Endothelial Dysfunction clinical trials at UCLA

2 research studies open to eligible people

Showing trials for
  • Key Dimensions of PTSD and ED

    open to eligible people ages 18 years and up

    This study will test whether endothelial dysfunction could be the early subclinical mechanism by which posttraumatic stress disorder (PTSD) increases cardiovascular disease (CVD) risk, and whether posttraumatic fear-a key component of PTSD-or another PTSD dimension could be the target to offset that risk. The results of this study may help trauma-exposed individuals who are at risk of having CVD events.

  • COMP-4 Supplementation and Brachial Artery FMD

    open to eligible people ages 18-39

    In a young and healthy person, the production of nitric oxide (NO) by the endothelium, the inner lining of the blood vessel, is responsible for a) the ability of the blood vessel to dilate so it can increase its blood flow and b) act as an anti-clotting product to prevent blood clotting in those vessels. Under physiological stress either due to the development of a disease such as diabetes or simply from aging, the endothelial cells can be impacted and become dysfunctional thereby impairing their ability to make NO and even promote the development of blood clots. When such endothelial dysfunction occurs, it may be a precursor for the future development of cardiovascular (CV) disease like hypertension or even coronary artery disease later on in life in these patients. Therefore, the ability to somehow enhance the local production or availability of NO within such affected blood vessels in patients identified as prone to endothelial dysfunction could play a positive role in either preventing or delaying the onset of endothelial dysfunction and subsequent CV disease in such patients. COMP-4 is a safe, clinically available, well tolerated oral supplement that has been shown in the lab to increase NO production in a number of differing tissues including human vascular endothelial cells. In this proposed human study, the investigators plan on recruiting healthy, young participants willing to take COMP-4 for a 14 day period in whom the investigators will measure in a non-invasive way - by the use of ultrasound - the effect of COMP-4 on its ability to improve blood flow in one of the major blood vessels of the upper arm. In addition, the investigators will also determine whether COMP-4 will be capable of lowering in the blood the levels of two of the most studied inflammatory markers associated with endothelial dysfunction, IL-8 and PAI-1.
