Recruiting studies
- NCT06461377RecruitingPhase 4

Heart MRI and stress test after lung or esophagus surgery
This study uses a heart MRI with a stress medication to see how well the right side of the heart pumps after lung or upper digestive surgery. It may help doctors understand heart recovery after these operations.
Belfast, Northern IrelandAges 18 years+ - NCT06475547Recruiting
Inflammation and heart rhythm after heart surgery
This study looks at inflammation and how it relates to a heart rhythm problem called atrial fibrillation after heart surgery. It may help understand why some people develop this condition and how to better prevent it.
OdenseAges 18–99 - NCT06479876Recruiting

This study tests a home-based cardiac rehabilitation program for people with heart failure. It aims to help you become more active and manage your condition safely at home.
Nashville, TennesseeAges 18 years+ - NCT06481137Recruiting
Can heart electrical problems after TAVI get better?
This study looks at whether electrical problems in the heart that appear after a TAVI valve replacement can go away on their own. It will help doctors decide which patients might need a pacemaker and which might get better without one.
L'Hospitalet de Llobregat, BarcelonaAges 18 years+ - NCT06483087Recruiting
Animated education for kids before heart catheterization
This trial tests if watching an animated educational video before a scheduled heart catheterization can reduce anxiety and prevent complications. It is designed for children ages 6 to 12 who are having this procedure for the first time.
AmmanAges 6–12 - NCT05999721Recruiting
Nerve block for better breathing after heart surgery
This trial is testing a nerve block (a numbing injection) placed near the breastbone to see if it helps your lungs work better after heart surgery. If you are having planned heart surgery through a breastbone cut, you may be able to join.
Petah TikvaAges 18 years+ - NCT06491186Recruiting
Pulse check using ultrasound during cardiac arrest
This trial tests whether using an ultrasound on the groin area can quickly check for a pulse in people who have had a cardiac arrest outside the hospital. It may help emergency responders make faster decisions during resuscitation.
ViennaAges 18 years+ - NCT06493227Recruiting
Extended use of bleeding control drugs after heart surgery
This trial is for hospitals, not patients. Hospitals that do many open heart surgeries and whose doctors agree to use certain bleeding control drugs (fibrinolysis inhibitors) as per the study protocol can participate.
Saint PetersburgAges 18 years+ - NCT06510140Recruiting
Brain monitoring and frailty to predict confusion after surgery in older adults
This study tests if monitoring your brain waves during surgery and checking your frailty level can help predict whether you might become confused after surgery. It aims to improve care for older adults having major non-cardiac operations.
Saint-EtienneAges 75 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 - NCT06519747Recruiting
Detecting irregular heartbeat after non-heart surgery
This trial uses a monitoring device to check for a common but often overlooked irregular heartbeat (atrial fibrillation) after non-cardiac surgery. The goal is to detect and treat it early to prevent complications like stroke.
Hamilton, OntarioAges 18–120 - 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 - NCT06527105Recruiting
Sleep quality and recovery after heart surgery
This study looks at how your sleep affects recovery after planned heart surgery. Researchers want to see if better sleep leads to better outcomes, so they will track your sleep quality and health after the operation.
Kochi, KeralaAges 18–80 - 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 - 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+ - NCT06532825Recruiting
Nerve function test in advanced heart failure
This study looks at how the nervous system controls the heart in people with advanced heart failure. It may help doctors understand which patients are unlikely to recover, so they can plan the best care.
FrederiksbergAges 18 years+ - NCT06540521Recruiting
Heart device holter study for LBBAP patients
This study uses a special wearable device to record your heart's electrical signals. It is for people who have a pacemaker or CRT-P with a specific type of lead (LBBAP) and wants to check how well the therapy is working.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06541353Recruiting
Predicting heart function after a pulmonary embolism
This study uses heart signals and blood tests to predict how well your heart will recover over a year after a pulmonary embolism. It may help doctors tailor your care based on your personal risk.
Beijing, Beijing MunicipalityAges 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 - NCT06551714Recruiting
Movement techniques after first open heart surgery
This study tests special movement and breathing techniques to help people recover faster after their first open heart surgery. It focuses on improving health in the early days after surgery.
AnkaraAges 18–75 - NCT06554119Recruiting
Surgery for tricuspid valve leaks after prior heart surgery
This study looks at different surgeries for a leaky tricuspid valve that happened after earlier heart surgery. It may help doctors learn which approach works best for patients like you.
Guangzhou, GuangdongAges 16 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.

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,322 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.
