测定血清肌酸磷酸转移酶(CK)、谷草转氨酶(GOT)、天门冬氨酸转移酶和乳酸脱氢酶(L-DH)是诊断急性心肌梗塞的一个重要方法.当心肌受损时可明显升高.但这些酶也同时存在于其他组织器管中,故特异性不高.而肌钙蛋白-1具有心脏特异性细胞标志的性质,用放射免疫测定肌钙蛋白-1,对急性心肌梗塞的诊断具有重要意义.肌钙蛋白分为肌钙蛋白-1,肌钙蛋白-T 和肌钙蛋白-C.而肌钙蛋白-1是唯一存在于心肌的一种收缩蛋白.当心肌梗塞几小时后从坏死的心肌释放入血
Determination of serum creatine phosphokinase (CK), aspartate aminotransferase (GOT), aspartate aminotransferase and lactate dehydrogenase (L-DH) is an important method of diagnosis of acute myocardial infarction.When the myocardial damage can be obvious However, these enzymes also exist in other organizer tubes, so the specificity is not high, while troponin-1 has the property of heart-specific cell markers, using radioimmunoassay of troponin-1, acute myocardial The diagnosis of infarction is of great importance.Troponins are classified into troponin-1, troponin-T and troponin-C, and troponin-1 is the only contractile protein present in the myocardium.When myocardial infarction A few hours later, blood was released from the necrotic myocardium
