  1. Characteristics related to patient, laboratory data, ECG, and CMR in LGE (n = 8) and non-LGE (n = 12).
  2. Values are reported as the median [interquartile range] or n (%).*statistically significant value (p < 0.05).
  3. CHF indicates congestive heart failure; CMR, cardiac magnetic resonance; ECG, electrocardiography; IQR, interquartile range; LGE, late gadolinium enhancement; LVG, left ventriculogram; LVOT, left ventricular outflow tract; sBP, systolic blood pressure; and TTC, Takotsubo cardiomyopathy.
