ABSTRACT
BACKGROUND:
The exact role of different high-density lipoprotein (HDL) subfractions in the pathogenesis of coronary artery disease (CAD) has not yet been fully explored. The aim of the present study was to examine the relationship between HDL subfractions and the severity of CAD in patients without statin therapy.METHODS:
A total of 382 consecutive patients (mean 55.36 ± 11.30 years of age) who underwent coronary angiography from angina-like chest pain were investigated. Patients were classified into 2 groups according to the angiographicresults:
a CAD group (n = 283) and a control group (n = 99). The distribution of HDL subfractions was analyzed using a Quantimetrix Lipoprint HDL system. CAD severity was measured by Gensini score (GS).RESULTS:
Compared with the control group, HDL-cholesterol (HDL-C), large HDL-C level, and the large HDL subfraction percentages in the CAD group were significantly lower (P = .002, P < .001, P < .001, respectively). Meanwhile, a small HDL-C level and the percentage of small HDL subfraction were significantly higher (P = .003, P < .001, respectively). Correlation analysis showed that the percentage of a large HDL subfraction was negatively correlated with GS (ß = -0.191, P = .005), whereas the percentage of a small HDL subfraction positively correlated with GS (ß = 0.145, P = .023) in patients with CAD.CONCLUSIONS:
Small HDL subfraction was associated with the presence of CAD, whereas the percentage of large HDL and small HDL subfraction was negatively and positively associated with the severity of CAD, respectively.Palavras-chave
