Standardized gait speed ratio in elderly patients with heart failure.

ABSTRACT:

Aims

Although aging is strongly associated with both heart failure and a decline in gait speed, a definition of slowness incorporating an age-related decline has yet to be developed. We aimed to define an event-driven cut-off for the relative decline in gait speed against age-adjusted reference values derived from the general population and evaluate its prognostic implications.

Methods and results

Standardized gait speed (SGS) was defined as the median gait speed stratified by age, sex, and height in 3777 elderly (age ≥ 65 years) individuals without a history of cardiovascular diseases (Tokyo Metropolitan Institute of Gerontology-Longitudinal Interdisciplinary Study on Aging: general population cohort). The mortality event-driven optimal cut-off of the SGS ratio (actual gait
