BACKGROUND: Patients with cardiovascular disease (CVD) often experience anxiety and depression. However, the central and bridge symptoms of anxiety and depression among patients with CVD remain unclear. Network analysis is a statistical method that can reveal and visualise complex relationships between multiple variables. This study aimed to identify the central and bridge symptoms in the anxiety-depression network, which may provide potential targets for preventing and intervening in anxiety and depression. METHODS: A total of 1180 patients with CVD were selected from the Psychology and Behavior Investigation of Chinese Residents. The survey was conducted from July 10 to September 15, 2021. Face-to-face electronic questionnaires were distributed to respondents by the investigators. The Generalized Anxiety Disorder 7 (GAD-7) and Patient Health Questionnaire-9 were used to assess anxiety and depressive symptoms among patients with CVD. Network analysis was conducted using R4.02 to identify central and bridge symptoms in the anxiety-depression network. RESULTS: Among the 1180 patients with CVD included in this study, 673 (57%) were male and 507 (43%) were female. More than half (53.5%) of patients were under 60 years old. The mean GAD-7 score was 4.66 ± 4.38, and 169 (14.3%) patients had anxiety symptoms. The mean PHQ-9 score was 6.29 ± 5.29, and 235 (19.9%) had depressive symptoms. Furthermore, 144 (12.2%) patients people had both anxiety and depressive symptoms. In the networ...
