【摘要】 目的与方法 :用琼脂凝胶电泳法测定乳酸脱氢酶 ( LDH)同工酶 L D1/ L D2比值。结果 :表明 ,急性心肌梗塞 ( AMI)组 4 4例平均 1.0 4 64± 0 .2 94 7,非心肌梗塞组 35例平均 0 .7690± 0 .1333,二者比较差异显著。首次血清的敏感性为 4 7.7% ( 2 1/ 4 4 ) ,特异性为 97.1% ( 34 / 35)。并与发病后不同本文亦表明LDH同工酶的测定可弥补心电图对AMI诊断上的不足更多还原

【Abstract】 Objective and \method:To detect LDH is oenzyme (LD1/LD2 ratio). Result:The average is 1.0464±0.2947 in AMI group (44 cases). while ,the non infarct group (35 cases) is 0.7690±0.1333.Theres significant diffference.The sensitivity is 47.7% (21/44) specificity is 97.1% (34/35) in the first serum and then compared the LDH、CK-MB、 GOT after infarct in different time ,in order to research the diagnosis value to AMI.Conclusion:Its suggest that the detection of LDH isoenzyme can help the diagnosis of AMI.更多还原
