| Abstract: | Schizophrenia has been linked to an elevated cardiovascular risk profile and premature onset of cardiovascular disease. Quantifying epicardial adipose tissue (EAT) volume provides insight into its correlation with coronary artery disease (CAD) severity and associated risk factors. Previous research indicates higher pericardial adipose tissue in individuals with schizophrenia compared to non-schizophrenic counterparts. RBP4, FABP3, and FABP4 have been implicated in CAD pathogenesis. In this study, we examined the potential increase in EAT volume in individuals with chronic schizophrenia and aimed to elucidate the relationship between circulating levels of RBP4, FABP3, and FABP4 with EAT volume and coronary artery calcium score within this cohort. We recruited 186 consecutive patients with chronic schizophrenia and utilized enzyme-linked immunosorbent assay to assess plasma concentrations of RBP4, FABP3, and FABP4. Cardiac multislice computed tomography measured EAT volume and coronary artery calcium scores. Significantly higher EAT volume in patients with chronic schizophrenia compared to controls. RBP4 associated positively with metabolic factors and EAT volumes, while FABP3 associated positively with creatinine and coronary atherosclerosis markers. FABP4 showed positive associations with metabolic factors, hypertension, and EAT volumes, but negative associations with HDL-C and eGFR. Logistic regression identified RBP4 and FABP4 as independent factors associated with increased EAT volumes, even after adjusting for known biomarkers. Both RBP4 and FABP4 were significantly associated with metabolic syndrome components and EAT volume. This study elucidates the association between chronic schizophrenia and augmented EAT volume, suggesting plausible correlations with CAD-related health complications through RBP4 and FABP4 pathways.
