My father had a massive heart attack in December 2016 & was only expected to live weeks - short months. All active treatment has been withdrawn but 9 months later he is still alive. He has severe heart failure but his only symptoms are extreme fatigue, leaving him bedbound, & some confusion. He is showing no breathlessness or swelling. I am starting to doubt the prognosis & wanted to know if all heart failure patients experience all the usual symptoms of fatigue, breathlessness & swelling? Can anybody enlighten me on what to expect in his final stages?
