Abstract

BackgroundThe relation of lipoprotein subfractions with stable coronary artery disease (CAD) has not been fully investigated in the Chinese Han population.MethodsFour-hundred-and-thirteen consecutive patients without any lipid-lowering drug treatment were investigated. Patients were classified into two groups according to the angiographic results: CAD group (n=293) and non-CAD group (n=120). The high-density lipoprotein (HDL) and low-density lipoprotein (LDL) subfractions were analysed using the Quantimetrix Lipoprint system.ResultsThe data showed that the large HDL-cholesterol (HDL-C) level, large HDL subfraction percentage, and mean LDL particle size were significantly lower, while the small HDL-C level and HDL subfraction percentage, intermediate and small LDL-cholesterol (LDL-C) levels, and LDL subfraction percentages were higher in the CAD group compared with those in the non-CAD group. Interestingly, our results suggested that the small HDL-C level and HDL subfraction percentage as well as mean LDL particle size were independently associated with the presence of CAD assessed by logistic regression analysis (OR=1.136, 95%CI=1.018-1.268, p=0.022; OR=1.076, 95%CI=1.021-1.134, p=0.007; OR=0.946, 95%CI=0.898-0.997, p=0.040; respectively).ConclusionsSimilar to previous Western population studies, our data suggested a clear association between the lipoprotein subfractions and stable CAD presented as higher small HDL subfraction and smaller mean LDL particle size in Chinese Han patients.
