To explore the influencing factors of anxiety and depression in patients with coronary heart disease after percutaneous coronary intervention (PCI), so as to provide theoretical basis for psychological intervention.

This study was a cross-sectional study. From November 2021 to March 2022, 150 patients with coronary heart disease after PCI were selected from the Department of Cardiovascular, Zhongnan Hospital of Wuhan University by convenience sampling. The patients were investigated with the General Information Questionnaire, Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and Social Support Rating Scale (SSRS). Pearson correlation was used to explore the relationship among anxiety, depression and social support in patients with coronary heart disease after PCI.

Among 150 patients with coronary heart disease after PCI, the total score of social support was 31.0 (28.0, 36.0), including 33 cases of anxiety (33/150, 22.0%), 47 cases of depression (47/150, 31.3%), and 27 cases of anxiety and depression (27/150, 18%). Pearson correlation analysis showed that the total score and each dimension score of SSRS of patients with coronary heart disease after PCI were negatively correlated with SAS and SDS scores (P<0.05) .

Patients with coronary heart disease after PCI are prone to anxiety and depression. While paying attention to patients' physical diseases, medical and nursing staff should pay attention to patients' psychological conditions, find negative emotions as early as possible and give targeted intervention and treatment.
