Abstract 13431: Cognitive Dysfunction in Elders Hospitalized for Acute Heart Failure
Background/Significance: Understanding acute heart failure (HF) symptoms (dyspnea, fatigue, pain) and their relationship to cognitive dysfunction (CD) is important because they may lead to poor learning and self-care performance, adding to the burden of illness during the acute phase and persisting as an added disability in the long-term.
Purpose: To examine the relationship between acute HF symptoms and CD (reaction time, attention/vigilance and memory).
Methods: Using a predictive correlational design, 53 adults were recruited from a Midwestern university affiliated hospital. CogState computerized neuropsychological tests were used to measure specific cognitive domains. Established questionnaires were used to measure HF symptoms (Parshall Brief Clinical Dyspnea Rating Questionnaire; Brief Fatigue Scale, McGill Pain Questionnaire) and depressed mood (Hospital Anxiety and Depression Scale (depression scale only). To standardize data collection and minimize missing data, all questionnaires were loaded on a computer and read to participants.
Results: Participants were largely male (66%), White (93%), and a mean age of 72 years (SD =5.3 years). Using multiple linear regression, acute HF symptoms in isolation and in combination with other symptoms were predictive of CD (reaction time, visual attention/vigilance and attention and memory-see Table).
Conclusions: More and worse HF symptoms were associated with decreased speed and accuracy. Delays were noted in reaction times, visual attention/vigilance and attention and working memory. Interventions are needed to improve/enhance cognitive function (specifically attention and memory) for elders hospitalized with acute HF.
