Age-adjusted normal tolerance limits for cardiovascular autonomic function assessment in the elderly.

C V Clark, R Mapstone

    Age and Ageing

    PubMed
    Summary

    This study established normal autonomic nerve function test ranges for older adults. These findings aid in diagnosing conditions like diabetes and glaucoma in the elderly population.

    Area of Science:

    • Gerontology
    • Neuroscience
    • Cardiology

    Background:

    • Autonomic nervous system (ANS) dysfunction is common in the elderly.
    • Standardized autonomic function tests are crucial for assessing elderly health.
    • Specific age-adjusted reference values are needed for accurate interpretation in older populations.

    Purpose of the Study:

    • To establish age-adjusted normal tolerance intervals for standard autonomic function tests in a cohort of elderly subjects.
    • To discuss the clinical utility of autonomic function assessment in elderly patients, particularly those with diabetes mellitus, ocular hypertension, and primary glaucoma.

    Main Methods:

    • Autonomic nerve function was evaluated in 85 healthy elderly individuals (mean age 66.1 ± 10.2 years).
    • A series of standard cardiovascular reflex tests were employed.

    Related Experiment Videos

  • Age-adjusted normal tolerance intervals were determined for each test administered.

    • Main Results:

    • Normal tolerance intervals for autonomic function tests were established for the elderly cohort.
    • The study provides normative data specific to the aging population.

    Conclusions:

    • Established age-adjusted reference values enhance the diagnostic accuracy of autonomic function tests in the elderly.
    • Autonomic function assessment is clinically relevant for managing age-related conditions such as diabetes, ocular hypertension, and glaucoma.
