LV arteries from pair-fed controls on normal (0.6%) NaCl diet (C-NNa; a) and rats with ACRF subjected to 2 weeks of high-NaCl (4%) diet (ACRF-HNa; b, c). In ACRF-HNa rats, arteries from noninjured areas of the myocardium showed modest alterations characterized by thickening of the medial layer (b). In myocardial areas with severe focal tissue injury, arteries (arrow) demonstrated fibrinoid necrosis with destruction of the internal elastic lamina and pronounced occlusion of the vessel lumen (c). Sections were stained with Miller's elastin. ×60.
