Sleep quality and self-care in heart failure
This study looks at how sleep quality affects the ability of people with heart failure to manage their own health. It aims to find if better sleep leads to better self-care.
IzmirAges 18 years+ - NCT02638142Recruiting
Testing IV diuretic treatment for sudden worsening heart failure
This trial studies how an IV (into-the-vein) “water pill” (furosemide/loop diuretic) works in people whose heart failure has suddenly gotten worse. It may help doctors find the best way to reduce fluid-related symptoms like breathing trouble and swelling.
Chioggia, VeneziaAges 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 - 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 - NCT06604468Recruiting
Portable chest device for detecting lung fluid in heart failure
This trial tests a small, portable device worn on the chest that measures changes in fluid levels in your lungs to help detect early signs of fluid buildup (pulmonary congestion). This could help people with heart failure avoid emergency hospital visits.
Montreal, QuebecAges 18 years+ - NCT06587854Recruiting
Study on fluid congestion in acute heart failure patients
This study looks at different patterns of fluid buildup in people with acute heart failure. It aims to understand how these patterns relate to treatment with water pills (diuretics) and may help improve care.
GroningenAges 18 years+ - 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+ - 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 - NCT06099158Recruiting
Heart failure trial guided by HeartLogic technology
This trial tests if using HeartLogic, a feature in your heart device that tracks early warning signs, can help your care team manage your heart failure better and keep you out of the hospital. If you already have a compatible CRT-D or ICD and use remote monitoring, you may be able to join.
Hellerup, Capital RegionAges 18 years+ - NCT06364644Recruiting
Reducing heart failure risk in low-income adults with diabetes
This study looks at how low income and diabetes together raise the risk of heart failure. It offers a program to help you manage your health and reduce that risk.
Baltimore, MarylandAges 30–70 - 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+ - NCT06222099Recruiting
Heartfelt study for chronic heart failure with swelling and adherence challenges
This trial tests a program to help people with chronic heart failure who have swelling in their feet and legs and struggle to follow their care plan. It aims to reduce hospital visits by improving daily monitoring and medication use.
Little Rock, ArkansasAges 22 years+ - NCT06092437Recruiting
Testing a personalized diuretic plan for acute heart failure
This trial is testing whether a diuretic (water pill) dose tailored to each patient works better for treating fluid buildup during a heart failure flare-up. It may help you get the right amount of medication faster and avoid complications.
Heerlen, LimburgAges 18 years+ - NCT06051058Recruiting
App for managing health after hospital discharge
This study tests a smartphone app designed to help people with multiple health conditions manage their care after leaving the hospital. It may help you feel more supported and avoid confusion during the transition from hospital to home.
Boston, MassachusettsAges 55 years+ - NCT06009276Recruiting

Virtual care after heart failure hospitalization
This trial tests whether a home, virtual-care program after a recent heart failure hospital visit can improve recovery and outcomes. You may be invited if you recently left the hospital for heart failure and meet specific heart and lab test thresholds.
Hamilton, OnatrioAges 18 years+ - NCT05537467Recruiting
Music during exercise for people with heart failure

Common questions
- Are there clinical trials for heart failure?
- Yes. Clin2 currently lists 949 recruiting 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 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 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.
