Hi. My dad is 55 he went in hospital for heart virus that left him with chf his ejection fraction is 10. He was told they want to try medicine of that doesn't work then a difibulator or heart transplant. We're freaking out its not that easy to get a heart there is a very long list. But anyways I'm so worried I hear such good things about coreg. He takes 6.25 2 times a day. It made is bp lower which is around 85/ 65 so he had to stop it if he can't take that certain drug what else is there to help strengthen heart. Please any advice or similar symptoms .
