ABSTRACT
Objective To investigate the relationship between lipoprotein-associated phospholipase A2(Lp-PLA2) activity and the severity of coronary artery diseases .Methods A case-control study was conducted to select 231 patients with positive coronary angiography results in Beijing Huaxin Hospital .They were divided into two groups (untreated goup147 cases; the medication group84 cases) according to whether taking statins.99 cases were included in the healthy control group .In the untreated group, all male patients were grouped according to the number of diseased coronary branches (43 cases were in single vessel lesion group and 52 cases were in multi vessel disease group ) or to the Gensini score (32 cases were in low score group, 36 cases were in middle score group and 27 cases were in high score group ).The clinical data were collected by detecting serum atherosclerotic markers such as Lp-PLA2, total cholesterol (CHOL), low-density lipoprotein (LDL).The number of vessels involved in coronary artery disease , the position of the lesion and the degree of stenosis were confirmed by percutaneous coronary intervention ( PCI).Statistical evaluations were performed using t-test, variance analysis, Mann-Whitney U test and Spearman correlation analysis.Results The differences among untreated group , the medication group and the control group were statistically significant, of which the Lp-PLA2 level was (561.9 ±158.5) U/L, (373.2 ±124.7) U/L and (467.4 ±130.4) U/L respectively.Compared with single branch disease group , the Lp-PLA2 level in the multiple branches disease group was increased dramatically .Additionally, the level of Lp-PLA2 in high Gensini score group was (618.7 ±165.4) U/L, significantly higher than the low score group (517.3 ± 191.7) U/L.Conclusion Lp-PLA2 activity was associated with the severity of Coronary Artery Diseases, which can provide the evidence for the follow-up treatment programs.
