The impact of orthostatic intolerance on early ambulation following abdominal surgery in an enhanced recovery programme.

open access: yes, 2022
peer reviewedBACKGROUND: The prevalence of orthostatic intolerance on the day of surgery is more than 50% after abdominal surgery. The impact of orthostatic intolerance on ambulation on the day of surgery has been little studied.

Other Syndromes of Orthostatic Intolerance: Delayed Orthostatic Hypotension, Postprandial Hypotension, Postural Orthostatic Tachycardia Syndrome, and Reflex Syncope

open access: yes, 2020
Apart from classical orthostatic hypotension, the gravitational force may strongly contribute to other forms of orthostatic intolerance, delayed and postprandial OH, postural orthostatic tachycardia syndrome (POTS), and reflex syncope. In delayed OH, the

Mechanisms of orthostatic intolerance during heat stress [PDF]

open access: yes, 2016
Postprint, author's accepted manuscriptHeat stress profoundly and unanimously reduces orthostatic tolerance. This review aims to provide an overview of the numerous and multifactorial mechanisms by which this occurs in humans.

Acute fluid ingestion in the treatment of orthostatic intolerance - important implications for daily practice

open access: yes, 2010
Rapid water ingestion improves orthostatic intolerance (OI) in multiple system atrophy (MSA) and postural tachycardia syndrome (PoTS). We compared haemodynamic changes after water and clear soup intake, the latter being a common treatment strategy for OI

An Unusual Case of Polyautoimmunity with Concomitant Presentation of Postural Tachycardia Syndrome, Antiphospholipid Syndrome and Hashimoto’s Thyroiditis

open access: yesClinical and Translational Neuroscience, 2021
Introduction: Postural tachycardia syndrome (POTS) is a chronic form of autonomic dysfunction characterized by symptoms of orthostatic intolerance, often accompanied by sudomotor dysfunction and gastrointestinal dysmotility.

Common Syndromes of Orthostatic Intolerance [PDF]

open access: yesPediatrics, 2013
The autonomic nervous system, adequate blood volume, and intact skeletal and respiratory muscle pumps are essential components for rapid cardiovascular adjustments to upright posture (orthostasis). Patients lacking sufficient blood volume or having defective sympathetic adrenergic vasoconstriction develop orthostatic hypotension (OH), prohibiting ...

Chinese Expert Consensus on the Clinical Application of Finerenone in Geriatric Comorbidities

open access: yesAGING MEDICINE, EarlyView.
Mineralocorticoid receptor (MR) overactivation drives inflammation, oxidative stress, and fibrosis in the heart, kidneys, and vasculature, leading to cardiorenal dysfunction. MR signaling promotes hypertrophy, remodeling, and injury through pathways like oxidative stress and inflammation, resulting in vascular stiffness and progressive organ damage ...
