New Abstract on invasive CPET – Promising outcomes
The American Journal of Respiratory and Critical Care Medicine has posted a new abstract authored by David Systrom et al, which evaluated invasive CPET testing. The test includes iCPET results from 438 ME/CFS patients, 73 Long Covid patients, and 43 symptomatic but otherwise normal controls.
The measurement method is illustrated here from their previous 2023 report [TBA]
