Yes, I am not, but there are many people that have HF without
HA. There are many medical conditions that produce it.
Going back to normal life it depends very much of what is the reason of your HF and your personal circumstances (age, sex, race (yes black skin is bad for HF))...
However, if go get a good cardiologist specialized in HF, and follow strictly his indications, you can have many years ahead.
