血清LD_1同功酶的特异性对心肌梗死的诊断是有价值的。当梗死伴有肝的受累、休克或复苏过程时,释放出其他一些LD同功酶,它使血清LD_1同功酶的百分比值降低,因此用同功酶单位(IU/升)可以作出更好的评价。作者观察了86例经ECG确诊的心肌梗死病人。ECG出现超过0.04秒的QS或Q波,其深度至少相当于R波的1/3,并有ST变化作为心肌梗死的根据。这些病人在住院治疗的头3天进行检查,以确定临床上有无充血性心力衰竭或其他并发症;也测定了
The specificity of serum LD_1 isoenzyme is valuable for the diagnosis of myocardial infarction. When infarction is associated with liver involvement, shock or resuscitation, other LD isozymes are released which decrease the percentage of serum LD 1 isoenzyme and therefore better use of isozyme units (IU / liter) evaluation of. The authors looked at 86 patients with ECG-confirmed myocardial infarction. ECG appears more than 0.04 seconds of QS or Q wave, the depth of at least the equivalent of 1/3 of R wave, and ST changes as a basis for myocardial infarction. These patients were examined during the first 3 days of hospitalization to determine whether there was clinical congestive heart failure or other complications;
