微量CK-MB对急性心肌梗塞的诊断价值

Significance of minimally elevated creatine kinase-MB in suspected AMI

回顾性分析18090个血清肌酸磷酸激酶(CK)和13689个血清 CK 同功酶(CK—MB)标本的测定结果。发现阳性 CK—MB 伴始终正常 CK 和微量 CK—MB 伴中度升高 CK 通常提示有 AMI 可能;而微量 CK—MB 伴显著升高 CK 或正常 CK 则不常伴有 AMI。

Creatine kinase(CK)and CK isoenzymes were analyzed in 18090 and 13689 sera respectivly.Our data suggest that positive CK-MB with persistently nor- mal total CK activity,and trace CK-MB with moderately elevated total CK activity are generally indicative of an acute myocardial infarction,especially of NQMI and reinfarction,but trace CK-MB with either very high total CK levels or normal total CK activity usually is not related to an acute myocardial infarction.
