Fig 1.
Out of 470 patients, 312 patients who did not meet inclusion criteria, 8 patients who had inappropriate images and 2 patients who were lost to follow-up were excluded, resulting in a final cohort of 148 patients.
Fig 2.
(1) Cardiac magnetic resonance (CMR) images in midventricular short axis views did not show late gadolinium enhancement (LGE). (2) LGE demonstrated a near-circumferential pattern of midwall LGE (white arrows) in the anterior, septal, inferior, and inferolateral segments at midventricular short axis.

Patients characteristics.
Fig 3.
Comparison of cardiac 123I-MIBG scintigraphic findings between the presence or absence of LGE.
The delayed H/M (a) and WR (b) were not significantly different between the presence and absence of LGE.
Fig 4.
Kaplan-Meier analysis according to LGE on CMR and WR by 123I-MIBG scintigraphy.
(A) DCM patients with WR ≥ 45% (red line) had a worse outcome than those with WR<45% (green line). (B) DCM patients with LGE positive (red line) had a worse outcome than those with LGE negative (green line).
Fig 5.
Kaplan-Meier analysis of the combination with LGE on CMR and WR by 123I-MIBG scintigraphy.
The WR ≥45%+LGE positive group had the worst prognosis. Of note, the event rate in the WR<45% + LGE positive and WR ≥45%+LGE negative groups were intermediate (p = 0.89).
