The 30-second chair stand test (CS30) as a predictor of exercise tolerance in elderly individuals (≥75 years) with stage A/B heart failure
Key Points
- Older adults with heart failure have reduced peak VO2 and exercise tolerance, resulting in increased risk of frailty and functional decline.
BACKGROUND & OBJECTIVE
Among adults ≥65 years the leading cause of hospitalization is heart failure (HF) (1). Heart failure is also associated with reduced quality of life, risk for institutionalization, and long-term mortality (1). An essential measure among individuals with HF, is peak oxygen uptake (peak VO₂), with the gold standard being cardiopulmonary exercise testing (2). However, cardiopulmonary exercise testing requires expensive equipment and is not feasible in a clinical setting (2). Thus, alternative tests such as the 30 second sit-to-stand (STS), also known as the chair stand test, are needed.
The aim of this study was to examine if the 30 sec STS test is a predictor of exercise tolerance among older adults with stage A/B HF.
Clinicians can use the 30 sec sit to stand cut-offs identified in this study to determine a greater need for cardiac rehabilitation or one-on-one physical therapy.
METHODS
Participants: 493 outpatients aged ≥ 75 years; exclusion criteria included:1) previous hospitalization owing to HF; 2) history of valvular disease; 3) palpitations as the sole symptom; 4) presence of a cardiac pacemaker 5) certification for long-term care insurance, including patients
