[摘 要] 目的:量化评估脂蛋白相关磷脂酶A2(lipoprotein associated phospholipase A2,Lp⁃PLA2)水平预测冠脉病变严重程
度的效果。方法:入选行冠状动脉造影及Lp⁃PLA2检测的患者共123例,评估Lp⁃PLA2对急性冠脉综合征(acute coronary syn⁃
drome,ACS)、多支病变及SYNTAX Ⅱ评分的预测价值。结果:Lp⁃PLA2与冠心病诊断、多支病变、SYNTAX Ⅱ评分等有相关性
(P均<0.05)。Lp⁃PLA2诊断ACS和多支病变的灵敏度较高(分别为90.9%、80.0%),诊断SYNTAX Ⅱ评分≥23分及≥33分的特
异度较高(分别为81.7%、87.4%)。Lp⁃PLA2是多支病变、SYNTAX Ⅱ评分≥23分及≥33分的独立危险因素(OR分别为1.004、
1.003及1.004,P均<0.05)。亚组分析显示,Lp⁃PLA2水平升高可预测高血压患者多支病变(OR=2.800,P < 0.05)、高血压与糖
尿病患者SYNTAX Ⅱ评分≥23分的风险较高(高血压亚组OR=3.586;糖尿病亚组OR=18.000,P均<0.05)。结论:Lp⁃PLA2可以
有效预测冠脉病变严重程度,尤其是诊断ACS和多支病变的灵敏度和SYNTAX Ⅱ评分≥23分及≥33分的特异度较高,对高血
压及糖尿病患者的冠脉病变预测价值更大。

[Abstract] Objective:To quantitative assess the effect of lipoprotein associated phospholipase A2(Lp⁃PLA2)level in predicting the
severity of coronary lesions. Methods:A total of 123 patients who underwent coronary angiography and Lp ⁃ PLA2 detection were
enrolled to evaluate Lp⁃PLA2 level in predicting acute coronary syndrome(ACS),multi⁃vessel lesions and SYNTAX Ⅱ score. Results:
Lp⁃PLA2 was correlated with the diagnosis of coronary artery disease,multi⁃vessel lesions and SYNTAX Ⅱ score(all P < 0.05). Lp⁃
PLA2 had high sensitivity in predicting ACS(90.9%)and multi⁃vessel lesions(80.0%),high specificity in predicting SYNTAX Ⅱ
score ≥23(81.7%)and ≥33(87.4%). Lp⁃PLA2 was an independent risk factor for multi⁃vessel lesions and SYNTAX Ⅱ score ≥23
and ≥33(OR=1.004,1.003 and 1.004,respectively,all P < 0.05). Subgroup analysis showed that the higher concentration of Lp⁃PLA2
predicted the higher risk of multi⁃vessel lesions in hypertension(OR=2.800,P < 0.05)and higher risk of SYNTAX Ⅱ score ≥23 in
hypertension and diabetes patients(OR=3.586 and 18.000,respectively,both P < 0.05). Conclusion:Lp⁃PLA2 can effectively predict
the severity of coronary lesions,especially the sensitivity of ACS diagnosis and multi⁃vessel lesions and the specificity of SYNTAX Ⅱ
score ≥23 and ≥33. The predictive value of Lp⁃PLA2 for coronary lesions is greater in hypertension and diabetes patients.
