ECG与心肌肌钙蛋白T在AMI诊断中的价值比较

目的　探讨心电图 (ECG)和心肌肌钙蛋白T(cTNT)在急性心肌梗死 (AMI)诊断中的价值。方法　选择 10 8例胸痛发作 3h内入院的AMI患者 ,并经ECG和cTNT双重连续性监测 ,对比AMI患者ECG特征性改变和相应时间里cTNT的变化。结果　 3h内ECG巨大高耸T占 5 6 %、cTNT升高超出正常者 5 4 % ,2 4hECG出现病理性Q波 78%、cT NT明显升高者 10 0 % ,72h心电图ST段稳定下降者 6 5 %、cTNT均保持较高水平的升高。结论　cTNT对AMI的特异性、敏感性优于ECG ,且诊断时间窗宽 ,但对确立梗死的部位和显示梗死是否穿壁不如ECG

ECG and cardic muscle myo-calcium protein T compares in the AMI diagnosis value

Objective Goal The discussion electrocardiogram(ECG) and cardic muscle myo calcium protein T(cTNT) (AMI) diagnoses at the acute cardiac arrest the value.Methods Chooses 108 examples chest pain to manifest suddenly the ATM patient which in 3 hours is hospitalized, and after ECG and the CTNT dual continuity monitor, contrasts AMI in the patient ECG characteristic change and the corresponding time the cTNT change.Results In 3 hours ECG greatly stands tall and erect T 5 6%, CTNT elevates surpasses the normalcy 54%, 24 hour ECG appears the pathological Q wave 78%, CTNT obviously elevating 100%, 72 hours electrocardiograms ST section stable drop 65%, CTNT maintains compares the high level.Conclusion CTNT to the AMI specificity, the sensitivity surpasses ECG, moreover the diagnosis time window is wide, but to establishes the stem dead spot and the demonstration stem dies whether puts on the wall to be inferior to ECG.
