16 maj 2023 · Etiology. Orthostatic hypotension can be caused by both neurogenic and non-neurogenic etiologies and can also be related to medications. Neurogenic orthostatic hypotension is characterized by autonomic instability secondary to neuropathic disease, neurodegenerative disease, or aging.
Orthostatic hypotension (OH) leads to a significant number of hospitalizations each year, and is associated with significant morbidity and mortality among affected individuals. Given the increased risk for cardiovascular events and falls; it is important to identify the underlying etiology of OH and to choose appropriate therapeutic agents.
15 kwi 2019 · Purpose: Orthostatic hypotension (OH) is a common and clinically important disorder. Published papers vary regarding the definitions of OH and methodologies of evaluation. Moreover, substantial gaps in the skills and knowledge required for assessment of OH have been reported by clinicians.
18 sie 2015 · Orthostatic hypotension (OH) is a key manifestation of autonomic dysfunction, typically observed when cardiovascular adaptive mechanisms fail to compensate for the reduction in venous return that normally occurs on assuming the upright position.
Orthostatic (postural) hypotension is an excessive fall in blood pressure (BP) when an upright position is assumed. The consensus definition is a drop of > 20 mm Hg systolic, > 10 mm Hg diastolic, or both (1).
Etiology of Primary and Secondary Chronic Autonomic Failure With Symptoms of Orthostatic Hypotension. Orthostatic hypotension caused by primary disease of the autonomic nervous system (left panel) is often referred to as neurogenic orthostatic hypotension. AV = atrioventricular.
6 sty 2009 · Orthostatic hypotension (OH) is defined as a persistent, consistent, orthostatic fall in systolic blood pressure of ≥20 mm Hg or diastolic pressure of ≥10 mm Hg by 3 minutes of standing up. 1 Acute, unexpected, episodic falls in blood pressure while standing, as in neurocardiogenic syncope, do not satisfy criteria for OH.
