My Name Is Dennis. I Am A 59 Year Old

My name is Dennis. I am a 59 year old male; 5'!0" and 195 lbs. In Sept. 2010 the wall between the atrium and ventricle tore. I then had a heart attack. Per the cardiologist about 1/3rd of heart muscle is "dead." My ejection fraction is 28%. Prior to the heart issue, I was in good cardiac condition and worked out to maintain muscular flexibility. After 2010 I eventually returned to a routine although much reduced. In December 2014 I was admitted to the hospital for flu-like symptoms. In turns out I did not have the flu. The liver enzymes were "off the chart" and the m.d was operating on assumption I had cirrhosis of liver. I have not yet a biopsy but other diagnostic tests such as ultrasound, CT scan all suggest a normal contour and tone of the liver which is inconsistent with cirrhosis. anyway, I was placed on Lasix because of water retention. since then I have had moderate to severe difficulty breathing, particularly on exertion. I am weak and can no longer work out. I still have edema in ankles, lower legs and stomach. I did not have breathing issues until placed on Lasix. what are your thoughts.
