- 3 years old cow. In our region, diseases more likely to be listed as cause are hardware disease (1.8% of our diagnosis), endocarditis (2.7%) and Ateleia glazioviana poisoning (0.5%). The combination of compensatory mechanisms, brought into play to maintain cardiac output, is in general successful. However, there is also the planting of the seeds of destruction. Both the local increase in venous hydrostatic pressure and the increased sodium and water retention by the kidneys tend to promote the development of interstitial edema. Depending on the inciting abnormality, it is usual for one side of the heart to fail before the other, but it must be remembered that the cardiovascular system is a closed circuit and that failure of one side will eventually embarrass the other. There is some species difference in the distribution of edema in congestive heart failure. In ruminants and horses, dependent subcutaneous edema is expected; in the other species, excess subcutaneous fluid is scant or absent. Reference: Jubb et al., Pathology of Domestic Animals.
