Selected biomarkers of orthostatic intolerance
Vnitřní lékařství, 2023Orthostatic intolerance (OI) is defined as a group of diseases which symptoms are typically manifested in a standing position. These symptoms result from cerebral hypoperfusion and disappear in the supine position. We include postural orthostatic intolerance syndrome (POTS), orthostatic hypotension (OH) and vasovagal orthostatic syncope in this group ...

Early postoperative mobilization can be hindered by orthostatic intolerance (OI) due to failed orthostatic cardiovascular regulation. The underlying mechanisms are not fully understood and specific data after total knee arthroplasty (TKA) are lacking ...

Orthostatic intolerance after spaceflight
Journal of Applied Physiology, 1996Orthostatic intolerance occurs commonly after spaceflight, and important aspects of the underlying mechanisms remain unclear. We studied 14 individuals supine and standing before and after three space shuttle missions of 9-14 days. After spaceflight, 9 of the 14 (64%) crew members could not complete a 10-min stand test that all completed preflight ...

Syncope and orthostatic intolerance
Medical Clinics of North America, 2003Syncope and orthostatic intolerance remain common and significant clinical problems with many undocumented, misdiagnosed, or cryptogenic cases. Careful clinical assessment and application of advancing laboratory support can further improve diagnosis and treatment.

Orthostatic intolerance after bariatric surgery: A systematic review and meta‐analysis
Clinical Obesity, 2021There have been increased reports of orthostatic intolerance post‐bariatric surgery. However, the prevalence, pathophysiology and long‐term outcomes have not been well described. Therefore, we sought to summarize evidence of orthostatic intolerance after

Orthostatic Intolerance in Behcet's Disease
Autonomic Neuroscience, 2001Neurological manifestations are known to occur in patients with Behcet's Disease (BD) and significantly affect the clinical course of the disease. Nevertheless, the prevalence, pattern and severity of autonomic impairment in such patients have yet to be defined. In this paper, we presented a BD patient with orthostatic tachycardia.

Orthostatic Intolerance and Chiari I Malformation
Neurosurgery Clinics of North America, 2023Individuals with Chiari malformation can present with symptoms of fatigue, lightheadedness, and syncope-the cardinal features of orthostatic intolerance. Similar orthostatic symptoms can complicate the clinical course following Chiari decompression. The presence of orthostatic intolerance in patients with Chiari malformation is not surprising given the

Cerebral Autoregulation in Orthostatic Intolerance
Annals of the New York Academy of Sciences, 2001Abstract: Many of the primary symptoms of orthostatic intolerance (fatigue, diminished concentration) as well as some of the premonitory symptoms of neurally mediated syncope (NMS) are thought to be due to cerebral hypoperfusion. Transcranial Doppler measurements of middle cerebral artery blood velocity (CBV) is at present the only technique for ...
