Resistant Hypertension, Obesity, Sleep Apnea, and Aldosterone: Theory and Therapy

Goodfriend, Theodore L., Calhoun, David A.·2004·Hypertension

Abstract

Hypertension resistant to 2 antihypertensive drugs is more common among obese patients than among lean patients. The case we describe and the observations we report suggest that refractoriness among obese hypertensives is frequently caused by obstructive sleep apnea and/or inappropriately high plasma aldosterone levels. In other words, obese hypertensives may have sleep apnea, obese hypertensives without sleep apnea may have inappropriately elevated levels of plasma aldosterone, and a surprising number of obese patients with sleep apnea also have elevated levels of aldosterone. The mechanisms by which obesity and obstructive sleep apnea increase aldosterone levels and raise blood pressure are not understood, but sympathetic nervous system activation and production of nonclassical adrenal stimuli are two possibilities. Obstructive sleep apnea can be detected with a careful history and various sleep studies. Inappropriately elevated aldosterone levels can be detected by measuring the ratio of plasma aldosterone concentration to plasma renin activity. Successful treatment of these resistant hypertensives often can be achieved by devices that provide positive pressure to the upper airway to correct obstructive sleep apnea and by incorporating an aldosterone antagonist in the therapeutic regimen.

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.
