Recruiting studies
- NCT06918301Recruiting
Comparing heart measurements in cardiac surgery patients
This trial compares three ways to measure how well your heart pumps blood after cardiac surgery. It uses a standard catheter and two newer monitors to see which is most accurate.
KarlsburgAges 18 years+ - NCT07417462Recruiting
Pain relief after heart surgery to help you recover faster
This trial tests a combination of pain medicines given during cardiac surgery to reduce pain and speed up recovery. It may help patients who are having a first-time bypass surgery through a standard breastbone incision.
AsyutAges 40–60 - NCT04389463Recruiting
Study of heart surgery outcomes during COVID-19
This study looks at how people do after heart or chest surgery when they test positive for COVID-19. It may help doctors understand risks and outcomes for surgical patients during the pandemic.
NantesAges 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+ - NCT07640646Recruiting
Heart Surgery and Long-Term Pain: A Patient Survey
This study asks patients who had heart surgery in the past year about any ongoing pain or discomfort in the surgical area. The goal is to understand how common long-term pain is after heart surgery and how it affects daily life.
Leuven, Vlaams BrabantAges 18 years+ - NCT06613178RecruitingPhase 4
IV acetaminophen for heart surgery recovery
This trial tests if giving acetaminophen (Tylenol) through a vein after heart surgery can help patients recover better. You may be a good fit if you are having planned heart surgery that is not an emergency.
Vancouver, British ColumbiaAges 18 years+ - NCT06959121Recruiting
Treating AFib during open-heart surgery with a new device
This trial tests a new device used during open-heart surgery to treat atrial fibrillation (AFib) by delivering tiny, fast electrical pulses to the heart tissue. It is for people who are already having heart surgery and want to also treat their AFib at the same time.
St. Helena, CaliforniaAges 18–85 - NCT06874465Recruiting
Aortic valve replacement study for severe stenosis
This study tracks patients getting a new heart valve (transcatheter aortic valve implantation) for severe aortic stenosis. It aims to understand long-term outcomes and safety in a real-world registry.
AstanaAges 18 years+ - NCT04073420Recruiting
Cardiac surgery registry to track Medtronic device outcomes
This registry collects real-world information from people who have had—or plan to have—an eligible Medtronic cardiac surgery device. It aims to better understand how these treatments do over time and help guide future care.
Marietta, GeorgiaAges Any age - 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 - NCT04556188Recruiting
Study to improve cardiac surgery services for rheumatic heart disease
This study looks at whether building a better, sustainable cardiac surgery service can reduce the burden of rheumatic heart disease. It focuses on patients who need cardiac surgery at a specific hospital during a training and research program.
Addis AbabaAges 14 years+ - NCT03360838Recruiting
Prediction test for confusion after heart surgery in older adults
This study uses a short, self-answered thinking test before elective heart surgery to help predict who may develop confusion afterward. The goal is to improve early identification and care planning for patients at higher risk.
BaselAges 60 years+ - NCT03209674Recruiting
Registry tracking outcomes after heart and chest surgery
This is a registry that collects information from people who have heart or chest (thoracic) surgery. It may help doctors understand what improves outcomes after surgery, but it usually does not test a new drug.
Neuilly-sur-Seine, Île-de-France RegionAges Any age - NCT07082283Recruiting
Atrial pacing and heart function after cardiac surgery
This study looks at how a short burst of electrical pacing to the upper chambers of the heart affects blood flow and heart function after cardiac surgery. It may help doctors find better ways to support recovery.
BeirutAges 18 years+ - NCT05833048Recruiting
Pain-relief nerve block during cardiac surgery
This study tests whether a numbing “nerve block” placed in the rectus sheath area can reduce pain for people having certain heart surgeries with chest tubes. If you qualify, it may help your comfort during recovery, but it also depends on how suitable you are for local anesthesia.
New York, New YorkAges 18–85 - NCT04973579Recruiting
Stent plus heart surgery for high risk carotid patients
This trial looks at whether doing carotid artery stenting at the same time as heart surgery is safe and effective for people at high risk of stroke around the time of surgery. It targets people with significant carotid narrowing who also need heart surgery for specific heart problems.
KrakowAges 18 years+ - NCT06144125RecruitingPhase 4
Blood management trial for heart surgery patients
This trial compares two treatments (prothrombin complex concentrate and fresh frozen plasma) for managing bleeding during heart surgery. It aims to find which approach works better and is safer for patients.
Seoul, SeoulAges 20–75 - NCT05786274Recruiting
Predicting stroke risk after heart surgery using heart signals and MRI
This study looks at ways to predict harmful brain and blood-vessel side effects after heart surgery. It may help doctors identify higher-risk patients sooner so they can monitor them more closely.
San Donato Milanese, MilanAges 18 years+ - NCT06772025Recruiting
Understanding kidney injury after heart surgery with heart-lung machine
This study looks at why some people develop kidney damage after heart surgery that uses a heart-lung machine. It aims to help doctors better predict and prevent this complication.
Bad Oeynhausen, North Rhine-WestphaliaAges 18 years+ - NCT07164833RecruitingPhase 2
Testing a drug to prevent kidney injury after heart surgery
This study tests a new medicine, BX-001N, to see if it can prevent kidney damage during and after heart surgery for aortic disease. It is for people with moderate kidney problems who are having planned surgery that stops the heart briefly.
DaeguAges 19–90 - NCT07532174Recruiting
Blood-Cleaning Device During Heart Surgery
This trial tests a special blood-filtering device (Efferon LPS) used during heart surgery to reduce inflammation and improve recovery. The device removes harmful substances from your blood during the operation.
BarnaulAges 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+ - 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+ - NCT04331249Recruiting
Monitoring heart device during and around your procedure
This trial looks at how to manage and check implanted heart devices (pacemakers/defibrillators) during and around a planned procedure. It may help teams improve safety and decision-making during surgery or catheter procedures.

Common questions
- Are there clinical trials for cardiac surgery?
- Yes. Clin2 currently lists 310 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.
