David Systrom, a Harvard pulmonologist, uses invasive CPET tests to find that oxygen extraction problems at the muscle level are common in ME/CFS.
Chronic fatigue syndrome (ME/CFS) has a reputation for falling through the cracks. Test after test is run to no avail. From the unusually devastating effects on functionality to the fact that exercise makes people worse rather than better, ME/CFS has been a disease that defies medical dogma.
Workwell’s two-day exercise test results, for instance, have run up against the dogma in exercise physiology that even if you have serious diseases like heart disease or kidney failure, exertion just doesn’t reduce your ability to produce energy. Something, exercise physiologists have even asserted, must be wrong with Workwell’s machine to produce that kind of result in ME/CFS. (Workwell’s findings have been replicated by other researchers.)
The first sentence in the abstract of David Systrom’s new study sums up our dilemma perfectly:
“The clinical investigation of exertional intolerance generally focuses on cardiopulmonary diseases, while peripheral factors are often overlooked.”
