Ultrasound test for kidney risk in ARDS patients
This study tests whether a special ultrasound of the veins (VExUS) can help predict kidney injury in people with severe breathing problems who are on a breathing machine and receiving medicine to support their blood pressure.

Spectral CT for diagnosing heart inflammation in chest pain
This study uses a special CT scan (called spectral CT) to look for inflammation of the heart muscle or other heart problems in people who come to the hospital with sudden chest pain. The goal is to see if this scan can help doctors diagnose the cause of your chest pain more accurately.
BolognaAges 18 years+ - NCT06107010Recruiting
Robotic exoskeleton for walking after stroke
This trial tests a robotic exoskeleton (Atalante) to help people who have had a stroke and have trouble walking. It looks at whether using the device early (1–4 months after stroke) can improve the ability to walk again.
CréteilAges 18 years+ - NCT06441630RecruitingPhase 3
Testing two new high blood pressure medicines together
This trial tests a combination of two new medications (AD-227A and AD-227B) to see if they work better together for people with essential (common) high blood pressure. It could be a new treatment option to help control your blood pressure.
SeoulAges 19 years+ - NCT06668792RecruitingPhase 2
Study of BCD-248 for returning multiple myeloma
This trial tests a new treatment called BCD-248 for people whose multiple myeloma has come back or stopped responding to at least two prior treatments. It aims to see if it is safe and effective.
KaliningradAges 18 years+ - NCT07438054Enrolling by invitation
Yearly heart-rhythm screening for adults 65 and older
This study tests whether monthly heart checks using a simple ECG (a quick test of your heart's electrical activity) can find a common heart-rhythm problem called atrial fibrillation earlier. You would visit your family health center once a month for 12 months to get the ECG done, no extra procedures or treatments are involved.
Ordu, OrduAges 65 years+ - NCT06806670Recruiting
Diet and exercise study for kidney transplant patients
This study tests whether a structured diet and exercise program can lower heart disease risk in kidney transplant recipients. If you've had a stable transplant for at least 6 months and up to 10 years, you may be able to join.
Bologna, BOAges 30–69 - NCT07439133RecruitingPhase 3
Comparing new heart scan with standard tests for coronary disease
This trial is testing a new imaging agent called XTR004 to see if it can accurately find blockages in the heart's arteries. If you have suspected or confirmed stable coronary heart disease, this study may offer a less invasive way to diagnose your condition.
BeijingAges 18–80 - NCT07443670Recruiting
Voice analysis for heart failure monitoring
This trial tests whether analyzing your voice recordings (taken daily) can detect changes in lung artery pressure. It could help monitor heart failure without extra clinic visits.
San Francisco, CaliforniaAges 18 years+ - NCT07444567RecruitingPhase 3
Continuing benralizumab treatment after a previous study
This trial lets people who completed an earlier benralizumab study and are benefiting from the medicine keep receiving it. The goal is to provide ongoing access while we continue to monitor safety and effectiveness.
Aurora, ColoradoAges 6 years+ - NCT07438327Recruiting
AI study to improve heart and aorta CT analysis
This trial uses artificial intelligence to better analyze CT scans of the aorta, the large artery that carries blood from your heart. If your CT scan shows the aorta is partly cut off or missing in the images, the AI will help measure the parts that are fully visible.
Chapel Hill, North CarolinaAges 22 years+ - NCT07436156RecruitingPhase 4
Stroke treatment study using a new clot removal system
This study looks at people who had an ischemic stroke and were treated with a special clot-removal device. It aims to learn how well this treatment works in real-world patients.
West Jordan, UtahAges 18 years+ - NCT07444320Recruiting
Testing new energy pulses for atrial fibrillation treatment
This trial tests a new way to deliver energy (FARAPULSE PFA system) to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to see if these new waveforms can safely and effectively stop AF symptoms and improve quality of life.
SplitAges 18 years+ - NCT07443696RecruitingPhase 2
Heart imaging test to see if bypass surgery could help
This study uses two imaging scans to see if parts of your heart muscle are still alive but not working well. This could help doctors decide if you might benefit from heart bypass surgery.
Beijing, Beijing MunicipalityAges 18–85 - NCT07444593Recruiting
Shin bone transport to heal diabetic foot ulcers
This trial tests whether a surgical technique called transverse tibial bone transport (TTT) can help heal chronic diabetic foot ulcers. TTT involves moving a small piece of the shinbone to encourage new blood vessels to grow to the wound, which may help it close.
Jacksonville, FloridaAges 22 years+ - NCT07442175Recruiting
Blood pressure monitor test for atrial fibrillation detection
This trial tests a blood pressure monitor that can also detect atrial fibrillation (an irregular heartbeat). You may join if you are 22 or older, have an average-sized arm, and either have been diagnosed with AF or have never had it — as long as you don't have a pacemaker or defibrillator.
Tianjin, Tianjin MunicipalityAges 22 years+ - NCT06753409Recruiting
Brain monitoring during anesthesia for major abdominal surgery
This study tests whether using a special brain wave monitor during anesthesia can improve recovery for people having major abdominal surgery lasting more than two hours.
AsyutAges 18–70 - NCT06175754Recruiting
Laser or injection for leg veins
This study compares two treatments for small leg veins (reticular veins): a laser treatment and a sclerotherapy injection. It aims to see which works better for women.
TambovAges 18–75 - NCT06806813Recruiting
Italian Fabry disease heart registry
This study is creating a registry of people with Fabry disease to better understand how it affects the heart. By joining, you help doctors learn more about the condition and improve care for future patients.
Chieti, Abruzzo/ChietiAges 2 years+ - NCT07439380Recruiting
Group care for high blood pressure and diabetes in Nepal
This trial tests whether group-based care can help people manage high blood pressure or diabetes better than standard care. If you live in one of the study areas in Nepal and have high blood pressure or diabetes, you may be able to join.
DhulikhelAges 18 years+ - NCT07438613Recruiting
Ultrasound of neck vein for fluid levels in dialysis
This trial uses ultrasound to check the fluid levels in people on long-term dialysis. It aims to see if this can help doctors better adjust their treatment.
BolognaAges 18 years+ - NCT07436962Recruiting
Loop recorder for mitral valve heart condition
This trial tests whether a small heart monitor (loop recorder) can help people with a specific mitral valve condition called mitral annular disjunction. It's for patients who have scar tissue in their heart muscle shown on an MRI.
BudapestAges 18–60 - NCT07436299Recruiting
New ultrasound method for heart pressure in atrial fibrillation
This study tests a new way to use ultrasound (echocardiogram) to measure heart pressure in people who have both heart failure and atrial fibrillation (irregular heartbeat). Participants will have an ultrasound and a heart catheterization to see if the new ultrasound method can accurately detect elevated pressures.
Cleveland, OhioAges 18 years+ - NCT07439991Recruiting
Study of blood clot risks after lung cancer surgery
This study looks at why some people develop blood clots after lung cancer surgery. By tracking your recovery for 30 days, researchers hope to find better ways to predict and prevent clots in the future.
