The 30-second chair stand test (CS30) as a predictor of exercise tolerance in elderly individuals (≥75 years) with stage A/B heart failure

Review written by Dr Mariana Wingood info

Key Points

  1. 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.

Among adults ≥65 years the leading cause of hospitalization is heart failure.

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
