Long COVID Patients Show Autonomic Dysfunction and Inflammatory Markers, Urging Autonomic Assessment
A recent Australian study, published in the Journal of the American Heart Association, indicates that nearly 60% of long COVID patients were unable to return to work after their infection. The study found that individuals with long COVID, similar to those with postural orthostatic tachycardia syndrome (POTS), experienced higher levels of fatigue, orthostatic intolerance, and autonomic symptom burden, alongside a reduced health-related quality of life, when compared to healthy controls. Marie-Claire Seeley, RN, MNurs, PhD, a researcher involved in the study, emphasized the importance of autonomic assessment for long COVID patients, particularly through active standing tests. These tests measure heart rate and blood pressure changes over 10 minutes of standing, with a sustained heart rate increase of at least 30 beats per minute suggesting POTS. The study also identified group-level differences in inflammatory markers, such as lower IL-2 and higher IL-8 levels in POTS patients, though these markers were not ...
