Prognostic performance was compared with N-terminal pro-brain natriuretic peptide (NT-proBNP) and established risk scores (ADHERE, GWTG-HF, OPTIMIZE-HF) using receiver operating characteristics curves, the continuous net reclassification index (cNRI) and decision curve analysis.<h4>Results</h4>Serum MDA, catalase, and SOD were significantly elevated in non-survivors at all time points. The gene discussed is SOD1; the disease is hydrops fetalis.
