Recruiting studies
- NCT07259512RecruitingPhase 4
Ramipril once or twice a day for kidney and heart health

Atrial fibrillation treatment: Ablation vs. medication
This trial compares two ways to treat atrial fibrillation in people with heart failure where the heart's pumping strength is still normal. You'll either get a procedure called ablation to restore normal rhythm or medication to control your heart rate. The goal is to see which approach works better for people like you.
Halifax, Nova ScotiaAges 18 years+ - NCT07385417Recruiting
Early AF treatment for heart failure with preserved pumping function
This study tests using a new electrical pulse treatment for atrial fibrillation (AF) early on, in people who also have a type of heart failure where the heart pumps normally but is stiff. The goal is to see if this treatment helps manage both conditions better.
Frankfurt am MainAges 18–80 - NCT07405944RecruitingPhase 4
Vericiguat and heart function in heart failure patients
This trial tests whether vericiguat can improve heart function in people with stable heart failure and a reduced pumping ability. It may help if you have not needed hospital or IV treatments for worsening heart failure in the last 6 months.
LjubljanaAges 18 years+ - NCT07416279Recruiting

Obesity Surgery Study to Prevent Heart Problems
This study follows people with obesity who are having weight-loss surgery to see if the surgery can help prevent a specific type of heart problem (HFpEF) that sometimes develops in people carrying excess weight. Researchers will track your heart health and metabolism before and after surgery.
Heerlen, LimburgAges 35 years+ - NCT07543562RecruitingPhase 3
Selenium supplement for heart failure patients
This study tests whether taking selenium (a mineral supplement) helps heart failure patients feel better and live longer. Researchers will follow patients over time to see if selenium reduces symptoms and hospital visits.
OsloAges 18 years+ - NCT07601724Recruiting
How fluid buildup affects sleep apnea in heart failure
This study looks at how excess fluid in the body affects sleep apnea (pauses in breathing during sleep) in people hospitalized with heart failure. Researchers will measure sleep apnea before and after treatment to reduce the fluid, which may help doctors better manage both conditions together.
JerusalemAges 18 years+ - NCT07626879Recruiting
Ring Blood Pressure Device Compared to Standard 24-Hour Monitoring
This study tests whether a new ring-shaped blood pressure device works as well as the standard 24-hour ambulatory blood pressure monitor in people with heart failure. If the ring device is accurate, it could offer a simpler, more convenient way to track blood pressure at home.

Study of Finerenone for heart and kidney health in diabetes
This trial tests a medication called Finerenone to see if it can improve heart structure and function in people with both diabetic kidney disease and heart failure. If you have type 2 diabetes, kidney problems, and heart failure with preserved pumping function, this study may explore a new treatment option for you.
TaipeiAges 18 years+ - NCT07283666Enrolling by invitation
Heart care quality program for AFib and heart failure
This trial aims to improve care for people with atrial fibrillation (a type of irregular heartbeat) or heart failure with reduced pumping strength. It focuses on making sure you get the right treatments based on your health history and recent visits to a heart doctor.

Testing ketone supplements for heart failure with preserved ejection fraction (HFpEF)
This study tests whether a special dietary supplement (ketone esters) can improve exercise ability and heart function in people with a type of heart failure where the heart pumps well but is stiff (HFpEF). You might join if you have stable symptoms, an ejection fraction of 50% or higher, and signs of fluid buildup in the heart.

Common questions
- Are there clinical trials for heart failure with reduced ejection fraction?
- Yes. Clin2 currently lists 183 recruiting heart failure with reduced ejection fraction studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a heart failure with reduced ejection fraction trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a heart failure with reduced ejection fraction trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
