BACKGROUND: High-density lipoprotein (HDL) consists of heterogeneous particles with a variety of structures and functions. Its role in atherosclerosis has been gradually recognized. Studies have shown dysfunction of small HDL in patients with coronary artery disease (CAD). Monocytes play an important role in atherosclerosis, which can be divided into 3 subgroups based on the expression of surface markers CD14 and CD16. This study aimed to investigate the association between HDL and monocyte subsets in CAD patients. 
MATERIAL AND METHODS: A total of 90 patients with stable CAD were selected in this study. Monocytes were divided into classical monocytes (CM, CD14++CD16-), intermediate monocytes (IM, CD14++CD16+), and non-classical monocytes (NCM, CD14+CD16++). HDL components in serum were determined by high-resolution polyacrylamide gel electrophoresis (detected by Quantimetrix HDL Lipoprint system, referring to HDL subfractions analysis: A new laboratory diagnostic assay for patients with cardiovascular diseases and dyslipoproteinemia). 
RESULTS: Serum level of small HDL was positively correlated with circulating proinflammatory NCM (r=0.30; p=0.004), negatively correlated with CM, and not correlated with IM. We also found that disease severity was not associated with diabetes mellitus, glycosylated hemoglobin, hypertension, smoking history, or statin dosage. 
CONCLUSIONS: Our study confirmed that small HDL level is associated with an increase in NCM and a decrease in CM, suggesting the proinflammatory relationship between small HDL and intrinsic immune function during the progression of stable CAD.
