Cardiac arrest & resuscitation

Personalized neuron-specific enolase level based on EEG pattern for prediction of poor outcome after cardiac arrest

Ann Intensive CarePublished Retrospective cohort study

Authors' conclusion

In comatose patients after AC, a personalized approach of NSE according to EEG pattern could improve the specificity and sensitivity of this biomarker for poor outcome prediction.

Main finding

As reported in the abstract

NSE threshold predicting poor outcome by EEG pattern
  • Malignant EEG: NSE > 45.2 µg/L, specificity 100%, sensitivity 70.8% (recommended 60 µg/l cut-off: Se = 66%)
  • Electrographic seizures: NSE > 53.5 µg/L, specificity 100%, sensitivity 77.7% (recommended cut-off: Se = 66.6%)
  • Benign EEG: NSE > 78.2 µg/L, Sp = 100% (recommended cut-off: Sp = 94%)

Observational data: associations, not effects.

NSE not significantly increased with seizures vs malignant patterns (p = 0.15)
