Syncope and orthostatic hypotension
The American Journal of Medicine, 1991The purpose of this study was to determine the postural blood pressure response over time, the prevalence of orthostatic hypotension in patients with syncope, and the relationship of orthostatic hypotension to recurrence of symptoms.We prospectively evaluated 223 patients with syncope in a standardized manner.

Orthostatic hypotension: A review
Néphrologie & Thérapeutique, 2017Orthostatic hypotension, defined by a drop in blood pressure of at least 20mmHg for systolic blood pressure and at least 10mmHg for diastolic blood pressure within 3minutes of standing up, is a frequent finding, particularly in elderly patients. It is associated with a significant increase in morbidity and mortality. Although it is often multifactorial,

Treatment of Orthostatic Hypotension
Seminars in Neurology, 2003Orthostatic hypotension is the most incapacitating symptom of autonomic failure. This disorder occurs with both central autonomic neurodegenerative disorders, such as multiple system atrophy and Parkinson's disease, and peripheral autonomic disorders, such as the autonomic peripheral neuropathies and pure autonomic failure. The hallmark of both central

Idiopathic Orthostatic Hypotension
Archives of Neurology, 1971A case of idiopathic orthostatic hypotension (IOH) is presented with clinical and autopsy data. Electron microscopic examination identifies previously described eosinophil bodies in the sympathetic ganglia as axonal swellings. The case presented is correlated with data from literature.

Management of orthostatic hypotension
American Journal of Health-System Pharmacy, 1994The pathogenesis, clinical manifestations, and management of orthostatic hypotension (OH) are reviewed. OH is a decline in blood pressure that occurs when one moves from a lying to a standing position that results in symptoms of cerebral hypoperfusion, most commonly lightheadedness and syncope.

Cardiology in Review, 2001
Upright posture requires rapid and effective circulatory and neurologic compensations to maintain blood pressure and consciousness. Although it has been recognized over the past 100 years or more that the act of standing may cause hypotension in patients with autonomic dysfunction, only recently several of the pathophysiologic mechanisms resulting in ...

Treatment of orthostatic hypotension
Current Opinion in Pharmacology, 2002Orthostatic hypotension (OH) is a fall in blood pressure after assuming an upright position. Whereas asymptomatic patients usually need no treatment, the majority of symptomatic patients can be cured by avoidance of trigger mechanisms and the use of physical countermaneuvers and non-pharmacological interventions.

Orthostatic hypotension and birthweight
Archives of Gynecology and Obstetrics, 1991This study was designed to test two hypotheses. First, that the changes in arterial blood pressure, induced by a transition from a lying to a standing position, are different in early and late pregnancy. Second, that birthweight is related to the change in mean arterial blood pressure in late pregnancy such that those patients whose pressure fell on ...

Orthostatic Hypotension in Pediatrics
Heart Disease, 2002Transient orthostatic hypotension is a common experience of many healthy adolescents and is the expected outcome of relatively dilated-dependent vascular tone. These children may experience brief symptoms of orthostatic intolerance when standing up rapidly, but they have no chronic symptoms or diseases.

Hypotension Unawareness in Profound Orthostatic Hypotension
The American Journal of Medicine, 2009Clinicians depend on history given by the patients when considering the diagnosis of orthostatic hypotension.Patients with a decrease in systolic blood pressure more than 60 mm Hg from baseline during a head-up tilt table test were included. They were classified according to their symptoms during the head-up tilt table test.
