摘要
目的 :探讨心肌肌钙蛋白I(cTnI)在急性心肌梗塞(AMI)时的检测意义 ;方法 :通过比较102例冠心病患者和30例对照的cTnI和心肌酶谱的测定结果 ;结果 :AMI患者的阳性率分别为 :cTnI-87 5 %、CK -MB -62 5%、CK -56 3%、AST-46 9 %、LDH -40 6% ;结论 :AMI患者胸痛后10h血清cTnI的敏感性最高 ,血清cTnI对AMI诊断的特异性明显高于心肌酶谱(CK、CK -MB、AST和LDH) ,对诊断AMI有重大临床价值。
objective:To study the significance of cardiac troponin l(cTnl)in acute myocardial infarction (AMI).Methods:To compare with the results of cTnl and enzymes of 102 cases of coronary heart disease and 30 controls.Results:The positive rates of cTnl,CK-MB,CK,AST and LDH in AMI patients were 87.5%,62.5%,56.3%,46.9%and 40.6%respectively.Conclusions:The highest sensitivity of serum cTnl was within 10 hours after the onset of chest pain in AMI patients.The specificity of serum cTnl was distinct higher than that of CK-MB,CK,AST and LDH.The serum cTnl is valuable for diagnnosis of AMI.
