【摘要】 根据心肌肌钙蛋白Ⅰ(cTnI)与肌红蛋白(Mb)在急性心肌梗死(AMI)发生后的定时定量分析结果比较,为AMI的早期诊断提供更灵敏、更准确的监测指标。本文采集95例AMI患者于胸痛发作0～4h、8h、12h、24h、48h、3天、5天和7天的血清,以及对照组38名的空腹血清同步进行cTnI与Mb的动态检测和比较,结果发现,AMI患者的早期0～4h Mb的灵敏度明显高于cTnI;而8h后cTnI的灵敏度和准确度明显高于Mb。更多还原

【Abstract】 To explore the clinical value of cardiac troponinⅠ(cTnⅠ)and myoglobine(Mb)in the early diagnosis of acute myocardial infraction(AMI),the serum cTn I and Mb were detected in 95 AMI patients at various time phase including 0～4 h,8 h,12 h,24 h,48 h,3 days,5 days and 7 days after they got breast-ach,and 38 healthy controls.The results showed that the sen- sitivity of Mb in the diagnosis of AMI was higher than that of cTnI when the AMI occurred in 0～4 hours.However,the sensitivity and accuracy of cTnI in the diagnosis of AMI were higher than that of Mb in 8 hours later.更多还原
