Comparative Analysis of Circulating Cytokines and Adrenergic Autoantibodies in Postural Orthostatic Tachycardia Syndrome, Postacute Sequelae of SARS‐CoV‐2, and Healthy Controls

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Postural orthostatic tachycardia syndrome (POTS) is increasingly recognized after SARS‐CoV‐2 infection. We compared autonomic phenotype, functional impact, and circulating immune markers in POTS, postacute sequelae of COVID‐19 (PASC), and ...

Long COVID Patients with Orthostatic Intolerance Have Reduced Heart Rate Variability and Preserved Physiological Response to Active Standing

Biology
The aim of this study was to assess the heart rate variability (HRV) at rest and during active orthostatic challenge in long COVID patients with orthostatic intolerance symptoms (dizziness, pre-syncope, and syncope).

Prevalence and patterns of symptoms of dysautonomia in patients with long‐COVID syndrome: A cross‐sectional study

Annals of Clinical and Translational Neurology, 2022
Background The association between autonomic dysfunction and long‐COVID syndrome is established. However, the prevalence and patterns of symptoms of dysautonomia in long‐COVID syndrome in a large population are lacking.

The Gut–Heart Axis in Systemic Sclerosis: Evidence From a Large Prospective Early Disease Cohort

Arthritis Care &Research, EarlyView.
Objective Cardiac involvement significantly impacts prognosis in systemic sclerosis (SSc), highlighting the need for early risk stratification. Gastrointestinal (GI) symptoms are common and often manifest early. Emerging data suggest a link between GI and cardiac manifestations, possibly through shared mechanisms like dysautonomia.
