The good news is, CHF is treatable, with drug therapy, and
the lasix is a good place to start. Then Coreg, and
, or some other BP med to keep your BP in check.
If you smoke, quit. If you drink alcohol, quit.....and if you have any extra weight, lose it. If you do the medication and all of the above, you should do very well.
I hope the best for you, and that I've answered your questions.
