Correlates and Escitalopram Treatment Effects on Sleep Disturbance in Patients with Acute Coronary Syndrome: K-DEPACS and EsDEPACS.


ABSTRACT: To investigate the correlates of sleep disturbance and to assess escitalopram treatment effects of depression on sleep disturbance in patients with acute coronary syndrome (ACS).A cross-sectional study in patients with ACS within 2 w post-ACS, and a 24-w double-blind controlled trial of escitalopram against placebo for patients with ACS who have comorbid depressive disorders.A university hospital in South Korea.There were 1,152 patients with ACS who were consecutively recruited. Of 446 patients with comorbid depressive disorders, 300 were randomized to the trial.Sleep disturbance was evaluated by the Leeds Sleep Evaluation Questionnaire. Demographic and clinical characteristics were assessed, including cardiovascular risk factors, current cardiac status, and depressive symptoms. Depressive symptoms were most strongly and consistently associated with sleep disturbance. In addition, older age, female sex, hypertension, and more severe ACS status were associated with certain aspects of sleep disturbance. Escitalopram was significantly superior to placebo for improving sleep disturbance over the 24-w treatment period. These effects were substantially explained by improvement in depressive symptoms.Depression screening is indicated in patients with acute coronary syndrome with sleep disturbance. Successful treatment of depression has beneficial effects on sleep outcomes in these patients.ClinicalTrial.gov identifier for the 24-w drug trial, NCT00419471.
