Effects of cumulative cognitive function within 1-year of discharge on subsequent mortality among patients hospitalized for acute heart failure: A nationwide prospective cohort study.

Poor cumulative cognitive function was associated with increased risk of subsequent mortality and provided incremental prognostic ability for the outcomes among patients with AHF. Longitudinal assessment and monitoring of cognitive function among patients with AHF would be of great importance in identifying patients at greater risk of self-care absence for optimizing personal disease management in clinical practice.
