Abstract：Objective To explore the application effect of health education based on a WeChat platform co-constructed by a medical consortium in the secondary prevention of outpatients with coronary heart disease(CHD),aiming to provide a refer-ence for formulating secondary prevention strategies for these patients.Methods A total of 126 CHD patients who met the study criteria and visited the outpatient department of West China Hospital,Sichuan University,from December 2021 to June 2023 were selected and randomly assigned to a control group(n=63)and an observation group(n=63)using the ran-dom envelope method.The control group received routine outpatient follow-up and education,while the observation group received health education based on a WeChat platform co-constructed by a medical consortium.The medication adherence,self-management ability,quality of life,cardiac function,exercise tolerance,and incidence of adverse cardiovascular events were compared between the two groups before and after the intervention.Results Before intervention,no significant differ-ences were noted in the Morisky Medication Adherence Scale-8(MMAS-8)and Coronary Heart Disease Self-Management Scale(CSMS)scores between the two groups(P＞0.05).The MMAS-8 and CSMS scores in both groups increased signifi-cantly after intervention,and the observation group had significantly higher scores than the control group(P＜0.05).Be-fore intervention,no significant differences were observed in the five dimensions of the Seattle Angina Questionnaire(SAQ)-physical limitation,angina stability,angina frequency,treatment satisfaction,and disease perception-between the two groups(P＞0.05).The scores for all five dimensions of the SAQ in both groups showed a significant increase after inter-vention,and the observation group had significantly higher scores than the control group(P＜0.05).Before intervention,no significant differences were found in stroke volume(SV),left ventricular ejection fraction(LVEF),or 6-minute walking distance(6MWD)between the two groups(P＞0.05).The SV,LVEF,and 6MWD in both groups were significantly in-creased after intervention,and the observation group had significantly greater improvements than the control group(P＜0.05).The incidence of adverse cardiovascular events during the intervention in the observation group was significantly low-er than that in the control group[6.35％(4/63)vs.19.04％(12/63);X2=4.582,P=0.032].Conclusion The applica-tion of health education based on the WeChat platform co-constructed by a medical consortium in the secondary prevention of outpatients with CHD has marked effects.It can effectively improve patients'medication adherence and self-management a-bility,promote their quality of life,cardiac function,and exercise tolerance,and reduce the risk of adverse cardiovascular e-vents,holding promise for clinical promotion and application.
