Compression Stockings Improve Cardiac Output and Cerebral Blood Flow during Tilt Testing in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Patients: A Randomized Crossover Trial Abstract Background and Objectives: Orthostatic intolerance (OI) is a clinical condition in which...

Orthostatic Symptoms and Reductions in Cerebral Blood Flow in Long-Haul COVID-19 Patients: Similarities with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Abstract Background and Objectives: Symptoms and hemodynamic findings during orthostatic stress have been reported in both long-haul...

Highlights Long COVID symptoms include fatigue, brain fog, anosmia, dysgeusia, orthostatic intolerance Long COVId symptoms overlap with those of chronic fatigue syndrome (ME/CFS) and POTS. Reduced cerebral blood flow is a feature of dysautonomia in ME/CFS and POTS. Stellate ganglion block...

Orthostatic intolerance syndromes after hematopoietic cell transplantation: clinical characteristics and therapeutic interventions in a single-center experience Abstract Background Hematopoietic cell transplantation (HCT) is an established and potentially curative therapeutic option for...

Background and Objective: Migraineurs often complain of orthostatic intolerance (OI), and its recognition is vital to appropriate treatment. This study attempts to identify and characterize autonomic dysfunction, comparing a sample of migraineurs with OI with a sample of migraineurs without...

Abstract Salt supplementation is a common non-pharmacological approach to the management of recurrent orthostatic syncope or presyncope, particularly for patients with vasovagal syncope (VVS) or postural orthostatic tachycardia syndrome (POTS), although there is limited consensus on the optimal...

In conclusion, meals do matter in the evaluation and treatment of POTS. There are significant postprandial symptoms in POTS patients, which are related to exaggerated postprandial tachycardia. Possible mechanisms include enhanced splanchnic blood pooling, an increased secretion of vasoactive...

Dr Jenny Butler, Consultant Physician - General Medicine, at Christchurch Hospital, is joining us online on Wed, 10th Nov 1.30pm to talk about Orthostatic Intolerance. Many people with ME/CFS (Myalgic Encephalomyelitis /Chronic Fatigue Syndrome) experience triggering or worsening of symptoms...

Abstract Background: Postural tachycardia syndrome (POTS) is a form of autonomic dysregulation and is characterized by an excessive heart rate (HR) increment upon the upright body position while blood pressure is maintained. Patients experience typical symptoms of orthostatic intolerance such as...

New paper on Salt: The paradoxical philosopher's stone of autonomic medicine - to expand intravascular volume or to raise blood pressure. Highlights Salt has profoundly shaped human history, including diet and medicine. • Salt improves orthostatic tolerance but also increases risk of...

Mod note: A number of posts have been moved from a useful study on this subject: Compression Garment Reduces Orthostatic Tachycardia and Symptoms in Patients With [POTS], 2021, Bourne et al This is very interesting. I use compression wear, and swear it helps keep me functioning longer...

Compression Garment Reduces Orthostatic Tachycardia and Symptoms in Patients With Postural Orthostatic Tachycardia Syndrome Kate M. Bourne et al "Abstract Background Postural orthostatic tachycardia syndrome (POTS) is a chronic form of orthostatic intolerance associated with a significant...

https://pubmed.ncbi.nlm.nih.gov/34484936/ Abstract Objective: Postural tachycardia syndrome (POTS), the most common form of dysautonomia, may be associated with autoimmunity in some cases. Autoantibodies against the ganglionic acetylcholine receptor (gAChR) have been reported in a minority of...

Post-Covid-19 Tachycardia Syndrome: A distinct phenotype of Post-acute Covid-19 Syndrome Ståhlberg, Fedorowski et al Abstract In this paper we highlight the presence of tachycardia in Post-acute Covid-19 Syndrome by introducing a new label for this phenomenon: Post-covid-19 tachycardia...

Abstract Key points The impact of SARS-CoV-2 infection on autonomic and cardiovascular function in otherwise healthy individuals is unknown. We show for the first time that young adults recovering from SARS-CoV-2 have elevated resting sympathetic activity, but similar heart rate and blood...

Abstract The autonomic nervous system (ANS) can be affected by COVID-19, and dysautonomia may be a possible complication in post-COVID individuals. Orthostatic hypotension (OH) and postural tachycardia syndrome (POTS) have been suggested to be common after SARS-CoV-2 infection, but other...

(Very unsure where to put this, not quite guidelines, related to ME, but not research either) (Also unsure why it took 2 years to publish this but it's new) Part 1 of 2 (according to this tweet). https://www.sciencedirect.com/science/article/pii/S1566070221000588 Abstract Postural...

The Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Patients with Joint Hypermobility Show Larger Cerebral Blood Flow Reductions during Orthostatic Stress Testing Than Patients without Hypermobility: A Case Control Study Linda M.C. van Campen Stichting CardioZorg, Planetenweg 5, 2132 HN...

Abstract This review recapitulates the head-up tilt test, which is commonly used for evaluation of orthostatic syndromes and dysautonomia. Tilt test evaluates autonomic system responses to orthostatic stress. Established tilt testing includes monitoring of heart rate and blood pressure...
