Light therapy for blood pressure in people taking losartan
This study tests whether a special light therapy (called photobiomodulation) applied to your arms can help lower blood pressure and improve how your blood vessels work. It is for people who already take blood pressure medicine and have their blood pressure under control.
São Paulo, São PauloAges 18–65 - NCT06823570Recruiting
Exercise and blood pressure medicine for better blood vessels
This study is testing whether a combination of blood pressure medication and a supervised exercise program can improve the health of your blood vessels. It's for people with mild to moderate high blood pressure who are not already on medication.
Düsseldorf, DüsseldorfAges 18 years+ - NCT07177781Recruiting
Blueberries and brain function in older adults
This study tests whether eating wild blueberries every day for several weeks can improve brain function in people ages 60 to 75 who are overweight or obese. You'll eat blueberry powder or a placebo and have memory and thinking tests before and after.
Maastricht, LimburgAges 60–75 - NCT06034509Recruiting
Thinking and blood vessel health after head injury
This study looks at how a past traumatic brain injury (TBI) might affect your thinking skills and blood vessel health over time. You may be eligible if you had a TBI at least 3 years ago and have already completed an earlier evaluation at the National Intrepid Center of Excellence (NICoE).
Bethesda, MarylandAges 18–74 - NCT07422220Recruiting
Walnuts and brain health: a long-term study
This study tests whether eating walnuts every day for a long time can help keep your brain healthy as you age. It is for middle-aged and older adults who carry extra weight around their belly but are otherwise generally healthy.
Maastricht, LimburgAges 45–75 - NCT05468255Recruiting
Study how stopping exercise affects blood sugar and blood vessels
This study looks at what happens to blood sugar levels and blood vessel health when active adults stop exercising. It may help doctors understand how quickly these changes can happen and who may be most affected.
Norfolk, VirginiaAges Any age - NCT06985394Recruiting
Blood vessel health and stress in emergency responders
This study looks at how shift work affects blood vessel function and oxidative stress in emergency medical responders. It may help understand why first responders have higher risk for heart problems.
Newark, DelawareAges 20–40 - NCT07244809Recruiting
Study on stress history and blood vessel health in young adults
This study tests whether early-life stress affects blood vessel function in young adults by looking at a type of cell stress called oxidative stress. It involves measuring how well your blood vessels work and may help understand why some people have higher heart risks.
Iowa City, IowaAges 18–29 - NCT05228262Recruiting
Testing blood-vessel function and muscle strength in osteoporosis
This study looks at how well your blood vessels work and how strong your muscles are, in women after menopause with osteoporosis. You may be asked to start standard osteoporosis treatment, and the researchers will study pain and changes related to vascular function and sarcopenia (loss of muscle and strength).
Clermont-FerrandAges 50 years+ - NCT07630207Recruiting
Blood vessel health in adults with Down syndrome
This study looks at how blood vessels work in adults with Down syndrome compared to those without Down syndrome. It aims to understand heart health better and may help improve future care.
Las Vegas, NevadaAges 18–35 - NCT07594392Recruiting
Heart Health Study for Cancer Survivors
This study looks at how cancer treatments affect the heart and blood vessels in adults who survived childhood cancer. Researchers will use imaging tests to find early signs of heart problems so they can help prevent serious complications like heart attacks or strokes.
Memphis, TennesseeAges 18 years+ - NCT06151015Recruiting
Dietary nitrate and calorie restriction for brain health
This study tests whether eating foods rich in dietary nitrates (like beets) combined with reducing calorie intake improves memory and blood vessel function in older adults.
Nottingham, NottinghamshireAges 60–75 - NCT05188079Recruiting
Test whether quick nitrate supplements change blood vessel function
This study checks how an acute (short-term) nitrate supplement affects how well your blood vessels work. It may help researchers understand whether these effects differ among Hispanic, Black, and White participants, in otherwise healthy adults.
Austin, TexasAges 18–65 - NCT07312409Recruiting
Taurine for long COVID vascular health
This study tests whether taking taurine supplements can improve blood vessel function and help with dizziness or fainting caused by long COVID.

Boulder, ColoradoAges 40 years+ - NCT07172425Recruiting
Testing nitrate-enriched foods for blood vessel health
This study tests whether adding nitrate (a natural compound found in leafy greens and beets) to foods can boost the body’s levels of nitric oxide, which helps blood vessels relax and improve blood flow. If you’re a healthy adult, you may be able to join to help researchers learn how diet affects your blood vessels.
LondonAges 18–60 - NCT07125001Recruiting
Mango study for Hispanic/Latino teens' health

Common questions
- Are there clinical trials for vascular function?
- Yes. Clin2 currently lists 63 recruiting vascular function studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a vascular function trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a vascular function trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
