Seattle, WashingtonAges 18 years+ - NCT06557616Recruiting
CoolCryo system for treating atrial fibrillation during mitral valve surgery
This trial tests a new tool called CoolCryo that freezes heart tissue to treat atrial fibrillation while you have mitral valve surgery. If you are already having this surgery and also have AF, this device could correct both problems at once.
BydgoszczAges 18 years+ - NCT06566196Recruiting
Heart exercise testing for congenital heart disease
This study tests how well your heart pumps during exercise while you are undergoing a heart catheter procedure. It may help doctors better understand your heart function and guide your treatment.
Rochester, MinnesotaAges 18 years+ - NCT06350994Recruiting
Early Heart Check After CAR-T Cell Treatment
This study checks your heart function early after CAR-T cell cancer treatment. It uses a quick heart ultrasound to look for changes soon after the infusion.
ParisAges 18 years+ - NCT06546137Recruiting
Registry for inherited heart conditions in Brazil
This study is building a national registry in Brazil to learn more about inherited heart conditions and improve care. If you have a family-related heart disease, you may be able to join and help advance cardiovascular healthcare.
Rio Branco, AcreAges Any age - NCT06532890Recruiting
Using microRNAs to personalize heart transplant medicines in children
This study is looking at heart transplant children (up to age 18) to see if measuring tiny molecules called microRNAs in the blood can help doctors personalize anti-rejection medicines. It aims to improve how we prevent rejection while reducing side effects.
Aurora, ColoradoAges Up to 18 years - NCT06526533RecruitingPhase 3
Red blood cell transfusion thresholds for ECMO patients
This trial is testing whether a higher or lower threshold for red blood cell transfusions is better for people on ECMO (a heart-lung machine). It aims to find the safest way to manage transfusions during ECMO treatment.
Camperdown, New South WalesAges Any age - NCT06530433Recruiting
Community first responder app trial in Singapore
This trial tests a new way to send trained community first responders to medical emergencies using the myResponder® app. It aims to see if faster help from nearby volunteers can improve outcomes for people in need.
Singapore, SigaporeAges 21 years+ - NCT06529575Recruiting
How skin color affects pulse oximeter accuracy in children
This study checks if a child's skin color affects how well a pulse oximeter (a small clip on the finger that measures oxygen in the blood) works. It involves children having a heart catheterization, where doctors can directly measure oxygen levels, to see if the pulse oximeter gives the same reading.
New York, New YorkAges 4 weeks–18 years - NCT05868239Recruiting
Testing an aerosol box during CPR emergencies
This study tests whether using an aerosol “box” during cardiopulmonary resuscitation (CPR) during an emergency improves safety and care. It’s mainly aimed at trained healthcare staff who can perform required tasks during CPR.
Los Angeles, CaliforniaAges 18–60 - NCT05476991RecruitingPhase 3
Low-dose colchicine plus ticagrelor to prevent repeat stroke
This Phase 3 study tests whether low-dose colchicine added to ticagrelor (a blood-thinning medicine) helps prevent another ischemic stroke in people whose first stroke was caused by clogged arteries. It aims to lower the risk of repeat stroke after recovery from a recent event.
Paris, ParisAges 18 years+ - NCT06510894Recruiting
Testing a drug to improve heart imaging
This study tests if a drug can help suppress sugar uptake in the heart for clearer imaging. It may help researchers understand how to better see heart problems.
Philadelphia, PennsylvaniaAges Any age - NCT06511505Recruiting
Testing AI to find hidden heart conditions from ECGs
This study uses an AI tool to look at your ECG (a simple heart test) to help find early signs of atrial fibrillation (an irregular heartbeat) or structural heart disease (changes in heart structure). It aims to see if the AI can help doctors catch these conditions sooner, even in people who don't yet have symptoms.
Chicago, IllinoisAges 40 years+ - NCT05094843Recruiting
Mini-invasive surgery for lung cancer and heart rhythm changes
This study looks at how lung cancer surgery affects the heart’s electrical signals and stress response, using heart tracing tests (ECG) around the time of surgery. It may help doctors better understand and monitor heart risks in people having curative, minimally invasive lung cancer surgery.
Tampere, PirkanmaaAges 18 years+ - NCT06464315Enrolling by invitation
VT Ablation Guided by Scar Tissue Only
This trial tests a new approach to treating a dangerous heart rhythm called ventricular tachycardia (VT) in people with scarred heart muscle. The goal is to use only the scarred area to guide the ablation procedure, which may make it safer and more effective.
San Diego, CaliforniaAges 18–90 - NCT06460519Recruiting
Comparing wrist and groin blood pressure in shock patients
This study looks at how blood pressure readings differ between the wrist and the groin in people with severe low blood pressure (shock) who are not recovering from heart surgery. It aims to help doctors better understand and treat shock by comparing these two measurements.
BronAges 18–99 - NCT06455384Recruiting
Studying a digital tool for genetic testing services
This trial tests a new online tool called the Genetics Navigator, which helps people access genetic testing services more easily. If you or your child have been referred for genetic testing at Mount Sinai Hospital or SickKids in Toronto, this study may help you manage the process online.
Toronto, OntarioAges 18 years+ - NCT06455514RecruitingPhase 1
Magnesium to protect the brain after cardiac arrest
This study tests if giving magnesium soon after a cardiac arrest can protect the brain and improve recovery. It is for adults who have been brought back to life after a heart stoppage.
New York, New YorkAges 18–85 - NCT06444425Enrolling by invitation
AI test for heart function using ultrasound
This trial uses artificial intelligence to analyze heart ultrasound images. It aims to see if AI can detect heart function better than standard methods. You may be eligible if you are a cardiology patient having an ultrasound and can return for extra blood pressure checks.
Yiwu, ZhejiangAges 18 years+ - NCT04950218Recruiting

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.
