Figure 2 3 Different Zones on LGE CMR Images of Infarcts
Three different zones—microvascular obstruction (MVO) zone (red arrows), necrotic core zone (green arrows), and total LGE zone (purple arrows)—on LGE CMR images of infarcts are shown. Image is from 5 days after myocardial infarction. This image is for representational purposes only, as not all patient images look the same. LV = left ventricle; other abbreviations as in Figure 1.

Figure 3 Trial Profile
*Number of patients for whom infarct sizes as measured by cardiac magnetic resonance imaging (CMR) are available; the number of patients for whom other results are available may differ. ECG = electrocardiogram; MI = myocardial infarction.

Figure 4 Reduction of Mass of Infarct Size, Necrotic Core, and Total LGE Zones
The mass of affected tissue and median values with 25th and 75th percentile range, 5 days after myocardial infarction, is shown. *Wilcoxon rank sum test. LGE = late gadolinium enhanced.

Figure 5 Reduction of Necrotic Core and Total LGE Zone Size as % of LV
Percent of left ventricle (LV) and median values with 25th and 75th percentile ranges 5 days after myocardial infarction is shown. *Wilcoxon rank sum test. LGE = late gadolinium enhanced.
