Abstract Background/Objectives: Orthostatic intolerance is prevalent in patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and is caused by an abnormal reduction in cerebral blood flow (CBF). In healthy controls (HCs), CBF is regulated complexly, and cardiac output (CO) is...

Influence of end-tidal CO2 on cerebral blood flow during orthostatic stress in controls and adults with myalgic encephalomyelitis/chronic fatigue syndrome C. (Linda) M. C. van Campen; Peter C. Rowe; Freek W. A. Verheugt; Frans C. Visser Brain perfusion is sensitive to changes in CO2 levels (CO2...

Introduction: During a standard 70-degree head-up tilt test, 90% of adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) develop an abnormal reduction in cerebral blood flow (CBF). A 70-degree test might not be tolerated by young ME/CFS patients because of the high incidence...

authors van Campen, Frank Visser Abstract Background: Postural orthostatic tachycardia syndrome (POTS) has been described early after the onset of the COVID-19 infection, but also orthostatic hypotension (OH). In the present study, we hypothesized that orthostatic intolerance decreases over...

Abstract Background: As complaints of long-haul COVID patients are similar to those of ME/CFS patients and as orthostatic intolerance (OI) plays an important role in the COVID infection symptomatology, we compared 14 long-haul COVID patients with 14 ME/CFS patients with a post-viral Ebstein-Barr...

Background: Orthostatic intolerance (OI) is a core finding in individuals with myalgic encephalomyelitis /chronic fatigue syndrome (ME/CFS). Deconditioning is often proposed as an important determinant for OI. Deconditioning can be objectively classified using the predicted peak oxygen...

Introduction: In patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) a higher-than-normal resting heart rate has been reported in a number of studies. As heart rate is linked to stroke volume, the present study explored the relationship between the supine heart rate and...

Abstract Background and objectives: Orthostatic intolerance (OI) is a clinical condition in which symptoms worsen upon assuming and maintaining upright posture and are ameliorated by recumbency. OI has a high prevalence in patients with myalgic encephalomyelitis/chronic fatigue syndrome...

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...

https://www.mdpi.com/2227-9032/9/6/682 C. (Linda) M. C. van Campen Frans C. Visser Abstract Introduction: Multiple studies have shown that peak oxygen consumption is reduced in the majority of ME/CFS patients, using the golden standard for measuring exercise intolerance: cardiopulmonary...

Highlights • Cerebral blood flow in ME/CFS patients remains abnormal 5 minutes post-tilt test. • Post cerebral blood flow abnormalities do not depend on hemodynamic results and on end-tidal carbon dioxide pressures during the tilt-test. • Post cerebral blood flow abnormalities are most severe...

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...

Deconditioning does not explain orthostatic intolerance in ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome) Abstract Background Orthostatic intolerance (OI) is a frequent finding in individuals with myalgic encephalomyelitis /chronic fatigue syndrome (ME/CFS). Published studies...
