Aging Clinical Trial - Cardiovascular Health of Older Adults & Resveratrol

Status Completed

Clinical Trial Summary

This study will investigate how resveratrol (phenol present in red grapes, wine and peanuts) can improve heart muscle function and ability of arteries to dilate in response to an increase in blood flow in adults 65 years of age and older. Additionally, investigators will look at how resveratrol can improve functioning of cells (cellular house-keeping) which can be related to cardiovascular function.

Clinical Trial Description

Age-related declines in left ventricular function and endothelium-dependent vasodilation increase the risk for cardiovascular (CV) disease and premature death in older adults. Structural changes to the arterial wall and cardiac muscle are indicated as a cause and appear to be induced by age-related oxidative stress and inflammation and reduced levels of autophagy, the cellular "house-keeping system". Pre-clinical studies indicate that resveratrol (RSV), a polyphenol present mostly in grapes and red wine, may improve left ventricular cardiac muscle and endothelial vasodilator function. Although, RSV has been shown to induce autophagy and improve CV function in animals, evidence for its effects on the CV system in humans is lacking, and there is a need for clinical trials to better understand the effects of RSV on CV function in humans. Because older adults are most likely to have impairments in the central and peripheral CV systems, they represent an ideal population to test the effects of RSV on CV function. Therefore, the central hypothesis is that RSV supplementation will improve age-related left ventricular cardiac muscle function and arterial vasodilation in older adults (> 65 years). The participants will undergo 90 days of RSV treatment (n=12) (1,000mg/day), or (n=12) (1,500mg/day) or placebo (n=12). Before and after the intervention, investigators will non-invasively investigate left ventricular and arterial vasodilator function. Additionally, investigators will examine cardiac muscle damage and inflammatory biomarkers in blood and autophagy and endothelial function protein levels and in skeletal muscle to better understand molecular mechanisms that may underlie the hypothesized beneficial effects of RSV on cardiovascular health in older adults. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
