[A case of rhabdomyolysis complicated with myocardial injury].
A 22-year-old man developed transient unconsciousness during running. He developed fever, nausea, vomiting, diarrhea and general fatigue. Next day, he was admitted to National Hospital Nayoro because of high serum CK level of 13,610U/l. Biochemical analyses revealed elevated serum myoglobin, increased CK-MM isozyme, aldolase and lactate dehydrogenase, increased serum osmolality, increased uric acid, and decreased serum potassium levels. Therefore, he was diagnosed as having rhabdomyolysis. In addition, serum CK-MB isozyme, cardiac myosin light chain I and troponin T were increased, suggesting the damage of cardiac muscle. Electrocardiogram showed elevated ST segment and inverted T on V2-4, which were not observed previously. He had no preceding infectious disease, drug ingestion or an underlying metabolic disorder. The rhabdomyolysis may be precipitated by the superimposition of dehydration and loss of potassium due to diarrhea and vomiting. The myocardial injury, probably produced by transient myocardial ischemia, should be paid attention in case of rhabdomyolysis.
