超敏C反应蛋白在冠心病中的表达特性

目的探讨血清超敏C反应蛋白(hsCRP)在冠心病中的表达特性。方法随机选取115例经冠脉造影证实的冠心病患者,包括稳定型心绞痛(SAP)39例,不稳定型心绞痛(UAP)34例,急性心肌梗塞(AMI)42例,50例健康人作为对照组。在OlympusAU2700全自动生化分析仪上应用乳胶增强免疫透射比浊法测定血清中hsCRP的浓度,并分析治疗前后hsCRP水平的差异。结果冠心病患者中hsCRP浓度与对照组相比明显增高,差异具有统计学意义(P<0.01)。AMI组hsCRP水平明显高于UAP组,UAP组hsCRP水平明显高于SAP组,均有统计学意义(P<0.01)。冠心病各组的hsCRP水平在治疗前后比较有统计学意义(P<0.01)。结论冠心病患者血清hsCRP水平显著增高,提示冠心病患者可能存在炎症反应。检测hsCRP对冠心病的辅助诊断、疗效观察及预后判断具有重要价值。

Expression characteristic of serum high-sensitivity C-reactive protein in coronary heart disease

Objective To discuss the expression characteristic of high-sensitivity C-reactive protein(hs-CRP) in coronary heart disease.Methods 115 patients of coronary heart disease confirmed by coronary angiography were randomly recruited, including 42 cases of acute myocardial infarction(AMI),34 cases of unstable angina pectoris(UAP) and 39 cases of stable angina pectoris(SAP). Another 50 patients of healthy persons were recruited as control group. Their levels of serum hs-CRP were determined by particle enhanced immuoturbidimetric method at the analysis instrument of Olympus AU2700.Later the variation of hs-CRP before and after treating was analysed.Results hs-CRP concentration of CHD patients was significantly higher than that of the control group(P<0.01).The levels of hs-CRP of AMI group were significantly higher than those in UAP group.The levels of hs-CRP of UAP group were significantly higher than those in SAP group (P<0.01). There was significant difference in the levels of hs-CRP of every CHD groups before and after treatment(P<0.01).Conclusion The level of serium hs-CRP in CHD is significantly higher than that of the control,which indicates that inflammation may occur in CHD.It is of great value to the diagnosis,treatment and prognosis of CHD.
