How heart medications affect blood flow in hypertrophic cardiomyopathy
This study looks at how heart medications affect blood flow in people with obstructive hypertrophic cardiomyopathy. You will have a heart MRI before and after starting or adjusting treatment to see how your heart responds.
ViennaAges 18 years+ - NCT07151001Recruiting
AI test for early diabetic eye disease (retinopathy)
This trial uses an AI system to test if it can find early signs of diabetic eye disease (diabetic retinopathy) in people with diabetes. If you have diabetes but no known eye problems, the AI might help catch issues early.

Panvascular disease: diagnosis, prognosis and causes study
This trial studies people with panvascular disease, which means having cholesterol plaque buildup in at least two different blood vessel areas (like heart, brain, or legs). It aims to understand how to diagnose and predict the outcome of this condition, and what causes it.

Ehlers-Danlos syndrome and women's gynecological health
This study uses an online questionnaire to explore how Ehlers-Danlos syndrome (EDS) may affect gynecological health. It compares women with EDS to those without, to better understand any differences.
RouenAges 18–50 - NCT07151521Recruiting
FAPI PET/CT in ANCA vasculitis with lung disease
This study uses a special PET/CT scan (called FAPI) to look at inflammation in people with ANCA-associated vasculitis and interstitial lung disease. It may help doctors see how active the disease is and guide treatment.
ShanghaiAges 18 years+ - NCT07151677Recruiting
Brain stimulation for fatigue and aphasia after stroke
This study tests whether a mild brain stimulation technique can help reduce fatigue and improve language in people who have had a stroke and now have aphasia. It's for those who are at least 6 months past their stroke and still feel tired or have trouble speaking.
Ann Arbor, MichiganAges 18 years+ - NCT07151729Recruiting
Mild Brain Stimulation to Improve Arm Recovery After Stroke
This study tests whether a gentle electrical current applied to the scalp (called tDCS) can help people recover arm movement after a recent stroke. It is for people who have severe weakness in one arm and are still within the first 8 weeks of recovery.
Singapore, SingaporeAges 21–80 - NCT07151755Recruiting
Microneedle injection for retinal artery blockage
This trial tests a tiny needle injection into the artery to dissolve a blockage in the eye's main blood supply. It may help restore vision if the blockage happened within the past week.
Hangzhou, ZhejiangAges 18 years+ - NCT07151768Recruiting
Validating a risk score for lung disease patients with pulmonary hypertension
This study is testing whether a new risk score can better predict outcomes for people who have both chronic lung disease and pulmonary hypertension (high blood pressure in the lungs). If you qualify, the researchers will follow your health over time to see how well the score works.
Philadelphia, PennsylvaniaAges 18–99 - NCT07151976Recruiting
Clot removal and imaging study for heart attack patients
This trial uses a special camera (OCT) to look inside the heart's arteries during a heart attack and compares the images with the actual material removed from the clot. It aims to better understand what causes heart attacks and improve future treatments.
Toyoake, Aichi-kenAges 20 years+ - NCT07153536Recruiting

This trial tests if electrical stimulation of the spinal cord, combined with physical therapy, can improve arm and hand function after a stroke. It is for people who have had a stroke more than 6 months ago and still have significant weakness in one arm.
Pittsburgh, PennsylvaniaAges 22–70 - NCT07154186Recruiting
Triglyceride glucose index in premature heart disease patients
This trial studies whether a simple blood test called the triglyceride glucose index can help doctors understand heart artery disease in younger patients who do not have diabetes. It may lead to better ways to assess heart risk and guide treatment.
SohagAges 18 years+ - NCT07154355Recruiting
Community exercise for heart and lung patients
This study tests whether a community exercise program can improve health in people with heart or lung problems. It may help if you are not already doing regular, structured exercise.
