This study compares two methods of supplying blood to the brain during surgery on the main artery from the heart (aorta) and the aortic arch. It may help determine the safest way to protect the brain during cooling and surgery.
Durham, North CarolinaAges 18 years+ - NCT06208007Recruiting
Predicting heart failure with stiff arteries
This study looks at whether stiffer arteries can help predict a type of heart failure where the heart doesn't relax properly (HFpEF). It's for people who have risk factors like high blood pressure, diabetes, or being older, and who may have early signs of heart trouble.
Göttingen, Lower SaxonyAges 18 years+ - NCT06178510Recruiting
Breathing support after heart surgery
This trial tests a new way to help patients breathe after heart surgery. It compares standard breathing support with a new device that might help you recover faster in the ICU.
Vienna, State of ViennaAges 18–120 - NCT06172842Recruiting
Heart ultrasound study for electrical rhythm problems
This study uses special ultrasound techniques to look at how the heart works in people who have heart rhythm problems caused by electrical issues, not structural ones. It aims to better understand and treat these conditions.
GuangzhouAges Any age - NCT06165081Recruiting
Emergency care after cardiac arrest and short-term outcomes
This study looks at how care in the emergency room after a cardiac arrest affects short-term recovery. It may help doctors find better ways to treat patients whose hearts have stopped outside the hospital.
Hsinchu, Hsinchu CityAges 20 years+ - NCT06153888Recruiting
Heart strain during dialysis: a study on fluid removal
This study looks at how quickly fluid is removed during dialysis affects the heart. It may help find safer ways to manage fluid removal for people on hemodialysis.
UmeåAges 18 years+ - NCT06128330RecruitingPhase 4
Bedside test for bleeding prevention drug in heart surgery
This study tests a quick bedside measurement of how well the drug tranexamic acid works to prevent bleeding during heart surgery. It may help doctors give the right dose to reduce blood loss.
BernAges 18–90 - 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+ - NCT07305389Recruiting
Music and exercise in cardiac rehab
This study tests how different types of music affect your mood during exercise in a cardiac rehabilitation program. It may help make your rehab workouts more enjoyable.
GenevaAges 50–75 - NCT05738408Recruiting
Remote smoking help for hospitalized heart patients
This trial tests a phone-based (remote) smoking quit program for people hospitalized for a recent heart-related event. It may help you quit smoking by offering support when you’re in the hospital and afterward.
Burlington, VermontAges 18 years+ - NCT07673536Recruiting
Heart transplant monitoring with extracellular vesicles
This study uses tiny particles called extracellular vesicles (which cells release) to check for signs of organ rejection after a heart transplant, aiming for a safer and less invasive alternative to biopsies.
Berlin, State of BerlinAges 18 years+ - NCT04180085RecruitingPhase 2
Belatacept to protect kidneys in heart transplant patients
This trial studies whether belatacept can be used after a heart transplant to help protect kidney function over time. It focuses on people who already have (or are at risk for) worsening kidney function after transplant, while avoiding those with certain infections or rejection concerns.
BordeauxAges 18 years+ - NCT05481723RecruitingPhase 3
Lung ultrasound to guide fluid and blood pressure during surgery
This Phase 3 study tests whether using a lung ultrasound scan during surgery can better guide blood pressure and fluid needs. It may help stabilize patients during long operations and reduce complications related to poor circulation or fluid balance.
AmiensAges 18 years+ - NCT05944146Recruiting
Tests two methods for measuring heart blood flow during surgery
This trial compares a neck ultrasound test (carotid Doppler) with a heart monitoring method (thermodilution) to see if they give consistent blood-flow readings. It may help clinicians measure circulation more reliably in people having heart surgery.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT04332692Recruiting
Check if a lung ultrasound helps evaluate discharge after heart failure
This study looks at whether doing lung ultrasounds can better assess people right before they leave the hospital after an acute heart failure flare. It may help doctors decide when someone is ready for discharge and tailor care to reduce risk after leaving.
Vandœuvre-lès-NancyAges 18 years+ - NCT05941013Recruiting
Ultrasound-check breathing tube during heart procedures
This feasibility study tests a special breathing tube that can be checked with ultrasound during a planned heart catheter procedure under general anesthesia. It may help doctors confirm the tube is in the right place more easily and safely, before and after the procedure.
Ann Arbor, MichiganAges 6 months–3.5 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+ - NCT07611890RecruitingPhase 4
Comparing two medications to reduce heart stress during cardiac surgery
This trial tests whether dexmedetomidine or lignocaine better prevents dangerous heart-rate and blood-pressure changes when a breathing tube is placed during heart surgery. If you're having cardiac surgery and are at high risk for heart complications, this study may help protect your heart during the procedure.
Rawalpindi, Punjab ProvinceAges 18–65 - NCT07677319Recruiting

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,308 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.
