Of note, CA-related HF patients were in rather advanced disease stages when compared to controls, as documented by higher N-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels (median NT-proBNP in pg/mL: 3132.5 [1343.8, 6994.2] in CA patients versus 680.0 [226.1, 1621.0] in controls, p < 0.001)). Here, NPPB is linked to hydrops fetalis.
