Blood vessel particles in children with new high blood pressure
This study looks at tiny particles in the blood (called extracellular vesicles) that may signal early blood vessel changes in children with new high blood pressure. If your child is between 6 and 17, has just been diagnosed with high blood pressure and hasn't started treatment, and is otherwise healthy, this trial may help doctors better understand how high blood pressure affects kids.
OsijekAges 6–17 - NCT05000515Recruiting
Breathing muscle training to lower blood pressure in postmenopause
This study compares a breathing-based exercise program with regular aerobic exercise to help lower blood pressure and improve blood vessel function in postmenopausal women. It’s mainly for people with mildly elevated resting blood pressure who are not already doing very intense workouts.
Boulder, ColoradoAges 50 years+ - NCT03253705Recruiting
Donate small blood samples to study heart and inflammation health
This study collects small blood samples (and sometimes samples during treatment) to help researchers understand diseases involving the heart, inflammation, and blood vessel function. It may help improve future tests and treatments by giving scientists usable human data.
Bethesda, MarylandAges 18–100 - NCT03822949Recruiting
Bright light exposure during heart surgery for better recovery
This trial tests whether using bright light at the right time during and after heart surgery helps patients recover more comfortably. It focuses on people having a specific type of open-heart surgery and checks certain heart rhythm and safety factors.
Denver, ColoradoAges 18–90 - NCT04482374Recruiting
Puberty blockers and heart/metabolic health in teens
This study looks at how puberty suppression (puberty blockers) may affect heart health and metabolism in children who are early in puberty. It may help researchers understand who benefits most and what changes happen during treatment.
Aurora, ColoradoAges 9–14 - NCT04646252Recruiting
Testing a blood-surface feature to prevent heart problems
This study looks at whether a healthy blood lining (the glycocalyx) can help predict and reduce the risk of major heart events in people who have not yet had heart disease. You may be asked to do screening tests and share health information to see how these factors relate to future risk.
Athens, AtticaAges 18–85 - NCT05065372RecruitingPhase 1
Metformin test with automated insulin in teens with type 1
This Phase 1 study tests how adding metformin affects blood flow in the kidneys, insulin sensitivity, and overall heart/metabolic health in young people with type 1 diabetes. It may help researchers understand whether this combo is safe and beneficial alongside automated or pump/shot insulin care.
Aurora, ColoradoAges 12–25 - NCT05199454Recruiting
Study how “fat-like” particles affect blood vessel function
This study looks at whether tiny fat-based particles (“adiposomes”) can affect how well your blood vessels work, especially in people with diabetes and higher body weight. You may be asked to do moderate exercise and other study procedures after passing safety checks.
Chicago, IllinoisAges 18–50 - NCT05289063RecruitingPhase 1
Study new sleep apnea and blood vessel function
This Phase 1 study looks at how blood vessel function is affected by obstructive sleep apnea in adults who are newly diagnosed and have not used CPAP. It may help researchers understand the early effects of sleep apnea and guide future treatments.
New York, New YorkAges 18 years+ - NCT05344573Recruiting
Testing better blood-flow rhythms during heart bypass surgery
This trial studies ways to control the “pulsatility” (how the blood pressure pulses during circulation) while you are on a heart-lung bypass machine. It may help improve safety and heart function during planned heart surgery.
Aurora, ColoradoAges 50–70 - NCT05366933RecruitingPhase 1
B-Complex vitamins to protect astronauts during long space missions
This early study tests whether a B-vitamin supplement (called B-Complex) can act as a helpful countermeasure during long stays on the International Space Station. It is only for astronauts assigned to specific 6–12 month missions.
Houston, TexasAges 20–100 - NCT05553223Recruiting
Very small activity doses for COPD symptoms
This study tests whether “micro-doses” of physical activity (short, small amounts) can help people with COPD. It aims to see if these small activity bursts are safe and beneficial for people who have stable COPD.
Kelowna, British ColumbiaAges Any age - NCT05778981Recruiting
Study of blood-vessel health during non-heart surgery
This study looks at how blood-vessel function changes around the time of non-heart surgery, especially in people 45 and older. It may help doctors better understand risks and recovery related to blood-vessel stress during hospitalization.
Independencia, Santiago MetropolitanAges 45 years+ - NCT05808686RecruitingPhase 2
Exercise-based training for circulation in older, frail adults
This study tests a special exercise training approach to help small blood vessels work better and improve resilience in frail older adults. If you join, you’ll do training that may involve temporary blood-flow restriction, so safety rules are important.
Wauwatosa, WisconsinAges 65–85 - NCT05812755RecruitingPhase 4
Study drug effects on blood vessels and organs in heart surgery
This Phase 4 trial studies vericiguat-like stimulation (a type of medicine that affects blood-vessel signaling) around the time of planned open-heart surgery. It aims to see whether this can change blood-vessel “reactivity” and reduce injury to organs during and after surgery.
Nashville, TennesseeAges 18 years+ - NCT05939934Recruiting
Test a mouth device for sleep apnea after stopping CPAP
This study looks at whether a mandibular advancement device (a fitted mouthpiece) can control sleep apnea when you temporarily stop CPAP. It’s mainly for people who have been using CPAP for over a year but are now willing to try the mouth device.
AngersAges 18–75 - NCT06308952RecruitingPhase 4
Atorvastatin before flow diverter for brain aneurysms
This trial tests whether taking atorvastatin before a flow diverter procedure can prevent strokes or other brain events in people with unruptured brain aneurysms. It may help reduce complications from the treatment.
Guangzhou, GuangdongAges 18–75 - NCT06319274RecruitingPhase 2
Prostacyclin for lung infection patients on a ventilator
This study tests a medicine called prostacyclin (given through a vein) to see if it helps people on a breathing machine with a lung infection. The goal is to reduce inflammation and improve recovery.
CopenhagenAges 18 years+ - NCT06454344Recruiting
Sleep and childhood experiences study in young adults
This study looks at how sleep is affected by tough childhood experiences. It tests whether changing sleep patterns can help young adults who have had these experiences and currently have poor sleep.

Common questions
- Are there clinical trials for endothelial dysfunction?
- Yes. Clin2 currently lists 55 recruiting endothelial dysfunction 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 endothelial dysfunction 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 endothelial dysfunction 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.
