This is a different expert with a different answer.
I am a double board certified US doctor, and one of my certifications is internal medicine.
We are trained specifically in heart failure and end of life care. As I read your question, it is ...how long can one live in this condition.
There is no indication for hospice unless her doctor has determined 6 months or less to live.
That can not be said from the current description.
She might have 1, 3 or 5 years.
This needs to be discussed with her doctor.
This all depends on the actual type of, and stage of her heart failure.
With that information, more accuracy can be given.
Even if the heart failure is "end stage," the one year mortality is 50%.
This means that even some of those with the worst heart failure go on several years or more.
I am sorry about your friend, but the other issue is what type of failure does she have: it might be more right sided.
If it is both sides, that is more serious and might put her in the endstage catetory.
Other questions for her doctors:
Is the afib under control? This can affect the heart failure by 20%
Get her a second opinion as well.
Additional information: It is not clear wht type of facility your friend is in, if she is getting home care, etc. Her degree of energy and activity is a prime factor in her prognosis as well. It also sounds like depression is a possibility, and her primary care doctor and/or cardiologist need to be taking this into account.
An ideal consultation woudl be a geriatric specialist, another type of internal medicine doctor. They will not simply write her off because she is older, or has a serious illness, or needs assistance, but in fact will attempt to optimize here care, medical treatement, mood, and longevity.
