Recruiting studies
- NCT04715022RecruitingTeam says not enrollingPhase 1/Phase 2
Vitamin C study for insulin resistance in obesity

Cairo, El WeiliAges 8–16 - NCT06246760Recruiting
Exercise and fitness in healthy adults
This study looks at how breathing, body composition, and heart-lung fitness vary between people who exercise regularly and those who don't. You may qualify if you are generally healthy and can do a treadmill or bike test until you are too tired to continue.
Madrid, Comunity of MadridAges Any age - NCT06062017Recruiting
Potassium, hydration, and heart health in young adults
This study looks at how potassium and hydration affect heart and kidney health in healthy young adults. It may help you understand your own health and contribute to new knowledge about preventing disease.
Auburn, AlabamaAges 18–30 - NCT05951764Recruiting
Checking risk prediction for heart and brain conditions
This study builds or tests computer models that predict risk for heart (cardiovascular) and thinking/memory (neurocognitive) problems using information from people in the general population. It may help improve early detection and planning for care.
ParisAges 45 years+ - NCT05831709Recruiting
Hormone therapy and supervised exercise in menopausal women
This study looks at how hormone replacement therapy and a supervised exercise program may change body composition, heart health risk, and insulin sensitivity in postmenopausal women. It may help participants understand which combination works best for metabolic and cardiovascular health after menopause.
GhentAges 45–65 - NCT05782270RecruitingPhase 4
Blood thinner medicines after bypass surgery with artery unblocking
This trial studies which blood-thinning medicine combination is safest and most helpful after coronary bypass surgery combined with a procedure to unblock the artery (endarterectomy). It focuses on preventing dangerous blood clots while also avoiding excess bleeding.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05316571Recruiting
Lifestyle trial to reduce sitting and improve heart health
This study tests whether breaking up long periods of sitting can improve whole-body cardiovascular (heart and blood vessel) health. You may qualify if you’re currently quite sedentary but otherwise able to walk and climb stairs.
Chapel Hill, North CarolinaAges 30–60 - NCT05617196Recruiting
Virtual pre-surgery rehab for TAVI clinic patients
This study tests a virtual “prehab” program (coaching and preparation before a TAVI heart valve procedure) for people getting treated at the TAVI clinic. It may help you get ready better for the procedure and recovery using phone or online support.
Halifax, Nova ScotiaAges 50–100 - NCT05259150Enrolling by invitation
Health for Hearts program for Black adults
This study is testing a community health program aimed at improving heart health. It is designed specifically for Black adults and looks at whether the program is helpful for people like you.
Tallahassee, FloridaAges 18 years+ - NCT05251324Recruiting
Study effects of hot flushes on heart and blood pressure
This study looks at how hot flushes (also called hot flashes) may affect heart function and blood pressure in postmenopausal people. You may be able to take part if you are not currently using hormone therapy or can stop it for the study.
Minneapolis, MinnesotaAges 40–70 - NCT05334888Recruiting
Study how sex and gut bacteria relate to heart risk
This study follows people over time to understand how sex-related factors and gut bacteria may affect heart and blood-vessel risk. It may help researchers identify who could benefit from earlier prevention, based on personal risk patterns.
BerlinAges 18–50 - NCT03770312RecruitingPhase 4
Testing low/moderate statin use to prevent heart problems in older adults
This study looks at whether taking a low- to moderate-dose statin can prevent first-time heart and stroke problems in people age 70 and older. It may help you lower “bad cholesterol” (LDL) and see if that leads to fewer heart events over time.
SeoulAges 70 years+ - NCT05390892RecruitingPhase 4
Preventing kidney and heart damage in type 2 diabetes
This study tests whether diabetes medicines can help prevent worsening heart and kidney problems in people with type 2 diabetes. You’ll be assigned by chance to one of these medicine types, and your other care will be adjusted for safety.
Huntsville, AlabamaAges 40–80 - NCT03635255Recruiting
Testing heart disease blood markers to predict heart events
This study looks at tiny molecules in your blood to see how they relate to future heart problems in people with coronary artery disease or other cardiovascular disease. If your results suggest higher or lower risk, it may help doctors better predict who could have adverse cardiovascular outcomes.
TaipeiAges 20 years+ - NCT02282748Recruiting
Swiss long-term health study for local residents
This trial is a long-term study that follows people over time to learn about health patterns in specific Swiss areas. Your participation may help researchers better understand long-term health changes and how to improve care.
