Breast artery calcium scan and heart disease risk in women
This study looks at calcium deposits seen in breast arteries during a routine mammogram to see if they can help predict heart disease risk in women aged 55 to 65. It may help doctors find heart risk earlier without extra tests.
Manhasset, New YorkAges 55–65 - NCT07815119Recruiting
Comparing two heart imaging methods before a stroke-prevention procedure
This study compares two imaging methods (TEE and CCTA) used before a procedure to close a small pouch in the heart, which helps prevent strokes in people with atrial fibrillation. Participants will be randomly assigned to one method, and both groups will be checked after 3 months to see which imaging works better.

Xi'an, ShaanxiAges 3–80 - NCT04490317Recruiting
Study follows people with carbon monoxide poisoning in Korea
This study looks at people who have been sickened by carbon monoxide (CO) from an accident or exposure. It aims to better understand what happens over time, which could help improve care and outcomes in the future.
Wŏnju, Gangwon-doAges Any age - NCT04833751Recruiting
Study of heart and brain monitoring around heart surgery anesthesia
This study collects heart and brain signal information before and during anesthesia for people having cardiovascular surgery or procedures. The goal is to better understand risk and outcomes, and to improve how anesthesia is assessed.
SeoulAges 19 years+ - NCT07793916Recruiting
Heart device and tricuspid valve function study
This study looks at how heart devices like pacemakers affect the tricuspid valve over time. It uses ultrasound to check valve function and see if the device causes any problems.
Seoul, SeoulAges 19 years+ - NCT07792694Recruiting
Predicting dangerous heart rhythms with smart software
This study uses computer software to analyze heart rhythm recordings from patients in the hospital to predict dangerous irregular heartbeats (arrhythmias). It aims to improve early detection and care for patients with heart conditions.
Eindhoven, North BrabantAges 18 years+ - NCT07799363Recruiting
Heart imaging test comparison for patients getting a new heart valve
This study compares two heart imaging scans to see if a newer CT scan works as well as an MRI for checking blood flow and heart tissue in people having a heart valve replacement. It may help improve care for patients with aortic stenosis.
Huddinge, Stockholm CountyAges 60 years+ - NCT07796217RecruitingPhase 4
Comparing blood thinners after a heart attack
This study compares two ways to lower the chances of another heart attack: taking the standard medicine (clopidogrel) versus taking a combination of aspirin and a lower dose of a blood thinner (rivaroxaban). If you join, you'll be assigned to one of these options to see which works better for people like you.
Seongnam-si, Gyeonggi-doAges 19 years+ - NCT07791407Recruiting
Heart imaging to guide defibrillator placement in heart failure
This study uses an MRI scan of the heart to better identify which people with heart failure need a defibrillator along with a special pacemaker (cardiac resynchronization therapy). The scan may help doctors decide if the device could improve your heart's pumping and reduce risks.
Madurai, Tamil NaduAges 18 years+ - NCT07782216Recruiting
Studying brain proteins after acute brain injury
This study looks at how certain brain proteins (called biomarkers) behave in the blood after an acute brain injury. The goal is to see if these proteins can help doctors quickly assess the severity of the injury. Participation involves giving blood samples at specific times after your injury.
Pécs, BranyaAges 18 years+ - NCT07779720Recruiting
Personalized fluids for emergency sepsis care
This trial tests a personalized approach to giving IV fluids to patients with sepsis in the emergency department. It uses a device to monitor your heart and blood flow to help doctors decide how much fluid you need, which may improve recovery.
Murray, UtahAges 18 years+ - NCT07775742Recruiting
Exercise programs after heart bypass surgery
This study compares two exercise programs for people who have recovered from heart bypass surgery. One program involves high-intensity interval training, and the other is a home-based rehabilitation program. The goal is to see which program helps improve recovery and overall health.
MadinahAges 55–58 - NCT07773870Recruiting
Cold weather exposure and heart healing after stent placement
This study looks at how living or working in cold regions affects heart recovery after a stent procedure. Participants will have heart imaging at the start and again 6 months later to see if cold exposure impacts heart function.
Beijing, Please Select An Option BelowAges 18–80 - NCT07772817Recruiting
Chest-strap heart monitor for active people
This study compares a new chest-strap heart monitor to a traditional adhesive patch monitor. You will wear both while doing your normal exercise routine to see if the strap is easier to use and gives good readings.
Scottsdale, ArizonaAges 22 years+ - NCT06290154Recruiting
Heart health after liver transplant study
This study looks at factors that affect heart health after a liver transplant. It may help doctors better predict and manage heart problems in people with end-stage liver disease who are getting a new liver.
Guangzhou, GuangdongAges 18 years+ - NCT06564675Recruiting
Using EEG brain waves to predict recovery after cardiac arrest
This trial uses a special EEG device (Brainstatus) to measure brain activity in people who are still unconscious after a cardiac arrest. The goal is to see if certain brain waves can predict a good recovery.
HelsinkiAges 18–110 - NCT07762144Enrolling by invitation
Recovery after cardiac arrest
This trial collects health information from people who have survived a cardiac arrest (when the heart stops) and have been brought back to life. The information may help doctors improve care and recovery after this event.
Beijing, Beijing MunicipalityAges Any age - NCT07763340Recruiting
Photon-counting ct heart scan for people with coronary stents

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,288 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.
