The aim of the study is to evaluate whether orthostatic hypotension is associated with nondipping hypertension. Methods and patients: 400 subjects who are referred for 24hABPM will be fil...
Orthostatic hypotension following total hip arthroplasty is known to limit the ability of patients to perform physical therapy (PT) and increase the length of hospital stay and costs. Our ...
We are seeking male and female patients to voluntarily take part in a clinical research study. Patients must be aged 18 or older and diagnosed with symptomatic orthostatic hypotension (lo...
In clinical trials in Japan, droxidopa has been shown to be effective in affecting blood pressure changes upon orthostatic challenge in patients with autonomic dysfunction, as well as redu...
The aim of the study is to investigate the value of the Hypotension Probability Index in reducing intraoperative hypotension in patients with primary hip replacement. The measurement of th...
Standing and Supine Blood Pressure Outcomes Associated With Droxidopa and Midodrine in Patients With Neurogenic Orthostatic Hypotension: A Bayesian Meta-analysis and Mixed Treatment Comparison of Randomized Trials.
The comparative effects of droxidopa and midodrine on standing systolic blood pressure (sSBP) and risk of supine hypertension in patients with neurogenic orthostatic hypotension (NOH) are unknown.
Orthostatic hypertension was associated with worse cardiovascular outcomes, although the factors responsible for an orthostatic rise in blood pressure (BP) are uncertain. We investigated a possible re...
The objective of the study was to identify markers of hypocapnic cerebral hypoperfusion (HYCH) in patients with orthostatic intolerance (OI) without tachycardia and without orthostatic hypotension. Th...
Arterial hypotension is a frequently encountered phenomenon in clinical practice. It is responsible for multiple consultations and/or hospitalizations, mostly in elderly people. It is associated with ...
Orthostatic hypotension and symptomatic subclinical orthostatic hypotension increase risk of cognitive impairment: an integrated evidence review and analysis of a large older adult hypertensive cohort.
Systematically reviewing the literature found orthostatic hypotension (OH) to be associated with an increased risk of incident dementia but limited data were available in those at highest risk, the hy...
A significant drop in BLOOD PRESSURE after assuming a standing position. Orthostatic hypotension is a finding, and defined as a 20-mm Hg decrease in systolic pressure or a 10-mm Hg decrease in diastolic pressure 3 minutes after the person has risen from supine to standing. Symptoms generally include DIZZINESS, blurred vision, and SYNCOPE.
Symptoms of cerebral hypoperfusion or autonomic overaction which develop while the subject is standing, but are relieved on recumbency. Types of this include NEUROCARDIOGENIC SYNCOPE; POSTURAL ORTHOSTATIC TACHYCARDIA SYNDROME; and neurogenic ORTHOSTATIC HYPOTENSION. (From Noseworthy, JH., Neurological Therapeutics Principles and Practice, 2007, p2575-2576)
A syndrome of ORTHOSTATIC INTOLERANCE combined with excessive upright TACHYCARDIA, and usually without associated ORTHOSTATIC HYPOTENSION. All variants have in common an excessively reduced venous return to the heart (central HYPOVOLEMIA) while upright.
An autosomal disorder of the peripheral and autonomic nervous systems limited to individuals of Ashkenazic Jewish descent. Clinical manifestations are present at birth and include diminished lacrimation, defective thermoregulation, orthostatic hypotension (HYPOTENSION, ORTHOSTATIC), fixed pupils, excessive SWEATING, loss of pain and temperature sensation, and absent reflexes. Pathologic features include reduced numbers of small diameter peripheral nerve fibers and autonomic ganglion neurons.

The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine.
