Influencing factors of care dependence in patients with coronary heart disease after percutaneous coronary intervention—A cross‐sectional study

AIM: Care dependence has been scarcely investigated in coronary heart disease patients after percutaneous coronary intervention. This study aimed to investigate the association between frailty, self‐efficacy, combined effects of frailty and self‐efficacy, mental health, and care dependence in coronary heart disease patients after percutaneous coronary intervention. DESIGN: Cross‐sectional study. METHODS: Data from 400 patients after percutaneous coronary intervention were collected from 2017–2020. Logistic regression model and mediating analysis were used to identify the association between frailty, self‐efficacy, combined effects of frailty and self‐efficacy, and care dependence. RESULTS: Patients with frailty and self‐efficacy tended to have severe care dependence symptoms. There was no correlation between frailty symptoms, self‐efficacy, and care dependence in patients without symptoms of anxiety or depression. But in patients with anxiety or depression symptoms, there is a strong correlation between frailty symptoms, lower self‐efficacy, and care dependence. Mental health played an inhibitory effect on frailty and care dependence.
