New procedure vs standard pill for adrenal-related high blood pressure
This study tests if a new procedure (blocking tiny adrenal arteries) works as well as a standard pill (spironolactone) for lowering high blood pressure caused by too much aldosterone from both adrenal glands. It is designed for people whose high blood pressure is due to idiopathic hyperaldosteronism.
Beijing, Beijing MunicipalityAges 15–60 - NCT07329075Recruiting
Soft robot for hand rehab after stroke

Hong KongAges 18 years+ - NCT07332468Recruiting
Smartphone-based heart health program versus usual care
This study tests whether a digital remote management program (using a smartphone) helps people at high risk for heart disease or stroke make healthier lifestyle choices and better manage their medications, compared to usual care. It is for adults 35+ who are not already on advanced heart treatments.
BeijingAges 35 years+ - NCT07334028Recruiting
Timing of infrared imaging for varicose veins
This study uses a special camera to take pictures of your leg veins at different times to find the best moment for imaging. It may help improve how varicose veins are diagnosed.
Guildford, SurreyAges 18 years+ - NCT07328152Recruiting
European health data study for rare diseases
This trial combines health information from European research groups to study rare diseases. It looks at data from people who agreed to participate in these studies, which may help find better ways to diagnose or treat rare conditions.
BrestAges Any age - NCT07333222Recruiting
Testing a suit to help movement after stroke or MS
This study tests whether wearing a special suit (Mollii) that sends gentle electrical pulses to the body can help improve movement, balance, and daily life for people who have had a stroke or have multiple sclerosis. The suit is meant to calm overactive muscles and help you move better.
Kaposvár, Somogy CountyAges 18–99 - NCT07330882Enrolling by invitation
Heart health app study for coronary disease
This study tests a smartphone app to help people with coronary heart disease manage their health. You may be eligible if you have been diagnosed with coronary heart disease, can use a smartphone, and have no serious health issues that would limit exercise.
BengbuAges 18–80 - NCT07326605Enrolling by invitation
Heart MRI study for heart failure with preserved pumping function
This trial uses a special heart MRI to create pressure-volume loops in people with heart failure who have a normal pumping strength (ejection fraction of 50% or higher). It aims to better understand heart function and could help guide future treatments. You may qualify if you have heart failure symptoms and specific heart structure or function changes.
Ages 18 years+ - NCT07325968Enrolling by invitation
Heart MRI Study for Myocarditis and Heart Inflammation
This study uses a special heart MRI to look closely at inflammation in the heart muscle. It helps doctors better understand and treat myocarditis and inflammatory cardiomyopathy.
Ages Any age - NCT07332234Recruiting
Optic nerve ultrasound for brain inflammation and pressure
This study uses a quick ultrasound of the optic nerve to help doctors detect swelling or pressure in the brain. It may help people with suspected meningitis, encephalitis, stroke, or brain tumors decide on the best treatment earlier.
Bucharest, BucharestAges 18–60 - NCT07329699Recruiting
AI-Guided Heart Artery Pressure Test vs Standard Test
This study compares a new artificial intelligence (AI) method to measure blood flow in your heart arteries (called Medipixel FFR) with the standard invasive method. If you are scheduled for a heart angiogram or stenting and have a moderate blockage (40-90% narrowing) that doctors are unsure about, this AI tool may help decide the best treatment for you.
Seoul, Select StateAges 19 years+ - NCT07332897Enrolling by invitation
Neck exercises plus motor relearning after stroke
This study tests whether adding neck stabilization exercises to a standard motor relearning program helps people who have had a recent stroke improve their movement and function better than the motor program alone.
Lahore, Punjab ProvinceAges 35–65 - NCT07333079Recruiting
Rehabilitation with biofeedback for stroke recovery
This study tests if adding biofeedback to standard rehabilitation improves hand and arm function after a stroke. Biofeedback uses sensors to show you how your muscles are working, helping you regain movement.
RzeszówAges 45–80 - NCT07332741RecruitingPhase 2
Food as medicine for better blood pressure
This study tests a program that provides healthy food and support to help people with high blood pressure and a BMI of 30 or higher eat better and control their blood pressure. If you join, you'll get guidance on the DASH diet (a heart-healthy eating plan) and text messages to help you stay on track.
Chicago, IllinoisAges Any age - NCT07327593Recruiting
Exercise and pain relief in stroke survivors
This study looks at whether exercise can reduce pain sensitivity in people who have had a stroke and in healthy individuals. Participants will pedal on a stationary bike to see how their pain perception changes.
Madrid, MadridAges 18 years+ - NCT07325942Recruiting
Low vs high volume high-intensity interval training for heart failure
This study compares two different types of high-intensity interval exercise programs (one shorter, one longer) in people with chronic heart failure. It aims to see which program improves heart health and daily function more.
Cairo, Giza GovernorateAges 18 years+ - NCT07333729Recruiting
Spinal anesthesia's effect on baby's nervous system during C-section
This study looks at how spinal anesthesia during a planned C-section may affect the baby's autonomic nervous system, which controls things like heart rate and breathing. It aims to help doctors better understand how to keep both mother and baby safe.
