Macro perspective of congestive heart failure in one rat. A: heart with myocardial infarction (MI). B: atrial thrombus. C: Masson's staining on atrial section. Thrombus is in the left atrium. Blue indicates fibrosis. D: pulmonary edema. Lung became yellow. E: Masson's staining on the lung section. Bronchiole and alveolar wall thickness were increased. Exudation, fibrin, and cellular infiltration were significantly increased compared with lung from control (F). G: interstitial fibrosis in remote area. H: neointima and arterial narrowing in remote myocardium.
