ABSTRACT
Abstract Background Cognitive impairment, anxiety, and depression are present in patients with heart failure (HF), but their mutual correlation in hospitalized patients is not well established. Objectives The aims of this study were to identify the presence of cognitive impairment and the most affected domain, to investigate possible associations of cognitive impairment with depression and/or anxiety, and to observe whether they correlated with occurrence of readmission within 30 days following hospital discharge. Methods This is a prospective observational study including patients with HF from a private hospital. Psychological distress and cognition were evaluated by the Hospital Anxiety and Depression Scale (HADS) and by the Mini Mental State Exam (MMSE), respectively. Clinical data were obtained from the medical record at the time of inclusion, and outpatient follow-up was performed 30 days after discharge via telephone calls. Results This study included 71 patients (83% men, 75 ± 11 years). Cognitive impairment was present in 53.5% of the patients, and recall memory was the most altered cognitive domain. The proportion of possible/probable anxiety and depression was 21.1% and 34.2% in patients with cognitive impairment, respectively. However, only depression demonstrated association with cognitive impairment (p = 0.018). Cognitive impairment, anxiety, and depression showed no relationship with the occurrence of readmission within 30 days. Conclusions Cognitive impairment and depressive symptoms are prevalent and associated, and recall memory was the most altered cognitive domain in patients hospitalized with HF. However, there was no relationship between these factors and readmission within 30 days.
