Depression and Associated Factors in Patients with Implantable Cardioverter-Defibrillators.

Background: Psychological problems such as depression constitute a dilemma that patients with the implantable cardioverter-defibrillator (ICD) usually encounter and may impact their quality of life. The purpose of this study was to evaluate the prevalence of depression among adults with the ICD and the relationship between depression and associated factors. Methods: Totally, 115 individuals with the ICD participated in this cross-sectional study in Tehran, Iran, and depression and other related risk factors were evaluated in them. Two questionnaires, one for demographic characteristics and the Beck Depression Inventory, were applied for data acquisition. The data were analyzed, and the factors associated with depression in the patients with the ICD were assessed. Results: The mean age of the study population was 59.85 ± 11.46 years. Males comprised 88 (76.5%) and females 27 (23.5%) of the patients. The multivariate analysis on the 115 patients revealed that frequency of ICD shocks (OR = 1.08, 95%CI: 1.02 - 1.10), male sex (OR = 2.28, 95%CI: 1.027 - 5.07), more hospital admissions (OR = 1.19, 95%CI: 1.11 - 1.25), smoking cessation (OR = 9.8, 95%CI: 4.48 - 20.07), presence of ICD shocks (OR = 4.5, 95%CI: 2.45 - 7.38), dyslipidemia (OR = 2.8, 95%CI: 1.22 - 4.95), and family history of depression (OR = 6.4, 95%CI: 3.0 - 13.46) were significantly and independently associated with the Beck score classifications. Conclusion: These findings suggest that a poor psychosocial outcome in patients with the ICD may occur as a result of a variety of associated factors, most of which are predictable and preventable.
