NPPB and atrial fibrillation: About VT events, they are predicted also by LVEF (HR 1.160 [1.012–1.290] CI 95%, p value 0.047), and by QRS duration (HR 1.511 [1.160–1.959] CI 95%, p value 0.026) (Table 4) Similarly, LVEF (HR 1.593 [1.122–1.986] CI 95%, p value 0.006), BNP (HR 1.101 [1.001–1.210] CI 95%, p value 0.017), and QRS duration (HR 1.182 [1.012–1.552] CI 95%, p value 0.043) may predict AF events at 12 months of follow up (Table 4).
