Spironolactone start study for heart failure with preserved pumping
This trial tests whether starting spironolactone helps people with heart failure symptoms when the heart pumps “preserved” (not severely reduced). Participants are assigned to start spironolactone or usual care so researchers can see if it improves outcomes.
Alexander City, AlabamaAges 50–99 - NCT07693049Recruiting
Exercise training for heart failure with preserved pumping ability
This trial tests whether high-intensity interval training can improve heart function and fitness in people with a type of heart failure where the heart pumps normally but doesn't fill properly. You will do supervised exercise sessions to see if it helps you feel better and be more active.
BeijingAges 35–70 - NCT07634640RecruitingEarly Phase 1
Testing an Inflammation Treatment for Heart Failure
This early-stage trial tests a new approach to treat heart failure with preserved ejection fraction (HFpEF)—a type of heart failure where the heart's pumping strength is normal, but it doesn't relax properly. Researchers believe inflammation plays a role and want to see if targeting it can help patients feel better and function more easily.
Gainesville, FloridaAges 18–85 - NCT06249945RecruitingPhase 4
Empagliflozin for heart failure with preserved ejection fraction and dialysis
This trial tests whether a medicine called empagliflozin (used for diabetes and heart failure) can help people with both heart failure (with preserved pumping ability) and end-stage kidney disease who are on dialysis. The study looks at how the drug affects heart function and overall well-being.
HsinchuAges 20 years+ - NCT07560436RecruitingPhase 2
Stents for Heart Failure With Normal Pumping
This trial tests whether placing stents in coronary arteries helps patients with heart failure who still have a strong-pumping heart. The study aims to see if improving blood flow to the heart reduces symptoms and improves quality of life.
