Abstract

Background: Studies have shown the association of mood disorders and endothelial dysfunction, and increased risk of cardiovascular disease; however, mediatory mechanisms are not entirely clarified in this regard. We investigated the relationship between depression/anxiety symptoms with systemic inflammation and endothelial function. Materials and Methods: This cross-sectional study was performed in 2011 on employees of an oil company located in the Isfahan city (central Iran). Participants were selected with clustered random sampling. Anxiety and depression were evaluated by Hospital Anxiety Depression Scale (HADS). Systemic inflammatory status was evaluated by measuring sensitive C-reactive protein (high sensitive-CRP). To evaluate the endothelial function flow-mediated dilation (FMD) was measured. Results: During the study period, 254 participants (mean age = 51.4 ± 6.1 years) were evaluated. No significant relationship was found between high sensitive-CRP or FMD and any of the variables of anxiety or depression. In multivariate analysis, by controlling the possible confounding factors, no association was found between anxiety score, depression, or the overall score of HADS with high sensitive-CRP or FMD. After the separate analysis of patients with and without diabetes, depression score was correlated inversely with FMD among patients with diabetes (r = 0.525, P = 0.021). Conclusion: According to the results, in the studied population, there was no relationship between anxiety/depression with systemic inflammation or endothelial dysfunction, while in individuals with diabetes, depression was associated with endothelial dysfunction. In this regard more cohort studies are recommended.
