ABSTRACT
Objective To observe the correlation between lipoprotein-associated phospholipase A2(Lp-PLA2) levels and coronary artery disease (CAD), extent of angiographic coronary artery lesions and risk factors of CAD in the elderly. Methods Plasma levels of Lp-PLA2, triglyceride (TG), total cholesterol(TC), low density lipoprotein(LDL-C), high density lipoprotein cholesterol (HDL-C) and high sensitivity C-reactive protein(hs-CRP) were measured in 67 elderly patients with angiographic CAD meanwhile in 23 normal controls without angiographic coronary artery lesions. The extent of coronary artery lesions was evaluated according to the number of vessel lesions (divided into single, double and triple-vessel lesions) and Gensini scoring system. Then the relationship between Lp-PLA2 and CAD was assessed. Results The plasma levels of Lp-PLA2 were significantly higher in the CAD group than in the controls [(352.7 ± 129.0) vs. (204.0 ± 59. 7) μg/L, P < 0. 01]. Lp-PLA2 levels increased with the number of coronary artery lesions and Gensini score, then were positively correlated with age(r= 0. 25, P<0. 05) ,TC(r=0. 33, P<0. 01) ,LDL-C(r=0.27, P< 0. 05),apoB(r=0. 36, P<0. 01). The levels of LP-PLA2 and LP(a) were associated with CAD by using stepwise regression analysis. Conclusions In the eldly, the levels of LP-PLA2 are much higher in angiographic CAD, and these may reflect the severity of CAD. LP-PLA2 is a risk factor for CAD.
