Methods A descriptive correlational and cross-sectional design was used. Subjects with CADs were
recruited from outpatient clinics of three academic medical centers. The cardiac knowledge, cardiac self- efficacy, and health behaviors were measured by Coronary Heart Disease Awareness and Knowledge Questionnaire, Cardiac Self-Efficacy Scale, and Health-Promoting Lifestyle Profile II respectively. The data collected were statistically analyzed by descriptive statistics, t test, Kruskal-Wallis test, analysis of vari-ance, Pearson’s correlation analysis, and the hierarchical multiple regression analysis.
