a-e. Histology of mid-infarct myocardial samples (H&E staining). a Microthrombi material (black arrows) present within the myocardial microvasculature at 3 h post-AMI (original magnification 200×). b Region of AMI showing an artery occluded by thrombus (arrow), at 3d post-AMI (original magnification 400×). c. Infarct junction depicting contraction band change (black arrow) and normal myocardium (yellow arrow) (original magnification 200×). d Extensive recruitment of inflammatory cells within the infarct zone at 3d post-AMI (arrow) (original magnification 25×). e Infarct zone 6 weeks post ischemia shows a subendocardial band of preserved myocytes (black arrow), and a large zone of fibrous tissue (yellow arrow) which has replaced the myocardium, and some residual inflammatory cells (white arrow) (original magnification 25×)
