In two patients, markedly elevated serum BNP levels and significant left ventricular dysfunction was found, which was not apparent by standard clinical evaluation.13 In patients with severe pregnancy-induced hypertension, an eight-fold increase in BNP levels has been documented, with a positive correlation between the plasma BNP levels and the mean arterial blood pressure (r = 0.62, p < 0.001).18 Here, NPPB is linked to hypertension, pregnancy-induced.
