My Burt was diagnosed with CHF and an enlarged heart when he was twelve. He managed very well on Lasix until the age of 16. I was always afraid of blood clots and when he got better, decreased his lasix to once a day after talking with the vet. Hids symptoms were decreased activity and a cough. I think a combination of drugs might be better. I gave him his meds by 'pasting' them to a small piece of bacon with a tiny piece of Pill Pocket for cats. He never tired of bacon.
All you can do at this point is to trust your vet's advise. Just love him all you can and keep a quiet environment for him. For him, his beloved home and your love is all he needs.......
