Kelowna, British ColumbiaAges Any age - NCT07229261Recruiting
MitoQ for blood vessel health in preeclampsia
This trial tests whether a supplement called MitoQ improves blood vessel function in pregnant people with preeclampsia. It may help manage blood pressure and reduce complications.
Milwaukee, WisconsinAges 18–50 - NCT07221448Recruiting
Comparing salt versus potassium education for healthier blood vessels
This study compares two education programs — one focused on lowering sodium (salt) and one on boosting potassium — to see which improves blood vessel health. It's for people who eat a lot of salt but not enough potassium, and who generally have a healthy heart and kidneys.
Tallahassee, FloridaAges 18–45 - NCT07223437Recruiting
Restricted exercise for peripheral artery disease study
This study tests a new type of exercise that uses a blood-flow restriction cuff to see if it helps people with leg pain from blocked arteries. If you have stable claudication (leg pain when walking) and have been referred to cardiac rehab, you may qualify.
Knoxville, TennesseeAges 18 years+ - NCT06214429Recruiting
Shear wave test for carotid plaque stiffness
This trial uses a special ultrasound technique called shear wave elastography to measure how stiff fatty deposits (plaques) are in your neck arteries. It aims to see whether plaque stiffness can help doctors better understand your stroke risk.
Botucatu, São PauloAges 18 years+ - NCT05566002Recruiting
AI review of test results for pulmonary hypertension
This trial uses an artificial intelligence tool to look at results from tests used to evaluate pulmonary hypertension. It may help doctors make sense of your past test results, especially heart and lung evaluation results.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07214376Recruiting
Nerve ablation for pulmonary hypertension from left heart disease
This trial tests a device that uses a catheter to deliver energy to nerves around the pulmonary arteries, aiming to reduce high blood pressure in the lungs caused by left heart failure. It is for people with ongoing heart failure symptoms despite optimal medications.
Tucson, ArizonaAges 18–85 - NCT06460142Recruiting
Biomarker study for giant cell arteritis and polymyalgia rheumatica
This study is looking for biomarkers (biological clues) in people with newly diagnosed or flaring giant cell arteritis (GCA) or polymyalgia rheumatica (PMR). Participating may help researchers find better ways to diagnose and monitor these conditions.
Bonn, North Rhine-WestphaliaAges 18 years+ - NCT06010511Recruiting
White matter changes and brain fluid study in older adults
This study uses special MRI scans to look at white matter changes in the brain (often linked to memory problems). It may help doctors understand more about these changes in older adults visiting memory or geriatric clinics.
LeidenAges 65 years+ - NCT07209527Enrolling by invitationEarly Phase 1
Truway diagnostic tools in primary care
This trial tests new diagnostic tools that doctors can use in primary care. Researchers want to see if these tools help find the right diagnosis faster and more accurately.
New York, New YorkAges Any age - NCT07211035Recruiting
Study of a device to help create a working dialysis access
This study tests a device that widens your vein before creating the connection used for dialysis. The goal is to help the access mature faster and work better for your treatments.
Boston, MassachusettsAges 18 years+ - NCT07205003Recruiting
Artery stiffness test for memory disorders
This study looks at how the stiffness of your carotid artery (the main artery in your neck) relates to memory problems. It involves a brain MRI that you may already have planned, and results could help doctors better understand certain types of dementia.
RouenAges 70 years+ - NCT07206238Recruiting
Orbital blood vessel inflammation in optic nerve disease
This study uses MRI scans to look at inflammation in blood vessels around the eye in two conditions: giant cell arteritis (GCA, a type of blood vessel inflammation) and ischemic optic neuropathy (a condition where the optic nerve doesn't get enough blood). The goal is to better understand how inflammation affects the optic nerve and vision, which could help guide future treatments.
