The SFI/NT-proBNP HF score and the MAGGIC score correctly identified 67.6% and 64.4% of the patients who actually died, respectively, while approximately one fifth of the patients surviving one year were predicted to have a 1-year probability of survival < 80% by the SFI/NT-proBNP score compared with one third by the MAGGIC score. This evidence concerns the gene NPPB and hydrops fetalis.
