  1. HOMA, Homeostatic Model Assessment; ECG, electrocardiogram; ST-E, ST segment elevation; CFR, Coronary Flow Reserve; SD, standard deviation; SPECT-MPI, single-photon emission computed tomography myocardial perfusion image; IQR, interquartile range.
  2. aOn the basis of Bonferroni’s correction, a p-value less than 0.025 indicates statistical significance.
