肌红蛋白测定对早期心肌损伤的诊断价值

目的 观察急性心肌梗死(AMI)患者血清中肌红蛋白(Mb)及心肌酶谱浓度、异常阳性检出率,探讨Mb在AMI早期诊断中的价值.方法 动态检测45例AMI患者血清中Mb和及心肌酶谱浓度,并与23例非AMI胸痛患者比较.结果 45例AMI患者血中Mb峰值在4~8 h出现,浓度达(796±364)μg/L,且发病12 h内异常...

Determination of Myoglobin in the Early Diagnosis of Myocardial Injury

Objective To observe the acute myocardial infarction(AMI) patients with serum myoglobin(Mb) and myocardial enzyme levels,abnormal positive detection rate of Mb in the value of early diagnosis of AMI.Methods Dynamic detection of 45 cases of AMI patients and myocardial enzymes in serum Mb and concentration,and with 23 more cases of non-AMI chest pain patients.Results 45 patients with AMI were peak serum Mb appeared in 4~8 h,the concentration of(796±364)μg/L,and within 12 h of onset of abnormal positive detection rate of 90%.CK and CK-MB peak at about 24 h,last 2~3 d.23 cases of control group patients Mb did not change significantly.Conclusion Mb in AMI appeared early,the concentration of up to several times the normal value not only be used as an important indicator of early diagnosis of AMI,but also its dynamic monitoring of the disease and efficacy of AMI as an important basis.
