Obstructive sleep apnea/hypopnea syndrome and poor response to sertraline in patients with coronary heart disease
Abstract
OBJECTIVE: Evidence from several clinical trials in patients with coronary heart disease suggests that depression that does not respond to treatment is associated with a particularly high risk of adverse cardiac outcomes. The purpose of this study was to determine whether obstructive sleep apnea/hypopnea syndrome (OSAHS) is associated with a poor response to antidepressant medication in patients with coronary heart disease.
METHOD: This was a secondary analysis of data from a randomized, double-blind, placebo-controlled clinical trial of omega-3 fatty-acid augmentation of sertraline for depression in patients with coronary heart disease. Patients with documented coronary heart disease were recruited between May 2005 and December 2008 from cardiology practices in St Louis, Missouri, and through cardiac diagnostic laboratories affiliated with Washington University School of Medicine, St Louis, Missouri. One hundred five patients (mean age = 58 years) with coronary heart disease and current major depressive disorder (DSM-IV) were randomized to receive sertraline plus either omega-3 or placebo for 10 weeks. Cyclical heart-rate patterns associated with OSAHS were detected via ambulatory electrocardiography prior to treatment. Symptoms of depression were measured at baseline and follow-up with the Beck Depression Inventory-II (BDI-II) and the 17-item Hamilton Depression Rating Scale (HDRS-17). The primary endpoint was the BDI-II score at 10 weeks.
RESULTS: Thirty of the 105…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 105 participants or records.
