Frailty Score and Blood Pressure Changes During Surgery
This study looks at a simple scoring system (EASIX) that predicts whether older or frail patients will experience dangerous blood pressure drops when anesthesia is given before surgery. Understanding this risk might help doctors better protect vulnerable patients during their operations.
KonyaAges 18 years+ - NCT05604131RecruitingPhase 2
Cardiac MRI-guided iron-chelator treatment after a heart attack
This Phase 2 trial tests whether giving deferiprone (an “iron-chelator,” meaning it helps remove excess iron) guided by cardiac MRI can improve outcomes after an acute anterior heart attack. It aims to study safety and benefit for people who can undergo MRI with contrast and meet specific heart, kidney, liver, and blood criteria.
Indianapolis, IndianaAges 18–79 - NCT07400406Recruiting
A new MRI test to see calcified heart arteries
This trial tests a special MRI using a contrast agent called ferumoxytol to better see calcium buildup in heart arteries. It may help people who need a coronary angiogram and have some calcium visible on a prior CT scan.
Nanjing, JiangsuAges 18–75 - NCT06324461RecruitingPhase 4
GLP-1 drug to protect heart after non-emergency surgery
This study tests whether a GLP-1 receptor agonist (a medication used for diabetes and weight loss) can reduce heart damage during or after planned non-cardiac surgery. It may help patients with heart risk undergoing intermediate to high-risk procedures.
Hong Kong, Hong Kong SARAges 18 years+ - NCT07270536Recruiting
Pacing and heart pressure in HFpEF exercise
This study tests whether a special pacing setting during exercise can help improve heart filling pressures in people with heart failure with preserved ejection fraction (HFpEF) who already have a DDD pacemaker. If you have HFpEF and a pacemaker, you may help researchers find better ways to manage your condition during activity.
HasseltAges 18 years+ - NCT07611045Recruiting
Understanding recovery and care after heart surgery
This study asks patients and their families about their experience after heart surgery (like bypass or valve repair) to help doctors improve follow-up care. You'll share your story through an interview, and your feedback could help future patients.
Bristol, BristolAges 18 years+ - NCT07503236Recruiting
Study of a new device for leaking heart valves
This trial tests a new device designed to fix a leaky mitral valve in people with heart failure. It may help you breathe easier and feel less tired if your valve leak is severe and medicines have not been enough.
Sacramento, CaliforniaAges 21 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+ - NCT07226479Recruiting
Non-invasive vein pressure test for heart patients
This study tests if a non-invasive method can estimate central venous pressure, reducing the need for invasive catheters in heart patients.
New Haven, ConnecticutAges 18 years+ - NCT07081009Recruiting
Heart injury after planned back surgery study
This study is looking at whether patients having planned lower back surgery experience any heart stress afterward. It aims to understand how common this is and what might help protect the heart.
AnkaraAges 18 years+ - NCT07603648Recruiting
How different pacemaker lead positions affect heart rhythm signals
This study looks at how placing a pacemaker lead (a thin wire) in different spots in the upper heart chamber affects electrical signals. It may help doctors choose the best position for future pacemakers.
Zunyi, GuizhouAges 18 years+ - NCT06226987Recruiting
Heart imaging study for Fabry disease
This study uses special MRI scans to look at how Fabry disease affects the heart. It may help researchers understand the disease better.
Cambridge, CambridgeshireAges 18 years+ - NCT05089149Recruiting
Check how lung ultrasound helps manage heart failure congestion
This study looks at people with long-term worsening heart failure who are coming to the hospital for a planned visit, to see how checking “congestion” (fluid buildup) may guide care. It may help the team understand whether lung ultrasound can better assess who needs treatment changes.
Vandœuvre-lès-NancyAges 18 years+ - NCT05097898Recruiting
Check fluid buildup in heart failure with normal pumping
This study evaluates how well doctors can assess “fluid congestion” in people with chronic heart failure where the heart’s squeezing is still preserved. It may help improve how patients are monitored during hospital visits.
Vandœuvre-lès-NancyAges 18 years+ - NCT06230198Recruiting
Effect of a blood-saving technique on transfusions after heart surgery
This trial tests whether a technique called retrograde autologous priming (using the patient's own blood to prepare the heart-lung machine) can reduce the need for blood transfusions during heart surgery. It is looking at hospitals and surgical teams, not individual patients, so it's not a typical trial you can join directly.
Winnipeg, ManitobaAges 10–110 - NCT07061548Recruiting
Predicting heart output changes during surgery using capnography
This trial uses a computer algorithm to predict changes in how well your heart pumps blood during surgery. It looks at carbon dioxide levels in your breath to make these predictions. This could help doctors adjust care in real time.
SeoulAges 19–75 - NCT06513416Recruiting
Gut bacteria and lung problems after surgery in older adults
This study tests whether the bacteria in your gut are linked to lung complications after a long abdominal surgery. If you are 65 or older and having a scheduled upper abdominal surgery, researchers want to understand how your microbiome affects your recovery.
Beijing, Beijing MunicipalityAges 65 years+ - NCT07172620Recruiting
Heart bypass surgery without clamping the aorta
This study tests a special technique for heart bypass surgery that avoids clamping the aorta. It may help people with hardened arteries in the aorta who need bypass surgery but are not good candidates for standard clamping.
Beijing, Beijing MunicipalityAges Any age - NCT07044128Recruiting
Testing a new electronic stethoscope for heart murmur checks
This study is testing a new electronic stethoscope (called Keikku) to see if it works well and is safe for checking heart murmurs in children and adults who are not in an emergency situation. If it works, it could give doctors a better tool for evaluating heart sounds.

Study registry of heart imaging for suspected blocked heart flow
This study collects results from two types of heart imaging—cardiac PET and CardioFlux magnetocardiography—in people with suspected reduced blood flow to the heart. It may help researchers better understand which imaging findings match coronary ischemia and how the tests compare.
Cleveland, OhioAges 40 years+ - 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+ - NCT05775484Recruiting
Exercise program to slow heart and blood vessel aging
This trial tests whether a structured exercise program can slow how quickly your cardiovascular system (heart and blood vessels) “ages” over time. If you’re able to move around outdoors safely, exercise may be a key part of the study.
Singapore, SingaporeAges 21–100 - NCT07128849Recruiting
Upper arm exercise after heart bypass surgery
This study tests whether adding arm cycling exercises to standard recovery helps people recover better after a coronary artery bypass graft (CABG, also known as heart bypass surgery). It is for patients who are stable enough to start moving soon after surgery.
Lahore, Punjab ProvinceAges 40–65 - 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.
