Park YR, et al. - Authors here looked for the associations between Neutrophil gelatinase-associated lipocalin (NGAL) levels post-cardiac arrest and long-term outcomes and survival. In this study, post-cardiac arrest serum NGAL was associated with long-term outcomes and survival. For predicting long-term outcomes, 3 days post-cardiac arrest was particularly the optimal time point. However, NGAL had an unsatisfactory predictive power and should be regarded as an additional prognostic modality.
