Recruiting studies
- NCT05732714Recruiting
Reduce heart event risk after major non-heart surgery
This study looks at ways to lower the chance of heart-related problems after major surgery that is not directly related to the heart. It focuses on people at higher heart risk who are expected to stay in the hospital for at least two days after surgery.
Toronto, OntarioAges 45–75 - NCT06471621Recruiting
Personalized care to prevent kidney injury after heart surgery
This trial tests whether personalized care can prevent acute kidney injury (sudden kidney damage) after heart or major blood vessel surgery. If you are having planned heart valve repair, bypass, or aortic surgery, you may be able to join.
BernAges 18 years+ - NCT05960604Recruiting
Monitoring blood pressure during surgery to predict low blood pressure
This study tests special ways of analyzing blood-pressure recordings during major surgery to better understand why some people develop low blood pressure (hypotension). If you have high blood pressure and need invasive blood-pressure monitoring, your surgery team will use readings to study patterns that may help predict or prevent low blood pressure.
AnkaraAges 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+ - NCT07745491Recruiting
AI tool to predict pneumonia after heart surgery
This study uses artificial intelligence to help predict if patients might develop pneumonia after heart or blood vessel surgery. It aims to find warning signs early so doctors can act sooner.
TomskAges 18 years+ - NCT07728539Recruiting
Comparing a faster ablation method for atrial fibrillation
This study compares a newer, faster type of ablation (high-power short-duration) with the standard approach for treating atrial fibrillation. The goal is to see which method is safer and more effective at restoring a normal heart rhythm.
MoscowAges 18–70 - NCT04669548Recruiting
Accuryn monitoring study for people having heart surgery
This registry collects information from patients who are monitored with the Accuryn system during heart surgery and their ICU stay. It helps researchers learn from the system’s signals to better understand patient care around cardiac procedures.
Los Angeles, CaliforniaAges 18 years+ - NCT04832568Recruiting
EEG monitoring to predict and prevent postoperative delirium
This study checks brain-wave signals during heart surgery (using EEG monitoring) to understand who is at risk for confusion after surgery. If you qualify, your team will track your thinking after the operation to help reduce or better manage postoperative delirium.
Wuhan, HubeiAges 18 years+ - NCT05806346Recruiting
TXA dosing for heart surgery patients on bypass
This trial studies whether giving tranexamic acid (TXA) based on patient needs during heart surgery works better than a one-size-fits-all approach. It may help reduce bleeding during surgery, while monitoring for clotting-related side effects.
SeoulAges 19 years+ - NCT06007755Recruiting
Finding blood markers for confusion after heart surgery
This study is looking for certain substances in the blood that may show up if a person becomes confused or delirious after heart surgery. The goal is to find early warning signs so doctors can help prevent or treat this confusion.
Wuhan, HubeiAges 18 years+ - NCT06253000Recruiting
Heat vs. Freezing for the Back of the Heart
This trial tests two ways to treat the back wall of the heart's left chamber in people with stubborn atrial fibrillation. It compares radiofrequency (heat) and cryoablation (freezing) to see which is safer and works better.
MoscowAges 18–80 - NCT06625996Recruiting
Carbs before surgery for faster recovery
This study looks at whether drinking carbohydrate-rich liquids before surgery helps you recover faster. It is for people with heart conditions, but not for those who need insulin for diabetes.
AsyutAges 18 years+ - NCT06706323Recruiting
Depression after heart surgery study
This study looks at depressive symptoms in people who have had heart bypass surgery. It aims to understand how patients feel emotionally after surgery and may help improve care.
ZurichAges 18–90 - NCT07388108Recruiting
Predicting heart rhythm problems after heart surgery
This trial studies whether measuring how the upper chambers of the heart work together can help predict dangerous heart rhythms after heart surgery. If you are in normal heart rhythm and not having mitral valve surgery, this study may help doctors better prevent complications.
Mendoza, MendozzAges 18–80 - NCT01932411Recruiting
Review of heart surgery outcomes at UC Davis
This study looks back at how people did after heart (cardiovascular) surgery at UC Davis Medical Center. It may help doctors understand what factors are linked to better or worse outcomes.
Sacramento, CaliforniaAges 18 years+ - NCT07063381Enrolling by invitation
Low-frequency stimulation for cognition in atrial fibrillation
This study tests whether low-frequency electrical stimulation can help improve thinking and memory in people with permanent atrial fibrillation and cognitive impairment. Participants will receive the stimulation and have their cognitive function checked over six months.
MoscowAges 60–90 - NCT06660602Recruiting
Brain function check before and after heart surgery
This study checks how well your brain works before and after heart surgery. It uses safe tests like a CT scan and an EEG to see if surgery affects brain function.
BeijingAges 18–80 - NCT07131605Recruiting
How weight-loss surgery affects heart health and inflammation
This study looks at how weight-loss surgery affects heart health by checking markers of inflammation in the blood and how blood vessels work. It may help understand why surgery lowers heart risk for people with obesity.
Cotignola, RavennaAges 18 years+ - NCT06115759Recruiting
Recovery and activity study after open-heart surgery
This study tests a new recovery plan called T-REX to see if it helps patients feel better and get back to moving sooner after open-heart surgery. It is for people having surgery at Thorax Centrum Twente.
Enschede, OverijsselAges 18 years+ - NCT05996120Recruiting
Finding the best temperature during heart-lung machine surgery
This study looks at the best body temperature to use during heart surgery when a heart-lung machine is needed. You may be able to join if you are having bypass surgery or valve repair, your risk score is moderate or higher, and your surgery is not an emergency.
Leicester, LeicestershireAges 18 years+ - NCT06873321RecruitingPhase 4
Blood thinners after leg artery surgery to prevent clots
This trial compares two blood-thinning strategies after leg artery surgery or angioplasty to prevent dangerous blood clots. Participants will receive either rivaroxaban plus aspirin or aspirin alone, and researchers will monitor for clots over 30 days.
Pernambuco, PernambucoAges Any age - NCT06724718Recruiting
Using a smartwatch to detect atrial fibrillation after chest surgery
This trial tests whether a smartwatch can detect atrial fibrillation in people who have had major chest surgery (like lung removal) within the last 48 hours. If successful, this could help catch heart rhythm problems early without extra hospital equipment.
AmiensAges 18 years+ - NCT05650307Recruiting
Heart and metabolic scan study of weight and rehabilitation
This study uses detailed heart scans and information about metabolism (how your body uses energy) to understand how metabolic treatments and heart rehabilitation may affect your health. You may qualify either as someone undergoing bariatric (weight-loss) care or as part of a heart rehabilitation group—or as a healthy comparison group.
Cleveland, OhioAges 18 years+ - NCT07634666Recruiting

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.
