摘    要:目的 探讨血清超敏C反应蛋白(hs-CRP)、胱抑素(Cys-C)表达水平对急性冠脉综合征(ACS)的临床诊断价值.方法 选取入住我院心内科134例ACS患者,其中稳定型心绞痛患者(SA)60例,不稳定型心绞痛患者(UAP)52例,急性心肌梗死(AMI)患者22例,同时健康体检者62例,测定各组hs-CRP、Cys-C l以及相关性因子的水平,并进行统计学分析.结果 ①ACS患者hs-CRP(mg/L)(SA组:4.87 ±0.65、UAP组:9.81 ±1.13、AMI组:20.27±2.36、对照组1.24±0.52)、Cys-C (mg/L)(SA组:0.76±0.13、UAP组:1.03±0.17、AMI组:1.39±0.36、对照组0.46±0.07、基质金属蛋白酶(MMP)-9(μg/mL)(SA组:308.43±35.52、UAP组:379.86±27.90、AMI组:420.13±50.16、对照组112.07±10.18)以及IL-6 (pg/L)(SA组:62.37±5.18、UAP组:69.05±7.18、AMI组:72.53±6.95、对照组27.19±3.96)表达水平明显升高,差异具有统计学意义(P<0.05),内皮细胞一氧化氮合酶(eNOS)(μmol/L)(SA组:22.84±2.65、UAP组:19.43±1.79、AMI组:7.93±1.17、对照组30.19±3.53)水平相对于对照组降低,差异有统计学意义(P<0.05);②ACS血清hs-CRP表达与Cys-C,MMP-9,eNOS相关(P<0.05),Cys-C与MMP-9、eNOS、IL-6表达具有相关性(P<0.05);③SA组、UAP组以及AMI组血清hs-CRP、Cys-C表达水平依次升高,差异具有统计学意义(P<0.05).结论 血清hs-CRP、Cys-C表达对于诊断ACS可能具有临床意义.

Abstract:Objective To investigate the clinical diagnostic value of serum high sensitivity C-reactive protein (hs-CRP) and cystatin (Cystatin,Cys-C) expression levels in acute coronary syndrome (ACS).Methods We measured and analyzed the expression level of Hs-CRP,Cys-C,MMP-9,IL-6 and eNOS in 134 patients with ACS and 62 healthy people.ACS patients contain 60 stable angina (SA) patients,52 unstable angina pectoris (UAP) patients and 52 acute myocardial infarction (AMI) patients.Results ① The expression level of hs-CRP (mg/L) was higher in SA group(4.87 ± 0.65),UAP group(9.81 ± 1.13) and AMI group (20.27 ± 2.36) compared with healthy group (1.24 ± 0.52) (P < 0.05).The expression level of CysC (mg/L) was higher inSAgroup(0.76 ± 0.13),UAPgroup (1.03 ± 0.17) and AMI group (1.39 ±0.36) compared with healthy group 0.46 ± 0.07)(P < 0.05).The expression level of M MP-9 (μg/mL) was higher in SA group (308.43 ± 35.52),UAP group (379.86 ± 27.90),AMI group (420.13 ± 50.16) compared with healthy group(112.07 ± 10.18) (P < 0.05).The expression level of IL-6 (pg / L) was also higher in SA group (62.37 ± 5.18),UAP group (69.05 ± 7.18),AMI group (72.53 ± 6.95) compared with healthy group (27.19 ± 3.96) (P < 0.05).However,the expression level of eNOS (μmol / L) was lower in SA group (22.84 ± 2.65),UAP group (19.43 ± 1.79) and AMI group (7.93 ± 1.17) compared with healthy group (30.19 ± 3.53) (P < 0.05) ; ② There are associations between hs-CRP with Cys-C,MMP-9,eNOS and between Cys-C with MMP-9,eNOS,IL-6 (P < 0.05) ; ③The expression of hs-CRP,Cys-C in SA group,UAP group and AMI group increased gradually,which has a statistically significant difference (P <0.05).Conclusion Expression of serum hs-CRP and Cys-C has clinical significance for the diagnosis of ACS.
