急性心肌梗塞一般多以心电图出现ST段改变及异常Q波作为诊断依据。ST段的改变虽很敏感,但特异性不高;而Q 波的特异性虽高,但灵敏度又较差。因此,近年来应用生化方法辅助诊断急性心肌梗塞愈来愈受到重视。本文拟对这方面的进展作一概述。一、胆红蛋白测定由于肌红蛋白分子量小(约17500),旦不易与血浆蛋白相结合,因此极易通过肾小球从尿中排出。正常人尿中的含量不超过5mg/dl。而心肌是肌红蛋白含量最多的组织。所以,如
Acute myocardial infarction is generally more ECG ST segment changes and abnormal Q wave as a diagnostic basis. Although ST-segment changes are sensitive, but the specificity is not high; while the specificity of Q wave is high, but the sensitivity is poor. Therefore, in recent years, the application of biochemical methods to diagnose acute myocardial infarction more and more attention. This article intends to outline the progress in this area. First, the determination of bilirubin Myoglobin due to the small molecular weight (about 17,500), once difficult to combine with plasma proteins, it is easily discharged from the urine through the glomerulus. Urine in normal people does not exceed 5mg / dl. Myocardial myoglobin is the most abundant tissue. So, like
