Improving heart blood flow after a first heart attack
This study tests a way to improve blood flow in the small vessels of the heart after a first heart attack. It is for people who have a specific type of heart attack in the front part of the heart and are treated quickly with a catheter procedure.
Harbin, HeilongjiangAges 18 years+ - NCT06669962Recruiting
Studying heart function in Takotsubo syndrome
This trial aims to understand the chemical and physical changes in the heart's blood vessels during Takotsubo syndrome, a temporary heart condition often triggered by stress. It may help doctors better diagnose and treat this condition.
Turin, TurinAges 18–90 - NCT06669520Recruiting
Renalase and blood vessel blockages after heart attack
This study is looking at a protein in the blood (renalase) and how it relates to blockages in tiny blood vessels after a heart attack. Researchers want to see if this protein can help predict recovery, which could lead to better treatments.
Changsha, HunanAges 18 years+ - NCT05682924Recruiting
Study blood vessel function in CML patients on bosutinib
This study looks at how well your blood vessels work (“vasoregulation”) in people with chronic myeloid leukemia (CML) while taking bosutinib. The goal is to understand vascular changes and how they relate to treatment in CML.
MoscowAges 40–60 - NCT07566598Recruiting
Brain Blood Flow Measurement After Stroke Treatment
This study measures how well blood flows through the brain after a special procedure to remove a blood clot causing stroke. Researchers use a tiny temperature sensor to understand blood circulation, which may help improve stroke care.
Nice, Alpes-maritimesAges 18–80 - NCT07499401Recruiting
Fluid response test in ICU patients with vein congestion
This study looks at how tiny blood vessels respond to extra fluids in ICU patients who have vein congestion. It helps doctors understand if giving more fluid is helpful or harmful for you.
Ancona, ItalyAges 18 years+ - NCT06749756Recruiting
Vitamins B6, B12 and C for sepsis
This trial tests whether a combination of vitamins B6, B12, and C can help improve blood flow in tiny blood vessels (microcirculation) for people with sepsis. It may help your body recover better from severe infection.
Chengdu, SichuanAges 18–85 - NCT06341062Recruiting
Ultrasound test for kidney injury in the ICU
This study tests whether a special ultrasound with a contrast dye can help doctors better assess acute kidney injury (a sudden drop in kidney function) in patients in the intensive care unit. If you or your loved one has been diagnosed with acute kidney injury within 24 hours of ICU admission, this imaging test may help guide care.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06799832Recruiting
Guiding fluid management during major abdominal surgery using a new index
This study tests whether a new tool, the urethral perfusion index, can help doctors better manage fluids during and after major abdominal surgery. It uses standard catheters already in place, so there's no extra device needed.
HamburgAges 45 years+ - NCT07338695Enrolling by invitation
Light therapy’s effect on blood flow in healthy adults
This study tests if shining a specific type of light on your skin can improve blood flow in tiny blood vessels. You'll come in for two sessions where we apply different light wavelengths and measure your skin’s response.

Common questions
- Are there clinical trials for microcirculation?
- Yes. Clin2 currently lists 32 recruiting microcirculation 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 microcirculation 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 microcirculation 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.
