Vasopressin vs. Noradrenaline for low blood pressure after heart surgery
This trial compares two medications, vasopressin and noradrenaline, to see which one works better at raising blood pressure in patients who develop dangerously low blood pressure (vasoplegic syndrome) within the first day after heart surgery. The goal is to find the safest and most effective treatment to stabilize blood pressure and help recovery.
São PauloAges 18 years+ - NCT06952907Recruiting
Arm vs. leg artery pressure monitoring in heart surgery
This study compares measuring blood pressure through an arm artery (radial) versus a leg artery (femoral) during heart surgery that uses a heart-lung machine. The goal is to see which method works better and is safer for patients.
BesançonAges 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+ - 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+ - NCT06984276Recruiting
Nerve blocks for pain relief in children having heart surgery
This study compares two different ultrasound-guided numbing injections (pectoral nerve block vs. transverse thoracic plane block) to see which provides better pain control for children aged 6 months to 7 years undergoing heart surgery through a chest incision with a heart-lung machine.
CairoAges 6 months–7 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+ - NCT07024420Recruiting
Sigh breathing during heart surgery with heart-lung machine
This study tests if adding occasional deep breaths (sighs) during heart surgery helps patients recover better after using the heart-lung machine. It is for people having planned (not emergency) heart surgery.
Nanjing, JiangsuAges 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+ - NCT07059715Recruiting
Studying blood flow during heart surgery for vasoplegia risk
This study looks at blood flow in small and large vessels during heart surgery to understand and predict vasoplegic syndrome, a dangerous drop in blood pressure. It may help find patients at risk and improve their care.
ParisAges 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+ - 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+ - 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+ - NCT07081009Recruiting
Heart injury after planned back surgery study
This study is looking at whether patients having planned lower back surgery experience any heart stress afterward. It aims to understand how common this is and what might help protect the heart.
AnkaraAges 18 years+ - NCT07163234Recruiting
Safety of a groin artery tube for heart surgery

Common questions
- Are there clinical trials for cardiac surgery patients?
- Yes. Clin2 currently lists 385 recruiting cardiac surgery patients 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 patients 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 patients 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.
