Recruiting studies
- NCT06526988Recruiting
Heart failure medication optimization study for clinicians and patients
This study tests tools to help doctors and patients work together to start or adjust heart failure medicines. You may qualify if your heart's pumping strength is low and you are missing certain recommended medications.

Can you stop beta-blockers after heart failure recovery?
This trial tests whether people whose heart function has returned to normal after heart failure can safely stop taking beta-blockers. It aims to see if staying on the medication is still needed or if stopping is just as safe.
Paris, IDFAges 18 years+ - NCT05029570Recruiting
Heart rate control for permanent atrial fibrillation and heart failure
This trial studies whether a strategy to regularize (control) heart rate can improve outcomes in people who have permanent atrial fibrillation and heart failure. It focuses on people with recent heart-failure hospitalization and checks several heart, kidney, and health-condition limits to keep the study safe.
Madrid, MadridAges 18 years+ - NCT06423599RecruitingPhase 2/Phase 3

This trial tests a pill called midodrine to see if it can safely raise blood pressure in people with heart failure and low blood pressure. It may help you feel better and avoid needing IV treatments while in the hospital.
Ottawa, OntarioAges 18 years+ - NCT06409585Recruiting
Heart muscle disease imaging study for scarring
This study uses advanced imaging (PET/MR or PET/CT) to look at scarring (fibrosis) in the heart muscle. It is for people with various heart muscle diseases, including heart failure with preserved pumping, thickened heart muscle, high blood pressure-related heart damage, heart inflammation, and others.
Edinburgh, ScotlandAges 30–90 - NCT06361524Enrolling by invitation
Gut bacteria study in chronic heart failure
This study looks at the bacteria in your gut (your 'gut microbiome') and how it relates to chronic heart failure. It may help doctors understand why some people with heart failure do better than others and could lead to better treatments in the future.
Stanford, CaliforniaAges 18–75 - NCT06299436Recruiting
Heart muscle function testing in right heart failure
This trial studies how the right side of the heart works in people with heart failure. It uses special monitoring to understand muscle function and may help doctors find better ways to treat right heart failure.
Baltimore, MarylandAges 18–90 - NCT06299176Enrolling by invitationPhase 1
Whole-heart radiation therapy for advanced heart failure
This trial tests if a low dose of radiation to the whole heart can help people with very advanced heart failure. It is for people who have severe symptoms despite maximum medications and are not candidates for a heart pump or transplant.
Montreal, QuebecAges 65 years+ - NCT06258447Recruiting
CardiAMP bone marrow cell therapy for heart failure
This trial tests a new treatment using your own bone marrow cells to help your heart pump better. It's for people with heart failure after a heart attack whose heart function is moderately reduced.
Clearwater, FloridaAges 21–90 - NCT06241430Recruiting
CardioClip study: testing a new valve repair for leaky heart valve
This study tests a new clip procedure (CardioClip) to repair a leaky mitral valve in people with heart failure. It aims to see if the clip can improve symptoms and heart function.
New York, New YorkAges 18–90 - NCT06229678RecruitingEarly Phase 1
Ketones and diabetes drug for heart failure with weak pump
This clinical trial looks at whether adding a special diet supplement (ketones) to an SGLT2 inhibitor diabetes drug improves heart function and symptoms in people who have both type 2 diabetes and heart failure with a weakened heart muscle.
San Antonio, TexasAges 18–70 - NCT05650658Recruiting
Compare two heart pacing options in people with weak heart function
This trial compares two types of “left-side” heart pacing to see which one works better in people with weak heart pumping. It may help guide the best pacing choice for improving heart function and symptoms.
Gilbert, ArizonaAges 18 years+ - NCT06148935Recruiting
Study of vericiguat in Korean heart failure patients
This study looks at how well Verquvo (vericiguat) works in daily life for Korean adults with chronic heart failure and a weak heart pump. It’s for people whose heart failure has recently gotten worse and who are starting Verquvo for the first time.
Multiple LocationsAges 19 years+ - NCT06108076RecruitingEarly Phase 1
Oral ketones for heart failure and diabetes
This study tests whether taking a special oral ketone supplement can help people with both heart failure and diabetes. It looks at both short-term and long-term effects on heart function and blood sugar control.
San Antonio, TexasAges 18–80 - NCT06128980RecruitingPhase 2/Phase 3
Stopping heart meds after recovery from fast heartbeat damage
This trial tests if patients whose heart function returned to normal after treating a fast heartbeat can safely stop their heart failure medications. It aims to see if treatment can be withdrawn without the heart problems coming back.
CopenhagenAges 18 years+ - NCT05839067Recruiting
Support program for U.S. veterans living with heart failure
This trial supports U.S. Veterans who have heart failure, to see whether the added support improves health and well-being. You may be able to join if you meet the age, diagnosis, and communication requirements.
Gainesville, FloridaAges 18 years+ - NCT06008197RecruitingPhase 3
A study of finerenone for hospitalized heart failure patients
This trial tests a medication called finerenone to see if it helps people hospitalized for heart failure live longer and have fewer heart-related problems. It may be an option for those with a certain type of heart failure where the heart's pumping strength is mildly reduced or normal.
Birmingham, AlabamaAges 18 years+ - NCT05651919Recruiting
Blood test study to understand diabetic heart weakness
This study measures immune cells from your blood to find markers (biomarkers) that may explain or predict diabetic cardiomyopathy, a type of heart condition linked to diabetes. You may benefit mainly by being closely monitored and contributing to research that could improve future diagnosis or risk tracking.
BronAges 40–85 - NCT05508035RecruitingPhase 3
Testing sacubitril/valsartan vs ramipril for heart failure
This trial compares two blood-pressure and heart-failure medicines: sacubitril/valsartan versus ramipril, to see which improves heart pumping and heart structure over time. It’s aimed at people with ischemic (blocked-artery) heart failure with mid-range ejection fraction and ongoing symptoms.
Krakow, Lesser Poland VoivodeshipAges 18 years+ - NCT05255172Enrolling by invitation
Exercise program for heart failure with preserved or reduced pumping

LundAges 50–90 - NCT05138575RecruitingPhase 2
Testing SGLT2 pill and potassium nitrate for heart failure with preserved EF
This trial studies whether two medicines—an SGLT2 inhibitor and potassium nitrate—can improve symptoms and heart function in people with heart failure with preserved ejection fraction (HFpEF). It focuses on people who still have signs of “stiff” or high filling pressure in the heart despite a normal-ish ejection fraction.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05064709Recruiting
Test device for heart failure symptoms in some patients

Common questions
- Are there clinical trials for heart failure with reduced ejection fraction?
- Yes. Clin2 currently lists 182 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.
