Cycle and Stroke With Biofeedback for Power Symmetry
This trial studies the effect of biofeedback on power symmetry during cycling in stroke patients with lower extremity hemiparesis.
Salt Lake City, UtahAges 18–70 - NCT06672315Recruiting
Using a heart ultrasound for cardiac arrest outside the hospital
This study uses a special ultrasound probe placed in the esophagus to look at the heart during cardiac arrest happening outside the hospital. The goal is to see if this test can help doctors make better decisions for treatment.
New Taipei CityAges 18 years+ - NCT06685237Recruiting
Copenhagen heart failure with preserved pumping study
This study is for people in the Capital Region of Denmark who are at least 50 years old and have certain health conditions that put them at risk for a type of heart failure where the heart pumps normally but doesn't relax properly. The study aims to find and help people before heart failure develops.
HellerupAges 50–89 - NCT06859502Recruiting
National database for cerebrovascular disease research
This study creates a national database of people with cerebrovascular diseases (conditions affecting blood flow in the brain, like stroke or aneurysm). By joining, you help researchers better understand and improve care for these conditions.
Florence, FIAges Any age - NCT07341490Recruiting
Comparing CT scan vs angiogram to confirm brain death
This trial compares two imaging methods—CT angiography and traditional angiogram—to see if one is better at confirming complete loss of brain function (brain death) in people with severe brain injury. It may help doctors diagnose brain death more accurately and quickly.
StockholmAges 18 years+ - NCT07339813Recruiting
Understanding brain changes after stroke with advanced MRI
This study uses ultra-powerful MRI to see how the brain reorganizes after a stroke. It may help explain why some people recover arm movement and guide future therapies.
Gif-sur-Yvette, Île-de-France RegionAges 18–70 - NCT07336472RecruitingPhase 1/Phase 2
IBI3003 for relapsed or refractory multiple myeloma
This trial tests a new drug called IBI3003 for people with multiple myeloma that has come back or not responded to at least 3 prior treatments. The goal is to see if IBI3003 is safe and effective.
Scottsdale, ArizonaAges 18 years+ - NCT07342049Recruiting
Negative pressure therapy with silver for chronic leg wounds
