Abstract

Splanchnic venous pooling is a major hemodynamic determinant of orthostatic hypotension, but is not specifically targeted by pressor agents, the mainstay of treatment. We developed an automated inflatable abdominal binder that provides sustained servo-controlled venous compression (40 mm Hg) and can be activated only on standing. We tested the efficacy of this device against placebo and compared it to midodrine in 19 autonomic failure patients randomized to receive either placebo, midodrine (2.5–10 mg), or placebo combined with binder on separate days in a single-blind, crossover study. Systolic blood pressure (SBP) was measured seated and standing before and 1-hour post medication; the binder was inflated immediately before standing. Only midodrine increased seated SBP (31±5 versus 9±4 placebo and 7±5 binder, P =0.003), whereas orthostatic tolerance (defined as area under the curve of upright SBP [AUC SBP ]) improved similarly with binder and midodrine (AUC SBP , 195±35 and 197±41 versus 19±38 mm Hg×minute for placebo; P =0.003). Orthostatic symptom burden decreased with the binder (from 21.9±3.6 to 16.3±3.1, P =0.032) and midodrine (from 25.6±3.4 to 14.2±3.3, P <0.001), but not with placebo (from 19.6±3.5 to 20.1±3.3, P =0.756). We also compared the combination of midodrine and binder with midodrine alone. The combination produced a greater increase in orthostatic tolerance (AUC SBP , 326±65 versus 140±53 mm Hg×minute for midodrine alone; P =0.028, n=21) and decreased orthostatic symptoms (from 21.8±3.2 to 12.9±2.9, P <0.001). In conclusion, servo-controlled abdominal venous compression with an automated inflatable binder is as effective as midodrine, the standard of care, in the management of orthostatic hypotension. Combining both therapies produces greater improvement in orthostatic tolerance. Clinical Trial Registration—: URL: https://www.clinicaltrials.gov . Unique identifier: NCT00223691.

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.
