血清心肌肌钙蛋白I(cTnI)是反映心肌损伤的一种高度特异、敏感的血清标志物,具有很好的临床应用价值。心肌肌钙蛋白是心肌细胞内结构蛋白之一,心肌细胞受损后,细胞内游离的cTnI迅速释放,以后结合的cTnI的逐渐释放入血循环。肌钙蛋白T和I是目前判断微小心肌损伤(MMD)的特异性指?
Serum cardiac troponin I (cTnI) is a highly specific and sensitive serum marker reflecting myocardial injury, which has good clinical value. Cardiac troponin is one of the structural proteins in cardiomyocytes. After the myocardial cells are damaged, intracellular free cTnI is rapidly released, and then the bound cTnI is gradually released into the blood circulation. Troponin T and I are the specific indicators of micro-myocardial damage (MMD).
