A new study found that (79%) of those with post-covid-19 (PASC) or Long COVID met internationally defined criteria for POTS.
The study was published in American Journal of Medicine.
“Overall, 79%, 79% of the Delta’s Delta Dance’s Dancelist Comment the decline of a temporary systolic blood pressure more than 20 mmhg within the first minute of standing in the third minute.
Patients aged 18 years and older with PASC and POTS, who presented at a specialist cardiology clinic were invited to participate in a prospective comparative study. A total of 99 participants were included in 3 groups: 33 with PASC, 33 with POTS, and 33 in the healthy control group.
According to the investigation, participants underwent automatic tests including hemodynamic monitoring to assess respiratory sinus disorders, Valsalva ratio and orthostatic changes during a 10-minute movement test as well as Sudomotor evaluation. The Symptom Autonomic Composite score (COMPASS-31) was used to evaluate symptoms and the Euroquol 5-Dimension survey (EQ-5D-5L) was used to evaluate health-related quality of life (HrQoL), they explained.
According to the National Institute of Neurological Disorders and Stroke, POTS is characterized by “One of a group of disorders that have orthostatic intolerance (OI) as their primary symptom. OI is a condition in which an excessively reduced volume of blood returns to the heart after a person stands up from a lying position. .The main symptom of OI is light-headedness or fainting.”
It mainly affects women between 15-50 years of age, and the cause of the disorder is unknown.
POTS, COVID-19 and vaccinations
In another study, which was published in Research on cardiovascular nature Late last year, investigators pointed to an increased incidence of POTS for people who have been vaccinated or who have had COVID-19.
“We show, in a group of 284,592 individuals vaccinated against COVID-19, using a sequence-symmetry analysis, that the odds of POTS are higher 90 days after exposure to the vaccine than 90 days before exposure; we also show that the odds for POTS are higher than a conventional primary care diagnosis referred but lower than the chance of a new POTS diagnosis after SARS-CoV-2 infection,” the investigators wrote.
They also reported that people with COVID-19 were reported to have POTS at a rate five times higher than the incidence of POTS after the COVID-19 vaccine.
American Journal of Medicine The authors see a long-standing link between COVID and POTS. “This study provides empirical evidence of the high prevalence of autonomic symptoms or POTS in people with PASC. The significant impairment in HrQOL and the reduction of health benefits in people with PASC require urgent attention from physicians, health services and governments to improve the care of those affected.
They also noted a possible link for COVID-19 as a possible trigger for dysautonomia.
“Notably, the majority of participants with PASC in this study reported mildly severe COVID-19 infection and the delay in onset of autonomic symptoms within at least two weeks from acute infection lends further support to COVID-19 as a cause of dysautonomia.”
