NPPB and miotic rate: Among patients with a ePASP ˂50 mmHg, those with severe MR exhibited poorer LVEF (35% [IQR = 29%–42%] vs 39% [IQR = 31%–45%], p < 0.001), higher NT-proBNP (logarithmic form: 8.13 [IQR = 7–9] vs 6.84 [IQR = 6–8], p < 0.001) and greater LVEDD (62 [IQR = 59–67] mm vs 60 [IQR = 56–65] mm, p < 0.001) (Fig. 3).
