Objective: To explore the effect of the Green model on the lifestyle changes of young and middle-aged patients with coronary heart disease. Methods: A total of 120 young and middle-aged patients with coronary heart disease were selected and randomly divided into a control group (n=60) and an intervention group (n=60). The control group implemented the conventional health education model, and the intervention group implemented the Green model health education. The blood lipid levels and HPLP-II scores of the health promotion lifestyle scale were compared between the 2 groups at 1, 3, and 6 months, respectively. Results: There was no significant difference in HPLP-II scores of blood lipid and health promotion lifestyle scale between the 2 groups at baseline and during 1 and 3 months (P>0.05). After 6 months, the blood lipid control of the intervention group was significantly better than that of the control group (P<0.05), health promotion lifestyle scale HPLP-II score improved to a good level. Conclusion: Implementing the Green model health education for young and middle-aged patients with coronary heart disease can effectively promote the formation of a healthy lifestyle and improve the healthy living standard of patients.
