Jonesboro, ArkansasAges 18 years+ - NCT06774365Recruiting
Heart imaging and blood tests for transplant rejection detection
This study uses advanced heart imaging and blood tests to detect a type of rejection that can happen after a heart transplant. It may help doctors diagnose antibody-mediated rejection earlier and more accurately.
Bari, BariAges 18 years+ - NCT06780722Recruiting
Study of heart and blood circulation issues during a specific organ donation process
This trial is studying heart and blood circulation problems that may happen during a certain type of organ donation (called Maastricht 3). It is for people who donate organs and those who receive them. The goal is to see how the level of oxygen in the blood affects these problems.
AngersAges 18 years+ - NCT06772207Enrolling by invitation
Heart rehab needs in atrial fibrillation patients
This study looks at what heart rehabilitation people with newly diagnosed atrial fibrillation need and how to improve their care. If you were diagnosed with atrial fibrillation in 2022 or 2023 and live in Denmark, you may be eligible.
OdenseAges 18 years+ - NCT06770062Recruiting
How the heart changes after mitral valve repair surgery
This study at Mayo Clinic uses MRI and other tests to see how the heart's main pumping chamber changes shape after robot-assisted mitral valve repair surgery for severe mitral regurgitation. It may help doctors better understand how patients recover.
Rochester, MinnesotaAges 18 years+ - NCT06750939Recruiting
Comparing two sedatives for ICU breathing tube placement
This study compares two medicines (propofol and ketamine) used to help you relax and stay stable while a breathing tube is placed. The goal is to see which one is safer for your heart and blood pressure during this procedure in the ICU.
Köseköy, KocaeliAges 18 years+ - NCT06750536Recruiting
Safety study of a new lung support device for small children
This trial is testing a new device (MiniLung Petite Kit) for babies and young children with severe lung or heart failure. The device helps oxygenate the blood and remove carbon dioxide, giving the lungs and heart a chance to rest and heal.
Bonn, North Rhine-WestphaliaAges Up to 8 months - NCT05631730RecruitingPhase 3
Flecainide plus metoprolol vs metoprolol alone for rhythm control
This trial studies whether adding flecainide to metoprolol can better reduce dangerous heart rhythm problems in people with mitral valve prolapse. It also checks safety and side effects compared with metoprolol alone.
OsloAges 18 years+ - NCT06739005Recruiting
AI model to assess heart surgeon technique in bypass surgery
This study tests whether an artificial intelligence (AI) model can accurately evaluate the surgical technique of heart surgeons performing a common bypass procedure. If you are a first-time bypass patient and do not have certain heart or organ conditions, you may be able to participate and help improve surgical training tools.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06745778Recruiting
Study of heart device signals in patients with left bundle pacing
This study looks at the electrical signals recorded by a special type of pacing lead placed in the heart's left bundle branch. It aims to understand how these signals change over time in people who already have an ICD or CRT-D device.
Wenzhou, ZhejiangAges 18 years+ - NCT05336877Recruiting
Using Medicare data to study pacemaker care after implant
This study looks at Medicare claims to understand how well different pacemakers work in real-world care after they are implanted. You may be included if you are a Medicare patient who received an Aveir VR leadless pacemaker or a single-chamber ventricular pacemaker after the study began.

Parkinson's signs in people with nerve damage
This study looks for early signs of Parkinson's disease in people who have nerve damage in their hands and feet (polyneuropathy) with no known cause, along with drops in blood pressure when standing up. It aims to understand if these early symptoms might predict future Parkinson's.

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,296 recruiting cardiac 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 cardiac 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 cardiac 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.
