Recruiting studies
- NCT06409585Recruiting
Heart muscle disease imaging study for scarring
This study uses advanced imaging (PET/MR or PET/CT) to look at scarring (fibrosis) in the heart muscle. It is for people with various heart muscle diseases, including heart failure with preserved pumping, thickened heart muscle, high blood pressure-related heart damage, heart inflammation, and others.

Registry and blood/tissue study for certain sudden heart death causes
This study builds a registry and collection of samples to better understand families affected by sudden heart death and related heart rhythm problems that are not clearly caused by a heart attack. It may help researchers identify patterns and improve future care, and it offers a way for patients and families to contribute to research.
Rochester, MinnesotaAges Any age - NCT05139849RecruitingPhase 3
Testing vasopressin and steroids with adrenaline in cardiac arrest
This trial studies whether adding vasopressin and steroids to the standard emergency medicine adrenaline improves survival after out-of-hospital or in-hospital cardiac arrest. If you qualify, the treatment is chosen by chance (randomized) to help doctors learn which approach works best.
GothenburgAges 18 years+ - NCT05776797Recruiting
Ablation vs best medicines for CRT patients with permanent atrial fibrillation
This trial compares two approaches—an AV junction ablation procedure versus continued best medical treatment—in people who already have a heart device for heart failure (CRT) but still have ongoing permanent atrial fibrillation. It aims to improve how well your heart rhythm is controlled and how effectively the device can pace your heart.
Liberec, Liberec RegionAges 18–85 - NCT06175650Recruiting
Female-focused recovery plan after heart surgery
This study looks at how to improve recovery after heart surgery, especially for women. It reviews medical records from people who had heart surgery in the past or will have it in the next few years at two hospitals in Amsterdam.
Amsterdam, North HollandAges 18 years+ - NCT05694572Recruiting
Device follow-up for certain MicroPort CRM heart implants
This study checks how well specific MicroPort CRM heart devices and leads work in real life over time. If you already have one of these FDA/market-approved implants and can be followed yearly, the study helps the company monitor safety and performance.
LisbonAges 18–90 - NCT07852390Recruiting
Pacing after heart surgery in children
This study tests whether using a pacemaker after heart surgery helps children's hearts recover and pump more efficiently. It is for children under 12 years old who are having heart surgery at Lurie Children's Hospital.
Chicago, IllinoisAges Up to 12 years - NCT07829887Recruiting
Measuring brain oxygen after cardiac arrest
This study tests a device that measures oxygen levels in the brain during recovery from cardiac arrest. It aims to see if monitoring brain oxygen helps doctors make better treatment decisions after the heart restarts.
Calgary, AlbertaAges Any age - NCT05593679Recruiting
Registry study for heart PYP scans in possible ATTR amyloidosis
This study collects information from adults who have been diagnosed with, or are being checked for, ATTR amyloidosis (a condition where abnormal protein builds up in the body) using a heart PYP scan. Your participation may help doctors better understand how these scans relate to diagnosis and follow-up over time.
New Taipei CityAges 20 years+ - NCT07798011Recruiting
Faster breathing tube removal after pediatric heart surgery
This study compares two ways of helping children wake up and breathe on their own after minimally invasive heart surgery. One group gets a drug to quickly reverse the muscle relaxant, while the other group waits for it to wear off naturally. The goal is to see which method allows a safer, earlier breathing tube removal.
HanoiAges 2–18 - NCT06554925Recruiting
Sex differences in cardiac surgery patients
This study looks at how men and women may differ in their experiences and outcomes after heart surgery. It may help doctors provide better care for all patients.
Amsterdam, North HollandAges 18 years+ - NCT07766135Recruiting
Liver and blood clotting in heart amyloidosis
This study looks at how the liver and blood clotting are affected in people with a type of heart disease called transthyretin amyloidosis. It may help doctors better understand and manage this condition.
Messina, SicilyAges 18 years+ - NCT07752732Recruiting
Heart scans for amyloidosis in people with severe aortic valve stenosis
This study looks at how often cardiac amyloidosis occurs in people with severe aortic valve stenosis. It uses different heart scans to find out more. If you have both conditions, this research may help doctors understand your situation better.
TübingenAges 18 years+ - NCT06607471Recruiting
Study on non-ischemic heart muscle diseases
This study looks at different types of heart muscle diseases that are not caused by blocked arteries (non-ischemic cardiomyopathies). It aims to better understand how to diagnose, predict outcomes, and treat these conditions by gathering information from many patients over time.
Milan, MilanoAges 18 years+ - NCT07722637Recruiting
Cardiac rehab's effect on cell health in heart disease
This study looks at whether a heart rehab program can affect a type of cell damage (ferroptosis) in people who recently had heart artery disease. It could help show why rehab is good for recovery.
Kayseri, KayseriAges 18–75 - NCT04331249Recruiting
Monitoring heart device during and around your procedure
This trial looks at how to manage and check implanted heart devices (pacemakers/defibrillators) during and around a planned procedure. It may help teams improve safety and decision-making during surgery or catheter procedures.
Fürth, BavariaAges 18 years+ - NCT07706816Recruiting
Remote stress recovery program for young heart attack survivors
This study tests a remote program to help people under 55 recover from the stress of a heart attack. It aims to see if the program is practical and helpful for reducing distress after a heart attack.
UppsalaAges 18–55 - NCT06469515Recruiting
Thinking recovery after heart surgery in older adults
This study looks at how older adults recover their thinking and memory skills after heart surgery. You may be asked to do simple computer or paper tests to see how your brain heals.
GothenburgAges 65 years+ - NCT07636642Recruiting
New Heart Attack Blood Test Accuracy Study
This study compares two versions of a sensitive heart attack blood test to see how well the newer version can quickly rule out heart attacks in the emergency department. You'll have blood drawn as part of your normal care, and researchers will review your medical records.
Edinburgh, MidlothianAges 18 years+ - NCT06323668Recruiting
Device removal vs full medical treatment for infected heart devices
This trial compares removing a heart device (like a pacemaker) versus using antibiotics and other medical care to treat an infection. It may help doctors decide the best way to handle infections related to these devices.
CopenhagenAges Any age - NCT05917717Recruiting
Test a care bundle for adults after witnessed cardiac arrest
This trial studies a “care bundle” approach using special devices to improve care after an out-of-hospital or witnessed cardiac arrest. It may help by standardizing emergency treatment for people right after their heart stops.
Southampton, EnglandAges 18–120 - NCT07604220Recruiting
Exosome Signatures in Cardiac Sarcoidosis Disease Activity
This study looks for disease markers in tiny particles called exosomes in your blood to better understand cardiac sarcoidosis (a condition where inflammation affects the heart). By measuring these markers alongside your standard heart imaging, researchers hope to find better ways to detect and monitor the disease.
Rochester, MinnesotaAges 18 years+ - NCT05698277Recruiting
Ultrasound to track baby heart function in heart disease
This study uses automated ultrasound measurements to track how a baby’s heart is working during pregnancy. It compares babies who have a specific congenital heart problem with babies without it, to understand what ultrasound can detect.

- 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.
