We have read the article published by Loza et al.1 on the prediction of mortality and neurological function in adults recovering from cardiac arrest with great interest. Despite the use of therapeutic hypothermia, patients recovering from out-hospital cardiac arrest are at a high risk of death or severe neurological impairment. The authors described patient age, a non-cardiac origin of cardiac arrest, and a time to return of spontaneous circulation (ROSC) > 20min as predictors of mortality, and found cardiac arrest of cardiac origin, ROSC<20min and defibrillable rhythms to be associated to a favorable neurological outcome. These data coincide with our own recently published findings.2 In fact, most of the variables which we found to be associated to survival free from severe neurological sequelae coincide with those described by Loza et al. (defibrillable rhythm, age and ROSC). In our case we also found lactate concentration upon admission and diabetes to be associated to the patient prognosis; these variables were not described in the study of Loza et al. Lactate upon admission is one of the main prognostic factors following cardiac arrest,3,4 and other authors have also found diabetes to be associated to a lesser probability of ROSC and survival at 30 days.5 We therefore consider it important to include these variables in predictive models of help in predicting survival free from severe neurological sequelae in the follow-up of patients recovering from cardiac arrest.
