Recruiting studies
- NCT07166965Enrolling by invitation

Philadelphia, PennsylvaniaAges 18 years+ - 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 - 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.

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+ - 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+ - 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 - 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 - 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+ - 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+ - 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+ - NCT04344912Recruiting
Study of COVID-19 effects on heart emergency care
This study looks at how the COVID-19 outbreak affected care for people admitted to the cardiac intensive care unit. It may help hospitals improve how they plan and respond during major outbreaks.
ParisAges 18 years+ - NCT06560047Recruiting
Early catheter ablation for atrial fibrillation with heart failure
This trial tests whether early catheter ablation (a procedure to fix irregular heartbeats) helps people who have both heart failure and atrial fibrillation. It looks at how this treatment affects your heart function and quality of life.
AalborgAges 18–80 - NCT07667452Recruiting
AI patch study for heart failure recognition
This trial tests a new AI computer model that uses a single feature from a wearable patch to help recognize heart failure more easily. If you have heart failure with moderate to severe symptoms, this study may help improve how we monitor your condition.
Hangzhou, ZhejiangAges 18 years+ - NCT07284446Recruiting
Depression, memory, and outcomes in heart failure patients
This study looks at how depression and memory problems affect recovery in people hospitalized with worsening chronic heart failure. It aims to find better ways to support patients during their hospital stay.
KaunasAges 18–85 - NCT07047547Recruiting
Vericiguat study for kidney disease and heart failure patients
This trial tests how a medication called vericiguat works in people with both chronic kidney disease and heart failure. It aims to see if the drug helps manage these conditions together.
Guangzhou, GuangdongAges 18–80 - NCT05960968Recruiting
Hospital heart failure registry for adults in Santiago
This is a registry study that collects information from adults hospitalized for heart failure in Santiago. It aims to better understand heart failure in real-world patients, including differences by sex, by tracking what happens during the hospital stay.
Santiago, Santiago MetropolitanAges 18 years+ - NCT06319274RecruitingPhase 2
Prostacyclin for lung infection patients on a ventilator
This study tests a medicine called prostacyclin (given through a vein) to see if it helps people on a breathing machine with a lung infection. The goal is to reduce inflammation and improve recovery.
CopenhagenAges 18 years+ - NCT06019169Recruiting
Yoga for Heart Failure: Improving Quality of Life
This study tests if practicing yoga can improve quality of life and well-being for people with stable heart failure. You can join whether you are new to yoga or have done a little before.
ParisAges 18 years+ - NCT07463885Recruiting
Breathing on your own vs machine breathing for low oxygen
This study tests whether letting patients with serious breathing problems breathe on their own (with a breathing tube still in place) is better than the usual way of using the ventilator to do all the breathing. It may lead to faster recovery and less harm.
Oslo, OsloAges 18 years+ - NCT07450846Recruiting
Heart-lung interaction in severe breathing problems
This study looks at how the heart and lungs interact in patients with acute respiratory distress syndrome (a severe lung condition) who are on a breathing machine. Researchers will use ultrasound to check heart function at different times during treatment.
Le Kremlin-BicêtreAges 18 years+ - NCT07157696Recruiting
Advanced oxygen monitoring for chronic lung or heart disease
This study tests a more advanced way to monitor oxygen levels and deliver oxygen therapy at home for people with chronic lung or heart conditions who have acute breathing problems. It aims to see if this approach improves care and quality of life.
Ferrara, ItalyAges 18–80 - NCT05089149Recruiting
Check how lung ultrasound helps manage heart failure congestion
This study looks at people with long-term worsening heart failure who are coming to the hospital for a planned visit, to see how checking “congestion” (fluid buildup) may guide care. It may help the team understand whether lung ultrasound can better assess who needs treatment changes.

Common questions
- Are there clinical trials for acute heart failure?
- Yes. Clin2 currently lists 418 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.
