[Analysis of factors associated with anxiety in patients with atrial fibrillation and their caregivers].

Objective: To explore the risk factors of anxiety in patients with atrial fibrillation and their caregivers. Methods: From September 2020 to March 2021, patients with atrial fibrillation and one primary family member as caregiver of each patient from Beijing Anzhen Hospital were enrolled. Basic data of patients and their caregivers were collected, and anxiety of patients and caregivers were evaluated by Generalized Anxiety Disorder-7 scale (GAD-7). A total of 374 patients with atrial fibrillation and their caregivers were included in this study. Multivariate logistic regression analysis was used to analyze the risk factors of anxiety of patients and their caregivers. Results: The mean age of the patients was (58.3±10.6) years, and 124 (33.2%) were female. The caregivers were (53.6±11.6) years old, and 247 (66%) were female. 69 (18.4%) patients and 38 (10.2%) caregivers had mild anxiety (GAD-7:5-9 scores), 13 (3.5%) patients and 9 (2.4%) caregivers had moderate or higher anxiety (GAD-7:10-21 scores). Multivariate analysis showed that the risk factors of anxiety in patients with atrial fibrillation included EHRA score≥3 (OR=1.73,95%CI:1.03-2.89,P=0.039) and female sex (OR=1.90,95%CI:1.06-3.40,P=0.032). EHRA score of patients≥3 (OR=2.11,95%CI:1.05-4.24, P=0.036) or anxiety of patients (OR=2.76,95%CI:1.36-5.60,P=0.005) were associated with higher anxiety of caregivers. Moreover, age of≥65 years old (OR=3.97,95%CI:1.68-9.38,P=0.002), female sex (OR=3.83,95%CI:1.64-8.93,P=0.002) and number of comorbidities of caregivers≥2 (OR=2.57,95%CI:1.03-6.41,P=0.043) were also associated with anxiety of caregivers. Conclusions: Patients with severe symptoms have a higher proportion of anxiety, and their caregivers are more likely to experience anxiety. Anxiety rate is higher in caregivers of patients with anxiety.
