目的探讨心肌生化标志物与肌钙蛋白I(cTnI)测定在急性心肌梗死(AMI)早期诊断中的临床应用。方法对128例确诊为急性心肌梗死患者以及70例健康体检者进行心肌生化标志物与肌钙蛋白I的检测分析。结果心肌生化标志物诊断AMI的敏感性为84.4%,特异性为92.9%。心肌肌钙蛋白I(cTnI)诊断AMI的敏感性为97.7%,特异性为95.7%。结论心肌肌钙蛋白I(cTnI)对AMI的早期诊断,更具有临床价值。
Objective To investigate the clinical application of myocardial biochemical markers and troponin I (cTnI) in the early diagnosis of acute myocardial infarction (AMI). Methods The myocardial biochemical markers and troponin I were detected in 128 patients diagnosed as acute myocardial infarction and 70 healthy subjects. Results The myocardial biochemical markers of AMI were 84.4% and 92.9% respectively. The sensitivity and specificity of cardiac troponin I (cTnI) for the diagnosis of AMI was 97.7% and 95.7% respectively. Conclusions Cardiac troponin I (cTnI) is of clinical value in the early diagnosis of AMI.
