摘要
本文报道42例急性心肌梗塞(AMI)患者血清线粒体天门冬氨酸转氨酶(m-AST)活力的动态变化。多数AMI患者血清m-AST活力在发病后12h明显升高,24h全部升高并达峰值。m-AST诊断AMI的敏感性为100%。特异性为93.5%,与CK-MB相似(P>0.20),可作为AMI诊断的酶学指标。本文未证实m-AST对AMI有预后评估价值。
Serum activities of mitochondrial aspartate aminotransferase (m-AST) in 42 patients of acute myocardial infarction(AMI)were studied to evalute the diagnostic valuo of m-AST for AMI.
The resuhs showed that the activities of m-AST began to increase 12 hours after the onset of chest pain and peaked at 24 hours after the attack. The sensitivity and specificity of m-AST, just like CK-MB (p>0.20), were 100% and 93.5%, respectively. The conclusion is that the dynamic changes of serum m-AST activity is useful for the diagnosis of AMI.
