Cardiovascular autonomic dysfunction in post-COVID-19 syndrome: a major health-care burden.

The article discusses cardiovascular autonomic dysfunction (CVAD), a significant complication seen in patients with post-COVID-19 syndrome, also known as long COVID. It affects a large portion of symptomatic COVID-19 patients, often presenting as issues in heart rate and blood pressure regulation, such as postural orthostatic tachycardia syndrome (POTS) or inappropriate sinus tachycardia. Other manifestations may include orthostatic, postprandial hypotension, and reflex syncope. The paper highlights recent advancements in understanding the pathophysiology, diagnosis, and management of CVAD during the COVID-19 pandemic. The authors underscore the importance of recognizing and treating these symptoms in clinical practice and propose future research directions to better address this condition.
