Symptoms associated with orthostatic hypotension in pure autonomic failure and multiple system atrophy

Abstract

The symptoms caused by or relating to orthostatic hypotension (over 20 mmHg systolic blood pressure) were evaluated using a questionnaire in 72 patients with primary chronic autonomic failure, 32 of whom had pure autonomic failure (PAF, and 40 multiple system atrophy (MSA). The most common posturally related symptoms were dizziness (84% PAF, 83% MSA), syncope (91% PAF, 45% MSA), visual disturbances (75% PAF, 53% MSA) and suboccipital/paracervical 'coat-hanger' neck pain (8 l% PAF, 53% MSA). Chest pain occurred mainly in patients with PAF (44% PAF, 13% MSA). Improvement occurred with sitting or lying flat. Non-specific symptoms (weakness, lethargy and fatigue) were common in both groups (91% PAF, 85% MSA); six patients (one PAF, five MSA) had these symptoms only. Postural symptoms (mainly dizziness and neck pain) were worse in the morning and with warm temperature, straining, exertion, arm movements and food ingestion; they were more common in PAF. Compensatory autonomic symptoms, such as palpitations and sweating, did not occur in either group. In conclusion, orthostatic hypotension caused symptoms of cerebral hypoperfusion (syncope, dizziness and visual disturbances); neck pain, presumably due to muscle hypoperfusion, also occurred frequently. These symptoms were exacerbated by various factors in daily life and were relieved by returning to the horizontal. Non-specific symptoms (such as fatigue) also were common. In MSA, despite substantial orthostatic hypotension, fewer patients had syncope, visual disturbance and neck pain; the reasons for this are unclear. Lack of these features does not exclude the need to assess and investigate orthostatic hypotension and possible autonomic failure.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
