血清肌钙蛋白I与心肌酶谱对急性心肌梗死诊断价值的对比分析

Comparative analysis of serum troponin I and myocardial enzymes in the diagnosis of acute myocardial infarction value

目的对比在急性心肌梗死患者中cTnI(心肌肌钙蛋白I)与心肌酶谱的诊断价值。方法用Lχ20全自动生化分析仪测定40例急性心肌梗死患者和35例正常对照组的心肌酶谱,同时用微粒子酶免疫法测定相应的cTnI含量,对比分析cTnI和心肌酶谱的诊断价值。结果急性心肌梗死患者组心肌酶谱阳性率分别为LDH87.5%、CK-MB70%、CK72.5%,cTnI阳性率为100%。结论在急性心肌梗死诊断中心肌酶谱测定虽具有良好的诊断价值,但没有血清cTnI特异、敏感。

Objective To compare the diagnostic value of cTnI （cardiac troponin I）and myocardial enzymes in patients with acute myocardial infarction. Methods Myocardial enzymes in 40 patients with acute myocardial infarction and 35 cases of normal control group：Lχ20 automatic biochemical analyzer measurement of cTnI levels measured using microparticle enzyme immunoassay, comparative analysis of the diagnostic value of cTnI and myocardial enzymes. Results Acute myocardial infarction group the myocardial enzymes-positive rate were LDH87.5 %, CK-MB, 70 %, CK 72.5 % the cTnI positive rate of 100%. Conclusion The determination have good diagnostic value in the diagnosis of acute myocardial infarction myocardial enzymes, but there is no the serum cTnI specific, sensitive.
