Objective: We aimed to assess the effects of nursing intervention therapy based on chronic disease trajectory model on anxiety and quality of life (QOL) of patients with coronary heart disease (CHD). Methods: A total of 118 CHD patients admitted from February 2019 to February 2021 were randomly assigned into control and observation groups (n=59). Control group was given routine nursing intervention, while observation group was given intervention based on chronic disease trajectory model. Clinical symptom, self-rating anxiety scale (SAS), QOL and self-efficacy scores were compared. Incidence rates of complications were compared. Multivariate linear regression analysis was performed for the mediating effect of self-efficacy on relationship between anxiety and QOL. A structural equation model was constructed and verified. Results: After intervention, clinical symptom and SAS scores significantly declined in both groups, especially in observation group (P<0.05). QOL and selfefficacy scores rose significantly in both groups, particularly in observation group (P<0.05). Self-efficacy score was negatively correlated with SAS score and positively correlated with QOL score, and there was a negative correlation between SAS score and QOL score (P<0.05). The model of self-efficacy, anxiety and QOL had good fitness, and the mediating effect of self-efficacy on relationship between anxiety and QOL was 0.896. The incidence rate of complications was significantly lower in observation group than in control group (P<0.05). Conclusion: Nursing intervention based on chronic disease trajectory model significantly relieves the anxiety, improves QOL, and increases the self-efficacy score of CHD patients. Self-efficacy is a mediator for the relationship between anxiety and QOL.
