尽管肌酸激酶(Creatine Kinase)的活性无特异性,诊断价值较小,但诊断心肌梗塞时,血清肌酸激酶的活性测定还是一种常用的方法。不过,健康人在运动以后,酶的活性还是升高。而测定肌酸激酶MB型同功酶(Creatine Kinase MBisoenzyme)却比较特异和敏感,但剧烈运动后,仍是出现酶活性的升高,使诊断心肌梗塞的可靠性受到一定影响。本文旨在对肌酸激酶肌酸激酶MB Although the activity of creatine kinase is nonspecific and its diagnostic value is small, the determination of serum creatine kinase activity in the diagnosis of myocardial infarction is still a common method. However, healthy people after exercise, enzyme activity or increased. However, Creatine Kinase MBisoenzyme is more specific and sensitive, but after the vigorous exercise, the enzyme activity still appears to increase, which makes the diagnosis of the reliability of myocardial infarction affected to a certain extent. This article aims to creatine kinase creatine kinase MB
