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+ - NCT05373498Recruiting
Registry for children’s heart emergencies after resuscitation
This trial is a registry that collects information about children (under 18) who have congenital heart problems and need resuscitation with chest compressions. It helps doctors understand these emergencies and may improve future care for similar patients.
Leipzig, SaxonyAges Up to 18 years - NCT07472959RecruitingPhase 4
Morphine for pain after heart bypass surgery
This study tests whether giving morphine during coronary artery bypass surgery can help control pain after the operation. It is for people having planned heart bypass surgery who are moderately sick and not already on strong pain medicines.
Istanbul, Outside of the USAges 18–80 - NCT05738408Recruiting
Remote smoking help for hospitalized heart patients
This trial tests a phone-based (remote) smoking quit program for people hospitalized for a recent heart-related event. It may help you quit smoking by offering support when you’re in the hospital and afterward.
Burlington, VermontAges 18 years+ - NCT06784440Recruiting
Finding noninvasive markers of graft injury after heart transplant
This study looks for noninvasive markers (like blood or urine tests) that can show if a heart transplant is being injured. It aims to make monitoring safer and easier for children and adults with congenital heart disease who have had a transplant.
BolognaAges Up to 44 years - NCT06735378Recruiting
Exercise before dialysis to protect the heart
This study tests if doing gentle exercise just before dialysis can help prevent heart damage that sometimes happens during treatment. You may be able to join if you are on long-term dialysis and have not been exercising vigorously.
London, OntarioAges 18–79 - NCT07469943Recruiting
Diabetes drug after heart attack
This study tests whether a diabetes medication can improve artery health and heart function after a heart attack. It is for people who have had a STEMI and also have diabetes or a weakened heart pump.
Athens, Rimini1/HaidariAges 18–80 - NCT07468383Recruiting
Catheter ablation for slow heart rate study
This study tests a catheter procedure to treat a slow heart rate (bradycardia) that causes symptoms like dizziness or fainting. It may be an option for people who haven't had a pacemaker and whose heart can still speed up with medication.
Beijing, ChinaAges 18–65 - NCT06790277Recruiting
Foam cushion study for heart surgery patients
This trial tests a special foam cushion for heart surgery patients, to see if it helps prevent pressure sores. You may be able to join if you are at risk for pressure sores but do not have any yet.
Mecca, Western ReaganAges 18 years+ - NCT04576130Recruiting
ICD study after cardiac arrest from an abnormal heart rhythm
This study looks at an implantable defibrillator (ICD) strategy in people who survived a cardiac arrest caused by an abnormal rhythm (ventricular fibrillation or ventricular tachycardia). It aims to reduce the risk of another dangerous rhythm after the blocked heart arteries are fully treated.
CopenhagenAges 18 years+ - NCT06493227Recruiting
Extended use of bleeding control drugs after heart surgery
This trial is for hospitals, not patients. Hospitals that do many open heart surgeries and whose doctors agree to use certain bleeding control drugs (fibrinolysis inhibitors) as per the study protocol can participate.
Saint PetersburgAges 18 years+ - NCT04262830Recruiting
Heart scans to predict future heart failure after chemotherapy
This trial uses detailed heart imaging (a special MRI scan) to see how chemotherapy may have affected your heart and to predict who could develop heart failure later. If you qualify, it may help your care team better monitor your heart health over time.
San Diego, CaliforniaAges 13–39 - NCT07454564Recruiting
Heart function and surgery risk in older adults
This study looks at how well the heart pumps blood to predict recovery after abdominal surgery in people 65 and older. It uses an ultrasound of the heart (echocardiogram) to measure heart power and a standard score to estimate surgical risk.
KonyaAges 65 years+ - NCT07455292Recruiting
Heart valve study using advanced MRI
This study uses a special type of MRI, called 4D flow MRI, to better understand how severe aortic stenosis (a narrowed heart valve) affects heart function. It may help doctors learn more about different types of this condition and improve future treatment.

Imaging heart uptake of bone tracer in ATTR amyloidosis
This study uses special imaging tracers to see how much they build up in the heart in people with cardiac transthyretin (ATTR) amyloidosis. It may help researchers better measure disease activity and understand who benefits from treatments like tafamidis.
