目的探讨冠状动脉粥样硬化性心脏病(冠心病)患者血浆脂蛋白相关磷脂酶 A2(Lp-PLA2)水平与冠状动脉粥样斑块稳定性和冠状动脉病变程度的关系。方法选取2011年5-12月在中日友好医院接受冠状动脉造影( CAG)的患者254例,根据CAG结果分为冠心病组( n=206)和排除冠心病的对照组(n=48)。冠心病组按临床类型分为稳定型心绞痛(SAP)、不稳定型心绞痛(UAP)和急性心肌梗死( AMI)3个亚组;按冠状动脉病变支数可分为单支病变、双支病变和三支病变3个亚组;按冠状动脉Gensini积分可分为0~19分、20~39分和≥40分3个亚组。所有患者应用酶联免疫吸附法测定血浆Lp-PLA2水平,同时收集患者年龄、性别、体重指数、高血压病史、糖尿病病史、吸烟史等临床资料及总胆固醇、三酰甘油、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、高敏C反应蛋白(hs-CRP)等实验室数据。结果①冠心病组血浆Lp-PLA2水平明显高于对照组[(180±37)μg/L比(160±44)μg/L, P<0.01]。②SAP、UAP、AMI亚组的血浆Lp-PLA2水平均高于对照组,差异均有统计学意义[(183±38)、(178±34)、(181±38)μg/L比(160±44)μg/L,均P<0.05],但SAP、UAP、AMI亚组之间的差异无统计学意义(P>0.05)。③冠心病组中,随着病变支数和Gensini积分的增加,血浆Lp-PLA2水平呈逐渐升高趋势,各亚组Lp-PLA2水平均高于对照组,差异有统计学意义[病变支数冠状动脉单支、双支、三支病变各亚组(177±41)、(182±32)、(183±35)μg/L和Gensini积分0~19分、20~39分、≥40分各亚组(175±38)、(179±38)、(182±36)μg/L比(160±44)μg/L,均P<0.05],但各亚组间差异无统计学意义(P>0.05)。④血浆Lp-PLA2水平与年龄、体重指数、总胆固醇、三酰甘油、LDL-C、HDL-C、hs-CRP、高血压病史、糖尿病病史、吸烟史均无明显相关性。⑤年龄、吸烟史、血浆Lp-PLA2水平是冠心病的独立危险因素。 LDL-C、hs-CRP、血浆Lp-PLA2与Gensini积分独立相关。结论血浆Lp-PLA2水平在冠心病患者中明显升高,是冠心病的独立危险因素,与冠状动脉的狭窄程度有一定关系,但血浆Lp-PLA2水平与动脉粥样斑块稳定性的关系尚需进一步研究。
目的探討冠狀動脈粥樣硬化性心髒病(冠心病)患者血漿脂蛋白相關燐脂酶 A2(Lp-PLA2)水平與冠狀動脈粥樣斑塊穩定性和冠狀動脈病變程度的關繫。方法選取2011年5-12月在中日友好醫院接受冠狀動脈造影( CAG)的患者254例,根據CAG結果分為冠心病組( n=206)和排除冠心病的對照組(n=48)。冠心病組按臨床類型分為穩定型心絞痛(SAP)、不穩定型心絞痛(UAP)和急性心肌梗死( AMI)3箇亞組;按冠狀動脈病變支數可分為單支病變、雙支病變和三支病變3箇亞組;按冠狀動脈Gensini積分可分為0~19分、20~39分和≥40分3箇亞組。所有患者應用酶聯免疫吸附法測定血漿Lp-PLA2水平,同時收集患者年齡、性彆、體重指數、高血壓病史、糖尿病病史、吸煙史等臨床資料及總膽固醇、三酰甘油、低密度脂蛋白膽固醇(LDL-C)、高密度脂蛋白膽固醇(HDL-C)、高敏C反應蛋白(hs-CRP)等實驗室數據。結果①冠心病組血漿Lp-PLA2水平明顯高于對照組[(180±37)μg/L比(160±44)μg/L, P<0.01]。②SAP、UAP、AMI亞組的血漿Lp-PLA2水平均高于對照組,差異均有統計學意義[(183±38)、(178±34)、(181±38)μg/L比(160±44)μg/L,均P<0.05],但SAP、UAP、AMI亞組之間的差異無統計學意義(P>0.05)。③冠心病組中,隨著病變支數和Gensini積分的增加,血漿Lp-PLA2水平呈逐漸升高趨勢,各亞組Lp-PLA2水平均高于對照組,差異有統計學意義[病變支數冠狀動脈單支、雙支、三支病變各亞組(177±41)、(182±32)、(183±35)μg/L和Gensini積分0~19分、20~39分、≥40分各亞組(175±38)、(179±38)、(182±36)μg/L比(160±44)μg/L,均P<0.05],但各亞組間差異無統計學意義(P>0.05)。④血漿Lp-PLA2水平與年齡、體重指數、總膽固醇、三酰甘油、LDL-C、HDL-C、hs-CRP、高血壓病史、糖尿病病史、吸煙史均無明顯相關性。⑤年齡、吸煙史、血漿Lp-PLA2水平是冠心病的獨立危險因素。 LDL-C、hs-CRP、血漿Lp-PLA2與Gensini積分獨立相關。結論血漿Lp-PLA2水平在冠心病患者中明顯升高,是冠心病的獨立危險因素,與冠狀動脈的狹窄程度有一定關繫,但血漿Lp-PLA2水平與動脈粥樣斑塊穩定性的關繫尚需進一步研究。

Objective To discover the relationship between the plasma lipoprotein-associated phospho-lipase A2 (Lp-PLA2) level, the stability of coronary atherosclerotic plaque and degree of coronary atherosclerosis in patients with coronary heart disease (CHD).Methods Two hundred and fifty-four patients who received the coronary angiography ( CAG) in China-Japan Friendship Hospital were selected .According to the CAG results , they were divided into CHD group (n=206) and control group excluded of CHD (n=48).According to the clini -cal types, the CHD group was further divided into subgroups of stable angina pectoris ( SAP), unstable angina pectoris ( UAP) and acute myocardial infarction ( AMI) .According to the number of diseased coronary branches , it was divided into subgroups of lesion in single , double or triple vessels .According to Gensini′score, the group was divided into three subgroups of 0 to 19 scores, 20 to 39 scores and ≥40 scores.Plasma levels of Lp-PLA2 were detected by enzyme-linked immunosorbent assay ( ELISA) .Clinical information and biochemical data such as age, sex, body mass index (BMI), prior medical history including hypertension , diabetes mellitus and smoking status, levels of total cholesterol(TC), triglyceride, low density lipoprotein-cholesterol(LDL-C), high density lip-oprotein-cholesterol ( HDL-C ) and high-sensitivity C-reactive protein ( hs-CRP ) were obtained before CAG . Results ①The level of Lp-PLA2 was significantly higher in CHD group than that in the control group [(180 ± 37)μg/L vs (160 ±44)μg/L, P<0.01].②Compared with the control group , levels of Lp-PLA2 were higher in SAP group, UAP group and AMI group[(183 ±38),(178 ±34),(181 ±38)μg/L vs (160 ±44)μg/L, all P<0.05].There were no significant differences in the levels of Lp-PLA2 between SAP, UAP and AMI group (P>0.05).③In CHD group, the level of Lp-PLA2 increased with the increasing number of diseased coronary bran-ches and Gensini′score[numbers of the pathological subgroups: (177 ±41),(182 ±32),(183 ±35)μg/L and each sub group of gensini integral:( 175 ±38 ) , ( 179 ±38 ) , ( 182 ±36 )μg/L vs ( 160 ±44 )μg/L, all P<0.05].However, there was no significant difference between the subgroups respectively (P>0.05).④Plasma levels of Lp-PLA2 were not related with age , sex, BMI, TC, triglyceride, LDL-C, HDL-C, hs-CRP, prior medi-cal histories including hypertension , diabetes mellitus and smoking status .⑤Age, smoking status and plasma level of Lp-PLA2 were independent risk factors of CHD .The levels of LDL-C, hs-CRP and Lp-PLA2 were related to the Gensini′score independently .Conclusions Plasma level of Lp-PLA2 is significantly high in CHD patients , which is an independent risk factor of CHD .To some extent , it can reflect the degree of stenosis in coronary artery .But the relationship between Lp-PLA2 levels and the stability of coronary atherosclerotic plaque needs further research .
