My father has been diagnosed with CHF. He is between 15-20% heart capacity right now. He was recently hospitalized for fluid build up. He is home but the fluid is already starting to build up again. He is mixing up words now. And is on a lot of medication. He is also diagnosed with COPD, and diabetes. I know the prognosis is not good, but wondering what i am looking at here. Most of the pills that he is on affect his other organs. What is the prognosis?
