Recruiting studies
- NCT07272798Recruiting
Heart confidence after pulmonary hypertension surgery
This study looks at how confident patients feel about managing their heart health after surgery for chronic thromboembolic pulmonary hypertension. It may help doctors understand how to better support recovery.

Pacing and heart pressure in HFpEF exercise
This study tests whether a special pacing setting during exercise can help improve heart filling pressures in people with heart failure with preserved ejection fraction (HFpEF) who already have a DDD pacemaker. If you have HFpEF and a pacemaker, you may help researchers find better ways to manage your condition during activity.

Heart changes in Fabry disease: an observational study
This study looks at people with Fabry disease, a genetic condition that can cause the heart muscle to thicken. Researchers want to understand how the heart's blood vessels change over time, which may help improve care for Fabry disease.
BeijingAges 18 years+ - NCT07264400Recruiting
Pregnancy exercise and baby heart health
This trial looks at how a mother's physical activity during pregnancy might affect her newborn's heart function. It is part of a larger study called PregMouv, and researchers want to see if staying active leads to better heart rate variability in babies.
Clermont-FerrandAges 1 day–3 days - NCT07267416Recruiting
Monitoring to prevent confusion after heart surgery
This trial uses brain monitoring during heart surgery to try to prevent post-surgery confusion or memory problems. It may help if you are having valve repair or bypass surgery.

Study on heart-lung machine fluid and its effects in heart surgery
This study looks at how the fluid used to fill the heart-lung machine affects the body's chemistry and recovery in patients having heart surgery. It may help doctors choose the best fluid for better outcomes after bypass surgery.
LundAges 18 years+ - NCT07267013RecruitingPhase 2
Testing clindamycin instead of vancomycin in aortic heart surgery
This study tests if clindamycin, a common antibiotic, works as well as vancomycin to prevent infections during heart surgery on the aorta (the main artery from the heart). Patients must be having planned morning surgery with the heart-lung machine and understand French.
Nantes, FranceAges 18 years+ - NCT07268391Recruiting
Advanced scans to understand heart healing after heart attack
This study uses advanced CT scans and blood tests to look at how the heart is damaged and recovers after a first heart attack. It may help doctors find better ways to treat heart attacks in the future.
MadridAges 18 years+ - NCT07268170Enrolling by invitationPhase 2/Phase 3
Heart rate control before heart CT scan
This trial tests two medicines to lower heart rate before a cardiac CT scan in adults who need the scan. It is for people whose heart rate is naturally a bit fast (over 65 beats per minute) but not too fast (under 100 bpm).
HerningAges 30–80 - NCT07262580Enrolling by invitation
Finding meaning in cardiac rehab: a study
This study tests a program to help people in cardiac rehabilitation find personal meaning and purpose. It explores if the program works in individual, group, or paired sessions with a relative.
Odense, Region SyddanmarkAges 18 years+ - NCT07264166Enrolling by invitation
Gene therapy trial for cerebral palsy and HIE
This trial tests a gene therapy given as a nose spray for people with cerebral palsy or HIE. It aims to see if the treatment is safe and helps improve movement over two years.
Monterrey, Nuevo LeónAges 2–65 - NCT04442789Recruiting
Study of lasting effects after COVID-19 hospitalization
This study looks at what health problems remain after a person was hospitalized for COVID-19. It may help doctors understand these long-lasting effects and how to care for people afterward.
GiessenAges 18 years+ - NCT05547165Recruiting
Closing a leaky heart connection early in very small babies
This trial compares an early procedure to close a heart vessel called the ductus arteriosus versus careful observation alone in very low-birth-weight preterm infants. It aims to see whether closing the vessel early can improve outcomes and be done safely.
Birmingham, AlabamaAges 1 week–1 month - NCT05521451Recruiting
Study for adults with heart rhythm problems
This trial is a “clinical cohort” study, meaning it follows adults with certain heart rhythm issues to understand them better. Your participation may help researchers learn what to expect and how best to support people over time.
HamburgAges 18 years+ - NCT07254013Recruiting
LBBAP Pacemaker Monitoring with Portable ECG
This study is testing a portable heart monitoring device to help doctors check how well a special pacemaker (LBBAP) is working. It may help people who need a new or upgraded pacemaker or heart device.
Besançon, FranceAges 18 years+ - NCT07252856Recruiting
Digital support for heart rehab (phase III)
This trial tests a digital tool to help people with heart disease continue their cardiac rehabilitation at home during the maintenance phase. It's for people who have already completed the earlier rehab phase and are ready for long-term support.
LeuvenAges 18 years+ - NCT07251361Enrolling by invitation
Exercise program for heart failure with preserved ejection fraction
This study tests whether a special exercise program that combines different types of training (like aerobic, strength, and balance) can improve heart and muscle function, daily abilities, and quality of life in people with heart failure with preserved ejection fraction (HFpEF). You may benefit if your heart failure is stable and you are able to exercise safely.
Pamplona, NavarreAges 18 years+ - NCT07258706Enrolling by invitation
Study on TAVI results based on patient differences
This trial is for people with severe aortic stenosis who are already scheduled for TAVI (a procedure to replace a narrowed heart valve). It looks at how individual differences affect the procedure's outcomes.
VicenzaAges 18 years+ - NCT07255144Recruiting
Ultrafast ultrasound imaging for children's heart conditions
This study tests a new, faster ultrasound technique to see heart structure and blood flow in children with or without congenital heart disease (CHD). It aims to improve imaging without risk, using a short scan during a regular check-up.
Pessac, FranceAges Any age - NCT06706323Recruiting
Depression after heart surgery study
This study looks at depressive symptoms in people who have had heart bypass surgery. It aims to understand how patients feel emotionally after surgery and may help improve care.
ZurichAges 18–90 - NCT07240441Recruiting
Comparing heart ablation methods for post-heart attack VT
This trial tests two ways to do a heart procedure (ablation) in people who have had a heart attack and now have dangerous fast heart rhythms. It compares the usual method (inside the heart only) with a method that also works on the outer surface of the heart. The goal is to see which works better to stop these rhythms.
Warsaw, Masovian VoivodeshipAges 18–85 - NCT07246148Recruiting
Noninvasive blood pressure monitoring during aneurysm repair
This study compares a new noninvasive blood pressure monitoring method to the standard method (using a small tube in your wrist) during brain aneurysm repair surgery. If you join, you may avoid the need for a wrist artery line.
SeoulAges 19–80 - NCT07245069RecruitingPhase 2

Heart failure study with adenosine scans to predict recovery
This trial tests whether high-dose adenosine during a heart scan can better predict how well your heart muscle might recover, compared to standard dosing. The information could help doctors personalize treatment for people newly diagnosed with heart failure and a low ejection fraction.

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,291 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.
