This study looks at how well the lungs and heart work together during exercise in people who have had the Fontan operation. The goal is to understand how lung function affects overall fitness, which can help improve care for Fontan patients.
AnkaraAges 8–55 - NCT05173740RecruitingPhase 4
Rehab program for people after an out-of-hospital cardiac arrest
This trial studies a rehabilitation program for adults who survived a first out-of-hospital cardiac arrest. It may help improve recovery after leaving the hospital by using guided follow-up and surveys to see how people are doing over time.
CopenhagenAges 18–65 - NCT05650541Recruiting
Testing a home device to help chronic heart failure
This study tests whether a CardioPulmonary Management (CPM) system device used at home is safe and can improve outcomes for people with chronic heart failure. It may help manage symptoms and reduce complications, especially for higher-risk patients.
Palm Springs, CaliforniaAges 18 years+ - NCT05584722Recruiting
Study risk and resilience in pulmonary arterial hypertension
This study looks at how people with pulmonary arterial hypertension (PAH) and certain genetic risks cope and how their bodies respond over time. It may help researchers understand factors linked to better or worse outcomes, and how different people manage the condition.
Nashville, TennesseeAges 15–80 - NCT05537467Recruiting
Music during exercise for people with heart failure
This trial tests whether listening to music while you exercise can improve how well you can exercise when you have heart failure. It is mainly looking for adults who can safely do an exercise test and communicate in English.
Lexington, KentuckyAges 18 years+ - NCT04323904Recruiting
Hantavirus registry for people with kidney or lung symptoms
This study is a registry, meaning it collects health information and possibly test results from people who have evidence of hantavirus infection along with specific illness symptoms. It may help researchers better understand how hantavirus affects the kidneys or the heart/lungs (and how to recognize it).
Cologne, North-Rhine WestfaliaAges Any age - NCT05388019Enrolling by invitation
VAD clinic visit study for new and returning patients
This trial looks at how well a specialized, multidisciplinary clinic works for people who have a ventricular assist device (VAD) and compares new VAD patients with those who have already had standard follow-up visits. It may help improve how care and check-ins are organized after your VAD is implanted.
Boston, MassachusettsAges 18 years+ - NCT05321459Recruiting
Testing outcome prediction in comatose patients after cardiac arrest
This study looks at tests that may help predict outcomes in people who remain in a coma 3 to 7 days after surviving a cardiac arrest. It may help doctors better estimate recovery and guide care decisions.
BobignyAges 18 years+ - NCT05213572Recruiting
Deep health check study for adults with sickle cell disease
This study looks at how major organs like the brain, kidneys, heart, and liver are affected in adults with sickle cell disease, whether they've had a bone marrow transplant or gene therapy, or are continuing regular treatment. You'll get detailed tests that can help doctors understand the disease better, which may lead to improved care.

Common questions
- Are there clinical trials for cardiopulmonary?
- Yes. Clin2 currently lists 169 recruiting cardiopulmonary 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 cardiopulmonary 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 cardiopulmonary 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.
