Assessment of Frailty and Occurrence of Anxiety and Depression in Elderly Patients with Atrial Fibrillation

PURPOSE: Atrial fibrillation (AF) is the most common cardiac arrhythmia, and its incidence increases with age. The elderly population is commonly affected by frailty syndrome (FS). FS syndrome along with anxiety and depressive symptoms are prevalent among elderly patients with AF. It is unclear whether depression contributes to AF or vice versa. The purpose of this study was to assess correlations between FS and the occurrence of anxiety and depression symptoms in a group of elderly patients with AF. PATIENTS AND METHODS: This cross-sectional study included 100 elderly patients (69 females, 31 males, mean age: 70.27 years) with AF. Standardized research instruments were used including the Tilburg Frailty Indicator (TFI) to assess FS, and two questionnaires to assess depression including the Geriatric Depression Scale (GDS), and the Hospital Anxiety Depression Scale (HADS). RESULTS: Mild FS was found in 38% and moderate FS in 29% of patients. Based on GDS scores, depression symptoms were found in 51% of patients' sample. Based on HADS scores, 20% of patients were found to have anxiety symptoms, and 28% revealed depression symptoms. Single-factor analysis demonstrated a significant positive correlation between HADS anxiety symptoms (r=0.492), HADS depression symptoms (r=0.696), and GDS score (r=0.673) on the one hand, and overall TFI frailty score on the other. Multiple-factor analysis identified overall GDS score, education, and lack of bleeding as significant independent predictors of TFI scores (p<0.05). CONCLUSION: FS is common in the population of elderly patients with AF. We found evidence for the association between symptoms of anxiety and depression and the incidence of FS in this group of patients. Due to the risk of consequences which may in part be irreversible, screening for FS is recommended.
