    Systemic Vascular Distensibility relates to exercise capacity in connective tissue disease (Singh et al 2021)

    A Similar Kind of Exercise Intolerance is Found in Connective Tissue Diseases, ME/CFS and Long COVID Results The study found that the blood vessels of people with CTD did not dilate as much as the healthy controls. The CTD patients also displayed an “impaired stroke volume increase”. As their...

    Orthostatic Intolerance Basics: Dysautonomia of Blood Vessels, Low Blood Volume, and Baroreflexes

    I just read a good overview article covering all the basics of orthostatic intolerance: Common Syndromes of Orthostatic Intolerance (Stewart, 2013) https://www.ncbi.nlm.nih.gov/labs/pmc/articles/PMC3639459/pdf/peds.2012-2610.pdf (or https://dx.doi.org/10.1542/peds.2012-2610) This paper starts...

    Long Covid - persistent dyspnea and exercise intolerance

    I noticed that Dr. David Systrom published a paper that resonates a lot with what I have been experiencing. Persistent Exertional Intolerance after COVID-19: Insights from Invasive Cardiopulmonary Exercise Testing. https://journal.chestnet.org/article/S0012-3692(21)03635-7/fulltext They...

    Cardiopulmonary Exercise Test Methodology for Assessing Exertion Intolerance in ME/CFS (Stevens et al., 2018)

    I don't think this paper has been posted yet, but it's a good review of the studies that look at CardioPulmonary Exercise Tests (CPET) to document exercise intolerance in ME. Cardiopulmonary Exercise Test Methodology for Assessing Exertion Intolerance in ME/CFS (Stevens et al., 2018)...

    Unexplained exertional dyspnea caused by low ventricular filling pressures: results from clinical invasive cardiopulmonary exercise testing

    This isn't about ME, but some of the patients had POTS, and this is discussed in the context of exercise testing. Thought the results might be of interest to some here. I have pulled out one of the relevant sections and quoted it (below the abstract)...
