Recruiting studies
- NCT06692309Recruiting
Can brain wave patterns predict thinking problems after heart surgery?
This study uses a brain wave recording device (EEG) during heart surgery to see if it can predict short-term confusion or memory problems after the operation. It may help doctors find and treat thinking issues earlier.
Beijing, Beijing MunicipalityAges 60 years+ - NCT07699016Recruiting

Blood recovery during heart surgery study
This trial tests if a machine that collects and reuses blood during heart surgery can help patients avoid needing donor blood transfusions. It is for people having a first-time coronary bypass or heart valve surgery.
Recife, PernambucoAges 18 years+ - NCT06420479Recruiting
How weight-loss surgery affects heart disease risk
This study looks at how weight-loss surgery (bariatric surgery) affects the chances of developing heart disease or dying early. It may help you if you have obesity but have never had heart problems or cancer before.
StockholmAges 18 years+ - NCT07094087RecruitingPhase 3
Blood clotting medicine for heart surgery bleeding

Los Angeles, CaliforniaAges 18 years+ - NCT05531474Recruiting
Bariatric surgery to lower future heart and stroke events
This trial looks at whether weight-loss surgery can reduce the chances of heart attack, stroke, or other serious heart problems in people at higher heart risk. You might be offered surgery and followed over time to see if cardiovascular events are reduced.
Hamilton, OntarioAges 18 years+ - NCT07622823Recruiting
Nerve Blocks to Reduce Pain After Heart Surgery
This study tests whether special numbing injections around nerves (called fascial plane blocks) can help reduce pain and improve recovery after planned heart surgery. The goal is to see if this technique helps patients manage pain better and recover faster.
AntalyaAges 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+ - NCT04444349Recruiting
CoQ10 to reduce inflammation after heart surgery
This study tests whether CoQ10 (a natural nutrient) can lessen harmful inflammation and help protect organs after cardiovascular surgery. If you qualify, you may receive CoQ10 during the surgical period and be followed for how your body responds.
Beijing, Beijing MunicipalityAges 18–90 - 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 - NCT04444362Enrolling by invitation
Probacine to protect organs after cardiovascular surgery
This study tests whether a medicine called Probacine can help protect your gut and organs after cardiovascular surgery. If you qualify, you may be asked to take part and follow the study plan to see if complications are reduced.
Beijing, Beijing MunicipalityAges 18–90 - 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 - NCT06551714Recruiting
Movement techniques after first open heart surgery
This study tests special movement and breathing techniques to help people recover faster after their first open heart surgery. It focuses on improving health in the early days after surgery.
AnkaraAges 18–75 - NCT07483502Recruiting
Pre-surgery gut health supplement study for heart patients
This trial tests whether taking a gut health supplement (WellBiome) for six weeks before heart surgery can improve recovery and save the NHS money. It compares the supplement to a placebo (a pill with no active medicine).
Hull, East Riding Of YorkshireAges 50–80 - NCT05000996Recruiting
Gut microbiome study for people having metabolic surgery
This study looks at your gut bacteria (your “microbiome”) around the time of metabolic surgery. It may help researchers understand how surgery affects gut health and related conditions like diabetes, blood pressure, and cholesterol.
Nashville, TennesseeAges 21–65 - NCT06702553RecruitingPhase 3
Nitric oxide to reduce support after heart surgery
This trial tests whether giving nitric oxide gas during heart surgery can help patients recover faster and need less breathing and circulation support afterward. It is for people having planned heart or aortic surgery with a heart-lung machine for the first time.
Boston, MassachusettsAges 18 years+ - NCT07539532Recruiting
AI model to predict heart problems after stomach surgery
This study compares a new artificial intelligence tool with traditional methods to predict which patients might have heart-related complications after gastrointestinal surgery. The goal is to find better ways to identify high-risk patients and potentially improve their care.
Hà NộiAges 16 years+ - NCT07557108Recruiting
Nerve Blocks to Improve Recovery After Heart Surgery
This study tests whether special numbing injections around nerves in the chest wall (fascial plane blocks) help patients recover better and have less pain after open-heart surgery. The goal is to see if this technique improves how you feel and function in the days after your operation.
Ordu, AltinorduAges 18–70 - 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+ - NCT06961175Recruiting
Platelet function study in heart surgery
This study looks at how well platelets work during heart surgery using a special test called thromboelastography. It may help doctors understand and manage bleeding risks in people having planned heart surgery with a heart-lung machine.
SalamancaAges 18 years+ - NCT07048002Recruiting
Silent brain infarct and cognitive decline after heart surgery
This trial tests a bundle of interventions to prevent silent brain infarctions (small 'silent' strokes) and thinking problems after heart or blood vessel surgery with a heart-lung machine. If you are 60 or older and having such surgery, this study may help protect your brain health.
Beijing, Beijing MunicipalityAges 60 years+ - NCT06739005Recruiting
AI model to assess heart surgeon technique in bypass surgery
This study tests whether an artificial intelligence (AI) model can accurately evaluate the surgical technique of heart surgeons performing a common bypass procedure. If you are a first-time bypass patient and do not have certain heart or organ conditions, you may be able to participate and help improve surgical training tools.

Common questions
- Are there clinical trials for cardiovascular surgery?
- Yes. Clin2 currently lists 57 recruiting cardiovascular 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 cardiovascular 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 cardiovascular 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.
