This video series is intended to review the clinical presentation, scientific underpinnings, and treatment approach for patients with post-exertional malaise (PEM)/post-exertional symptom exacerbation (PESE).
For an abbreviated version highlighting the clinical pearls, please watch videos 1, 2, and 7. Videos 3-6 offer a deeper dive into the scientific and evidence-based pathophysiology of PEM/PESE.
***
Post-exertional malaise (PEM)/post-exertional symptom exacerbation (PESE) is an altered physiological state and pathognomonic finding unique to ME/CFS that is now being recognized in those with post-acute sequelae of COVID-19 (PASC), also known as Long COVID.
It is critical that healthcare professionals recognize PEM/PESE and support the patient in avoiding a push-crash-cycle which can exacerbate disease processes and contribute to worsened long-term functional prognoses.
In video three of this seven-part series Brayden Yellman, MD, and Lucinda Bateman, MD, discuss how Serial 2-Day Cardiopulmonary Exercise Testing (CPET) is a reliable, reproducible and accurate measure of PEM/PESE among those with ME/CFS.
Video details:
- Peak VO2
- Ventilatory Anaerobic Threshold (VAT)
- Impact on ATP production/utilization
- Objective measurements supporting eligibility for disability benefits.
**NOTE: Healthcare providers must weigh the benefits of CPET testing against its potential harms, which could include the induction of a prolonged worsening on an individual’s ME/CFS as a result of the provocation of an extended episode of PEM.**
