Atrial Fibrillation Stroke Recovery Study
This study follows people who had a stroke linked to atrial fibrillation (an irregular heartbeat) and are in a rehabilitation program. Researchers want to see how recovery goes and what helps patients improve.
BarcelonaAges 18–99 - NCT07252830Recruiting
Finding hidden heart risk with extra imaging tests
This study looks at whether using special scans of the heart and neck arteries can better find people at very high risk for heart problems, compared to just using a standard risk score. You may be eligible if you have high cholesterol and are seeing a heart doctor.
PoitiersAges 40–80 - NCT07249671Recruiting
Rope skipping for kids' heart and lung fitness
This study tests if rope skipping can improve heart and lung fitness in healthy children ages 6 to 12. It may help kids get more active and build endurance.
Chak Four Hundred Fifty-four, Punjab ProvinceAges 6–12 - NCT07250035RecruitingPhase 3
Chinese herb trial for brain bleed linked to amyloid angiopathy
This trial tests a traditional Chinese medicine called Jiedu Huayu to see if it helps people recover from a brain bleed caused by a condition where proteins build up in blood vessel walls (cerebral amyloid angiopathy). The goal is to improve outcomes without surgery.
BeijingAges 50–90 - NCT07254195Recruiting
Home rehab program for arm recovery after stroke
This study tests a home-based program using a device called MindMotion GO to help people who have had a stroke improve arm movement. If you had a first stroke more than a month ago and still have trouble using your arm, this program may help you practice movements at home.
Saint-Genis-Laval, LyonAges 18–85 - NCT07257367Recruiting
Pressure sensing sheath vs. traditional blood pressure monitoring in wrist procedures
This trial compares a new pressure-sensing sheath that monitors blood pressure during wrist-artery procedures to the traditional method. It aims to see if the new device works just as well or better, and is for patients who are already scheduled for a planned (not emergency) procedure needing continuous blood pressure monitoring.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07253909Enrolling by invitation
Arm function in heart failure with ICD or CRT devices
This study looks at how well people with heart failure and certain heart devices (ICD or CRT) can use their arms and hands. It aims to understand if these devices affect upper body function.
Ankara, SamanpazarıAges 18 years+ - NCT07258524Recruiting
Vasculitis PET scan trial for heart disease risk
This trial uses a special PET scan to look at inflammation in blood vessels and check heart disease risk in people with active ANCA-associated vasculitis (AAV). It may help doctors understand how to better manage heart health during treatment.
EdinburghAges 18 years+ - NCT07250529Recruiting
Comparing two pacemaker pacing methods for heart block
This study compares two types of pacemaker pacing methods in people with heart block and normal heart pumping function. It looks at how often short bursts of fast heart rhythm occur in the upper heart chambers, which may help improve long-term heart health.
PátraiAges 18 years+ - NCT07257107Recruiting
Vagus nerve stimulation plus robot training for stroke recovery
This trial tests if combining a gentle ear nerve stimulation device with robot-assisted arm training can improve arm function in people who had a stroke more than six months ago.
Istanbul, IstanbulAges 18–70 - NCT07250958Recruiting
Testing dome-only coiling for severe aneurysm bleeding
This trial tests a specific way of treating a brain aneurysm that has caused a severe bleed (subarachnoid hemorrhage). Instead of coiling the whole aneurysm, doctors will only coil the dome part. The goal is to see if this simpler approach helps patients who are very sick from the bleeding.
Louisville, KentuckyAges 18 years+ - NCT07254572RecruitingPhase 4
Comparing diabetes drugs for heart health in prediabetes
This trial tests whether certain diabetes medications can help prevent worsening of heart disease in people who have prediabetes (higher than normal blood sugar, but not yet diabetes). It may be a good fit if you have known coronary artery disease and prediabetes.
WarsawAges 18–80 - NCT07251140Recruiting
Swallowing study with a new microphone device
This study tests a new microphone device to see if it can help find swallowing problems in people who have had a stroke. If you are already scheduled for a swallowing test, you may be able to take part.
Atlanta, GeorgiaAges 40–85 - NCT05692882Recruiting
Registry for stent treatment in narrowed brain arteries in China
This study records outcomes for people with significant narrowing in brain arteries who have treatment using a drug-eluting stent. It may help doctors understand how well this approach works and what risks or benefits to expect.
ChenzhouAges 18–85 - NCT06560372Recruiting
Bleeding after head injury and brain blood vessel narrowing
This study looks at whether moderate to severe traumatic brain injury with bleeding around the brain can lead to a complication called cerebral vasospasm (narrowing of brain blood vessels). It's being done at Martinique University Hospital to understand how often this happens and how it affects recovery.
Fort-de-FranceAges 18 years+ - NCT06525012Recruiting
Study on recovery after brain aneurysm bleeding in Martinique
This study looks at what happens to people who are hospitalized in Martinique after a brain aneurysm bursts. The goal is to understand recovery and outcomes better.
Fort-de-FranceAges 18 years+ - NCT06153589Recruiting
Music therapy for leg ulcer pain relief
This trial tests whether listening to music during wound cleaning can reduce pain for people with leg ulcers caused by vein or artery problems. It aims to make the procedure more comfortable.
Fort-de-FranceAges 18 years+ - NCT03622359Recruiting
Imaging blood flow in leg artery disease using a scan
This study uses a special “radiotracer” scan to look at how well blood flows through the arteries in the legs. It may help researchers better understand circulation problems from peripheral artery disease.
Columbus, OhioAges 18 years+ - NCT06904768Recruiting
Shoulder sling effect on balance and walking after stroke
This study tests whether using a shoulder sling helps improve balance and walking ability in people who had a stroke within the last 6 months and have one-sided arm weakness. It aims to see if the sling can make moving around safer and easier.
Koropí, AtticaAges 18 years+ - NCT05479448Recruiting
Tracking what predicts response in new PMR or GCA
This study looks at people newly diagnosed with polymyalgia rheumatica (PMR) or giant cell arteritis (GCA) and uses their health and treatment information to learn what predicts how well treatment works. It may help your care in the future by improving which patients respond best and how.
BaselAges 18 years+ - NCT05708807Recruiting
Follow-up study of recovery after first-time stroke in Gothenburg
This study tracks how people recover after their first-ever stroke (either blocked artery stroke or bleeding in the brain). It may help doctors better understand recovery patterns and what support could work best over time.
GothenburgAges 18 years+ - NCT05903170Recruiting
Shock energy study for heart rhythm conversion in atrial fibrillation
This trial tests whether using a specific “shock energy” during electrical cardioversion works safely and effectively for people with persistent atrial fibrillation. You might be eligible if your cardioversion is planned (not an emergency) and your doctors determine you can safely take blood thinners.
Wellington, Wellington RegionAges 18 years+ - NCT05649904Recruiting
Study for adults needing brain fluid drainage after brain bleeding or infection
This study looks at patients age 18+ who need a procedure to drain brain fluid after certain brain bleeds (like intraventricular or subarachnoid bleeding, or chronic subdural bleeding) or after ventriculitis. It aims to better understand and improve care for people with these serious conditions.
Columbus, OhioAges 18 years+ - NCT06857058Recruiting
Drug-eluting stent for brain artery narrowing
This trial tests a drug-coated stent to treat severe narrowing in brain arteries. It may help reduce the risk of stroke in people with hardened arteries in the brain.
