The Predictive Value of Elevation in Serum Oxidized Low Density Lipoprotein for Premature Coronary Artery Disease / 天津医药

ABSTRACT

Objective To investigate the characteristics of serum oxidized low density lipoprotein (ox-LDL) and traditional cardiovascular risk factors of premature coronary artery disease (PCAD). Methods Sixty-six patients with coro-nary atrery disease (CAD) confirmed by angiography were selected to be PCAD group, and 56 patients with normal coronary artery confirmed by angiography were included in control group. The serum levels of ox-LDL, high density lipoprotein choles-terol (HDL-C), triglyceride (TG), creatinine (SCr), uric acid (UA), other serum biochemical indicators and differences of the proportions of male, hypertension, diabetes, smoking history and family history of CAD were compared between two groups. Results (1)There were higher serum values of ox-LDL, TG, SCr, UA, fasting blood glucose (FBG) and proportion of male pa-tients in PCAD group than those of control group (P＜0.05), but there was a lower plasma level of HDL-C in PCAD group than that of control group (P＜0.05). There were significant differences in other indicators between two groups. (2) There were positive correlations between UA, SCr and ox-LDL ( rs were 0.243 and 0.186 respectively, P were 0.006 and 0.034 respective-ly). (3)The logistic regression analysis showed that ox-LDL, HDL-C and SCr were influential factors to PCAD(OR were 1.155, 0.143 and 1.052 respectively). Conclusion Elevations of ox-LDL, HDL-C and SCr are independent predictors of PCAD.
