My dad is 81 years old and is having CHF. He's also a diabetic and now a stage 3 CKD. He can't get a stent because of bad kidney might resulting in dialysis. His ef is 10-15%. Doctors suggested hospice. With his diagnosis do you think I can nurse him back to health and try to get work done to his heart. I don't want to lug him to doctors appointment if there's no results.
