High magnification micrograph showing<unk>  and karyolysis. H&E stain.<unk>  is a type of uncontrolled cell death<unk>  unique to cardiac myocytes and thought to arise in reperfusion from hypercontraction, which results in sarcolemmal rupture. It is a characteristic histologic finding of a recent myocardial infarction (heart attack) that was partially reperfused. The name of the histopathologic finding comes from the appearance under the microscope;<unk> <unk> s are thick intensely eosinophilic staining<unk> s (typically 4-5 micrometres wide) that span the short axis of the myocyte. They can be thought of extra thick striae, typical of cardiac muscle and striated muscle.
