Remote ischemic conditioning for high blood pressure
This trial tests if a simple, non-invasive treatment called remote ischemic conditioning (briefly restricting blood flow to an arm) can safely lower blood pressure in people with essential hypertension. It is for adults aged 30-75 whose blood pressure is consistently high despite standard care.
Changchun, JilinAges 30–75 - NCT07731490Recruiting
Early detection and treatment of heart failure
This trial tests if a medication can prevent heart failure in older adults who are at risk. It is for people aged 65 or older who are having certain heart procedures or a major surgery.
ViennaAges 65 years+ - NCT05283356RecruitingPhase 4
Ticagrelor or aspirin after heart valve replacement
This trial compares two blood thinners (ticagrelor and aspirin) to see which one works better at preventing blood clots after a less-invasive heart valve replacement (TAVI). It is for people with severe aortic stenosis who also have diabetes, heart disease, or artery disease.
Vigo, PontevedraAges 18 years+ - NCT07732244Recruiting
Testing a wireless brain oxygen monitor in the NICU
This study is testing a new wireless device that monitors oxygen levels in the brain. It is for babies already using a similar wired monitor, to see if the wireless version works just as well.
Montreal, QuebecAges Any age - NCT07024563RecruitingPhase 3
Testing ravulizumab for kids with IgA nephropathy
This study tests a drug called ravulizumab for children aged 2 to under 18 with IgA nephropathy, a kidney condition. It aims to see if the drug can help protect the kidneys and reduce protein in the urine.
Palo Alto, CaliforniaAges 2–18 - NCT07730827Recruiting
Community program for better heart failure care
This study tests whether a program that connects you with community health workers and your care team can help you manage heart failure better. It looks at things like your living situation, medical needs, and social support to make your care more fair and personalized.
Rochester, MinnesotaAges 18 years+ - NCT07731087Recruiting
Stem cell secretion therapy for thinking recovery after stroke
This study tests whether a therapy made from stem cell secretions can help improve memory and thinking after an ischemic stroke. It is for people who had a clot-related stroke in the past 3 months and now have mild to moderate cognitive issues.
Makassar, South SulawesiAges 40–75 - NCT07613294RecruitingPhase 3
Testing lepodisiran to reduce heart plaque buildup
This study tests whether a new medicine called lepodisiran can shrink plaque in heart arteries for adults with high Lp(a) (a type of cholesterol linked to heart disease) who have had a heart event or are at serious risk. The trial uses CT scans to monitor changes in your arteries.
