The serum BNP level had a negative correlation with EF (r = -0.39, p = 0.008), TAPSE (r = -0.47, p = 0.001) and a positive correlation with E/Em ratio (r = 0.48, p = 0.001), LVEDD (r = 0.15, p = 0.30), and LVESD (r = 0.11, p = 0.47) in patients with severe preeclampsia (Figure 2). Here, NPPB is linked to preeclampsia.
