Does chewing affect artery stiffness in healthy adults?
This study looks at how your oral health and chewing habits might relate to your artery stiffness—a measure of heart health. Researchers will test participants' chewing ability and check their arteries using simple, non-invasive methods.
Innsbruck, TyrolAges 18 years+ - NCT05663216Recruiting
Study of fluid leaks in serious whole-body inflammation
This trial looks at what causes blood vessels to “leak” fluid during a dangerous whole-body inflammation response. It may help doctors understand why some people develop fluid buildup and aim for better monitoring and care in the ICU.
ParisAges 18 years+ - NCT06837870Enrolling by invitation

Boost nerve signaling to improve blood vessel function
This study tests a treatment aimed at increasing “rest-and-digest” nerve activity to improve how blood vessels work, especially in people with vascular oxidative stress. It is designed for African American adults and looks at whether the intervention can improve blood vessel-related health markers.
Nashville, TennesseeAges 18–60 - NCT07198789Recruiting
Low-sugar carbs for better fat and sugar levels
This study tests whether special carbohydrates that release sugar slowly (low glycemic index) can improve your blood fats (triglycerides) and other health markers better than regular whole grains. If you have moderately high triglycerides, this diet swap might help your metabolism and blood vessels.
Bologna, BOAges 18 years+ - NCT07098676Enrolling by invitation
How dialysis affects blood clotting in kidney patients
This trial looks at how hemodialysis changes blood clotting in dialysis patients. It may help doctors understand why some people form clots and how to prevent them.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT07081243Recruiting
A study on a procedure for hard-to-treat high blood pressure
This study looks at a procedure called renal denervation, which uses a device to calm overactive nerves in the kidneys that can drive high blood pressure. It is for people whose blood pressure stays high even with several medications, or who cannot tolerate blood pressure pills.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07042633Recruiting
Gamma brain waves and memory in small vessel disease study
This study looks at how brain waves in certain areas may affect memory in people with cerebral small vessel disease. It uses EEG, a safe way to measure brain activity, along with imaging and thinking tests, to understand why some people have memory trouble.
Beijing, Beijing MunicipalityAges 55–75 - NCT07012668Recruiting
Treatments for heart-brain conditions and post-surgery stroke
This trial is studying different treatments for people who have conditions that affect both the heart and brain, or who have had a stroke or other brain blood vessel problem after heart surgery. The goal is to find out which treatments work best and see what factors affect the results.
BeijingAges 18 years+ - NCT06590532Recruiting
Testing a new X-ray system for vascular surgery
This study compares a new automated X-ray system (mobile hybrid room) with the current standard equipment used during vascular surgery. It aims to see if the new system is more effective and cost-efficient for treating narrowed or widened blood vessels in the belly area.
Besançon, BesançonAges 18 years+ - NCT06985706RecruitingPhase 3
Comparing two treatments for diabetic eye swelling after initial injections
This trial tests whether switching from anti-VEGF injections to a special laser is better than continuing injections alone for people with diabetic macular edema whose central retinal thickness has dropped below 400 microns after the first year of treatment.
BelfastAges 18 years+ - NCT07057245Recruiting
Protein supplement and brain function in older adults
This study tests whether taking a daily protein supplement can improve how your brain works. It is for healthy older adults (ages 60–75) who are overweight but do not have diabetes or take certain medications.
Maastricht, LimburgAges 60–75 - NCT05918783RecruitingPhase 1
Testing a light-activated therapy in peripheral lung tumors
This Phase 1 trial tests padeliporfin, a light-activated medicine, delivered to lung tumors using robotic bronchoscopy. It may help people with small, peripheral lung cancer lesions by targeting the tumor without open surgery.
Baltimore, MarylandAges 18 years+ - NCT06675617Recruiting
Stent treatment for type B aortic dissection
This trial tests if a special stent called the Allay® Aortic Stent can help people with a type B aortic dissection that extends to or past the celiac trunk. It may be an option if you've recently had symptoms and are already scheduled for a standard stent procedure.

Safety and effectiveness of LOBO device for PAVM treatment
This study tests a new device (LOBO™) to block abnormal blood vessels in the lungs called PAVMs. It is for people with HHT or similar conditions, and the device is placed into the vessel to reduce the risk of stroke or bleeding. You may be able to join if you have a suitable PAVM that is large enough and you are not taking blood thinners.

Blood vessel study in very nearsighted eyes
This study uses OCTA, a type of eye scan, to look at the blood vessels in the back of the eye in people who are very nearsighted (high myopia). It aims to understand how high myopia affects the retina's blood supply, which could help with future eye care.

Common questions
- Are there clinical trials for vascular?
- Yes. Clin2 currently lists 591 recruiting vascular 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 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 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.
