Objectives.This study investigated the association between orthostatic hypotension (OH), supine hypertension (SH), and cognitive performance.
Syncope is a common event with many possible etiologies, ranging from benign to severe. Syncopal episodes of any origin, however, may result in traumatic injury due to postural collapse. Based on the...
Syncope in the aging population has two characteristics--it always has a multifactorial origin and age by itself is a predictor of a worse outcome even in syncope with an apparent benign mechanism. Th...
The commonly accepted pathophysiological changes in cough syncope include a fall in systemic blood pressure, raised intracranial pressure and cerebral ischemia. However, cases of cough syncope without...
Falls are devastating events and are the largest contributor towards injury-related hospitalization of older adults. Orthostatic hypotension (OH) represents an intrinsic risk factor for falls in older...
ISSUE 3 is a multi-center, prospective, randomised controlled double-blind study aimed to assess the effectiveness of pacemaker therapy for prevention of asystolic neurally-mediated synco...
The purpose of this study is to determine whether Fipamezole is effective in the treatment of orthostatic hypotension and related symptoms in multiple system atrophy and Parkinson's diseas...
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...
OBJECTIVES: I. Study further the safety and efficacy of the alpha-receptor agonist midodrine in patients with neurogenic orthostatic hypotension. II. Assess the quality of life in these...
The purpose of this study is to see whether droxidopa is effective in treating symptoms of neurogenic orthostatic hypotension in patients with Primary Autonomic Failure (Pure Autonomic Fai...
Medical and Biotech [MESH] Definitions
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 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.
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. (From Adams et al., Principles of Neurology, 6th ed, p1348; Nat Genet 1993;4(2):160-4)
A degenerative disease of the AUTONOMIC NERVOUS SYSTEM that is characterized by idiopathic ORTHOSTATIC HYPOTENSION and a greatly reduced level of CATECHOLAMINES. No other neurological deficits are present.
