hi there, I have a question regarding CHF, if it went undiagnosed for 2 months at the minimum, would it affect my heart permanently. I had a Echo EF was 20 %, and hypokinesis global at about 2 all areas. I have been on medication for 5 months, and my EF went up to 45 %, will my heart still be affected, as ie Starlings law of strtech.
