Abstract： Objective:To explore the application of health education guided by transtheoretical model(TTM)in patients with chronic heart failure(CHF)during the nuoxintuo treatment.Methods:A total of 86 patients with chronic CHF diagnosed in our hospital from July 2021 to March 2023 were randomly divided into observation group(n=43)and control group(n=43).All patients were treated with noricept.The patients in the control group were treated with routine nursing during the treatment period.The patients in the observation group were treated with TTM-guided health education during the treatment period,and the intervention lasted for 3 months.The cognitive level[heart failure knowledge questionnaire(AHFKT),self-efficacy scale(GSES),CHF self-management scale],burden scale(ZBI),cardiac function and exercise endurance,quality of life were compared between the two groups.Results:After intervention,the AHFKT score,GSES score and self-management ability score of the observation group were higher than those of the control group(P<0.05);the scores of each dimension of ZBI in the observation group were lower than those in the control group(P<0.05);the LVESD and LVEDD diameters of the observation group were lower than those of the control group,and LVEF and 6 min walking distance were higher than those of the control group(P<0.05);the scores of each dimension and total score of MLHFQ in the observation group were lower than those in the control group(P<0.05).Conclusion:During the treatment of CHF patients with noricept,the application of TTM-guided health education can effectively improve the patient's cognition of the disease,improve the patient's heart function and quality of life.
