Figure 1.
Coronary angiography and CMR images in the presence or absence of microvascular obstruction.
a) Coronary angiography images showing proximal occlusion of the left anterior descending artery, b) CMR demonstrating short axis T2 weighted imaging of myocardium at risk (early CMR), c) short axis late enhancement imaging (early CMR), and d) short axis late enhancement imaging (late CMR), in patients with (MVO +) or without (MVO -) microvascular obstruction. Early CMR was performed 1–4 days after primary PCI and late CMR was performed 4 months later.

Figure 3.
Myocardial salvage in patients with or without microvascular obstruction (MVO).
Myocardial salvage, in patients with (MVO +) or without (MVO−) microvascular obstruction, assessed both by early and late CMR, respectively (percent, median values, and interquartile range).

Patient baseline characteristics according to absence (MVO−) or presence (MVO +) of microvascular obstruction (MVO). Data are presented as median values (interquartile range) or numbers (percentage).
