Abstract |
Background |
Autonomic dysfunction, including postural orthostatic tachycardia syndrome (POTS), has been reported in individuals with post-acute sequelae of COVID-19 (PASC). However, the degree of dysautonomia in PASC has not been compared to those with POTS and healthy controls.
Methods |
All participants were prospectively enrolled between August 5, 2021 and October 31, 2022. Autonomic testing included beat-to-beat hemodynamic monitoring to assess respiratory sinus arrhythmia, Valsalva ratio, and orthostatic changes during a 10-minute active standing test, as well as sudomotor assessment. The Composite Autonomic Symptom Score (COMPASS-31) was used to assess symptoms and the EuroQuol 5-Dimension survey (EQ-5D-5L) was used to assess health-related quality of life (HrQoL) measures.
Results |
A total of 99 participants (n = 33 PASC, n = 33 POTS, and n = 33 healthy controls; median age 32 years, 85.9% females) were included. Compared with healthy controls, the PASC and POTS cohorts demonstrated significantly reduced respiratory sinus arrhythmia (P < .001), greater heart rate increase during 10-minute active standing test (P < .001), greater burden of autonomic dysfunction evidenced by higher COMPASS-31 scores across all subdomains (all P < .001), and poor HrQoL across all EQ-5D-5L domains (all P < .001), lower median EuroQol-visual analogue scale (P < .001), and lower utility scores (P < .001). The majority (79%) of those with PASC met the internationally established criteria for POTS.
Conclusion |
The prevalence of autonomic symptomology for POTS was high in those with PASC, leading to poor HrQoL and high health disutility. Autonomic testing should be routinely undertaken in those with PASC to aid diagnosis and direct appropriate management to improve health outcomes.
