Using a special camera to check leg circulation
This study tests a special camera (SnapshotNIR) that takes pictures of blood flow in your legs while you move them into different positions. It may help doctors better understand your circulation and diagnose peripheral artery disease (PAD) without needles or dye.
San Antonio, TexasAges 35–99 - NCT06516588RecruitingPhase 2
Brain stimulation for memory and thinking after stroke
This trial tests if a gentle brain stimulation technique called tDCS can help improve memory and thinking in people who have had a stroke. It is for those who are still in the early recovery phase (between 10 days and 5 months after their stroke) and have some ongoing cognitive problems.
Oklahoma City, OklahomaAges 18–99 - NCT07715656Recruiting
Middle-meningeal-artery embolization for chronic subdural hematoma
This trial studies a procedure called middle-meningeal-artery embolization, which blocks the blood supply to a chronic subdural hematoma (a slow-growing blood collection around the brain). It compares outcomes in people with one-sided versus both-sided bleeds, and aims to see if this less invasive treatment can help reduce the need for surgery or improve recovery.
Burlington, MassachusettsAges 18 years+ - NCT07719660Recruiting
Wearable blood pressure monitor comparison study
This study compares a wearable blood pressure monitor to standard measurements. It needs people whose arm can be used for a cuff and who can give consent, and some participants are in the ICU.
Dresden, SaxonyAges 21–85 - NCT07718997RecruitingPhase 1
Social skills training for people with sex chromosome differences
This trial tests a social management training program for adults with sex chromosome aneuploidies (SCA). The goal is to see if it can help improve social skills and daily life. It is a small feasibility study to prepare for larger future trials.
OsloAges 16–65 - NCT07722910Recruiting
Iris blood flow in diabetic neovascular glaucoma
This study uses a special camera (OCTA) to look at blood flow in the iris of people with or without type 2 diabetes and diabetic neovascular glaucoma. The goal is to understand how blood flow changes in this eye condition.
Jinan, ShandongAges 18 years+ - NCT07716475Recruiting
Home gait training with a hip robot for stroke recovery
This trial tests a wearable hip robot to help people with stroke walk better at home. It may improve your gait and daily movement.
Yongin-si, Gyeonggi-doAges 19–80 - NCT07723300Recruiting
Self-guided arm therapy for stroke recovery
This trial tests a self-supervised arm therapy program for people who had a stroke at least two weeks ago. It aims to improve use of the weaker arm through intensive practice at home.
Columbus, OhioAges 18–85 - NCT07716488Recruiting
Screening for high cholesterol in children with chronic conditions
This study screens children and teens with certain chronic conditions (like heart defects or inflammatory bowel disease) for early signs of high cholesterol or other lipid problems. The goal is to find and manage these risks sooner.
JenaAges 6–18 - NCT07719387Enrolling by invitation
Vagus nerve stimulation to boost thinking and learning after stroke
This study tests if vagus nerve stimulation, delivered through an implanted device, can help improve thinking and learning in people who have had a stroke. You would use the device at home for six weeks.
Stony Brook, New YorkAges 22 years+ - NCT07715279RecruitingPhase 2
Vericiguat for slowing aortic valve calcium buildup
This trial tests if the drug vericiguat can slow down the buildup of calcium in the aortic valve, which causes it to narrow and stiffen. If you have mild-to-moderate aortic valve stenosis and meet the other criteria, this study may help protect your valve from getting worse.
Chengdu, SichuanAges 35–80 - NCT07722637Recruiting
Cardiac rehab's effect on cell health in heart disease
This study looks at whether a heart rehab program can affect a type of cell damage (ferroptosis) in people who recently had heart artery disease. It could help show why rehab is good for recovery.
Kayseri, KayseriAges 18–75 - NCT07720570Enrolling by invitation
Bleomycin electrosclerotherapy for slow-flow vascular malformations
This trial tests a treatment called bleomycin electrosclerotherapy for people with slow-flow vascular malformations (abnormal blood vessels that do not flow quickly). The goal is to see if this treatment works well and is safe for these conditions.
Copenhagen, Capital Region of DenmarkAges 2 years+ - NCT07717710RecruitingEarly Phase 1
Heart rate medication for healthy adults during exercise
This study tests a pill called ivabradine that lowers heart rate, to see how it affects healthy adults when they exercise. Participation requires two supervised exercise sessions.
Vancouver, British ColumbiaAges 19–79 - NCT07722897Recruiting
Monitoring brain activity during emergency intubation
This study tests whether monitoring brain activity (using a sensor on the forehead) during emergency intubation helps prevent unstable blood pressure or heart rate. It is for adults who need a breathing tube placed quickly in the emergency room.
AntalyaAges 18 years+ - NCT07719075Recruiting
Norepinephrine dose for low blood pressure during emergency belly surgery
This trial tests whether a 5 microgram or a 10 microgram dose of norepinephrine works better to treat low blood pressure that happens after starting anesthesia or during emergency abdominal surgery. It may help doctors choose the right dose to keep your blood pressure stable.
Cairo, Cairo GovernorateAges 21–65 - NCT07722793Enrolling by invitation
EVAR study: heart and artery changes after aneurysm repair
This study looks at how the heart and large arteries change after endovascular repair of an abdominal aortic aneurysm (a bulge in the main artery in your belly). It may help doctors understand if the repair improves heart function and vessel stiffness over time.
OsijekAges 18 years+ - NCT07719517Recruiting
Morning activities to boost mood after stroke
This study tests if doing simple, guided activities in the morning can help improve your mood after a stroke. If you often feel down and have trouble getting going in the morning, this program might offer a way to feel better.
Hong KongAges 18 years+ - NCT07721701Recruiting
Digital Dementia Registry for Bavaria
This study follows people with mild cognitive impairment or dementia and their family caregivers over time. It aims to learn more about how these conditions progress and how to improve care, especially for those living in Bavaria.
AschaffenburgAges Any age - NCT07718113Recruiting
Exercise Snacking and Heart Health
This study tests whether short 'exercise snacks' (brief bursts of activity throughout the day) can improve your heart and metabolic health. It's for people who are currently not very active and want to see if small, frequent exercise breaks can make a difference.
River Falls, WisconsinAges 18–60 - NCT07719894RecruitingPhase 4
Preventing heart problems in type 2 diabetes with cilostazol and aspirin
This trial tests whether taking cilostazol and aspirin together can help prevent heart attacks, strokes, and other cardiovascular events in people with type 2 diabetes who have early signs of artery disease or metabolic syndrome. It aims to see if this combination is more effective than aspirin alone.
Seongnam-si, Gyeonggi-doAges 19 years+ - NCT07721649Recruiting
Flu shot during hospital stay for heart patients
This study checks if giving a flu shot to heart patients while they are in the hospital helps prevent heart problems later. It tests whether the flu shot can reduce the risk of further heart events.
