Hi and thank you so much for this query.
I am so sorry to hear about what your mother is going through. I understand how difficult it is to watch a loved one battle with these disease conditions. Talking about how long she has to live is a difficult topic but also important to be discussed for various reasons.
Considering the information you have provided, mortality is high, ranging from 40% to 95% over a 3- to 6-month period in various series. This means that as few as 5 out of 100 persons with decompensated heart failure
would be alive after 6months.
I hope this addresses your query fully. Thank you so much for patronizing our services and please do feel free to ask for follow up clarifications and information if need be. I wish her the best of health.
Dr. Ditah, MD.
