This study looks at how a heart valve procedure called TAVI affects the bacteria in your gut. It may help doctors understand how the procedure impacts your overall health.
AthensAges Any age - NCT07052435Recruiting
Measuring pressure and flow during leg artery treatment
This study looks at how well blood flows through leg arteries after using a balloon to open blockages. It uses special measurements to check if the treatment fully restores blood flow, which may help guide future treatments.
PátraiAges Any age - NCT07052799RecruitingPhase 3
Should you pause aspirin before a colonoscopy?
This trial compares stopping aspirin versus continuing it before a colonoscopy in people who take aspirin to prevent heart problems. The goal is to find out which approach is safer and works best.
Hong KongAges 18 years+ - NCT07053917RecruitingPhase 1
Psilocybin therapy for stroke recovery
This trial tests whether a medicine called psilocybin (a psychedelic compound) can help people who had a stroke more than a year ago. It aims to see if the therapy can improve healing and flexibility in the brain.
Baltimore, MarylandAges 18 years+ - NCT07054060Recruiting
Surgery vs. Stenting for Recent Stroke Symptoms from a Narrowed Carotid Artery
This trial compares two procedures—surgery to remove plaque from a carotid artery or placing a stent to widen the artery—to see which is better for people who recently had warning signs or a small stroke due to a severe blockage. The goal is to find the safest and most effective way to prevent future strokes.
ParisAges 18 years+ - NCT07054073Recruiting
HCMR Re-Imaging: MRI follow-up for HCM patients
This study uses MRI scans to re-examine people with hypertrophic cardiomyopathy (a thickening of the heart muscle) who were part of the original HCMR study. It compares different types of HCM to learn more over time.
Evanston, IllinoisAges 18–65 - NCT07054424Recruiting
TMS and bimanual therapy for arm recovery after stroke
This trial tests if combining repetitive magnetic brain stimulation (rTMS) with two-handed therapy can improve arm function after a first-time stroke. It may help people who have weakness or difficulty using one hand due to a stroke within the past year.
TaoyuanAges 40–80 - NCT07054489Recruiting
Genetic guided beta blocker therapy for heart failure
This trial tests whether a genetic test can help doctors choose the best beta blocker for people with heart failure who have mildly reduced pumping function. It aims to improve treatment by matching the drug to your genetic profile.
Detroit, MichiganAges 18–89 - NCT07055152Recruiting
Eye scan to understand heart attack risk in MINOCA patients
This study uses a special eye scan (OCTA) to look at tiny blood vessels in the eye and see if they can help predict outcomes for people who had a heart attack without blocked arteries (MINOCA). It compares these patients to others with typical heart attacks and healthy people.
Pisa, PisaAges Any age - NCT07055919Recruiting
Assist system for mitral valve clip procedure
This study is testing a new assist system to help doctors perform a minimally invasive procedure (MitraClip) that clips the leaky mitral valve without open-heart surgery. It is for people with severe mitral regurgitation who cannot safely have surgery or choose not to.
Xiamen, FujianAges 18 years+ - NCT07055945Recruiting
Visual-motor training for arm function after stroke
This trial tests if a type of training that combines eye exercises with arm movements can help people who have had a stroke regain better use of their affected arm.
Ankara, TürkiyeAges 18–75 - NCT07056049Recruiting
Extra arm exercises after stroke
This trial tests whether adding more arm exercises early after a stroke helps people recover arm and hand movement. If you qualify, you would get extra motor training in addition to your regular therapy.
OfakimAges 18 years+ - NCT07056348Recruiting
Brain stimulation to improve movement in Parkinson's or tremor
This study tests brain stimulation in a region called VOP/VIM to see if it can improve motor function. It is for people with movement disorders who are already getting deep brain stimulation (DBS) surgery.
Pittsburgh, PennsylvaniaAges 18–80 - NCT07056361Recruiting
Testing brain stimulation for better movement in tremor and Parkinson's
This study tests whether stimulating specific brain areas (VOP/VIM) during deep brain stimulation surgery can improve movement and muscle control. It includes people with essential tremor or Parkinson's disease who are already scheduled for this surgery.
Pittsburgh, PennsylvaniaAges 18–75 - NCT07057297Recruiting
Tracking Artery Narrowing After Carotid Surgery
This study follows patients who have had carotid artery surgery to see if the artery narrows again. It helps doctors understand how well the surgery works over time.
PragueAges 18–90 - NCT07057466Recruiting
AI heart check for hidden valve, pressure, or pump problems
This study uses an artificial intelligence (AI) program to read your ECG (a heart tracing) and detect early signs of heart failure, high blood pressure in the lungs, or valve disease before you have symptoms. The goal is to see if AI can catch these problems early.
BristolAges 18–90 - NCT07057544Recruiting
