Haylie Pomroy interviews Dr. David Systrom about exercise intolerance in ME/CFS and long COVID, discussing the underlying science and ongoing clinical trials.
In today's episode, Haylie Pomroy sits down with Dr. David Systrom, a pulmonary and critical care physician at Mass General Brigham and Assistant Professor at Harvard Medical School, to explore the science behind exercise intolerance in ME/CFS and long COVID.
