Telemedicine stroke prevention program for rural elderly adults
This study tests whether using telemedicine (remote health technology) combined with care at a local village clinic can better prevent strokes and manage stroke risk in older adults living in rural areas. Participants will receive ongoing health monitoring and support tailored to their stroke risk factors.
Suqian, JiangsuAges 65 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 - NCT07627009Recruiting
Arm Exercises With and Without Deep Breathing After Heart Surgery
This study tests whether doing arm exercises combined with deep breathing helps recovery after open-heart surgery. Researchers want to see if breathing exercises during movement improves lung function and overall healing in patients recovering in the ICU.
İzmit, KocaeliAges 18 years+ - NCT07625488Enrolling by invitation
Heart Disease Risk Follow-up Study for Former Athletes
This study follows up with people who participated in a heart-health study between 2012 and 2014. Researchers will use heart imaging and exercise tests to check your cardiovascular health and learn more about heart disease risk in athletes.
NijmegenAges 45 years+ - NCT07624630Recruiting
Brain Activity and Walking After Stroke
This study examines how your brain works when you walk and think at the same time after stroke. Researchers will use brain imaging to understand this process, which could help develop better rehabilitation strategies.
Solna, Stockholm CountyAges 18 years+ - NCT07620808Enrolling by invitation
Medically-Tailored Meals and Heart Health Study
This study tests whether personalized meal plans designed by doctors can help people with type 2 diabetes and high blood pressure improve their heart health. You'll receive specially prepared meals for 8 months and answer questions about your health.
New York, New YorkAges 20 years+ - NCT07622212Recruiting
Comparing devices to clear leg blood clots quickly
This trial compares different mechanical devices used to remove recent blood clots from the deep veins in your leg (iliac and femoral veins). The goal is to restore blood flow and prevent long-term complications like chronic pain and swelling.
ShanghaiAges 18–85 - NCT07624513RecruitingPhase 3
Drug combination with planned stem cell transplant for newly diagnosed myeloma
This trial tests a combination of study drugs as the first treatment for newly diagnosed multiple myeloma, followed by maintenance based on your risk and response. It aims to improve outcomes while allowing some patients to postpone or avoid a stem cell transplant.
Boston, MassachusettsAges 18–75 - 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+ - 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 - NCT07621367Recruiting
Gut oxygen therapy for bowel problems from low oxygen
This trial tests a treatment that delivers oxygen directly to the gut through a small tube. It is for people with long-term heart failure or sleep apnea who also have belly pain, bloating, constipation, or diarrhea.
Nanjing, JiangsuAges 18 years+ - NCT07624396Recruiting
Brain protein levels and heart-related strokes
This study looks at a brain protein called BDNF in people who've had a stroke caused by a clot from the heart. Researchers want to understand if BDNF levels can help explain why some strokes happen this way and may help doctors prevent future strokes.
DijonAges 18 years+ - NCT07620626Recruiting
Study of Woven EndoBridge for Brain Aneurysm Treatment
