Tracking complications after heart surgery in adults
This study looks at how often and why complications happen after heart surgery, using information from the hospital stay. It may help improve care by understanding postoperative risks and outcomes.
ParisAges 18 years+ - NCT06175650Recruiting
Female-focused recovery plan after heart surgery
This study looks at how to improve recovery after heart surgery, especially for women. It reviews medical records from people who had heart surgery in the past or will have it in the next few years at two hospitals in Amsterdam.
Amsterdam, North HollandAges 18 years+ - NCT06109155RecruitingPhase 4
Comparing medications to reduce bleeding in heart surgery
This trial tests two medicines—ACT (a blood thinner) and tranexamic acid (a medicine to reduce bleeding)—to see which is better at controlling bleeding during heart surgery. It is for adults having planned heart surgery with a heart-lung machine.
TaichungAges 18 years+ - NCT07851350Recruiting
Preparing for major surgery with a personalized fitness plan
This study offers a program to help you get physically and mentally ready for major surgery. It tests whether a personalized preparation plan improves recovery and reduces complications.
Varese, VAAges 18 years+ - NCT07798011Recruiting
Faster breathing tube removal after pediatric heart surgery
This study compares two ways of helping children wake up and breathe on their own after minimally invasive heart surgery. One group gets a drug to quickly reverse the muscle relaxant, while the other group waits for it to wear off naturally. The goal is to see which method allows a safer, earlier breathing tube removal.
HanoiAges 2–18 - NCT06554925Recruiting
Sex differences in cardiac surgery patients
This study looks at how men and women may differ in their experiences and outcomes after heart surgery. It may help doctors provide better care for all patients.
Amsterdam, North HollandAges 18 years+ - NCT06469515Recruiting
Thinking recovery after heart surgery in older adults
This study looks at how older adults recover their thinking and memory skills after heart surgery. You may be asked to do simple computer or paper tests to see how your brain heals.
GothenburgAges 65 years+ - NCT07627009Recruiting
Arm Exercises With and Without Deep Breathing After Heart Surgery
This study tests whether doing arm exercises combined with deep breathing helps recovery after open-heart surgery. Researchers want to see if breathing exercises during movement improves lung function and overall healing in patients recovering in the ICU.
İzmit, KocaeliAges 18 years+ - NCT05778981Recruiting
Study of blood-vessel health during non-heart surgery
This study looks at how blood-vessel function changes around the time of non-heart surgery, especially in people 45 and older. It may help doctors better understand risks and recovery related to blood-vessel stress during hospitalization.
Independencia, Santiago MetropolitanAges 45 years+ - 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 - NCT07518524Recruiting
Fast Recovery After Heart Valve Surgery
This trial compares two recovery approaches after heart valve surgery: one that wakes you up very quickly in the operating room, and one that's slightly less aggressive. Both use techniques that avoid large chest incisions. The goal is to see which approach gets you breathing on your own sooner and helps you recover faster.
Legnano, ItalyAges 18 years+ - NCT07513974Recruiting
Pain sensitivity test to predict opioid needs in heart surgery
This study measures how sensitive you are to pain using a special device, then tracks how much pain medication you need during heart surgery. The goal is to see if pain sensitivity can predict opioid requirements and help doctors customize pain control for you.
Brussels, AnderlechtAges Any age - NCT06632613RecruitingPhase 2
Trial of ENN0403 to prevent kidney injury after heart surgery
This study tests a new drug (ENN0403) given during heart surgery to see if it prevents acute kidney injury—a sudden drop in kidney function. The trial is for people who are already at higher risk due to their specific heart surgery and other health factors.
ShanghaiAges 18–85 - 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.
San Donato Milanese, MilanoAges 18 years+ - NCT07385170Recruiting
Glucose monitor accuracy during heart surgery
This trial checks how well a continuous glucose monitor works during heart surgery. It aims to help manage blood sugar levels more safely in the operating room.
SeoulAges 19 years+ - NCT06530641RecruitingPhase 4
Comparing heart protection solutions during major heart surgery
This trial compares two types of cardioplegia (a solution that stops your heart during surgery) to see which one leads to better outcomes. It is for adults undergoing major heart surgery with a heart-lung machine.
Madrid, MadridAges 18 years+ - NCT06660602Recruiting
Brain function check before and after heart surgery
This study checks how well your brain works before and after heart surgery. It uses safe tests like a CT scan and an EEG to see if surgery affects brain function.
BeijingAges 18–80 - NCT06754709Recruiting
Protein Changes in Children Having Heart Surgery
This study looks at a specific protein change in blood and heart tissue of children having heart surgery with a heart-lung machine. The goal is to understand how this protein might affect recovery.
NantesAges Up to 17 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 - NCT07163234Recruiting
Safety of a groin artery tube for heart surgery
This study is testing a special tube (cannula) placed in the groin artery during heart surgery to connect a heart-lung machine. It's for people who are scheduled for planned heart surgery and may be helped by this refined device.
MassyAges 18 years+ - NCT06137547Recruiting
Preventing low blood pressure during heart surgery with HPI
This trial tests a new method (called HPI) to prevent dangerously low blood pressure during planned heart surgery. It is for adults having bypass surgery or valve surgery, but not for those with certain heart rhythm problems or needing emergency surgery.
TaipeiAges 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+ - 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+ - 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.

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.
