or those whose symptoms are caused by non-cardiac conditions are unlikely to benefit from findings targeted to HFpEF.
Why it matters
Potential benefit: If successful, this work could identify therapies that reduce heart scarring and improve symptoms and outcomes for people with HFpEF.
How similar studies have performed: Previous animal models have relied on severe, uncontrolled hypertension and have had limited success translating to typical HFpEF patients, so this work follows a relatively novel, more patient-representative approach.
