Vascular Aging Index
Composite measure assessing arterial stiffness and vascular function changes related to aging in cardiovascular evaluation.
Full Definition
The Vascular Aging Index is a quantitative assessment tool that measures the degree of arterial stiffening and endothelial dysfunction associated with biological aging of the cardiovascular system. This index typically incorporates measurements such as pulse wave velocity, augmentation index, and arterial compliance to provide a comprehensive evaluation of vascular health. In geriatric cardiology, this measurement helps differentiate between normal age-related vascular changes and pathological processes, guides treatment decisions, and monitors therapeutic responses. The index is particularly valuable in risk stratification and determining appropriate blood pressure targets in elderly patients.
Usage
Usage note: Capitalize when referring to the specific standardized measurement; lowercase when used generically.
