Vascular Aging: The Link That Bridges Age to Atherosclerosis (The VALIDATE Study)

Brief Summary

Detailed Description

The prevalence, incidence, and severity of atherosclerotic disease all markedly increase with age. Basic experimental and observational data demonstrate that aging magnifies the pathologic and clinical consequences of established risk factors and is the most potent individual risk factor for coronary atherosclerosis and for adverse outcomes following an ischemic event. These findings suggest that normal aging alters the vascular substrate so as to promote the development and progression of atherosclerosis. The age-associated changes in vascular structure and function include an increase in central vascular stiffness, intimal proliferation, and endothelial dysfunction. The major hypothesis is that the above alterations in vascular substrate (i.e. vascular age) are an important determinant of the age associated increased likelihood for the development and progression of coronary atherosclerotic disease. This protocol will non-invasively characterize vascular age and atherosclerotic burden in BLSA participants and individuals with successful aging, i.e. those with no or minimal evidence of coronary atherosclerotic disease, and those with premature, clinically evident coronary artery disease. It will repeat measures of vascular age and atherosclerotic burden three years after the first assessment. By examining the impact of vascular age on the initial extent and the progression of atherosclerotic burden over a two to three-year period, it will test the hypothesis that vascular age is an important determinant of the age-associated increase in atherosclerotic disease.
