My grandpa called the specialist in regards to the congestive heart failure diagnosis and the specialist conveyed to him that he already has been treating him for that. We aren't sure how this diagnosis wasn't relayed to him earlier but are thankful that the specialist already knows what is going on and has already started treatment. 
it's comforting in one sense bc he has been living with CHF for a while and seems to be doing ok. We know that overall outcome of this is not good, but are thankful that God is still touching his body and that gramps is able to still live his life to the fullest thus far. Love, April
