  1. Note. - Data are expressed as Mean ± SD. EF=ejection fraction; EDV=end-diastolic volume; ESV=end-systolic volume; ∆LVEF indicates absolute change from baseline to follow-up while ∆LVED(S)V indicates absolute change (mL) and relative change (%).
  2. *p<0.05 for comparison between baseline and follow-up in two groups.
  3. §p<0.05, #p<0.05 for comparison of baseline and follow-up data between patients with and without MVO, respectively.
  4. †p<0.05 for comparison of changes in two groups.
