Why the study?
Is gait speed associated with dependent functional status in older adults with severe aortic stenosis?
Is gait speed associated with dependent functional status in older adults with severe aortic stenosis?
Gait speed is a useful, objectively measurable risk stratification tool that strongly associates with dependent functional status in older adults with severe aortic stenosis.
Gait speed may identify functional dependence in older adults with severe aortic stenosis; leaves open its added value over standard risk tools.
Although the prevalence of slow GS in a population of elderly patients with severe AS being screened for transcatheter valve was high, there were only weak associations between GS and other risk stratifying tools. The strong association between GS and dependent functional status suggests that assessment of gait speed is a useful, objectively measurable, risk stratification tool in this population.
