Effects of a psychoeducational intervention for secondary prevention in Korean patients with coronary artery disease: a pilot study.

ABSTRACT

This intervention study was designed to examine whether a 12-week psychoeducational intervention influenced recurrent cardiac events, symptom experience and treatment adherence of patients with coronary artery disease. Fifty-eight patients were randomized to either the intervention or the control group. Measures were taken at baseline, after intervention, and at 6-month follow-up. Recurrent cardiac events included revascularization, rehospitalization, emergency room visits and mortality. Symptom experiences were measured using the Seattle Angina Questionnaire-Korean and Hospital Anxiety and Depression Scale. Treatment adherence included health behaviours, routine check-up and medication adherence. At 6-month follow-up, the intervention group had significantly better physical functions and lower anxiety and depressive symptoms. Treatment adherence was also significantly higher in the intervention group than the control group. No significant difference was noticed in the incidence of recurrent cardiac events between the groups. A longer follow-up study is needed to determine the long-term effects on the prevention of recurrent cardiac events.
