Wuhan, HubeiAges 18 years+ - NCT07705906Recruiting
Robot-assisted leg training for mobility recovery
This trial tests a robot device to help people with leg weakness from stroke, spinal cord injury, or joint surgery improve their walking. It may be a good option if you are medically stable and can work with the robot safely.
Dhaka, Dhaka DivisionAges 18–70 - NCT07702968Recruiting
Low-field MRI for stroke patients in the ER
This trial uses a low-field MRI machine to scan the brains of people with suspected stroke who come to the emergency room. It aims to see if this type of MRI can help doctors make faster and better decisions about treatment.
Leiden, South HollandAges 18 years+ - NCT07704164RecruitingPhase 2
Colchicine to lower heart artery swelling in HIV
This trial tests if colchicine, a medicine for inflammation, can reduce swelling in the heart arteries of people with HIV. It may help lower the risk of heart problems in those already on a statin or similar medication.
BarcelonaAges 50 years+ - NCT07698405Recruiting
Advanced rehab technology for arm recovery after stroke
This study tests whether advanced technology-based rehabilitation can help people who have had a stroke regain movement and use of their affected arm. It may be a good option if you have had a single stroke and still have some arm weakness but no severe muscle tightness or memory problems.
Fiorenzuola d'Arda, PiacenzaAges 18 years+ - NCT07705256Recruiting
Virtual-reality training using muscle signals for arm recovery after stroke
This trial tests a virtual-reality training system that uses muscle signals to help people regain arm movement after a recent stroke. It may be an option if you had a stroke within the last 2 weeks and have arm weakness.
LondonAges 18 years+ - NCT07699016Recruiting
Hemostatic agent use in heart and blood vessel surgery
This trial surveys surgeons about how they use hemostatic agents (medications that stop bleeding during surgery). It aims to understand current practices and improve patient safety.
Milan, MIAges 18 years+ - NCT07701876Recruiting
Heart failure recovery markers study
This study looks for markers in the blood that can predict whether the heart's pumping function improves in people with chronic heart failure. It may help doctors understand which treatments work best for each person.
Shanghai, Shanghai MunicipalityAges 18–90 - NCT07702643Recruiting
Walking practice at home after stroke
This study tests a home-based walking program for people who have recently had a stroke. It combines behavioral coaching with guided stepping exercises to help improve mobility and confidence when walking after returning home from the hospital.
Calgary, AlbertaAges 50 years+ - NCT07703618Recruiting
Does arm massage and tapping prevent IV irritation?
This study tests whether gentle massage and tapping on your arm near the IV site can lower the chance of irritation (phlebitis) from the IV. If you qualify, you would do simple hand and arm motions for a short time each day while you have the IV.
Bogotá, Bogota D.C.Ages 18–110 - NCT04827316Recruiting
Use CT heart scans to predict outcomes and guide care
This study looks at people who are having a CT scan of their heart because it’s medically needed. Researchers will use the scan results to better predict future cardiovascular outcomes and improve how care decisions are made.
BernAges 18 years+ - NCT05028777Recruiting
People with a heart clot who can join a hospital record study
This study looks at people age 18+ who were found to have a blood clot in the left side of the heart (left ventricular thrombus) on scans between 2013 and 2020. It will compare how different blood-thinner medicines were used and what outcomes occurred.
BernAges 18 years+ - NCT06648954Recruiting
Brain stimulation to improve hand movement in chronic stroke
This study tests whether a brain stimulation technique called high-definition transcranial direct current stimulation (HD-tDCS) can help improve hand and arm movement in people who had a stroke more than a year ago. The stimulation targets the parts of the brain that control movement, and the goal is to see if it can boost recovery when combined with standard therapy.
Hong KongAges Any age - NCT04913727Recruiting
Testing heart scan predictions after mitral valve repair
This trial studies severe secondary mitral valve leaking and uses heart imaging to predict how well the heart and symptoms improve after a less-invasive valve procedure. It may help doctors better forecast who benefits most from this repair.
BernAges 18 years+ - NCT05386277Recruiting
Testing safety of an embolectomy catheter used during clot surgery
This study follows patients who are having surgery to remove a blood clot in an artery or vein and where a specific clot-removal catheter (the LeMaitre TufTex Single Lumen) is used. It aims to confirm how well the device works and monitor safety outcomes.
GenkAges 18 years+ - NCT05546723RecruitingPhase 1
Study drug for multiple myeloma after several prior treatments
This Phase 1 trial tests LMY-920 in people with multiple myeloma that has returned or stopped responding after multiple standard therapies. It’s meant to see if the treatment can work and to better understand its safety and side effects in this situation.
