| 摘要: |
| ［目的］探讨血清肌钙蛋白T（cTnT）和肌酸激酶同工酶（CK-MB）对急性心肌梗死（AMI）的诊断价值。［方法］检测50例因突发胸痛、胸闷及伴有其他临床症状的急诊患者及30例同期非心血管病对照组患者血清肌钙蛋白T和肌酸激酶同工酶的浓度，并进行分析。［结果］患者组与对照组间cTnT、CK-MB值差异均有显著性意义。在检测的50例cTnT升高的患者中，心肌梗死的患者36例，占72%，同期CM-MB阳性率低于cTnT。［结论］cTnT对心肌梗死的诊断有较高的特异性与敏感性，随着发病时间延长CK-MB的敏感性、特异性逐渐升高。 |

| Abstract: |
| ［Objective］To study the value of serum cardiac troponin T (cTnT) and creatine kinase issonzyme MB (CK-MB) in acute myocardial infarction (AMI).［Methods］The concentrations of cTnT and CK-MB in 50 cases of sudden chest pain,emergency patients of other systems and 30 cases of non-heart and vessel diseases were detected.［Results］cTnT and CK-MB had evident difference between patients and control group.AMI patients covered 72% in 50 cases of patients whose cTnT increased.The positivity rate of CK-MB was lower than cTnT.［Conclusions］cTnT has high specificity and sensitivity in the diagnosing AMI. CK-MB's sensitivity and specificity are creasing with the length of time of disease. |
