Recruiting studies
- NCT07077824Recruiting
Nerve block to reduce artery catheter complications in heart surgery
This trial tests whether a nerve block (stellate ganglion block) can reduce complications from placing an artery catheter during heart surgery. It is for people with weak heart function (EF below 35%) or severe lung hypertension who are expected to have a long surgery.
CairoAges 18 years+ - NCT05817929Recruiting
Angiopoietin levels and outcomes after heart bypass surgery
This study looks at how a blood protein called angiopoietin relates to recovery and complications after heart surgery that uses a heart-lung machine. If you’re having scheduled heart bypass-type surgery, your team may take blood samples to see whether these levels can help predict outcomes.
AmiensAges 18 years+ - NCT07013591RecruitingPhase 2
Nicotinamide mononucleotide for heart surgery recovery
This study tests whether taking nicotinamide mononucleotide (a dietary supplement) before and after heart surgery can help reduce complications and improve recovery. It is for people having heart bypass or valve surgery who are at higher risk of problems after surgery.
Boston, MassachusettsAges 18 years+ - NCT06986187Recruiting
Predicting difficult airways in heart surgery patients
This study measures how often difficult airways occur during heart or blood vessel surgery and builds a way to predict them beforehand. It may help your care team prepare for safer airway management during your procedure.
AnkaraAges 18 years+ - NCT06970925RecruitingEarly Phase 1
Iron supplement after heart surgery study
This trial tests whether a special iron supplement (Sucrosomial® Iron) helps patients recover from heart surgery better than standard care. It is for people who have low iron or anemia after their planned heart surgery.
Englewood, New JerseyAges 18 years+ - NCT06794697Recruiting
Does admission day affect anxiety before heart surgery?
This study looks at whether the day you are admitted to the hospital for planned heart surgery affects your anxiety levels before the operation. The goal is to help hospitals schedule admissions in a way that lowers stress for patients.
RennesAges 18 years+ - NCT06705855Recruiting
Predicting kidney injury after heart surgery using skin sensors
This study tests whether a special light-based monitor on your skin (near your kidney and arm) can predict kidney injury after heart surgery. It aims to help doctors protect your kidneys during and after the procedure.
Salt Lake City, UtahAges 18 years+ - NCT06279793RecruitingPhase 2
Fish oil for recovery after high-risk heart surgery
This trial tests if giving fish oil through a vein before and after heart surgery can help patients recover faster. It is for people who have a high risk of complications during surgery.
AugsburgAges 18 years+ - NCT07852390Recruiting
Pacing after heart surgery in children
This study tests whether using a pacemaker after heart surgery helps children's hearts recover and pump more efficiently. It is for children under 12 years old who are having heart surgery at Lurie Children's Hospital.
Chicago, IllinoisAges Up to 12 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+ - 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+ - 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+ - 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+ - 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+ - 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 - 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 - NCT01258231Recruiting
Genetic test to predict risks after heart surgery
This study looks for genetic (DNA) clues that may help predict side effects or complications after heart surgery. If you join, your genome information may be used to understand who is at higher risk and why.
Boston, MassachusettsAges 20–90 - NCT06396767Recruiting
Breathing test before heart surgery to predict lung problems
This study uses a simple breathing test before scheduled heart surgery to see if it can help predict breathing or lung complications after the operation. The results may help doctors identify patients who need extra support during recovery.
London, OntarioAges 19–99 - 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+ - 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 - NCT06625892Recruiting
Fear of movement after heart surgery
This study looks at why some people fear moving after heart surgery and tests a program to help them overcome that fear. It aims to improve recovery and quality of life.

Huperzine A to reduce confusion after non-heart surgery
This trial studies whether a medicine called huperzine A can reduce “postoperative delirium,” which is sudden confusion after surgery, in older adults. It focuses on people having non-heart surgery under general anesthesia for at least two hours.

Common questions
- Are there clinical trials for cardiac surgery?
- Yes. Clin2 currently lists 295 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.
