Recruiting studies
- NCT07444931Recruiting
Predicting cardiac arrest risk in heart disease patients
This study looks at factors that may help predict sudden cardiac arrest in people with coronary artery disease. If you have a recent diagnosis of significant blockage or a heart attack, joining this trial could help improve risk assessment.

Heart MRI Study for Dilated Heart Muscle Disease
This research uses cardiac MRI scans and patient data to better predict outcomes in people with dilated cardiomyopathy—a condition where the heart's main pumping chamber becomes enlarged and weakened. Participating could help doctors improve how they care for similar patients in the future.
Jinan, ShandongAges 18 years+ - NCT06898827Enrolling by invitation
Virtual reality distraction therapy for cardiac rehab
This trial tests whether using virtual reality (VR) during cardiac rehabilitation can help distract you from discomfort or anxiety. If you have a heart condition or have had a heart event and are starting rehab, you may be able to join.
MsidaAges 40 years+ - NCT06605833Enrolling by invitation
Heart health after immunotherapy for melanoma
This study looks at heart health in people who have finished immunotherapy for melanoma. It uses MRI scans to check for any heart problems that may have developed after treatment.
LondonAges 18 years+ - NCT06566625Recruiting
MRI before heart catheterization for heart attack
This trial compares using a cardiac MRI before the standard catheterization (angiogram) in people with a suspected heart attack that doesn't show the typical ECG changes. It aims to see if the MRI can help guide decisions and avoid unnecessary procedures.
Stockholm, SwedenAges 18 years+ - NCT06575101Recruiting
Energy Use in Cardiac Arrest Patients During Temperature Control
This study will measure how much energy your body burns and what fuels it uses (like fat or sugar) during temperature management after a cardiac arrest. It aims to learn how to better support your recovery.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06794697Recruiting
Does admission day affect anxiety before heart surgery?
This study looks at whether the day you are admitted to the hospital for planned heart surgery affects your anxiety levels before the operation. The goal is to help hospitals schedule admissions in a way that lowers stress for patients.
RennesAges 18 years+ - NCT06626035RecruitingPhase 3
Pain Medicine Study for Children Having Heart Surgery
This study tests a pain medicine for children having heart surgery. It aims to see if the medicine works well and is safe for managing pain after the operation.
Oakland, CaliforniaAges 3–18 - NCT07002294Recruiting
Specialist care after cardiac arrest recovery trial
This trial tests whether care from a specialist team helps people recover better after a cardiac arrest outside the hospital. If you were revived and brought to the emergency department with a pulse, you might be eligible.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06840327Recruiting
Oxygen levels during heart bypass surgery and recovery
This study looks at how different oxygen levels during heart bypass surgery might affect recovery. It aims to see if keeping oxygen at a certain level can improve outcomes for people having surgery where a vein from the leg is used to bypass a blocked heart artery.
ToulouseAges 18 years+ - NCT06879769Recruiting
Better heart CT scan preparation study
This study looks at how to improve the preparation and imaging techniques for heart CT scans. It may help make the scan more comfortable and accurate for people who already have a heart CT scheduled.
Stockholm, HuddingeAges 18 years+ - NCT06516432Recruiting
Nerve block and lactate in heart surgery
This study looks at how a nerve block near the breastbone (parasternal block) affects lactate levels in the blood for patients having heart surgery. It aims to understand if this pain management technique can help keep lactate levels normal during recovery.
Guadalajara, JaliscoAges 18 years+ - NCT06425614Recruiting
Blood Cell Recycling During Heart Surgery Trial
This trial tests whether giving back a patient's own platelets and red blood cells during heart surgery can reduce bleeding and the need for donor blood transfusions. It is for people having certain types of high-risk heart surgery with a heart-lung machine.
Bordeaux, FranceAges 18 years+ - NCT06467968Recruiting
Heart analysis during DOTATOC PET/CT for neuroendocrine tumors
This study looks at how a PET/CT scan (called gallium-68 DOTATOC) can also check your heart health while scanning for a neuroendocrine tumor. It aims to see if the routine scan can give extra information about your heart function without any extra visits or radiation.
Vandœuvre-lès-NancyAges 18 years+ - NCT06178744Recruiting
AI in heart transplant ultrasound study
This study uses artificial intelligence to look at echocardiograms (ultrasounds of the heart) from heart transplant patients. It aims to see if AI can help predict rejection or other problems, potentially reducing the need for biopsies.
Rochester, MinnesotaAges 18 years+ - NCT06015191Recruiting
Remote heart rehab for teens with congenital heart disease
This trial tests a home-based cardiac rehab program for adolescents with certain types of congenital heart disease. It aims to help you exercise safely and improve your fitness using online coaching and monitoring.
Kansas City, MissouriAges 12–19 - NCT05819528Recruiting
Study of primary cardiac lymphoma treated with anti-CD20 therapy
This trial looks at people with lymphoma that involves mainly the heart (and possibly the lining around the heart) and was treated first with chemotherapy plus an anti-CD20 antibody. The goal is to understand outcomes from this specific treatment approach in patients diagnosed over a defined time period.
Pagani, SalernoAges 18 years+ - NCT04754022Recruiting
Blood use during heart surgery in younger adults
This study looks at how much donated blood (blood products) is needed for younger adults during heart surgery that uses a heart-lung machine. It may help doctors choose safer, more appropriate blood-saving plans for people like you.
Portland, MaineAges 18–65 - NCT04890821Recruiting
Percutaneous ring repair for leaking tricuspid valve
This early study tests a minimally invasive device that helps tighten (repair) the tricuspid valve ring to reduce severe leaking. It may help people who still have symptoms from right-sided heart failure even after taking the best available medicines.
Hackensack, New JerseyAges 18 years+ - NCT06575556Recruiting
Using MRI instead of CT for follow-up after Ross procedure
This study compares MRI scans to CT scans for following up patients who had the Ross procedure (a type of heart valve surgery) using the 'loose jacket' technique. The goal is to see if MRI can successfully replace CT, avoiding the radiation and dye used in CT scans.
AswānAges Any age - NCT03393169Recruiting
Tracking complications after heart surgery in adults
This study looks at how often and why complications happen after heart surgery, using information from the hospital stay. It may help improve care by understanding postoperative risks and outcomes.
ParisAges 18 years+ - NCT04284839RecruitingPhase 3
Blood thinner pills vs warfarin after heart surgery
This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,308 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.
