NantesAges Up to 17 years - NCT06786416Recruiting
Monitoring to prevent kidney injury after heart surgery
This trial is testing a new monitoring system that tracks blood flow and other vital signs during heart surgery to help prevent kidney damage afterward.

Renin levels in planned heart surgery patients
This study measures a substance in your blood (renin) before, during, and after planned heart surgery that uses a heart-lung machine. Researchers want to see if renin levels are linked to how well your body handles the surgery.
Rochester, MinnesotaAges 18 years+ - NCT06972082Recruiting
Ultrasound-guided treatment for kidney injury after heart surgery
This trial tests whether using ultrasound guidance (VEXUS) can help prevent or treat acute kidney injury after heart surgery. If you develop kidney problems in the first two days after your operation, you may be able to join.
Athens, KallitheaAges 18 years+ - NCT07077772Recruiting
Guiding fluid removal after heart surgery
This trial tests a method to guide how much fluid is removed after heart surgery using a urine salt test, to see if it helps patients recover better. If you are having planned heart surgery with a heart-lung machine, you may be able to join.
AmiensAges 18 years+ - NCT07116343RecruitingPhase 4
Pain relief through chest tube medication after heart surgery
This trial tests whether giving a numbing medicine (ropivacaine) through the chest tube after open-heart surgery can reduce pain. It may help patients recover more comfortably.
Saint PetersburgAges 18 years+ - NCT07164677Recruiting
Nerve block for pain after open-heart surgery
This study tests a nerve block (an injection near the back muscles) to see if it helps control pain after open-heart surgery. It might be a good option if you are having planned heart surgery through a cut in the middle of your chest.
SamsunAges 18–80 - NCT07539623RecruitingPhase 3
Pain relief with suzetrigine after heart or weight-loss surgery
This study tests whether suzetrigine, a new pain medication, can reduce the need for opioids (strong painkillers) after cardiac or bariatric surgery. The goal is to help patients manage pain with fewer opioid-related side effects.
New York, New YorkAges 18–85 - NCT06516432Recruiting
Nerve block and lactate in heart surgery
This study looks at how a nerve block near the breastbone (parasternal block) affects lactate levels in the blood for patients having heart surgery. It aims to understand if this pain management technique can help keep lactate levels normal during recovery.
Guadalajara, JaliscoAges 18 years+ - NCT07200726Recruiting
Brain inflammation and thinking after heart surgery
This study looks at whether brain inflammation during heart surgery may affect memory and thinking. It includes people aged 60 and older who are having planned heart surgery.
Genk, LimburgAges 60 years+ - NCT06786819Recruiting
Recovery app after heart bypass surgery
This study tests whether a smartphone app that helps you follow a recovery plan can shorten the time you need to stay in the hospital after coronary artery bypass (heart bypass) surgery. If you are scheduled for this surgery, have a smartphone, and are comfortable using it, this app might help you get home sooner.
São Paulo, São PauloAges 18 years+ - NCT07018856Recruiting
Can beginners detect collapsed lung after heart surgery via ultrasound?
This trial tests whether a beginner (like a nurse or trainee) can use an ultrasound to safely detect a collapsed lung (pneumothorax) after heart surgery when the chest tubes are removed. It could make care faster and safer for you.
Toronto, OntarioAges 18 years+ - NCT07032792RecruitingPhase 2
FEIBA versus plasma for bleeding after heart surgery
This trial compares two treatments for bleeding after heart surgery: a medicine called FEIBA (which helps blood clot) and fresh frozen plasma (a blood product). The goal is to see which works better as a first treatment for bleeding during recovery.
Manhasset, New YorkAges 18 years+ - NCT07075601Recruiting
Study of bacteria on heart valves during cardiac surgery
This study looks at the types of bacteria living on heart valves removed during surgery. Researchers want to learn more about these bacteria to better understand heart valve health and infections.
Toulouse, FranceAges 18 years+ - NCT07418242Recruiting
New markers for kidney risk after heart surgery
This study looks at whether certain blood or urine markers can predict kidney problems in people having high-risk heart surgery. The goal is to find early warning signs so doctors can take steps to protect your kidneys.
Shanghai, Shanghai MunicipalityAges 18–90 - NCT07484477Recruiting
Sitting less to improve heart and lung function after heart surgery
This study tests whether helping people sit less and move more after heart surgery can improve their breathing, heart function, and quality of life. If you're between 50 and 80 and have had heart surgery, this may help you recover better.
Peshawar, KPKAges 50–80 - NCT06059976Recruiting
Hypnosis during heart surgery recovery study
This study looks at the use of hypnosis during heart surgery to see how it affects recovery. If you are having major heart surgery and have already had hypnosis sessions before, during, or after the operation, you may be eligible to participate.
GrenobleAges 18 years+ - NCT07037043RecruitingPhase 3
Steroid medicines for high-risk heart surgery patients
This trial tests whether adding two common medicines, hydrocortisone and fludrocortisone, to standard care can help people who are at higher risk during planned heart surgery. It aims to see if this combination can reduce serious complications after surgery.
AmiensAges 18 years+ - NCT06747806Recruiting
A heart surgery biobank study
This study collects tissue samples from children and adults having heart surgery. The samples will help researchers learn more about heart conditions and improve future treatments.
Hyde Park, IllinoisAges Any age - NCT04880265Recruiting
Study heart rhythm changes after open-heart surgery
This study looks at how often and how long an irregular heartbeat (atrial fibrillation) happens after planned open-heart surgery. It aims to better understand the “burden” of this rhythm problem, which could help improve care for future patients.
Boston, MassachusettsAges 20–90 - NCT04754022Recruiting
Blood use during heart surgery in younger adults
This study looks at how much donated blood (blood products) is needed for younger adults during heart surgery that uses a heart-lung machine. It may help doctors choose safer, more appropriate blood-saving plans for people like you.
Portland, MaineAges 18–65 - NCT04284839RecruitingPhase 3
Blood thinner pills vs warfarin after heart surgery
This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.

Common questions
- Are there clinical trials for cardiac surgery?
- Yes. Clin2 currently lists 311 recruiting cardiac surgery 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 surgery 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 surgery 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.
