The study investigated whether the co-occurrence of atherosclerotic cardiovascular disease (ASCVD), which contributes to reduced life expectancy in individuals with major depressive disorder (MDD), reflects a shared pathophysiology and which pathways are involved. Swedish national registry data were integrated with genomic analyses of circulating metabolites and proteins and within-pair analyses of metabolites measured in 14,500 twins. Among 2,619,213 individuals, clinically diagnosed MDD was associated with incident ischemic heart disease and cerebrovascular disease (hazard ratios of 1.73 and 1.93, respectively). Metabolite analyses identified an immunometabolic signature characterized by triglyceride-rich lipoproteins, increased fatty acid saturation, and inflammation; low-density lipoprotein cholesterol was not part of this signature. Genetic analyses at the protein level highlighted fibroblast growth factor 21, hepatocyte growth factor, and carboxylesterase 1, proteins involved in endothelial function and atherosclerosis; conditioning on these proteins reduced the genetic correlation between MDD and ischemic heart disease by 50%. To address MDD heterogeneity, genome-wide association studies were conducted for MDD with atypical energy-related symptoms (AERS+; increased weight and appetite, hypersomnia), MDD with the opposite symptom pattern (AERS), and a latent factor reflecting shared MDD–ASCVD susceptibility; genetic correlations with triglyceride-rich lipoproteins, glycoprotein acetyls, and C-reactive protein increased progressively from AERS through MDD and AERS+ to shared susceptibility (from 0.08 to 0.35 for triglycerides and from 0.04 to 0.32 for C-reactive protein), whereas correlations with lipoprotein particle size decreased. The findings point to opportunities for more targeted cardiovascular prevention. Bu çalışmaya nasıl atıf yapılır? APA 7: Bergstedt, J., et al. (2026, September 26).
