Milan, MilanoAges birth–17 years - NCT07744009Recruiting
Awake breathing support for heart valve surgery
This trial tests a new anesthesia method that lets you breathe on your own during heart valve surgery, instead of using a breathing tube. It aims to see if this approach is safer and helps you recover faster than standard anesthesia.
Guangzhou, GuangdongAges 18 years+ - NCT07746505Recruiting
Remimazolam vs midazolam for anesthesia in older adults
This study compares two sedative medicines used to start general anesthesia in patients 65 and older having non-cardiac surgery. The goal is to see which one is safer and works better for older patients.
HangzhouAges 65 years+ - NCT07746336RecruitingPhase 4
Guiding heart ablation with 3D heart mapping
This trial tests a new heart-mapping technique to help doctors treat a fast heart rhythm caused by heart disease. It might improve the precision of the procedure, making it safer and more effective for patients with this condition.
BarcelonaAges 18–99 - NCT06622915Recruiting
Heart health in kids with kidney condition
This study looks at how different types of nephrotic syndrome affect heart function in children. It may help doctors understand the heart risks in kids who need steroids for a long time compared to those whose condition doesn't respond to steroids.
SohagAges 2–14 - NCT07738107RecruitingPhase 1/Phase 2
Study of ATR 1072 for PRKAG2 syndrome
This trial tests a new medicine called ATR 1072 for people with PRKAG2 syndrome, a genetic heart condition. It aims to see if the drug is safe and can help manage symptoms.
Kansas City, MissouriAges 18–65 - NCT07733960Recruiting
Pacing system study for heart pacing therapy
This trial tests a new pacing system designed to improve how pacemakers work. It may help people who need a pacemaker with left bundle branch area pacing.
Madurai, Tamil NaduAges 18 years+ - NCT07727057Recruiting
New catheter treatment for dangerous heart rhythm problems
This study tests a new catheter-based treatment for people with certain types of very fast or extra heartbeats that come from the lower chambers of the heart. The catheter uses a special energy to stop the abnormal beats and might help if you have had symptoms despite other treatments.
LinzAges 18 years+ - NCT07729891Recruiting
Vital sign monitoring after urological surgery
This study tests a system that constantly watches your vital signs (like heart rate and blood pressure) after urological surgery, to catch problems early. It's for people who are not expected to need the Intensive Care Unit after their operation.
Parma, ParmaAges 18 years+ - NCT07726056Recruiting
Heart ablation in athletes with atrial fibrillation
This trial tests if a heart procedure (cardiac ablation) helps endurance athletes who have atrial fibrillation (an irregular heartbeat) perform better in sports. Athletes will track their training data before and after the procedure to see if their performance improves.
MelbourneAges 18–80 - NCT07724262Recruiting
Testing the Argos System to measure heart blood flow
This trial is testing a new system called Argos to see if it can measure how much blood your heart pumps more easily than current methods. It is for patients already in the ICU who need a quick change in fluids or blood pressure medicine.
Le Kremlin-BicêtreAges 18 years+ - NCT04844944Recruiting
Heart registry for adults with heart failure, CAD, or atrial fibrillation
This is a hospital-based study that collects standardized information about adults with specific heart conditions—heart failure, coronary artery disease, or atrial fibrillation. It may help doctors and researchers better understand these diseases and improve future care.
BerlinAges 18 years+ - NCT04344912Recruiting
Study of COVID-19 effects on heart emergency care
This study looks at how the COVID-19 outbreak affected care for people admitted to the cardiac intensive care unit. It may help hospitals improve how they plan and respond during major outbreaks.
ParisAges 18 years+ - NCT04416958Recruiting
Pacemaker or defibrillator pacing strategy to reduce heart timing issues
This study looks at a pacing approach for people with a pacemaker or ICD (defibrillator) to help prevent the heartbeats from becoming out of sync. It may be useful if your implant team is trying to reduce pacing-related “timing” problems in the heart.
Fürth, BavariaAges 18 years+ - NCT07713121Recruiting
Keeping blood pressure up during surgery to prevent confusion in older adults
This trial tests whether keeping blood pressure at 85 mmHg or higher during surgery can reduce confusion (delirium) after surgery. It is for older adults with high blood pressure who are having non-cardiac surgery.
HamburgAges 65 years+ - NCT07711821Recruiting
Heart failure screening in primary care for older adults
This trial is testing a simple screening tool to find early signs of heart failure in people aged 50 or older, especially those with risk factors like diabetes or high blood pressure. If you're at risk, this could help catch heart problems sooner.
AmadoraAges 49 years+ - NCT06055751Recruiting
Heart rhythm monitoring after aortic valve replacement
This trial studies people who had a heart valve procedure called TAVI and later had a heart rhythm problem. You will get a tiny heart monitor placed under your skin to track your heart rhythm over time and help doctors understand how common these problems are.
Kansas City, MissouriAges 18 years+ - NCT07700459Recruiting
Exercise prehabilitation for congenital heart surgery
This study tests whether a supervised exercise program before heart surgery can help adults with congenital heart disease recover better. You would join an exercise class 2–3 times a week for several weeks leading up to your operation.
LiverpoolAges 18 years+ - NCT07699016Recruiting
Hemostatic agent use in heart and blood vessel surgery
This trial surveys surgeons about how they use hemostatic agents (medications that stop bleeding during surgery). It aims to understand current practices and improve patient safety.
Milan, MIAges 18 years+ - NCT07703033Recruiting
Heart Impact Study for Breast Cancer Radiotherapy
This study looks at how information about the heart may affect treatment decisions for people receiving radiation therapy for breast cancer. It aims to help reduce heart-related side effects from treatment.
CopenhagenAges 35 years+ - NCT04913727Recruiting
Testing heart scan predictions after mitral valve repair
This trial studies severe secondary mitral valve leaking and uses heart imaging to predict how well the heart and symptoms improve after a less-invasive valve procedure. It may help doctors better forecast who benefits most from this repair.

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.
