Hi Joanne, I'm very sorry to hear about your Dad
we've been going through similar times here....three weeks days ago my Mom sent me an e mail letting me know the Doc told her and my Dad to prepare his affairs and set up hospice....he was told he'll be gone within 6 months at best. I got his Doctors number and called him. Dads heart at 77 years old is only working at 15% causing all kinds of problems as you can guess. I asked the doc about treatments and he let me know nothing could be done....then I started pushing the doc about heart transplants, valve replacements, heart pumps etc.... The end result....48 hours later my Dad was transferred to Brigham in Boston which is one of the best heart hospitals in the country. They stabilized him, reconfigured his meds, analyzed him for the proper mechanical device and determined he needs a special "turbo" pacemaker which will be installed on Wed this week coming. right now on a scale of 1-10 he's a 7 and his prognosis is good for a long life. The whole experience has been very draining and we empathise with what you've been going through and what you still must go through. Our prayers and thoughts are with you and your family, remember....all of us are here for you.
Condolances from Doug and Sherri
