New heart-ablation method for long-lasting arrhythmias
This study tests a new way to destroy the tissue causing dangerous heart rhythms using a detailed model of how the heart's electrical signals spread. It may be an option for people with long-lasting atrial fibrillation or hard-to-control ventricular arrhythmias who are already scheduled for a standard ablation procedure.
Madrid, MadridAges 18 years+ - NCT07393074Recruiting
Liver cancer and nervous system study
This study looks at how the nervous system works in people with liver cancer (hepatocellular carcinoma) or liver scarring (cirrhosis) who need a liver biopsy. It aims to see if there is a link between the nervous system and liver tumors.
LyonAges 18 years+ - NCT06716840Recruiting
Remimazolam for sedation after heart surgery
This trial tests a medication called Remimazolam Besylate to sedate patients who need a breathing tube after heart surgery. The goal is to help patients relax while they recover in the intensive care unit.
Hangzhou, ZhejiangAges 18 years+ - NCT07388355Recruiting
Ease of use study for a new heart monitor device
This study tests how easy it is to use a new device that records your heart's electrical activity through a simple patch on your chest. You will need to use a smartphone app with the patch.
New London, North CarolinaAges 18 years+ - NCT05868902Recruiting
Study registry of heart imaging for suspected blocked heart flow
This study collects results from two types of heart imaging—cardiac PET and CardioFlux magnetocardiography—in people with suspected reduced blood flow to the heart. It may help researchers better understand which imaging findings match coronary ischemia and how the tests compare.
Cleveland, OhioAges 40 years+ - NCT07386379Recruiting
Propofol infusion for nausea after heart bypass surgery
This study tests whether a continuous infusion of propofol (a common anesthesia medicine) during and after heart bypass surgery can reduce postoperative nausea and vomiting. If you are having planned bypass surgery and meet basic health criteria, this trial may help find a better way to feel more comfortable after your operation.
Istanbul, Outside of the USAges 18 years+ - NCT07382128Recruiting
Heart MRI to Understand Hypertrophic Cardiomyopathy
This trial uses a special heart MRI to better understand different types of hypertrophic cardiomyopathy (thick heart muscle). It may help doctors tell apart various forms of the condition and guide treatment.
Bologna, BOAges 18 years+ - NCT05886517Recruiting
Transcatheter aortic valve in patients too high-risk for surgery
This trial looks at placing a new aortic valve through the groin (transfemoral) without needing on-site heart surgery for people who are considered very high risk for standard open-heart valve surgery. It aims to measure early outcomes to see how safe and effective this approach is for frail or complex patients.
Acquaviva delle Fonti, BariAges 75–120 - NCT05629559RecruitingPhase 1/Phase 2
Study drug 4D-310 for Fabry disease with heart problems
This Phase 1/2 study tests how safe and potentially effective 4D-310 is for adults with Fabry disease who have heart involvement. It may help people who can’t tolerate standard treatments like enzyme replacement therapy (ERT) or migalastat, or who still have disease progression.
MelbourneAges 18–65 - NCT06823778Recruiting
Preventing irregular heartbeat after heart surgery with radiofrequency
This trial tests whether using radiofrequency energy to isolate a small area in the heart's left upper chamber can prevent a common irregular heartbeat (atrial fibrillation) after heart surgery.
Moscow, MoscowAges 18 years+ - NCT07372196Recruiting
Left bundle branch pacing after myectomy for hypertrophic cardiomyopathy
This trial is testing a new way to pace the heart (left bundle branch pacing) for people with hypertrophic cardiomyopathy who still have a dangerous heart rhythm problem after myectomy surgery. It aims to see if this pacing can reduce the risk of sudden cardiac death.
Novosibirsk, Novosibirsk OblastAges 18–75 - NCT07374263Recruiting
Do heart rhythm drugs pose risks in hospital?
This study looks at whether certain medications that can affect heart rhythm (QT-prolonging drugs) are linked to serious heart problems in adults who were hospitalized. It includes patients admitted to St. Joseph's Healthcare Hamilton or other GEMINI hospitals between 2017 and 2025.
Hamilton, OntarioAges 18 years+ - NCT07375602Recruiting
AI tool to predict complications after VSD closure in children
This study uses artificial intelligence to predict complications in children who have had a specific type of hole in the heart (called a perimembranous ventricular septal defect) repaired with a catheter-based procedure. The goal is to help doctors better identify which children might have problems after the procedure.
Shanghai, Shanghai MunicipalityAges Up to 18 years - NCT04595630Recruiting
Testing heart blood markers to spot early bypass blockage
This study checks whether heart blood tests can predict early blockage of a coronary bypass graft soon after bypass surgery. It may help doctors identify patients at higher risk sooner so they can monitor or treat problems earlier.
ZagrebAges 18 years+ - NCT07363993Recruiting
Heart flow and pumping in athletes vs. non-athletes
This study uses 3D ultrasound to see how the heart moves blood in people who exercise a lot versus those who do not. It could help understand how regular endurance training changes heart function.
AvignonAges 18–45 - NCT07370467Recruiting
MRI study for mitral & tricuspid valve repair
This study uses MRI scans to take detailed pictures of the heart before and after a valve repair procedure. It helps doctors better understand how these new, less invasive treatments affect heart function.
Milan, MilanAges 18 years+ - NCT07363772Recruiting
Mixed reality CPR training for adults
This trial tests whether mixed reality (a blend of real and virtual worlds) can teach cardiopulmonary resuscitation (CPR) to adults. It may help people who haven't taken a CPR class in the last year learn this lifesaving skill in a new way.
Seoul, Nowon-guAges 18–50 - NCT07354841Recruiting

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.
