Heart health study for people with osteogenesis imperfecta
This study looks at heart structure and function in children and adults with osteogenesis imperfecta (OI), a condition that affects bones. Researchers want to understand how OI may impact the heart.

PET scan study for heart scarring in heart failure
This study uses a special PET scan to look for scarring (fibrosis) in the heart muscle of people with heart failure. It may help doctors better understand why some hearts get stiff or weak.
Coimbra, Coimbra DistrictAges 18 years+ - NCT07297589RecruitingPhase 3
CT scan of heart fat after heart attack
This study uses a CT scan to look at the layer of fat around the heart in people who recently had a heart attack and have type 2 diabetes and obesity. It aims to understand how this fat relates to inflammation and heart health.
León, GuanajuatoAges 18 years+ - NCT07298122Recruiting
Heart imaging for hidden clots in ESUS stroke with left ventricular disease
This study uses advanced heart scans (MRI or CT) to look for blood clots in the heart of people who had a stroke with an unclear cause, specifically if they also have a mild heart condition affecting the left ventricle. The goal is to find hidden clots that might be causing strokes.
Milan, LombardyAges 18 years+ - NCT07298473Recruiting
Redo ablation for recurrent atrial fibrillation with Sphere-9 catheter
This trial tests a new catheter and system for people who have had one previous ablation for atrial fibrillation but still have symptoms. It aims to see if a repeat procedure can safely and effectively treat recurrent episodes.
Birmingham, AlabamaAges 18 years+ - NCT07301489Recruiting
Heart study for lung screening participants
This trial adds a heart health check to an existing lung cancer screening study. It looks at old chest CT scans to assess heart disease risk and asks you to return for a follow-up visit one year later.
Lørenskog, AkershusAges 60–79 - NCT07308704Recruiting
Using AI to spot heart muscle disease on echocardiograms
This study at Mayo Clinic is testing an artificial intelligence (AI) tool that analyzes echocardiograms (ultrasound of the heart) to find early signs of four types of heart muscle disease. If the AI flags a high-risk pattern, doctors can learn whether acting on that alert helps catch the condition sooner.
Rochester, MinnesotaAges 18 years+ - NCT07314268Recruiting
Study of tiny blood particles in heart amyloidosis
This study looks at tiny particles called extracellular vesicles in the blood of people with a specific type of heart amyloidosis. It aims to find better ways to track the disease and predict outcomes.
São Paulo, São PauloAges 18 years+ - NCT07315308Recruiting
Nerve block before heart surgery and painkiller use
This study tests whether a numbing injection in the chest before heart surgery can reduce the amount of pain medicine needed during the operation. It may help you manage pain better and recover more comfortably.
Gaziantep, SahinbeyAges 18–65 - NCT07325370Recruiting
Brain training with feedback for anxiety in pregnancy loss
This trial tests if a non-invasive brain training method (neurofeedback) can help women with recurrent pregnancy loss who also have anxiety. It aims to improve heart rate regulation and reduce anxiety using a closed-loop system that gives you real-time feedback.
Shenyang, LiaoningAges 18–45 - NCT07334457Recruiting
Platelet Changes While on ECMO Support
This study looks at how blood cells called platelets change in people who are on a heart-lung machine (ECMO) in the ICU. It aims to better understand how the body responds to this support.
StrasbourgAges 18 years+ - NCT07176286RecruitingPhase 2
PET scan study for diagnosing Lewy body dementia
This trial is testing a special PET scan that uses a radioactive tracer (18F-mFBG) to see how much it is taken up by the heart. The goal is to help tell Lewy body disease (Parkinson's or Lewy body dementia) apart from other brain disorders.
Houston, TexasAges 18 years+ - NCT06690151Recruiting
Babies with heart defects and development support
This study looks at how a serious heart condition before birth may affect a baby's brain development. It follows babies and their parents to better understand and support these children as they grow.

Study on kidney injury after major surgery in children
This trial looks at how often children develop kidney problems after major surgery that isn't on the heart or kidneys. The goal is to learn more about these injuries and how to prevent them.
Perth, Western AustraliaAges birth–16 years - NCT07351825Recruiting

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,309 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.
