Volume change SDI 0.85 9.75% 0.85 0.82
Thickening SDI (>0.5 mm) 0.75 15.8% 0.65 0.79
Radial strain SDI 0.59 22.2% 0.95 0.29
Longitudinal strain SDI 0.59 20.7% 0.83 0.40
Circumferential strain SDI 0.6 8.9% 0.60 0.62
Combined strain SDI 0.58 5.6% 0.80 0.46
  1. Abbreviations: AUC area under the curve, SDI systolic dyssynchrony index.
  2. The area under the curve (AUC) statistic, optimal cut-off values, sensitivities and specificities for each method to predict reverse remodeling (RR) is shown.
