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% | |||
