Independent risk factors associated with outcomes were ischemic etiology of HF [HR 1.731 (1.227–2.441), p = 0.0018], mean arterial pressure (MAP) [1.026 (1.010–1.042), p = 0.0011], body mass index (BMI) [1.055 (1.014–1.098), p = 0.0083], sodium [1.056 [(1.007–1.109), p = 0.0244] PTX-3 [1.187 (1.126–1.251, p < 0.0001) and N-terminal pro-brain natriuretic peptide (NT-proBNP) [HR 1.004 (1.000–1.008), p = 0.0259]. This evidence concerns the gene PTX3 and hydrops fetalis.
