Hi, My Mother Recently Experienced A Heart Attack Two Weeks

Hi, my mother recently experienced a heart attack two weeks today. She has had a triple by pass 18 years ago and this was all in good order. She had been revived with resuitation twice through this heart attack and CPR twice. We have been told by medical staff that every time is worsening the heart. Her heart is damaged and only working at 20% load. She has been moved into a ccu from icu. However, her body now is leaking fluids and she is placed on a restrictive fluid intact. She has seen elder relatives have this condition prior to passing away. She is becoming anxious, crying and upset which is obviously not good for mental health and heart. I have read on your site by other people's questions and your responses this is not good as other organs failing due to heart not pumping correctly. Can you offer me advise to question her doctors with also medication that could possibly help that I can check she is being given. Basically any suggestions, hope etc
Regards
