Creatine Phosphokinase Isoenzymes in Head Injury

ABSTRACT

We performed a electrophoresis to determine the serum level of isoenzyme of creatine phosphokinase in 30 patients with head injuries. The present study was undertaken to examine whether the measurement of serum level of brain type isoenzyme(CPK-BB) and heart type isoenzyme(CPKMB) were valuable in evaluating the clinical status of head injuries. All patients were diagnosed by Glasgow coma scale score, CT scan and then we performed a serial blood sampling during the first 7days. Brain type creatine phosphokinase(CPK-BB) was detected in the serum in 4 of 30 patientts(13.3%) and heart type creatine phosphokinase(CPK-MB) was detected in the serum in 8 of 30 patients(26.7%). These findings were seen within 48 hours after head injuries. The higher level were associated with severe brain damage; hemorrhagic contusion, subdural hemorrhage, subarachnoid hemorrhage and pneumocephalus.
