BackgroundMyoclonic status may be observed following cardiac arrest and has previously been identified as a poor prognostic indicator in regard to return of neurologic function. We describe a unique situation in post-cardiac arrest patients with myoclonic status and hypothesize possible predictors of a good neurologic outcome.MethodsCase series.ResultsWe illustrate two cases of cardiac arrest due to a respiratory cause in young patients with evidence of illicit drug use at the time of hospital admission that suffered post-ischemic myoclonic status. These patients subsequently recovered with good neurologic outcomes.ConclusionsOn rare occasions, myoclonic status does not imply a poor functional outcome following cardiac arrest. Other clinical and demographic characteristics including young age, presence of illicit substances, and primary respiratory causes of arrest may contribute to a severe clinical presentation, with a subsequent good neurologic outcome in a small subset of patients.
