Effect of Eye Movement Desensitization and Reprocessing (EMDR) on Depression in Patients With Myocardial Infarction (MI)

BACKGROUND Coronary heart disease is the most important cause of death and inability in all communities. Depressive symptoms are frequent among post-myocardial infarction (MI) patients and may cause negative effects on cardiac prognosis. This study was conducted to identify efficacy of EMDR on depression of patients with MI. METHODS This study is a clinical trial. Sixty patients with MI were selected by simple sampling, and were separated randomly into experimental and control groups. To collect data, demographic questionnaire and Beck Depression Questionnaire were used. In experimental group, EMDR therapy were performed in three sessions alternate days for 45-90 minutes, during four months after their MI. Depression level of patients was measured before, and a week after EMDR therapy. Data were analyzed using paired -t- test, t-test, and Chi-square. RESULTS The mean depression level in experimental group 27.26±6.41 before intervention, and it was 11.76±3.71 after intervention. Hence, it showed a statistically significant difference (P<0.001). The mean depression level in control group was 24.53±5.81 before intervention, and it was 31.66±6.09 after intervention, so it showed statistically significant difference (P<0.001). The comparison of mean depression level at post treatment, in both groups showed statistically significant difference (P<0.001). CONCLUSION EMDR is an effective, useful, efficient, and non-invasive method for treatment and reducing depression in patients with MI.
