I have had ME/CFS since 1994. I just learned recently that I am now headed into a form of congestive heart failure. From some of the docs' posts it appears that mitochondrial dysfunction may be at the base of the heart issue as well a few other bugaboos. So if the retrovirus is indeed a culprit and can be eliminated, what about the damage already done? What will the prognosis be for those of us who have had this for umpteen years and now find ourselves facing a shortened life span?
