Few studies have measured cognitive dysfunction in older adults during acute exacerbations of heart failure (HF), even though 25% of patients are readmitted within 30 days. The aims of this study were to examine cognitive dysfunction and acute HF symptoms in older adults hospitalized for HF and to evaluate the relationship between cognitive dysfunction and 30-day rehospitalization rates for acute HF. ⋯ Participants with more and worse symptoms had decreased speed and decreased accuracy in the cognitive domains tested. Cognitive dysfunction measures did not differentiate participants who were readmitted versus those who were not readmitted within 30 days for acute HF.
