Recruiting studies
- NCT06705855Recruiting

Blood management for cardiac surgery patients
This trial studies a program to manage blood levels before, during, and after heart surgery. It may help reduce the need for blood transfusions and improve recovery.

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+ - NCT06371976Recruiting
Stress hormone system study after heart surgery
This study looks at how your body's stress hormone system (the HPA axis) works after heart surgery if you develop vasoplegic syndrome (a serious drop in blood pressure). The goal is to understand if giving extra steroids might help. If you are scheduled for heart surgery with a heart-lung machine, you may be able to join.
Paris, Île-de-France RegionAges 18 years+ - NCT06279793RecruitingPhase 2
Fish oil for recovery after high-risk heart surgery

This trial tests whether giving iron through a vein after heart surgery can help fix low iron levels and improve recovery. It is for people who have iron deficiency (with or without anemia) before their planned heart surgery.
Kingston, OntarioAges 18 years+ - NCT06251713Recruiting
Fluid removal guided by VeXUS score after heart surgery
This trial tests if using a special ultrasound score (VeXUS) to guide fluid removal can improve recovery in patients with acute kidney injury after heart surgery. It compares this approach to standard care to see if it leads to better outcomes.
Bron, BronAges 18–85 - NCT05879432RecruitingPhase 2
Peptide treatment to prevent or lessen kidney injury after heart surgery
This Phase 2 trial tests an LSALT peptide given around the time of “on-pump” heart surgery to help prevent or reduce acute kidney injury (a sudden drop in kidney function). It may help people who are at higher risk for kidney injury during or after surgery.
Calgary, AlbertaAges 18 years+ - 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 - NCT04241328Recruiting
Cardiac surgery registry for patients who used a Medtronic device
This study tracks patients who had cardiac surgery using a specific Medtronic heart-surgery device. It mainly collects real-world data to help understand outcomes, and you may be included if you give consent and are not in another device/drug study that could affect the results.
ViennaAges Any age - 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 - 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+ - 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+ - NCT07385092Recruiting
Continuous monitoring after non-cardiac surgery
This trial compares continuous vital sign monitoring with standard spot checks for patients recovering from non-cardiac surgery. It aims to see if constant monitoring can improve safety and outcomes.
Hamburg, Free and Hanseatic City of HamburgAges 45 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 - NCT07770269Recruiting
Heart function and anesthesia depth during heart surgery
This study checks how well the heart works and how deep the anesthesia is during planned heart surgery where a heart-lung machine is used. It aims to improve safety and outcomes for patients.
ThessalonikiAges 18 years+ - NCT05166954Recruiting
Bariatric surgery and heart function in people with high blood pressure
This study looks at whether bariatric (weight-loss) surgery improves heart function in people who have high blood pressure. You may be able to join if you’re already a bariatric surgery patient at the study hospital and meet the health and medication criteria.
Beijing, Beijing MunicipalityAges 17–70 - 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 - NCT05833828Recruiting
Testing blood-pressure hormone changes during bypass surgery
This study looks at how a blood-pressure hormone system (RAAS) changes during coronary artery bypass surgery. It may help researchers understand better how to manage blood pressure and heart stress around the time of surgery.
BerlinAges 18 years+ - NCT04284839RecruitingPhase 3
Blood thinner pills vs warfarin after heart surgery
This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.
Fitzroy, VictoriaAges 18 years+ - NCT06956911Enrolling by invitation
Low-resistance exercise with blood flow restriction after heart surgery
This trial tests if gentle arm exercises with a special blood pressure cuff can help men recover their lung function after heart surgery. It may be an option for those who are stable and ready to follow simple instructions.
Cairo, Cairo GovernorateAges 45–60 - NCT06115759Recruiting
Recovery and activity study after open-heart surgery

Common questions
- Are there clinical trials for cardiac surgery patients?
- Yes. Clin2 currently lists 382 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.
