Methods A total of 1455 consecutive patients not treated with lipid-lowering drugs and undergoing coronary angiography were enrolled in this cross-sectional study. A mediation analysis was used to detect the underlying role of apoCⅢ in the association of inflammation with metabolic syndrome(MetS). Results Patients with MetS showed higher levels of apoCⅢ [95.1(73.1-131.4) vs. 81.7(58.6-112.4) μg/mL, P 〈 0.001] and inflammatory markers [high sensitivity C-reactive protein, 1.7(0.8-3.4) vs. 1.1(0.5-2.2) mg/L; white blood cell count,(6.48 ± 1.68) vs.(6.11 ± 1.67) × 10~9/L]. The levels of apoCⅢ and inflammatory markers increased with the number of metabolic risk components(all P 〈 0.001). Furthermore, apoCⅢ levels were associated with virtually all individual MetS risk factors and inflammatory markers(all P 〈 0.05). Importantly, the prevalence of MetS in each metabolic disorder rose as apoCⅢ levels increased(all P 〈 0.05). Mediation analysis showed that apoCⅢ partially mediated the effect of inflammation on MetS independently from triglycerides. Conclusion Plasma apoCⅢ levels were significantly associated with the development and severity of MetS, and a role of apoCⅢ in the effect of inflammation on the development of MetS was identified.展开更多

Atherosclerotic arteries obtained at autopsy from patients who died suddenly of cardiac causes indicate that pregnancyassociated plasma protein-A ( PAPP-A ) was abundantly expressed in plaque cells and in the extracellular matrix of ruptured and eroded unstable plaques, but not in stable plaques. Here we examined circulating PAPP-A levels in patients with ACS in order to evaluate its potential use in identifying vulnerable patients.展开更多
