Key result
Glittre ADL-Test time inversely correlates with peak VO2 in patients with HF.
Why the study?
Submaximal tests like the Glittre ADL-Test may better correlate with daily living limitations in heart failure, prompting investigation into its correlation with peak VO2.

Effect estimate: r = -0.424

The Glittre ADL-Test is a reproducible submaximal test that correlates significantly with peak VO2, offering a practical tool for evaluating functional capacity in heart failure patients.
Supports Glittre ADL-Test as peak VO2 surrogate in heart failure; hypothesis-generating and requires prospective validation before practice change.
Background: The Weber classification based on peak VO2 is a well-established method for categorizing patients with heart failure (HF) regarding severity. However, other submaximal tests such as the Glittre ADL-Test have been gaining prominence in practice due to a coherent and more comprehensive correlation with limitations for performing activities of daily living in patients with heart failure.Objective: To investigate the correlation between the time required to perform the Glittre ADL-Test and the peak VO2 in patients with HF.Methods: A cross-sectional study conducted with 40 adult individuals (21 to 65 years) diagnosed with HF of all etiologies, with LVEF<50% and NYHA II and III.Results: The average time for performing the Glittre ADL-Test was 284.9 seconds, and a significant difference was found between Weber classification classes A and C (p = .01). Significant correlations with peak VO2 were also found (r = −0.424 – p < .01). Thirty (30) patients performed a second test, and the ICC found in the reproducibility analysis was 0.75 (95% CI 0.14–0.91) and p < .01.Conclusion: The Glittre ADL-Test was able to reflect the functional performance of individuals with HF, suggesting that it represents an evaluation tool which can be safely used in clinical practice.

Leite et al. (2020) conducted a cross-sectional in heart failure (n=40). Glittre ADL-Test was evaluated on correlation between the time required to perform the Glittre ADL-Test and the peak VO2 (r = -0.424, p=<0.01). The time required to perform the Glittre ADL-Test showed a significant negative correlation with peak VO2 in patients with heart failure (r = -0.424, p < 0.01).
