Background: Mood disorders have been associated with a variety of cardiovascular disease (CVD) risk factors, including inflammation and large arterial stiffness, particularly while depressed, although longitudinal studies have been limited. Materials and Methods: With measurements at baseline and 8 weeks, the researchers prospectively assessed mood, levels of inflammatory markers (high-sensitivity C-reactive protein and tumor necrosis factor-alpha [TNF-α]), serum lipids, and large arterial stiffness in a cohort of 26 participants with a diagnosis of a mood disorder, enriched for current depression. Depressive symptoms were measured using the Montgomery–Šsberg Depression Rating Scale (MADRS) at baseline and 8 weeks. Associations between depressive symptoms and other measures were assessed using linear mixed models, unadjusted and adjusted for age and body mass index. Results: The mean age of the participants (n = 26) was 41.6 (standard deviation [SD] 12.8) years, and 81% were female. During the study, there was a mean (SD) MADRS score improvement of 9.5 (9.4) from baseline to 8 weeks. Reductions in the primary outcome of tumor necrosis factor-α with improvement in depression fell short of statistical significance (P = 0.076). In secondary analyses, there was a statistically significant association between improved cholesterol ratio (P = 0.038) and triglycerides (P = 0.042) with improvement in depression. There was no statistically significant change in large arterial stiffness during the study. Conclusion: Improved depressive symptoms were associated with improved cholesterol ratios even after adjustment, suggesting a possible mechanism by which acute mood states may influence CVD risk. Future longitudinal studies with extended and intensive follow-up investigating CVD risk related to acute changes and persistence of mood symptoms are warranted. |
