Recruiting studies
- NCT04915261RecruitingPhase 4

Predicting memory changes after heart surgery in older adults
This study looks at older adults having heart surgery to find out who might have trouble thinking or remembering afterward. Researchers hope to build a tool to predict this risk so doctors can help sooner.
ShanghaiAges 65 years+ - NCT06179329Recruiting
Comparing two types of heart bypass grafts in women
This trial compares two types of grafts (the radial artery from the arm and a vein from the leg) used in women having heart bypass surgery for the first time. It aims to see which graft works better and stays open longer.

Comparing Blood Flow Methods During Aortic Arch Surgery
This study compares two methods of supplying blood to the brain during surgery on the main artery from the heart (aorta) and the aortic arch. It may help determine the safest way to protect the brain during cooling and surgery.
Durham, North CarolinaAges 18 years+ - NCT06196307Recruiting
Early warning system for sudden chest pain
This trial is for people who come to the emergency room with new or worsening chest pain not caused by an injury. It aims to build an early warning system to better classify and treat chest pain.
Beijing, ChaoyangAges 18 years+ - NCT05934409Recruiting
Measuring body-fat storage after bariatric surgery
This study looks at how body fat is stored and how that may relate to early improvements in diabetes and heart/liver health after bariatric surgery. It may help researchers understand why some people recover faster and which body changes matter.
Sherbrooke, QuebecAges 18–65 - 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 - NCT06465277Recruiting
Heart MRI and stress test after lung or esophagus surgery
This study uses a heart MRI with a stress medication to see how well the right side of the heart pumps after lung or upper digestive surgery. It may help doctors understand heart recovery after these operations.
Belfast, Northern IrelandAges 18 years+ - NCT06519747Recruiting
Detecting irregular heartbeat after non-heart surgery
This trial uses a monitoring device to check for a common but often overlooked irregular heartbeat (atrial fibrillation) after non-cardiac surgery. The goal is to detect and treat it early to prevent complications like stroke.
Hamilton, OntarioAges 18–120 - NCT06336213Recruiting
Using a blood test to guide antibiotics in aorta surgery
This trial checks if a blood test called presepsin can help doctors decide when to use antibiotics in patients having surgery on the chest's main artery (the thoracic aorta). It is for people with an aneurysm or tear in that artery.
Moscow, MoscowAges 18–75 - NCT07603336Recruiting
Heart Monitoring Methods During Pancreas Surgery
This study compares two ways of monitoring your heart function during Whipple surgery (pancreas removal). Doctors will use different monitoring approaches to guide fluid and medication during your operation to help you recover better.
Çankaya, AnkaraAges 18–80 - NCT07609680Recruiting
Blood Pressure vs. Heart Output Monitoring During Colon Surgery
This trial compares two ways doctors monitor your body's circulation during colorectal surgery. One method tracks blood pressure; the other tracks how much blood your heart pumps. Researchers want to see which approach leads to better outcomes and fewer complications.
Ankara, Yenimahalle\AnkaraAges 18–80 - 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.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05094843Recruiting
Mini-invasive surgery for lung cancer and heart rhythm changes
This study looks at how lung cancer surgery affects the heart’s electrical signals and stress response, using heart tracing tests (ECG) around the time of surgery. It may help doctors better understand and monitor heart risks in people having curative, minimally invasive lung cancer surgery.
Tampere, PirkanmaaAges 18 years+ - NCT06336746Recruiting
Heart function during steep head-down position in robotic surgery
This study looks at how your heart performs during robotic surgery when you are placed in a steep head-down position. It may help doctors better understand how to keep you safe during the procedure.
Karlstad, Värmland CountyAges 18 years+ - NCT07303855Recruiting
Better fluid management after major abdominal surgery
This study compares two ways of giving fluids to people after major abdominal surgery in the ICU. It will see if using a measure of how much blood the heart pumps (cardiac index) is better than the usual method based on vein pressure.
Jakarta Pusat, DKI JakartaAges 18–65 - NCT06101108Recruiting
Early heart screening in back surgery patients
This trial checks people having back surgery for spinal stenosis to see if they have an early sign of heart amyloidosis (a protein buildup in the heart). The goal is to find this condition early so it can be treated before it causes problems.
BrugesAges 60 years+ - 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 - NCT07729891Recruiting
Vital sign monitoring after urological surgery
This study tests a system that constantly watches your vital signs (like heart rate and blood pressure) after urological surgery, to catch problems early. It's for people who are not expected to need the Intensive Care Unit after their operation.
Parma, ParmaAges 18 years+ - NCT06089902Recruiting
European registry for anomalous aortic origin of coronary arteries
This is a European registry for people with an anomalous origin of a coronary artery from the aorta (AAOCA). It will track how the condition is treated—whether with surgery or monitoring—to learn what works best.
Padova, PDAges Any age - NCT04114799Recruiting
Tests brain-surgery monitoring to optimize circulation
This study checks a monitoring approach during brain tumor surgery to help control blood flow and heart-related measurements. It may benefit you by making surgery safer and helping the team respond faster during the operation.
Hradec KrálovéAges 18 years+ - NCT06857838Recruiting
Bypass surgery for symptomatic myocardial bridge
This trial tests whether bypass surgery is effective for people with a myocardial bridge (a heart muscle that arches over an artery) that still causes symptoms despite medication. It aims to see if surgery can improve symptoms and outcomes.

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.
