Recruiting studies
- NCT05966415RecruitingPhase 2
Endocalyx for heart failure with fluid overload
This Phase 2 study tests Endocalyx to treat people with heart failure who currently show signs of fluid buildup (congestion). If you qualify, you may help researchers see whether this supplement can improve symptoms and heart-failure–related measurements.
Amsterdam, North HollandAges 18–110 - NCT06977477Recruiting
Managing fluid buildup in heart failure patients
This study tests a new way to manage fluid buildup in patients with a specific type of heart failure (HFpEF) who are in the hospital. It aims to improve how doctors remove excess fluid and help you feel better.
Magdeburg, Saxony-AnhaltAges 18 years+ - NCT05802849RecruitingPhase 4
Oral acetazolamide for worsening heart failure
This trial tests whether taking acetazolamide by mouth can help prevent or improve worsening (decompensation) of heart failure after you needed IV water pills (diuretics). It’s mainly for adults with a recent heart-failure flare and specific heart/lab signs, while carefully excluding certain low blood pressure, kidney issues, and electrolyte or acid–base problems.
SamaraAges 18 years+ - NCT07325942Recruiting
Low vs high volume high-intensity interval training for heart failure
This study compares two different types of high-intensity interval exercise programs (one shorter, one longer) in people with chronic heart failure. It aims to see which program improves heart health and daily function more.
Cairo, Giza GovernorateAges 18 years+ - NCT07657650Recruiting
Imaging test for heart failure patients before revascularization
This trial uses a special imaging scan to see if heart muscle has damage from blocked arteries. It helps doctors decide if a procedure to open blocked arteries might improve your heart function.
BeijingAges 18 years+ - NCT06036615Recruiting
Exercise training for frailty and fall risk in heart failure
This trial tests whether a supervised exercise program can reduce frailty and fall risk in people with chronic heart failure, and what happens when training stops. It may help you feel stronger and more stable.
Thessaloniki, ThermiAges 18–100 - NCT07704424Recruiting
Testing a heart pump for severe right heart failure
This trial is evaluating a new temporary heart pump called CorVad for people who develop severe right heart failure shortly after heart surgery, a heart attack, or a heart transplant. The pump is designed to help the right side of the heart pump blood when medications are not enough.
Hefei, AnhuiAges 18 years+ - NCT04405583Recruiting
Follow-up study for a heart device in heart failure patients
This study follows people with chronic heart failure to see how well an implanted device (called the Occlutech AFR) works and whether it is safe over time. It may help doctors better understand who benefits and how to manage treatment safely.
BesançonAges 18 years+ - NCT04656080Recruiting
Test heart and lung exercise capacity after transplant
This study uses a treadmill or stationary bike test to measure how well your heart and lungs work after a heart transplant. It may help researchers see whether this type of testing is safe and useful in transplant follow-up.
Dallas, TexasAges 18 years+ - NCT05769036Recruiting
Biventricular vs left bundle pacing for heart failure outcomes
This trial compares two types of heart pacing to see which improves outcomes for people with heart failure. It may help those who need pacing to better coordinate heartbeats and relieve symptoms.
TomskAges 18–80 - NCT06101693Recruiting
Biomarker study for suspected heart failure
This study looks at certain proteins in your blood to help doctors better understand and diagnose a type of heart failure called HFpEF. You might be able to join if your doctor recently ordered a blood test for NT-proBNP because they thought you might have heart failure.
GlasgowAges 18 years+ - NCT06161402Recruiting
Elastic band exercise for muscle loss in heart failure patients
This trial tests whether a simple at-home exercise program using elastic bands can help older adults with heart failure who also have muscle weakness or low muscle mass (sarcopenia). The goal is to improve strength and daily function.
Hong KongAges 50 years+ - NCT06270498RecruitingPhase 4
Oral iron for heart failure: exercise and quality of life study
This study tests whether an oral iron supplement (a pill called sucrosomial iron) can help people with heart failure who have low iron feel better, have more energy, and walk farther. Participants will take the iron pill or a placebo (a pill without the active ingredient) for a period and will do exercise tests and answer questionnaires to see how they improve.
Pisa, TuscanyAges 18 years+ - NCT06350695Recruiting
Compression stockings for heart failure with leg swelling
This trial tests whether wearing compression stockings can help people with heart failure who have leg swelling. Researchers want to see if stockings reduce fluid buildup and improve daily life.
Dallas, TexasAges 18 years+ - NCT06501768RecruitingPhase 1/Phase 2
Genistein for heart failure inflammation
This trial tests a natural substance called genistein (found in soy) to reduce inflammation in people with heart failure. It may help your heart work better and feel better.
LjubljanaAges 40–80 - NCT06541509RecruitingPhase 1/Phase 2
Semaglutide for heart failure in overweight patients
This trial studies whether the drug semaglutide can help people with heart failure who are overweight. It aims to see if the drug improves heart function and symptoms.
Palo Alto, CaliforniaAges 20–80 - NCT06555757Recruiting
Using AI and sound to predict heart failure worsening
This trial uses a smartphone app to record sounds from your chest and breathing. An AI system will analyze these sound patterns to predict when heart failure symptoms might get worse, so you can get help sooner.
Cambridge, CambridgeshireAges 18 years+ - NCT06585761Recruiting
SGLT2 inhibitors for heart failure: effect on inflammation
This trial tests whether a type of diabetes medicine called SGLT2 inhibitors can lower inflammation and stress markers in people with heart failure. It may help reduce damage to the heart and improve symptoms.
Kafr ash ShaykhAges 18–80 - NCT06650995Recruiting
Ablation and Exercise for Heart Failure with Normal Pumping
This study tests whether a combination of catheter ablation (a procedure to correct irregular heartbeats) and a structured exercise program can improve symptoms and quality of life in people with diastolic heart failure and a recent onset of persistent atrial fibrillation.
MunichAges 18–99 - NCT06726109Recruiting
FOCUS study on acute heart failure
This trial is studying patients admitted to the hospital for acute heart failure. It will collect information to better understand and treat people with low heart pumping strength (ejection fraction less than 40%) and fluid retention.
Genk, BelgiumAges Any age - NCT06805253Recruiting
Heart recovery after surgery for leaky aortic valve
This trial studies how well the heart's main pumping chamber (left ventricle) recovers after surgery to fix a leaky aortic valve. It is for people who also have a leaky mitral valve and an enlarged left ventricle, and who are having their first planned valve surgery.
MoscowAges 18 years+ - NCT07108231Recruiting
Breathing muscle training for hospitalized heart failure patients
This trial tests whether training the muscles you use to breathe can help people recover while in the hospital for heart failure. If you are stable enough, you may be able to join.

Common questions
- Are there clinical trials for acute heart failure?
- Yes. Clin2 currently lists 434 recruiting acute heart failure 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 acute heart failure 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 acute heart failure 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.
