Recruiting studies
- NCT07267546Recruiting
Study on heart-lung machine fluid and its effects in heart surgery
This study looks at how the fluid used to fill the heart-lung machine affects the body's chemistry and recovery in patients having heart surgery. It may help doctors choose the best fluid for better outcomes after bypass surgery.
LundAges 18 years+ - NCT07239648Recruiting
Heart surgery and confusion after the operation
This study looks at confusion or disorientation (delirium) that can happen after heart surgery. It aims to learn more about who might be affected and how to improve recovery.
Xi'an, ShaanxiAges 18 years+ - NCT06054360Recruiting
Predicting irregular heartbeat after heart bypass surgery
This study uses an ultrasound test of the heart's right atrium to see if it can predict who will develop an irregular heartbeat (atrial fibrillation) after planned coronary bypass surgery. If you are scheduled for this surgery and have no history of atrial fibrillation, you may be able to join.
AmiensAges 18 years+ - NCT05014802Recruiting
MRI scans before heart surgery to predict post-surgery atrial fibrillation
This study uses an MRI scan before heart surgery to look for heart scarring that may predict who will develop atrial fibrillation afterward. Knowing the risk ahead of time could help doctors monitor you more closely and plan prevention.
Covington, LouisianaAges 40–120 - NCT04299828Recruiting
Study of inflammation activity during complex heart surgery
This study measures how active white blood cells and inflammation are during complex heart surgery using a heart-lung machine. It may help doctors better understand what triggers inflammation during surgery and how to improve care.
Boston, MassachusettsAges Any age - NCT06958029Recruiting
Heart rhythm after heart surgery study
This study looks at how often a fast, irregular heartbeat (atrial fibrillation) happens after heart valve or bypass surgery. Knowing this could help doctors take better care of patients after these procedures.
Khon KaenAges 18 years+ - NCT06840327Recruiting
Oxygen levels during heart bypass surgery and recovery
This study looks at how different oxygen levels during heart bypass surgery might affect recovery. It aims to see if keeping oxygen at a certain level can improve outcomes for people having surgery where a vein from the leg is used to bypass a blocked heart artery.
ToulouseAges 18 years+ - NCT06487585RecruitingPhase 4
Angiotensin II as first pressor after heart surgery
This trial tests if starting Angiotensin II early, instead of other blood pressure medications, can help heart surgery patients maintain safe blood pressure. It may be an option if you have low blood pressure after surgery despite receiving fluids.
Towson, MarylandAges 18 years+ - NCT06425614Recruiting
Blood Cell Recycling During Heart Surgery Trial
This trial tests whether giving back a patient's own platelets and red blood cells during heart surgery can reduce bleeding and the need for donor blood transfusions. It is for people having certain types of high-risk heart surgery with a heart-lung machine.
Bordeaux, FranceAges 18 years+ - NCT07285187Recruiting
Vein congestion and confusion after heart surgery trial
This trial looks at how blood backing up in veins after heart surgery might relate to delirium (sudden confusion). It uses a special ultrasound to check vein blood flow and then watches for confusion afterward.
Yangzhou, JiangsuAges 18 years+ - NCT07052461Recruiting
Blood flow study in ICU patients after heart surgery
This study looks at blood flow patterns in patients after non-emergency heart surgery to see if they relate to recovery in the ICU. It uses a special ultrasound to check blood vessels in the belly and leg.
BaselAges 18 years+ - NCT06279000RecruitingPhase 3
Colchicine for heart risk during major non-heart surgery
This study tests whether a low-cost, anti-inflammatory drug called colchicine can reduce heart complications after major non-heart surgery. If you have heart or blood vessel risk factors and are scheduled for a major operation, this trial may help protect your heart.
Sankt Gallen, Canton of St. GallenAges 45 years+ - NCT07168421RecruitingPhase 4
Landiolol to prevent fast heart rate during major surgery
This trial tests a short-acting medicine called landiolol to see if it can prevent dangerously fast heart rates during and after major surgery. It is for people who have heart risks and are having a planned non-cardiac surgery.
BernAges 45 years+ - NCT07483151Recruiting
Heart Surgery and Thinking Changes Study
This study looks at how changes in blood flow (called venous congestion) after heart surgery might affect thinking and memory. It aims to find out if there is a link between how blood returns to the heart and brain function after surgery.
Yangzhou, JiangsuAges 18 years+ - NCT07683299Recruiting
New heart monitoring during bypass surgery
This study tests a new way to monitor your heart and blood flow during heart surgery that uses a heart-lung machine. The goal is to see if this integrated approach helps doctors make better decisions during the operation.
Medellín, AntioquiaAges 18 years+ - NCT06534372Recruiting
Factors affecting chronic pain after open-heart surgery
This study looks at factors that may lead to long-term pain after open-heart surgery. It follows patients who have coronary bypass or valve surgery to understand what might cause ongoing pain.
Ankara, AnkaraAges 18–80 - NCT07593794Recruiting
Quality of Recovery After Heart Surgery Study
This study measures how well patients recover after planned heart surgery by having them answer questions about their physical and emotional wellbeing. The goal is to understand what affects recovery so doctors can better support patients afterward.
KocaeliAges 18 years+ - NCT05353348Recruiting
Program to treat mild anemia around heart surgery
This trial tests a combined treatment plan to improve anemia (low blood count/iron levels) before and around the time of major elective heart surgery. It may help reduce the need for blood transfusions and support safer recovery.
Hangzhou, ZhejiangAges 18 years+ - NCT06775639Recruiting
Can we skip a heart artery test before surgery?
This study looks at whether people with adult congenital heart disease can skip a pre-surgery artery test (coronary angiography) if they already had a CT scan. If you qualify, you might help doctors find safer, simpler ways to prepare for heart surgery.
BolognaAges 18 years+ - NCT07070986Recruiting
Skin stimulation for anxiety before heart surgery
This trial tests whether a gentle skin stimulation device can lower anxiety and improve heart rate balance in people waiting for heart surgery.
BronAges 18 years+ - NCT06885268RecruitingPhase 3
Blood pressure management during non-cardiac surgery
This trial tests whether noradrenaline is better than standard care for preventing dangerously low blood pressure during surgery. If you are having non-cardiac surgery that lasts at least an hour and are expected to stay overnight, this study may be for you.
KatowiceAges 45 years+ - NCT06355063Recruiting
CellFX device for atrial fibrillation during open-heart surgery
This trial tests a new device called CellFX that uses nanosecond pulsed field ablation to treat atrial fibrillation during open-heart surgery. It may help you if you already need heart surgery and also have AFib.
ViennaAges 18–85 - NCT07205393Recruiting
Heart rehab after valve replacement surgery
This trial tests a phase one cardiac rehabilitation program for people who have had their mitral or aortic heart valve replaced. It aims to see if the rehab helps recovery. You might qualify if you had planned (not emergency) valve surgery and are stable enough for light exercise.
QinaAges 40–55 - NCT07022314Recruiting
Monitoring urine output in cardiac ICU patients
This trial tests a new device that tracks urine output after heart surgery to see how the body responds to fluids and diuretics. It may help doctors manage your recovery more closely.

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.
