Table 2 CMR MO and LV remodeling in patients

From: CMR of microvascular obstruction and hemorrhage in myocardial infarction

Study Method of MO assessment (yes/no for all) Imaging time post-MI Prevalence of MO Findings
Positive studies
Wu et al.[43] N = 44 · Early · 10 days 25% Early MO predicted LV remodeling
· 16 months
Hombach et al.[20] N = 110 · LGE · 6 days 46% Late MO, infarct size predicted LV remodeling
· 7.5 months
Nijveldt et al.[49] N = 60 · First-pass · 2-9 days · 68% (FP Late MO was the strongest predictor of LV remodeling
· LGE · 4 months · 57% (LGE)
Orn et al.[30] N = 42 · First-pass · 2 days Day 2: Late MO was associated with the worst LV remodeling indices at all timepoints
· LGE · 1 week · 38% (FP)
· 2 months · 33% (LGE)
· 1 year
· 1 week:
· 34% (FP)  
· 21% (LGE)
Weir et al.[50] N = 100 (LVEF < 40%) · Early · 4 days · 69% (Early) Late MO was associated with the greatest change in LV remodeling indices
· LGE · 24 weeks
· 56% (LGE)
Negative studies
Mather et al.[33] N = 48 · LGE · 2 days Day 2 & 1 week 1 week infarct size & LVEF best predicted 3 month infarct size & LVEF
   · 1 week · 60%  
   · 1 month   
   ·3 months
