This study tests a special imaging camera that measures blood flow in your leg before, during, and after surgery to improve the artery. The goal is to help doctors see in real time whether the surgery is working properly.
Leiden, South HollandAges 18 years+ - NCT03717792Recruiting
Check how doctors follow up vascular liver disease
This study focuses on people who have vascular liver disease and aims to evaluate follow-up care and non-invasive ways to assess it. It may help improve how safely and accurately doctors monitor your liver without invasive procedures.
BonnAges 18–100 - NCT05967728Enrolling by invitationPhase 2
Testing remote arm conditioning to protect the brain in stroke
This Phase 2 study tests whether a simple remote method that briefly reduces blood flow in the arm (called ischemic conditioning) can help people with brain small-vessel disease or an acute ischemic stroke. Participants are monitored by phone and, for stroke patients, through a Mobile Stroke Unit.
Calgary, AlbertaAges 55 years+ - NCT06631378Recruiting
Groin incision direction study for vascular surgery patients
This trial compares two different ways of making an incision (cut) in the groin during blood vessel surgery. It aims to find out if one direction leads to better healing or fewer complications.
KoldingAges Any age - NCT07322913Recruiting
Study of Intervascular blood vessel grafts and patches
This study is collecting information from patients who have already had surgery to repair or replace blood vessels using Intervascular grafts or patches. Researchers will look at past medical records to see how well these devices work over time.
Hershey, PennsylvaniaAges 18 years+ - NCT06613555Recruiting
Eye blood vessel scan study for systemic disease
This study uses an advanced eye scan (OCT-A) to look at tiny blood vessels in the back of the eye. It compares people with systemic blood vessel conditions (like high blood pressure or inflammatory disease) to healthy volunteers, to see if the eye scan can help predict or understand these diseases.
DijonAges 18 years+ - NCT04360200Recruiting
Study of thinking changes in older adults
This trial looks at people over age 50 who have mild thinking or memory problems but do not have dementia by standard clinical criteria. It tests how these early changes are characterized and measured using exams such as blood tests and brain scans, which may help improve understanding and future care.
Guangzhou, GuangdongAges 50 years+ - NCT07386015Recruiting
Study of freezing of gait in Parkinson's disease
This study looks at people with Parkinson's disease or similar conditions who have walking problems like freezing of gait (feet feeling stuck) or balance issues. Researchers want to learn more about what causes these symptoms and how they affect people over time.
Tianjin, Tianjin MunicipalityAges 30–85 - NCT07396025Enrolling by invitation
Study of surgery for blocked carotid arteries
This trial looks at how well surgery and diagnostic tests work for people with a blocked carotid artery (the main artery in the neck that supplies blood to the brain). It may help if you have reduced blood flow to part of your brain and are able to understand instructions and communicate.
AstanaAges 18 years+ - NCT05704309Enrolling by invitation
Study of diabetes prevention participants using brain scans
This study looks at how people who previously took part in a diabetes prevention program are doing over time, including brain health using MRI scans for some participants. It may help researchers understand who is at higher risk for memory and thinking problems and why.
Phoenix, ArizonaAges Any age - NCT06733714Recruiting
Brain stimulation plus memory training for older adults
This study tests whether a gentle, non-invasive electrical current applied to the scalp (tACS) combined with computer-based brain exercises can improve memory and thinking in older adults who have concerns about their cognitive health.
Rio de Janeiro, Rio de JaneiroAges 50 years+ - NCT06325800Recruiting
Heart and blood vessel health registry
This study collects information from people at risk for heart disease, stroke, or kidney problems to better understand how to prevent these conditions. If you join, you'll be helping doctors learn more about how to keep blood vessels healthy.
Santiago de Compostela, A CoruñaAges 18 years+ - NCT07614386Recruiting
Radial artery access outcomes in heart and vessel procedures
This registry collects data from patients undergoing heart or blood vessel procedures using a small artery in the wrist (radial or ulnar artery) for access. Researchers track outcomes to better understand the safety and effectiveness of this approach.
Mersin, MezitliAges 18 years+ - NCT07771127Recruiting
Comparing a special pad to a sandbag for groin bleeding after heart procedure
This study compares two ways to stop bleeding after a heart procedure through the groin: using a special pad or a sandbag. It aims to see which method works better and is safer.
Bursa, NilüferAges 18 years+ - NCT05403151Recruiting
Healthy blood vessel and control study
This study looks at healthy adults and how their blood vessels work. It may help researchers understand normal circulation so they can better compare changes in future conditions.
Bethesda, MarylandAges 18–90 - NCT06419959Recruiting
NightWare watch for better sleep and heart health in veterans with PTSD
This study tests if a special watch (NightWare) can help veterans with PTSD who have nightmares sleep better and improve heart health. The watch vibrates gently during nightmares to reduce them without waking you up.
Aurora, ColoradoAges 22–88 - NCT06501742Recruiting
Major liver surgery and blood flow control study
This trial looks at how major liver surgery with controlled blood flow (vascular clamping) affects patients. It may help doctors improve outcomes for people who need this type of operation.
StrasbourgAges 18 years+ - NCT05628948Recruiting
Donate blood for a heart and metabolism research biobank
This study builds a “biobank,” which is a collection of blood and related samples, to support future research on heart and metabolic (sugar/body-fat) conditions. It may help researchers better understand these diseases and improve future prevention and treatments.
Cleveland, OhioAges 18 years+ - NCT07652632Recruiting
Regenerative endoscopy for hard-to-treat Crohn's fistulas
This trial tests a new, less invasive procedure called regenerative endoscopy to repair complex fistulas in people with Crohn's disease. It's for those who haven't gotten better with standard treatments like biologics or surgery.
Hyderabad, TelanganaAges 18–65 - NCT07359664Recruiting
Eye scans for heart health: a study of blood vessels
This study uses an eye scan called OCTA to look at blood vessels in the retina. It compares people with certain heart or blood vessel conditions (like high blood pressure or diabetes) to healthy volunteers to see if eye changes can help detect heart disease early.
Erlangen, BavariaAges 18–75 - NCT07510438Recruiting
Pulse IVL treatment for hardened arteries in the heart
This trial tests a new device that uses sound waves to break up calcium deposits in heart arteries, making them easier to open. It may help people with coronary artery disease who have not had prior stents or recent heart attacks.

Study breathing and blood changes after 9/11 exposure
This study looks at how breathing problems and blood vessel/heart issues may happen after World Trade Center (WTC) dust exposure. It uses blood samples and breathing tests to understand who may be affected and to compare people with and without WTC-related airway reactivity.
New York, New YorkAges 21–90 - NCT02966665RecruitingPhase 1
Testing blood vessel function in people of different health conditions
This early study measures how well your blood vessels work using tests that may include MRI. It compares healthy people with people who have conditions like COPD, pulmonary arterial hypertension, heart failure, or high blood pressure, to better understand “vascular function” in health and disease.

Common questions
- Are there clinical trials for vascular diseases?
- Yes. Clin2 currently lists 261 recruiting vascular diseases 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 diseases 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 diseases 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.
