【摘要】 冠心病为多基因遗传病,近年来越来越多的临床研究证明炎症反应引起的血管内皮损伤,在冠心病的发生、发展中有着重要作用。临床学者普遍认为除炎性因子外,免疫因子在疾病的发生中亦有重要作用;同时随着生物医学、检验技术的不断发展进步,组织蛋白酶K(Cat-K)、脂蛋白相关磷脂酶A2(LP-PLA2)、缺血修饰白蛋白(IMA)以及和肽素(CPP)等新的生物指标,亦被证实在冠心病的危险程度评估、预后预测中有着重要指导意义。现就Cat-K、LP-PLA2、IMA以及CPP等各生物指标与冠心病的发生、发展关系研究进展做一综述。

【Abstract】 Coronary heart disease is polygenic disease and in recent years,more and more clinical studies have shown that vascular endothelial injury caused by inflammatory reaction plays an important role in the occurrence and development of coronary heart disease.The author through a large number of summary,access to existing literature found that clinical scholars generally believe that in addition to inflammatory factors,the immune system also has an important participation;at the same time,we found that with the progress of biomedicine and testing technology,the expression of Cat-K,LP-PLA2,IMA and copeptin(CPP)And other new biological indicators have also been confirmed in the assessment of the risk of coronary heart disease,prognosis has an important guiding significance.The research progress of the relationship between the development of biological indicators such as Cat-K,LP-PLA2,IMA and CPP and coronary heart disease is reviewed.

中国心血管病流行病学报告数据显示,1990-2010年全球死亡原因中,缺血性心脏病排名第一,而我国20年间冠心病死亡人数增加120.3%,冠心病死亡率占全球的13%,且死亡人数仍然呈增加趋势,因此掌握冠心病发生、发展的危险因素,并采取积极的预防措施,降低冠心病发病及死亡率有着重要临床及社会意义[1]。以往临床多采用白细胞计数、血清淀粉样蛋白酶A、C反应蛋白以及纤维蛋白原等用于预测心血管疾病患者的风险及程度,然而大量研究证实,上述非特异性炎症标志物在预测冠心病风险中效果有限[2-4],在干预、减少心血管事件风险中效果不佳,因此近年来国际学者加强了对新型血管炎症因子的研究,发现Cat-K、LP-PLA2、IMA以及CPP等生物指标与动脉粥样硬化、冠心病的形成及发展关系密切,且其特异性明显高于传统的炎症标志物,现就各指标与冠心病的关系做一综述。……
