0引言急性心肌梗死(AMI)是缺血性心脏病的表现形式之一[1].血清肌钙蛋I(cTnI)、肌红蛋白(Mb)和心肌酶是心肌损伤的血清标志物.为了提高对AMI的确诊率,我们对我院近期收治的80例患者的cTnI,Mb和磷酸肌酸激酶(CK),肌酸激酶同工酶(CK-MB),乳酸脱氢酶(LDH),天门冬酸氨基转移酶(AST) 0 Introduction Acute myocardial infarction (AMI) is one of the manifestations of ischemic heart disease.1 Serum cardiac troponin I (cTnI), myoglobin (Mb), and cardiac enzymes are serum markers of myocardial damage To improve the diagnosis rate of AMI, we analyzed the cTnI, Mb and CK, CK-MB, LDH, Aspartate aminotransferase (AST)
