NPPB and hydrops fetalis: It is interesting to note that the patient had a BNP in the normal range but slightly increased as compared to the value on admission in at the time of discharge when her symptoms and radiologic findings improved (Table 1), likely related to the patient's clinical dynamics of heart failure (HF) management such as due to the mobilization of third-space fluids. Moreover, fluctuations in BNP levels can also be influenced by non-cardiac factors such as renal issues, age, and other comorbid conditions [1].
