Acute cardiac care & resuscitation

Serum neurofilament light chain and multimodal neuroprognostication after cardiac arrest – A retrospective cohort study

ResuscitationPublished Monocentric retrospective observational study

Authors' conclusion

NFL (SIMOA) > 2000 pg/ml predicts poor neurological outcome with high specificity, while low concentrations strongly argue against severe HIE. Adding NFL to established neuroprognostication tests increases sensitivity of poor outcome prediction.
