A Case of Acute Myocardial Infarction Diagnosed by LDH Isoenzyme Analysis

ABSTRACT

Authors experienced a case of acute myocardial infarction confirmed by analysis of LDH isoenzyme. 53-year-old male was admitted to Sacred Heat Hospital, Chung Ang University Because of severe precordial pain radiating to both arm, shoulder and back. Chest X-ray film & electrocardiogram were within normal limit and SGOT was 110 unit/ml on the day of admission. Determination of total LDH value and analysis of LDH isoenzyme by agar gel electrophoresis were made on the second hospital day. Total LDH was 315unit/ml, but there was significant increased percentage of LDH isoenzyme(LDH1). Electrocardiogram showed ST segment elevation only on the 8th hospital day.
