Comparing high-dose vs. lower-dose opioid anesthesia for heart surgery
This trial compares two types of anesthesia during heart surgery: one that uses high doses of strong painkillers (opioids) and one that uses less opioids. The goal is to see which approach is safer and helps patients recover better.
BeijingAges 45–70 - NCT03469440Recruiting
Targeted oxygen monitoring during children’s heart surgery
This trial tests whether a goal-focused monitoring approach can help optimize oxygen levels in the blood during children’s heart surgery using a heart-lung machine. It may help clinicians adjust care more precisely during surgery.
São PauloAges Up to 14 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+ - 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+ - 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 - 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+ - 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 - 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+ - 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+ - 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+ - 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+ - NCT06136637Recruiting
Monitoring glycocalyx to predict complications after heart surgery
This study will see if measuring a substance in your blood (glycocalyx) can help doctors predict problems after heart surgery that uses a heart-lung machine. The goal is to improve care after surgery.
RouenAges 18–80 - 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+ - 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+ - NCT07324694Recruiting
Stable blood pressure during heart surgery and recovery
This study looks at how changes in blood pressure during heart surgery affect recovery. If you are having scheduled heart surgery with a heart-lung machine, you may be able to join.
Diyarbakır, DiyarbakırAges 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+ - 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+ - 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+ - 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+ - NCT06530641RecruitingPhase 4

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.
