Circulation:不同厂家hs-cTnI确诊心肌梗死存在较高不一致性

2015-05-08 MedSci MedSci原创

由于当前监管过程中的局限性,急性心肌梗死(AMI)的误诊可能显著损害患者利益,并可能导致不恰当的心肌肌钙蛋白(cTn)的临床决策值(CDV)。在国际多中心的前瞻性研究中,巴塞尔大学医院心内科的研究人员们在2300例疑似急性心肌梗死患者中使用临床表征和临床使用的高灵敏度cTn检验(雅培hs-cTnI与罗氏的hs-cTnT)来确定AMI诊断不一致的数量。研究人员假设,两个实验的核定CDV不是生物学等价

由于当前监管过程中的局限性,急性心肌梗死(AMI)的误诊可能显著损害患者利益,并可能导致不恰当的心肌肌钙蛋白(cTn)的临床决策值(CDV)。

在国际多中心的前瞻性研究中,巴塞尔大学医院心内科的研究人员们在2300例疑似急性心肌梗死患者中使用临床表征和临床使用的高灵敏度cTn检验(雅培hs-cTnI与罗氏的hs-cTnT)来确定AMI诊断不一致的数量。研究人员假设,两个实验的核定CDV不是生物学等价的,因此可能导致急性心肌梗死诊断的不一致。研究采用特定性别的CDV以及与其他hs-cTnI并行检测的方法,对结果进行了验证。

有473例急性心肌梗死患者(21%)被诊断出来。其中,86例患者(18.2%)使用统一CDV,但是诊断结果不一致。使用特定性别的CDV诊断出的AMI患者中,有14.1%的女性患者和22.7%的男性患者存在诊断结果不一致。使用生物等效CDV使得不一致诊断减少了10%(P<0.001)。同时,这些研究结果用其他HS-cTn检验进行了验证:CDV检测的不一致的发病率仅为7.0%,几乎与生物学等价。

诊断不一致的AMI患者的长期死亡率可与诊断一致的患者相比较(p=ns),并且长期死亡率要比确诊为不稳定型心绞痛(p=0.05)的患者有高的趋势。

目前批准的CDV不是生物学等价的,并且导致急性心肌梗死的诊断有较高比例不一致。如果有替代hs-cTn的方法进行管理,五分之一的急性心肌梗死患者会被确诊为不是AMI。
