Keyword:  冠状动脉疾病心型脂肪酸结合蛋白急性心肌梗死不稳定心绞痛生化标志物;
Abstract: 目的:探讨心型脂肪酸结合蛋白(heart-type fatty acid-binding protein,H-FABP)与近期发作急性冠脉综合征(ACS)的患者冠脉病变严重程度的相关性及原因.方法:ACS患者于发作12 h内入院,1周内行冠脉造影者98例入选,其中急性心肌梗死21例、不稳定性心绞痛77例.采用双抗体两步夹心ELISA法定量测量待测血清H-FABP;根据美国心脏病协会所规定的冠脉血管图像记分分段评价标准,对病变狭窄程度进行分度、累及血管支数计算,采用Gensini积分系统,对冠脉血管病变狭窄程度、病变部位、范围进行定量评定;用H检验分析H-FABP是否大于8.0 ng/mL与Gensini积分的相关性,卡方检验分析血H-FABP与狭窄程度、病变支数的相关性,采用一元回归分析方法分析血清H-FABP与患者冠脉病变严重程度的相关程度.结果:H-FABP>8.0 ng/mL组与H-FABP<8.0 ng/mL组冠脉狭窄程度、累及支数及Gensini积分有明显差异(P<O.001);血清H-FABP与患者冠脉病变严重程度的一元回归分析结果,标准回归系数为0.658,P<0.001;一元线性回归方程,y=13.177+3.597x(y为Gensini积分,x为血中H-FABP浓度).结论:H-FABP与近期发作ACS的患者冠脉病变严重程度呈正相关.血清H-FABP升高是冠脉病变急性加重的直接结果,临床可根据血清H-FABP升高推断冠脉病变的危险度并采取积极的治疗措施.
