Cannot say: without an exam, I can only give general information. and it would depend on the overall labs in the past, use of aspirin like drugs, what other drugs are present (ace inhibitors). BUT
the ratio of bun to creatinine is high. This implies low filtration that is improved with a bit more water in diet.

CHF/ renal disease: This question is best asked to you cardiologist, as you have CHF and kidney damage so your fluid balance is very delicate. Drinking too much can put you back in CHF. Would recheck your creatinine and your creatinine clearence, EF on echocardiogram as it may have changed. Discuss this with your cardiologist
