Abstract

Introduction: The endurance shuttle walk test (ESWT) is a more responsive test of exercise capacity than the 6 minute walk test (6WT) in patients with chronic lung disease and could therefore provide a useful test of exercise capacity in older heart failure patients. We tested the performance of the endurance shuttle walk test in older patients with heart failure. 
Methods: Secondary analysis of data from a randomised controlled trial of exercise training for older heart failure patients. Baseline and 8 week follow-up data from intervention and control groups were used. Data were analysed using the SPSS-17 statistical package. Baseline distances walked in the two tests were compared using Pearson correlation coefficients. Intraclass Correlation Coefficient was calculated to assess reliability in those without significant change in six minute walk distance. Cohen’s effect sizes were calculated for participants with significant improvement or worsening of walk distance between baseline and 8 weeks. 
Results: Data from 107 patients were analysed. Mean age was 80 years; 72/107 were male. Mean baseline 6WT was 266m; mean baseline ESWT was 318m. There was a significant correlation between distance walked in 6WT and distance walked in ESWT (r= 0.67, p<0.001) and the intraclass correlation coefficient for the ESWT in stable patients was 0.78. 
Conclusion: The usefulness of the ESWT is limited by non-completion and ceiling effects.In older heart failure patients, the ESWT is no more responsive to change than the six minute walk.
