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+ - 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+ - 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 - 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 - 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 - NCT05441696Enrolling by invitation
Check a noninvasive heart failure blood-flow measurement in hospital
This study tests a device that measures blood flow and pressure in a noninvasive way (using sensors on the body) for people admitted with worsening heart failure. It may help doctors monitor heart failure and potentially lower the chance of coming back to the hospital.
Palo Alto, CaliforniaAges 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+ - NCT07349797Recruiting
Transdermal GFR system to check kidney function in heart failure
This trial tests a sensor placed on the skin to measure kidney function in adults with heart failure. It may help understand how well the kidneys are working without repeated blood draws.
New York, New YorkAges 18 years+ - 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.
Vandœuvre-lès-NancyAges 18 years+ - NCT06992089Recruiting
Pacemaker study for heart failure with low heart rate
This trial tests a special pacemaker setting to help your heart beat faster during exercise. It may improve your ability to be active if you have heart failure with preserved ejection fraction (HFpEF) and a low resting heart rate.
ValenciaAges 18 years+ - NCT06024746RecruitingPhase 3
Finerenone plus SGLT2i for hospitalized heart failure
This trial tests whether adding two heart medicines together (finerenone and an SGLT2 inhibitor) helps people who are in the hospital for heart failure recover better. It may be an option for you if you are currently hospitalized and your heart stress markers are high.
Fairhope, AlabamaAges 18 years+ - NCT06061627Recruiting
LOT-CRT vs standard CRT for heart failure with NICD
This study compares a newer pacing therapy (LOT-CRT) to standard cardiac resynchronization therapy (BiVP) for people with heart failure who have a specific type of electrical delay in the heart (NICD). The goal is to see if the newer method works better.
Nanjing, JiangsuAges 18–80 - NCT06427343RecruitingPhase 4
IV iron: low dose vs high dose for heart failure with low iron
This study compares two different doses of IV iron (low vs high) to see which works better for people with heart failure and low iron levels. It may help you feel less tired and breathe easier.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06578793Recruiting
Catheter plus vein ablation for atrial fibrillation with heart failure
This trial tests whether adding a vein ablation to standard catheter ablation helps people with persistent atrial fibrillation and heart failure. It aims to find the best treatment to improve heart function and reduce symptoms.
Changsha, HunanAges 18–80 - NCT07029906Recruiting
Testing if beta-blocker side effects are due to expectations
This study tests whether some side effects from beta-blockers are caused by your expectations (the nocebo effect) rather than the drug itself. If you have heart failure and stopped a beta-blocker due to symptoms, this study may help understand your experience and potentially find better ways to manage it.
LondonAges 18 years+ - NCT03215849Enrolling by invitation
Tested pacing device for heart failure with preserved pumping
This trial studies a heart pacing approach in people with heart failure symptoms despite preserved heart pumping. It aims to see whether changing heart timing can improve how you feel and how your heart works during exercise.
CardiffAges Any age - NCT07439159Recruiting
Heart ultrasound to predict outcomes in hospitalized heart failure
This study uses a heart ultrasound (echocardiogram) to predict outcomes in people hospitalized for sudden heart failure. If you are receiving IV fluid-removing medication, the results may help your doctors understand your condition better.

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.
