ADM and bacterial infectious disease: Our aims in this investigation were to assess in critically-ill patients after CPB: i) PCT, pro-ADM and pro-ANP levels in the first 36 hours post-CPB; ii) the prognostic usefulness of these biomarkers comparing with PRISM III, regarding the need for respiratory and hemodynamic supports, and LOS after CPB and iii) the usefulness of these biomarkers as predictors of bacterial infection.
