Figure 2 Histologic sections stained with phosphotungstic acid/hematoxylin. (A) Image comparable to the electron micrograph in Figure 1 and demonstrating light microscopic appearance of loss of myocyte contractile apparatus (contractile proteins stain dark purple; most cells demonstrate cytoplasm devoid of protein [c]). (B) Nonrecovering (infarcted) segment again showing abnormal myocytes but with a high fibrous tissue content (f). (C) Hibernating tissue again showing a high proportion of myocytes depleted in contractile protein, but with relatively low volume fraction of fibrous tissue compared to B.
