This study tests if doing daily breathing exercises with a device can help lower blood pressure and improve blood vessel health. It's for people with higher-than-normal blood pressure who are otherwise healthy.
Minneapolis, MinnesotaAges 18 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 - 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.

Montelukast to improve kidney and blood vessel function in type 1 diabetes
This trial tests whether montelukast, a medicine commonly used for allergies, can improve kidney health and blood vessel function in adults with long-term type 1 diabetes. You may join a treatment group and have kidney and circulation measurements taken over the study period.
Aurora, ColoradoAges 18–80 - NCT07630207Recruiting
Blood Vessel Health Study in Young Adults with Down Syndrome
This research study looks at how blood vessels work in young adults with Down syndrome compared to those without it. By understanding differences in blood vessel function, researchers hope to find ways to improve heart and circulation health for people with Down syndrome.
Las Vegas, NevadaAges 18–35 - NCT06827535Enrolling by invitation
Long-term study of eye changes in glaucoma and high eye pressure
This study tracks changes in blood flow, structure, and vision over time in people with glaucoma or high eye pressure. It aims to understand how these conditions progress, which could help improve future treatment.
Milan, ItalyAges 18 years+ - NCT06786546Enrolling by invitation
Type 1 Diabetes and Blood Vessel Health Study
This study looks at how blood vessels and nerves work in people with Type 1 diabetes compared to healthy volunteers. It may help explain how diabetes affects heart and blood vessel health.
Austin, TexasAges 18–70 - NCT05561361Recruiting
Test treatment for primary aldosteronism and blood vessel function
This trial studies whether a specific treatment (related to spironolactone/aldosterone support) can improve how well your blood vessels work in people with primary aldosteronism. It may help reduce blood pressure risk by improving blood vessel health.
NanchangAges 18–75 - NCT05946785RecruitingEarly Phase 1
Study of blood-vessel changes after gestational diabetes
This early-stage study looks at how “oxidative stress” (cell damage from stress molecules) may affect small blood vessels after pregnancy, especially in people who had gestational diabetes. The goal is to better understand what’s going on and whether these changes could be linked to future health risks.
Iowa City, IowaAges 18–50 - NCT06554340Recruiting
Exercise study for multiple sclerosis with high blood pressure
This study tests if exercise can improve blood vessel health and daily function in people with multiple sclerosis (MS) who also have high blood pressure. It may help you move better and feel better.
Boston, MassachusettsAges 18 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 - NCT05005793RecruitingPhase 4
Alkali treatment to improve kidney graft blood vessel function
This trial tests whether adding an “alkali” treatment (to raise low blood bicarbonate) can improve blood vessel and kidney graft function in people whose kidney transplant is about 1 year old. It may help if you have lower-than-normal bicarbonate levels while on stable transplant and blood pressure medicines.
Aurora, ColoradoAges 18–80 - NCT05659589Recruiting
Using a kidney toxin level to predict heart effects in AKI
This study looks at whether measuring indoxyl sulfate, a substance that can build up when kidneys are injured, can help predict how blood vessels and the heart are affected during acute kidney injury (AKI). It may help doctors understand who is at higher risk of heart-related problems while AKI is happening.
AmiensAges 18 years+ - NCT06127667Recruiting
Balance, brain health, and aging
This study looks at how your brain and blood vessels work together to keep you balanced as you age. It may help researchers understand why some people stay steady on their feet and others don't.

Common questions
- Are there clinical trials for vascular function?
- Yes. Clin2 currently lists 62 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.
