Los Angeles, CaliforniaAges 18–99 - NCT06937658Recruiting
Better remote care for heart device patients
This study tests a new alert system for people with pacemakers or defibrillators that can send information directly to your care team. The goal is to improve how quickly problems are found and treated.
Boston, MassachusettsAges 18 years+ - NCT04114435Recruiting
Heart and lung testing in extremely premature babies
This study looks at how the hearts and lungs work in babies born very early (before 29 weeks). It may help researchers understand why some babies develop breathing and heart circulation problems and how to measure their recovery.
Montreal, QuebecAges 1 week–5 years - NCT04644094Recruiting
Dexamethasone for heart function after very early birth
This study looks at how giving a steroid medicine (dexamethasone) after very early birth affects the baby’s heart function. It may help doctors better understand risks and benefits for babies who need treatment for serious lung problems.
Montreal, QuebecAges 1 minute+ - NCT06923267Recruiting
Ultrasound to check heart function during breathing trials
This trial tests if using ultrasound to monitor your heart during a breathing test can help predict if you will need the breathing tube again. It is for people on a ventilator for at least 24 hours who are at higher risk of needing the tube reinserted.
OrléansAges 18 years+ - NCT06324149Recruiting
Frailty and aging conditions in chronic diseases
This study looks at how frailty affects the course of chronic diseases and how chronic diseases affect frailty. It may help understand aging-related conditions better.
MilanAges 18–100 - NCT06907849Enrolling by invitationPhase 2
Imaging amyloid in spinal stenosis and carpal tunnel
This trial tests a special scan that uses a radioactive tracer to look for amyloid protein deposits in people who have had surgery for lumbar spinal stenosis (narrowing of the spine in the lower back) or carpal tunnel syndrome. The goal is to see if the scan can detect these deposits, which may be linked to ongoing orthopedic issues.
Knoxville, TennesseeAges 60 years+ - NCT06908590Recruiting
Community health worker help for heart rehab after a heart event
This trial tests whether a community health worker (a trained person from your community) can help people with low income join and stick with a heart rehab program after a heart event. The goal is to make heart recovery easier and more accessible.
Baltimore, MarylandAges 21 years+ - NCT06900257Enrolling by invitation
Fetal heart function in fasting pregnant women
This study looks at how babies' hearts work when mothers have been fasting for at least 10 days. It may help understand if fasting affects the baby's heart health.
SanliurfaAges 18–50 - NCT06895603Recruiting
New cuff to measure blood flow during heart procedures
This trial tests a new upper-arm cuff that may measure your heart's blood flow without needing an extra tube in your heart. If you already need a special heart catheter and a wrist arterial line, this study will see if the cuff works just as well.
Charlottesville, VirginiaAges 18 years+ - NCT06895590Recruiting
Testing a new water-based blood pressure cuff
This trial tests a new, very accurate blood pressure cuff that uses water to get a better reading. It is for adults who already need a standard blood pressure cuff and an arterial line as part of their hospital care.
Boston, MassachusettsAges 18 years+ - NCT06885164Recruiting
Remote heart monitoring for heart failure patients
This trial tests whether remote monitoring of heart function can help manage heart failure. It may be an option if you have symptoms like shortness of breath or fatigue (NYHA class II or higher) and are between 18 and 90 years old.
Aalborg, DenmarkAges 18–90 - NCT06887283Recruiting
Essen Amyloidosis Registry Study
This study collects information from people with suspected or confirmed amyloidosis. The goal is to learn more about the condition and improve patient care.
Essen, North Rhine-WestphaliaAges 18 years+ - NCT06868797Recruiting
Dapagliflozin for advanced heart failure patients waiting for transplant
This study tests whether dapagliflozin (a medicine already approved for other heart conditions) can help protect kidney and heart function in people with very advanced heart failure who are waiting for a heart transplant. If you qualify, you'll help researchers learn if this drug offers extra benefits beyond standard care.
BronAges 18 years+ - NCT06875583Recruiting
Reducing radiation during heart catheter procedures
This trial tests a new way to reduce the amount of radiation you receive during a heart procedure (like angioplasty or stenting) done through the wrist. It aims to make the procedure safer for patients and staff.
LiverpoolAges 18 years+ - NCT06870175Recruiting
Smart shirt heart monitoring trial
This trial tests a smart textile ECG monitor worn as a shirt to track your heart rhythm for up to 14 days. It may replace the usual sticky electrodes and wires, making monitoring more comfortable.
Newmarket, OntarioAges 18 years+ - NCT05574296RecruitingPhase 1
Test hydrogen gas for children needing emergency heart resuscitation
This early safety study tests whether “hydrogen” can be given to children during emergency heart resuscitation that isn’t improving with standard efforts. It’s meant to see if the treatment is safe and feasible for a very specific, life-threatening situation.
Washington D.C., District of ColumbiaAges Any age - NCT06715371Recruiting
Heart chamber measurements during heart surgery
This study compares two types of ultrasound of the heart—one done on the chest and one done through the throat—to see if they give similar measurements. It may help people having planned heart surgery who have normal heart function.
Toronto, OntarioAges 18 years+ - NCT06771700Recruiting
S-ICD implantation study for heart patients
This study looks at implanting a type of ICD (implantable cardioverter-defibrillator) called a subcutaneous ICD, or S-ICD, which goes under the skin instead of in the heart. It is designed to help see how well this works in standard care.
Cologne, North Rhine-WestphaliaAges Any age - NCT06831409Recruiting
