What Is The Life Expectancy When Diagnosed With 20% Ejection Fraction?

I recently had a ejection fraction of 20% 7 weeks ago. I am sick with a lot of stomach problems when I eat my stomach is in pain or I throw up I get nauseated throughout the day I have lost 40 lbs in 6 months not because I wanted but because I go through periods of times where I just throw up and throw up for days on end . Other days I m just very nauseated I have swelling in my ankles feet and hands I wake up like that and it stays for days I get tingles in my ankles when I get swollen I stay swollen it goes down very kittle. I am dizzy almost everyday when sitting but mostly upon standing and walking around i start to feel faint as well .
