Cardiovascular Health of Older Adults and Resveratrol (CORE)

2016-09-21 20:23:22 | BioPortfolio


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.


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.

Medical and Biotech [MESH] Definitions

The process of aging due to changes in the structure and elasticity of the skin over time. It may be a part of physiological aging or it may be due to the effects of ultraviolet radiation, usually through exposure to sunlight.

The act of regarding attentively and studying facts and occurrences, gathering data through analyzing, measuring, and drawing conclusions, with the purpose of applying the observed information to theoretical assumptions. Observation as a scientific method in the acquisition of knowledge began in classical antiquity; in modern science and medicine its greatest application is facilitated by modern technology. Observation is one of the components of the research process.

Component of the NATIONAL INSTITUTES OF HEALTH. Through basic and clinical biomedical research and training, it conducts and supports research into the nature of the aging process and diseases associated with the later stages of life. The Institute was established in 1974.

The study of natural phenomena by observation, measurement, and experimentation.
