Association between heart failure severity and mobility in geriatric patients: an in-clinic study with wearable sensors.

Background: Individuals with heart failure (HF) frequently experience limitations in mobility, but specific aspects of these limitations are not well understood. This study investigated the association of HF severity, based on the New York Heart Association (NYHA) classes, with digital mobility outcomes (DMOs) and handgrip strength in older inpatients with HF.

Methods: For this explorative analysis, hospital admission and discharge data from an ongoing, prospective cohort study were used.
