This study tests whether hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can help recovery after emergency clot-removal surgery for large blood vessel strokes. The goal is to see if extra oxygen can reduce brain damage and improve outcomes.
Beijing, Beijing MunicipalityAges 18–80 - NCT07626710Recruiting
How Heart Valve Replacement Affects Kidney Function
This study looks at whether a minimally invasive heart valve procedure (TAVI) affects how well your kidneys work. Researchers will track your kidney function before and after the procedure using blood tests to understand any changes.
Roma, RMAges 18 years+ - NCT07626879Recruiting
Ring Blood Pressure Device Compared to Standard 24-Hour Monitoring
This study tests whether a new ring-shaped blood pressure device works as well as the standard 24-hour ambulatory blood pressure monitor in people with heart failure. If the ring device is accurate, it could offer a simpler, more convenient way to track blood pressure at home.
DaeguAges 19 years+ - NCT07627399Recruiting
Best Care Practices for Stroke in Regular Hospital Units
This study tests whether following best-practice guidelines for stroke care in regular hospital units (rather than specialized stroke centers) helps patients recover better. Researchers will track how well patients do when they receive standardized stroke care protocols.
Antequera, MálagaAges 18 years+ - NCT07627516Recruiting
Spinal cord stimulation for arm and leg weakness after stroke
This trial tests whether a spinal cord stimulation device—a small implant that sends gentle electrical signals to your spinal cord—can help improve arm and leg strength and movement in people who had a stroke at least 6 months ago and haven't fully recovered with regular therapy. The goal is to see if this treatment is safe and effective.
Hangzhou, ZhejiangAges 20–80 - NCT07628374Recruiting
Balance training after stroke: sensorimotor vs dual-task
This study tests two different ways to help people recover balance and walking ability after stroke. You'll do either sensorimotor training (exercises focused on body awareness and coordination) or dual-task training (exercises that combine physical movements with mental tasks), and researchers will measure which approach works better.
Rajanpur, Punjab ProvinceAges 40–60 - NCT07629011Recruiting
Mental imagery and robotic hand training after stroke
This trial tests whether combining mental imagery practice with a robotic hand device can help improve hand function in people who had a stroke at least 6 months ago. The robotic hand reads signals from your arm muscles to help you practice controlled movements.
Rawalpindi, Punjab ProvinceAges 18–70 - NCT07630857Recruiting
Heart Mapping to Personalize Atrial Fibrillation Treatment
This trial tests a new way to map the heart's electrical signals to help doctors better target and treat atrial fibrillation (an irregular heartbeat). If you're having a procedure to treat AF, this study may help improve the success of your treatment.
Beijing, Beijing MunicipalityAges 18–80 - NCT07631078Recruiting
Brain Stimulation to Improve Arm Movement After Stroke
This pilot study tests whether a combination of brain stimulation (TMS) and physical therapy can help improve arm and hand function in people who had a stroke at least one year ago. The goal is to see if this approach helps patients regain better control and strength in their affected arm.
Berkeley, CaliforniaAges 18–80 - NCT07632586Recruiting
First-in-Human Heart Pump Implant Study
This trial tests a new tiny heart pump called the Icoms Flowmaker for patients with severe heart failure who cannot have a standard heart pump. The device may help your heart pump blood better and improve your ability to do daily activities.
PragueAges 18–80 - NCT07633587Recruiting
Cancer Survival Study After Heart Inflammation from Immunotherapy
This research tracks outcomes for cancer patients who developed heart inflammation (myocarditis) while receiving immune checkpoint inhibitor therapy. By studying survival patterns, researchers hope to better understand how to manage this serious side effect and improve care for future patients.
ParisAges Any age - NCT07634991RecruitingPhase 4
N-acetyl Cysteine for Diabetic Eye Disease
This study tests whether a supplement called N-acetyl cysteine can help slow or improve mild to moderate diabetic eye disease (diabetic retinopathy). The goal is to see if it's safe and effective for people with type 2 diabetes.
CairoAges 18–70 - NCT07635498Recruiting
Virtual versus in-person care after stroke
This study compares two ways of caring for stroke patients who aren't candidates for emergency clot-removal surgery. Half will receive care through a virtual stroke unit (telemedicine), and half will receive traditional in-person care at the hospital. The goal is to see if both approaches work equally well for recovery and safety.
SevilleAges 18 years+ - NCT07635758RecruitingPhase 1/Phase 2
Stem Cell Treatment for Recent Stroke Recovery
This trial tests whether special cells from human placenta can help your brain recover after a recent stroke. The treatment is given as an injection and aims to reduce long-term disability.
BeijingAges 18–80 - NCT07635784Recruiting
Hemorrhoid Treatment Registry: Tracking Embolization Safety
This registry collects information about a minimally invasive procedure called hemorrhoidal artery embolization (HAE), which blocks blood vessels feeding internal hemorrhoids. It's for adults with persistent bleeding hemorrhoids that haven't improved with standard treatments like creams or medications.
Libertyville, IllinoisAges 18 years+ - NCT07636759Recruiting
AI Heart Rhythm Test for Heart Pump Weakness
This study tests whether an artificial intelligence system can detect a weakened heart pump using an ECG (heart rhythm test). If successful, it could help doctors diagnose heart problems faster and more easily.
Suwon, Gyeonggi-doAges 19 years+ - NCT07637084Recruiting
Light therapy for chronic pain and fatigue in Ehlers-Danlos Syndrome
This trial tests whether a non-invasive light therapy called photobiomodulation can reduce chronic pain and fatigue in people with hypermobile Ehlers-Danlos Syndrome (hEDS), a genetic condition affecting connective tissue. The light is applied to the skin and may help cells produce energy and reduce inflammation.
