ENDOTHELIAL DYSFUNCTION

This study is testing whether eating wild blueberries daily can help lower blood pressure and improve artery function in middle-aged and older adults with mildly elevated blood pressure. Researchers are enrolling 58 men and postmenopausal women aged 45-70 to measure changes in bl…

This study is testing if a medication called dulaglutide can improve the health of tiny blood vessels in the muscles of adults with type 1 diabetes. Researchers believe better blood flow might help the body use insulin more effectively. The trial is currently suspended and was co…

This was an add-on study to a larger trial testing if breathing nitric oxide gas during and after heart surgery helps protect patients' blood vessels. It focused on patients with existing blood vessel problems who were having long surgeries using a heart-lung machine. The goal wa…

This study is testing if a natural compound called fisetin, found in fruits and vegetables, can improve blood vessel function and reduce artery stiffness in adults aged 65 and older. Researchers want to see if short-term, intermittent treatment is safe and if it works by reducing…

This was an add-on study to a larger trial testing nitric oxide gas in heart surgery patients. It aimed to understand the biological mechanisms—specifically how nitric oxide affects oxidative stress levels in the blood—that might explain why the gas could help reduce post-surgery…

This study aims to better understand why some people experience chest pain and signs of reduced blood flow to the heart, even though their main heart arteries look clear on standard tests. Researchers will observe 500 patients with this condition, using advanced tools during a he…

This study aimed to learn if a simple blood test could detect and predict blockages in the small blood vessels of the heart in people who have had a heart transplant. Researchers planned to check blood levels of donor DNA every few months and compare them to heart scan results ov…
