Brief summary
Cardiovascular health is a critical problem in patients with chronic obstructive pulmonary disease (COPD). Existing literature suggests oxidative stress from the mitochondria c driving some of the poor health outcomes in COPD. MitoQ is a mitochondrial-targeted antioxidant that has shown promise in improving cardiovascular outcomes in similar populations. Thus the purpose of this study is to test if MitoQ can improve cardiovascular health in COPD.
Detailed description
In this study, a mitochondria-specific antioxidant will be compared to a placebo. Participants will be assigned randomly to receive either the antioxidant or the placebo for 6 weeks. A comprehensive assessment of cardiovascular health will be conducted before and after the administration of the supplement.
Interventions
MitoQ is a mitochondrial targeted antioxidant that can be obtained over-the-counter.
A look-alike inactive substance, a sugar pill
