Brief Summary:
Researchers have found a link between chronic obstructive pulmonary disease (COPD) and heart disease; however, a link is all they have found. Cardiovascular health in COPD is controlled by different mechanisms including vascular health and systemic inflammation. The investigators have collected preliminary data to support that concentrations of Sirtuin 1 (Sirt1), a protein that plays a key role in cardioprotection, may be involved in cardiovascular health in patients with COPD. Resveratrol, an over the counter natural polyphenol found in a variety of food, is a direct activator of Sirt1 and has been used to improve cardiovascular health in different cohorts. The current project is an attempt to expand previous findings and explore the effects of the sub-chronic use of resveratrol in sustaining the improvements in cardiovascular health in COPD.

Condition or disease Intervention/treatment Phase
Chronic Obstructive Pulmonary Disease Dietary Supplement: Resveratrol Other: Placebo Not Applicable

Detailed Description:
The present study is designed as a double-blind, randomized, cross-over, placebo-controlled protocol. Patients with COPD will receive either resveratrol (500 mg) or placebo for 12 weeks. A comprehensive evaluation of cardiovascular health will be performed. Results will provide novel insights into the mechanistic role that Sirt1 mediates in COPD related vascular dysfunction and systemic inflammation.

Primary Outcome Measures :
  1. Change in Sirt1 concentrations [ Time Frame: Baseline to 12 weeks ]
    Circulating concentrations of Sirt1 before and 12 weeks after both resveratrol and placebo

  2. Change in vascular health [ Time Frame: Baseline to 12 weeks ]
    Assessment of vascular health through the evaluation of peripheral vascular using the flow-mediated dilation technique before and 12 weeks after both resveratrol and placebo.

  3. Change in Systemic Inflammation [ Time Frame: Baseline to 12 weeks ]
    Systemic inflammation will be evaluated through the assessment of interleukin concentrations using enzyme-linked immunosorbent assay before and 12 weeks after both resveratrol and placebo.


Secondary Outcome Measures :
  1. Change in Nitric Oxide metabolism [ Time Frame: Baseline to 12 weeks ]
    Nitric oxide metabolism will be evaluated through Nitric oxide synthase expression using western blot analysis

  2. Change in Inflammatory activation [ Time Frame: Baseline to 12 weeks ]
    The inflammatory cascade of the nuclear factor kappa B will be evaluated through assessment of p65 and p50 expression using western blot analysis
