    Abstract:
    BACKGROUND: Data are limited on associations between apolipoprotein B (Apo B) and cerebral atherosclerosis. OBJECTIVE: Our study aimed to estimate associations between discordant Apo B with low-density lipoprotein cholesterol (LDL-C) or non-high-density lipoprotein cholesterol (Non-HDL-C) and the odds of the presence and burden of intra-/extra-cranial atherosclerotic plaques. METHODS: This cross-sectional study was based on the baseline survey from the PolyvasculaR Evaluation for Cognitive Impairment and vaScular Events (PRECISE) study, a population-based prospective cohort study. Participants with complete baseline data but without taking lipid-lowering medication were included in this analysis. Discordant Apo B with LDL-C or Non-HDL-C were defined by residuals and cut-off values (LDL-C: 3.4 mmol/L, Non-HDL-C: 4.1 mmol/L). We used binary and ordinal logistic regression models to explore associations between discordant Apo B with LDL-C or Non-HDL-C and the presence and burden of intra-/extra-cranial atherosclerotic plaques. RESULTS: A total of 2,943 participants were enrolled in this study. Discordantly high Apo B with LDL-C was associated with an increased odds of the presence of intracranial atherosclerotic plaque [odds ratio (OR),1.28; 95%CI,1.01-1.61], intracranial atherosclerotic burden [common odds ratio (cOR), 1.31; 95%CI,1.04-1.64], the presence of extracranial atherosclerotic plaque (OR, 1.37; 95%CI,1.14-1.66), and extracranial atherosclerotic burden (cOR, 1.32; 95%CI,1.10-1.58) compared with the concordant group. Discordantly low Apo B with Non-HDL-C was associated with decreased odds of the presence and burden of intra-/extra-cranial atherosclerotic plaques. CONCLUSION: Discordantly high Apo B with LDL-C or Non-HDL-C were associated with an increased odds of the presence and burden of intra-/extra-cranial atherosclerotic plaques. This demonstrated that discordantly high Apo B might be important for early assessment of risk of cerebral atherosclerotic plaques in addition to LDL-C and Non-HDL-C.
