Figure 1. Reverse remodelling (≥ 15% reduction in baseline LVESV at 6-months follow-up) according to LBBB morphology and to QRS duration.
Figure 2. Discrimination of all-cause death, hospitalizations for heart failure and combined event according to QRS duration and to each LBBB classification.
Harrell’s c values are reported on the x-axis, endpoints on the Y-axis. Bars, representing the Harrell’s c for each LBBB classification are ranked according to the value of the Harrell’s c for the combined endpoint.
