应用放射免疫(RIA)测定分析血清肌红蛋白(Mb)浓度,早期诊断心肌梗塞(AMI)。结果表明AMI早期血清Mb浓度超过正常水平的4.7倍;在其他血清酶升高前一天,就可观察到69.9％的AMI忠者血清Mb浓度升高。血清Mb浓度的峰值与心肌损伤范围的大小,严重痖状的有无以及预后的好坏有直接关系,与心电图ST段抬高的幅度呈正相关。
Serum myoglobin (Mb) was analyzed by radioimmunoassay (RIA), and myocardial infarction (AMI) was diagnosed early. The results showed that the serum Mb concentration at the early stage of AMI was 4.7 times more than the normal level; 69.9% of the AMI loyal persons had elevated serum Mb concentrations the day before the other serum enzymes were elevated. The peak value of serum Mb concentration is directly related to the extent of myocardial injury, the presence or absence of severe pterygium, and the prognosis, which is positively correlated with the amplitude of ST segment elevation in ECG.
