Please try not to be scared. Things are seldom as bad as we build them up to be and it won't help your health to be scared but make it worse. First off, you have not been told you are in heart failure from what you said. And even if you are, that is not a death sentence and it need not be chronic. Also, the beta blocker you take "should" keep you from going into heart failure in most cases. But you really need to speak to your doctor and try not to get all worked up in the meantime. I can appreciate how you feel. Trust me. I do. If the first operation did not work, are you sure a second one is a good idea? I don't know. I am just asking. I've not had one and hope I don't have to. But I know lots of people who have and some simply don't take. They may work for awhile and then they don't. Try to pull yourself together. Do you have anyone near you that you can talk to and get some support? Talking to a caring person sometimes works wonders. It sounds like you have done all you can in your present situation. But your doctor is the only one who really knows your situation and knows what would be best for you. So try and talk with him or her as soon as you can. If you can message them, do. If you can contact them on the weekend, do. Do whatever you can to get some answers. Meantime, hopefully someone else will come on here who has more knowledge on this than I do. You'll be ok Jeanette.
