Other studies developed similar criteria for new-onset HF with major criteria as no former history of HF with either two of the three findings such as presenting symptoms of congestion, elevated levels of BNP >100 mg/dL, or NT-proBNP >300 mg/dL, and chest x-ray signs of HF or echocardiographic evidence of diastolic or systolic myocardial dysfunction [5]. Here, NPPB is linked to hydrops fetalis.
