Official title
Regulation of Nitric Oxide Bioavailability in Chronic Obstructive Pulmonary Disease: A Mechanistic Approach
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
More patients with chronic obstructive pulmonary disease (COPD) die from cardiovascular disease than direct pulmonary complications. Inflammation and oxidative stress, characteristic in COPD, are likely contributors to the reduction in nitric oxide (NO) bioavailability and vascular endothelial dysfunction in COPD patients; however, this has yet to be determined. Thus, the overall objective of this proposal is to identify the role of NO bioavailability in contributing to vascular endothelial dysfunction in patients with COPD and to provide insight into the molecular mechanisms involved. Our central hypothesis is that inflammation and oxidative stress, both independently, contribute to the reduction in NO bioavailability and vascular endothelial dysfunction in patients with COPD.
