Figure 1 Representative trichrome images from pigs with hibernating myocardium. Images from representative animals studied three, four or five months after instrumentation were stained with Masson’s trichrome to facilitate quantification of connective tissue (blue). The left anterior descending coronary artery regions (upper row) illustrate the generalized and diffuse connective tissue staining pattern that was present in hibernating myocardium. Total connective tissue staining was slightly higher in hibernating myocardium as compared with the normally perfused region of the same animal (lower row). Magnification 600x.
