Newborns are the most vulnerable patients after cardiac surgery. Although mortality risk scores before surgery may help predict the risk of poor outcome, new tools are required, and biomarkers could add objective data to these tools. The aim of this study was to assess the ability of mid-regional pro-adrenomedullin (pro-ADM) and pro-atrial natriuretic peptide (pro-ANP) to predict poor outcome after cardiac surgery. This is a pilot diagnostic accuracy study that includes newborns and infants under 2 months admitted to an intensive care unit after cardiac surgery. Pro-ADM and pro-ANP were determined immediately upon admission. Poor outcome was defined as mortality, cardiac arrest, requiring extracorporeal support, requiring renal replacement therapy, or neurological injury. Forty-four patients were included. Twenty-six (59%) had a STAT category of ≥ 4. Ten patients (22.7%) presented a poor outcome, four of whom (9.1%) died. Pro-ADM was higher in patients with poor outcome (p = 0.024) and death (p = 0.012). Pro-ADM showed the best area under curve (AUC) for predicting poor outcome (0.735) and mortality alone (0.869). A pro-ADM of 2 nmol/L had a Sn of 75% and a Sp of 85% for predicting mortality. Pro-ADM > 2 nmol/L was independently associated with poor outcome (OR 5.8) and mortality (OR 14.1). Although higher pro-ANP values were associated with poor outcomes, no cut-off point were found. The combination of STAT ≥ 4 and the biomarkers did not enhance predictive power for poor outcome or mortality. Conclusion: Pro-ADM and pro-ANP determined immediately after surgery could be helpful for stratifying risk of poor outcome and mortality in newborns.What is Known:• Some congenital heart diseases must be corrected/palliated during the first days of life.A useful tool to predict the risk of severe complications has not been proposed. • Most unstable newborns would have higher values of biomarkers such as pro-ADM and pro-ANP related to shock and compensatory actions.What is New:• Pro-ADM and pro-ANP seem to be good biomarkers to predict poor outcome after cardiac surgery. A pro-ADM < 2 nmol/L would imply a low likelihood of a poor outcome.• Deepening the analysis of biomarkers can help in making decisions to prevent/treat complications.
