Key result
Lower SPPB scores linked to ~28% higher risk of adverse outcomes in elderly HF patients.
Why the study?
Technical difficulty of the 6MWT often limits its utility in the elderly, and the prognostic role of the SPPB in AHF remains unclear.
Does the Short Physical Performance Battery (SPPB) provide comparable prognostic value to the 6-minute walking test (6MWT) for predicting death and readmission in hospitalized elderly patients with acute heart failure?
Population
1192 elderly patients hospitalized with AHF
Comparison
SPPB vs 6MWT
Design
Retrospective cohort study
Follow-up
1 year after discharge

SPPB identifies higher-risk elderly AHF patients; leaves open whether it adds value beyond 6MWT or alters management.
Does the Short Physical Performance Battery (SPPB) provide comparable prognostic value to the 6-minute walking test (6MWT) for predicting death and readmission in hospitalized elderly patients with acute heart failure?
Both SPPB and 6MWT predict 1-year mortality and HF readmission in elderly AHF patients, but 6MWT provides superior incremental prognostic value over conventional risk factors.
Kitai et al. (2021) studied this question. Lower SPPB scores (0–6) were associated with worse outcomes (HR 1.28) than higher scores (7–12) in elderly patients hospitalized for heart failure.
