Effectiveness of micro-lecture based cardiac rehabilitation education on health status in individuals with coronary artery disease: A randomized clinical trial

Abstract

Objective To explore the effectiveness of the micro-lecture education on the ability of self-management and lifestyle changes in patients with coronary artery disease. Design A randomized control trial with a 12-week follow-up. Setting Cardiology wards of a large Chinese University Hospital. Subjects One hundred eligible inpatients with coronary artery disease were recruited. Intervention Intervention group received the micro-lecture education, while the control group received the traditional cardiac rehabilitation education. Main measures Primary outcome of the ability of coronary self-management was assessed by the Coronary self-management scaleat baseline, 12-week after discharge. Secondary outcomes of smoking status, exercise status, and six-minute walk distance were evaluated at the baseline, week4 and week 12 after discharge. The chi-square test,Fisher's exact test, group t-test and the repeated measure variance were used for the data analysis. Results Eighty-nine of 100 eligible participants responded, and mean age was 60.2 ± 11.3 years.After the intervention, the mean score of the coronary self-management scale (3.84 ± 0.36) was higher than that in the control group (2.78 ± 0.57).At week 12, the rate of re-smoked in the intervention group (6%) was significantly lower than that in the control group (43%),the frequency of the exercise (85%), and the 6MWD (495.55 ± 85.94) in the intervention group were better than the control group. Conclusion Micro-lecture education program presented a positive effect on promoting the ability of self-management, and apotential effect on the therapeutic lifestyle changes for the coronary artery disease patients.
