Objective Hemodynamic Cardiovascular Autonomic Abnormalities in Post-Acute Sequelae of COVID-19.

In this study, researchers investigated the prevalence of cardiovascular autonomic abnormalities (CAA) among patients experiencing post-acute sequelae of COVID-19 (PASC), a condition characterized by prolonged symptoms following initial COVID-19 recovery. The study included 70 patients, predominantly female, who underwent standard autonomic function tests over a year after their COVID-19 infection. It was found that a significant majority (73%) of these patients exhibited at least one form of CAA, predominantly presenting as postural orthostatic tachycardia syndrome (POTS) or initial orthostatic hypotension (IOH). The study highlights the common presence of autonomic dysregulation in PASC patients, particularly concerning postural changes, and underscores the importance of recognizing these abnormalities in patients with long COVID.
