<s>[INST] my mother has stage IV CHF, she experiences shortness of breath, cannot get up a few stairs without rest and often has dizzy spells, when she was in hospital she also suffered from acute kidney failure. She has been advised that she is not a candidate for heart transplant and she was advised here heart is at 10% function. Can you advise what can be done at what is approx life expectancy. [/INST] Hi Charts very unpleasant to hear that, and I completely understand what you are going through. Stage 4 is the last stage of CHF (congestive heart failure) and medicines barely provide any relief to the patient. The only option at this stage is a heart transplant but again unfortunately due to the complexity of the surgery and many other factors very few patients qualify for it.90% of the patients will pass away within one year of stage 4 Heart failure. Just try to keep her happy all the time be with her don't let her feel lonely. May god bless </s>
