Abstract The purpose of this study was to investigate the moderating effect of lifestyle and Type D personality on the relation between metabolic syndrome and severity of coronary artery disease. This study was descriptive correlation study to provide a basic data for practical knowledge and direction of nursing intervention. The subjects of this study were 111 patients who were diagnosed as coronary artery disease in one university hospital and selected outpatient for cardiology treatment. The data collection period was from January 2, 2017 to March 16, 2017. The research tools were diagnostic criterias for metabolic syndrome(Alberti et al., 2009; KSSO, 2014), lifestyle evaluation tool for patients with metabolic syndrome(Kang, 2010), The Korean Type D scale-14(Lim et al, 2011). Data were analyzed using frequency and percentage, mean and standard deviation, t-test, one-way ANOVA, Pearson's correlation coefficient, regression analysis, and two-way ANOVA using SPSS WIN 22.0 program.

The results of this study were as follows. 1. The severity of coronary artery disease was statistically significant in the subjects' marital status, diagnosis, and comorbidity. In the married group, the severity was 1.30±1.02, which was higher than the unmarried group 1.00±0.00. The mean of myocardial infarction group was 2.27±0.91, which was higher than the 1.15±0.97 in the angina pectoris group. In patients with comorbidities, the mean of patients with comorbidities was 1.40±1.02, which was higher than that of patients without comorbidities 0.80±0.83. 2. Of the total subjects, 48.6% had metabolic syndrome and the average of lifestyle was 82.41±17.60. Type D personality was 28.8% and the mean of severity of coronary artery disease was 1.29±1.01. 3. The severity of coronary artery disease was positively correlated with the presence of metabolic syndrome(r=.26, p=.006) and Type D personality(r=.49, p<.001). There was a significant negative correlation on the relation between the severity of coronary artery disease and lifestyle. The higher the severity of coronary artery disease, the lower the lifestyle(r=-.54, p<.001). 4. Lifestyle had moderating effect of 33.3% on the metabolic syndrome and severity of coronary artery disease(R² change=.047), but Type D personality had no moderting effect(F=0.130, p=.719).

In order to prevent the transition from metabolic syndrome to coronary artery disease, it was necessary to improve lifestyle by setting priorities or weighting among various areas. Type D personality didn't have a direct effect on the severity of coronary artery disease, but it might be a variable affecting lifestyle, so tailored intervention according to personality characteristics was necessary.
