心肌酶升高是儿童心肌炎诊断的重要依据之一,但并非心肌酶谱中任何一项升高都支持心肌炎诊断。心肌酶谱中最有诊断价值的一项是肌酸激酶同工酶,即CK-MB,因为它主要来自于损伤的心肌细胞,具有心肌特异性。心肌损伤时,同时释放其他多种酶,包括LDH、HBDH、CK,因此,如果只有CK-MB升高而不伴其他酶的升高,不一定有心肌损伤和心肌炎。反之,只有其他酶的升高,而CK-MB正常就更不支持心肌 Increased myocardial enzymes is an important basis for the diagnosis of children with myocarditis, but not in any one of the myocardial enzymes to support the diagnosis of myocarditis. One of the most diagnostic values ​​in myocardial enzymes is the creatine kinase isoenzyme, CK-MB, because it is mainly from injured cardiomyocytes and is myocardial specific. Myocardial injury, while releasing a variety of other enzymes, including LDH, HBDH, CK, therefore, if only CK-MB increased without the rise of other enzymes, not necessarily myocardial damage and myocarditis. On the contrary, only other enzymes increased, and CK-MB even more normal does not support the myocardium
