Is fluid balance a cardiovascular problem for a patient with end stage renal disease?

Cardiorenal: Think of a pump (or the heart) building pressure against a filter that is very slow and inefficient, the kidneys in our case. For a while, the pump, which is elastic, will adjust by stretching trying to accommodate the extra load, fluid unfiltered by the kidneys. Once that capacity is reached the heart goes in failure, too. The extra fluid is managed with diuretics and eventually dialysis.
