Abstract

BACKGROUND: Experimentally induced sleep deprivation can raise blood pressure (BP) and worsen hypertension. We recently reported a significantly higher prevalence of obstructive sleep apnea (OSA) and reduced rapid eye movement (REM) sleep time in drug-resistant hypertensives compared to controlled hypertensives. The objective of this study was to test the hypothesis that short sleep duration is associated with resistant hypertension (RH) independently of OSA, which can itself disrupt and shorten sleep. METHODS: In a case-control study, overnight polysomnographic results of subjects with OSA and RH (n = 62) were compared to those with OSA of equal severity and either controlled hypertension (CH) (n = 49) or normotension (n = 40). RESULTS: Subjects with RH slept 33.8 min (P = 0.02) and 37.2 min (P = 0.02) less than those with CH and normotension, respectively. Consequently, sleep efficiency was reduced by 7.9% (P = 0.007) and 10.2% (P = 0.002), respectively. They also spent 9.7 min (P = 0.06) and 11.6 min (P = 0.04) less time in REM sleep compared to those with CH and normotension, respectively. Older age, greater body mass index (BMI) and greater apnea-hypopnea index (AHI) were also associated with shorter sleep time (P = 0.02, P = 0.001, and P = 0.03, respectively) and reduced sleep efficiency (P = 0.0003, P = 0.03, and P = 0.01, respectively). CONCLUSIONS: Our study demonstrates that, compared to subjects with CH or normotension, those with RH have shorter total and REM sleep times and lower sleep efficiency independently of OSA. These data suggest that reduced sleep time may contribute to the severity of hypertension.

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.
