  1. Bold values indicate significant p value (p ≤ 0.05)
  2. HF heart failure, LVEF left ventricular ejection fraction, LVEDV left ventricular end-diastolic volume, LV left ventricular, NYHA New York Heart Association, LGE late gadolinium enhancement, ECV extracellular volume fraction
  3. *P ≤ 0.05 is considered significant
  4. aFor each outcome, the Youden index was used to depict optimal cutoff values from the ROC curves (see Table 2)
