Two years ago I was diagnosed with X-linked myopathy with excessive autophagy. My concern is ensuring that this disease is not going to effect my heart or lungs. There is also no information on how to deal with this disease. I have always been active in sports and weight lifting all my life. Going up stairs and getting out of chairs continues to be more difficult. I read articles about what the problems will be - but I read nothing as to what I can do to make my life and pain more manageable. Has anyone with this condition ever had heart issues?
