Role of Mitochondrial-derived Oxidative Stress to Promote Vascular Endothelial Dysfunction in Non-exercisers With Aging

Completed · Not applicable · Has a placebo group

Conditions studied: Aging, Endothelial Dysfunction, Cardiovascular Function, Arterial Stiffness

In brief

The primary goal of this intervention is to determine the efficacy of acute mitochondrial-specific antioxidants to improve vascular endothelial function in middle-aged and older (≥45 y) adults who do no perform regular aerobic exercise. In a double-blind, randomized, placebo-controlled crossover design participants with receive both MitoQ and placebo arm of the study. Primary endpoints will include vascular endothelial function assessed by brachial artery flow-mediated dilation and cardiac function assessed via pulse wave analysis. Secondary endpoints will include measures of aortic stiffness assessed by carotid-femoral pulse wave velocity and carotid artery stiffness (e.g. β-stiffness) and elasticity (carotid compliance, distensibility, and Youngs elastic modulus) from ultrasonography.
