I read an article involving Dr. Cheney about Heart Mulfunction and its role in CFS. It can be accessed from this site... titled The Heart of the Matter: CFS & Cardiac Issues and written by Carol Sieverling (Apr 05). I found it most interesting. I had not considered the role of the heart as much until I read this article. It made me consider that an approach addressing issues with mitochondria should take precedent over viral/bacterial/fungus interventions. Any thoughts on this? Dr. Myhill also has an article that speaks to a similar idea titled, CFS is Heart Failure Secondary to Mitochondrial Malfunction.
