Hello. My mother has chf, copd, aorta aneurysm , and last a fib was in May 14 which renal failure began and the numbers rose to 5.8 then returned to normal with treatment of fluids. No dialysis. She became hoarse afterwards. I understand how her heart disease and meds (One is advair) can cause the hoarseness. Mom s hoarseness has worsened in the past few days. (She has seen the doctor recently and I am a part of every visit and consultation as she lives with me and my family. She has decided no further treatment other than for comfort.). I am curious and do not wish to ask the doctor in front of her, could the changed in the hoarseness ( voice is notably weaker and more raspy), be due to her disease advancing? Does heart disease work that way? Thank you for your time. P.S. She is not on oxygen.
