[…] We studied a cohort of 135 CAD patients who were regularly visiting the outpatient clinic and receiving medication at the Wonkwang University Hospital Cardiovascular Center. This research was conducted from March to August 2016. To select subjects who had higher risks of depression, trait anxiety, and anger, we administered the Personality Assessment Inventory (PAI). The number of people used in the study was determined by using G*Power program 3.1.4 (Heinrich-Heine-Universität Düsseldorf, Düsseldorf, Germany) and the calculated subject when applying α = 0.05, power 80%, and effect size = 0.25 was 135. A total of 70 participants scored over 70 points in the T-scores on the sub-scales measure of depression (DEP), anxiety (ANX), and aggression (AGG). After the 26 subjects were excluded, 44 subjects were split into two groups: 21 belonged to the MBAT group, and 23 to the control group. Before the study, participants were provided detailed explanations regarding study purposes and procedures, based on which they signed research participation agreements indicating consent. Participants were randomly assigned to the MBAT or control group by flipping a coin. As 6 in the MBAT group and 1 in the control group dropped out, only 37 remained as final subjects (). [...] According to intent-to-treat (ITT) principle, the data for all the subjects were analyzed. Both Student's t-test and χ2 test were used for the analysis of demographic and clinical variables. Repeated measures of analysis of variance (ANOVA) were used to test both interaction and main effects of MBAT between the two groups. All the statistical analyses were conducted by IBM SPSS statistics 21.0 (SPSS Inc., Chicago, IL, USA). […]
