Abstract

BACKGROUND: Obstructive sleep apnea (OSA) may lead to the development of hypertension and therapy with continuous positive airway pressure (CPAP) can promote reduction in blood pressure. OBJECTIVE: The objective of this study is to review systematically the effects of CPAP on blood pressure in patients with OSA. METHODS: The search was conducted in the following databases, from their beginning until February 2013: MEDLINE, Embase, Cochrane CENTRAL, Lilacs and PEDro. In addition, a manual search was performed on references of published studies. Randomized clinical trials (RCTs) that used CPAP compared with placebo CPAP or subtherapeutic CPAP for treatment of patients with OSA and that evaluated office SBP and DBP and 24-h ambulatory blood pressure were selected. RESULTS: Sixteen RCTs were included among 3409 publications, totaling 1166 patients. The use of CPAP resulted in reductions in office SBP [-3.20 mmHg; 95% confidence interval (CI) -4.67 to -1.72] and DBP (-2.87 mmHg; 95% CI -5.18 to -0.55); in night-time SBP (-4.92 mmHg; 95% CI -8.70 to -1.14); in mean 24-h blood pressure (-3.56 mmHg; 95% CI -6.79 to -0.33), mean night-time blood pressure (-2.56 mmHg; 95% CI -4.43 to -0.68) and 24-h DBP (-3.46 mmHg; 95% CI -6.75 to -0.17). However, no significant change was observed in daytime SBP (-0.74 mmHg; 95% CI -3.90 to 2.41) and daytime DBP (-1.86 mmHg; 95% CI -4.55 to 0.83). CONCLUSION: Treatment with CPAP promoted significantly but small reductions in blood pressure in individuals with OSA. Further studies should be performed to evaluate the effects of long-term CPAP and the impact on cardiovascular risk.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Better oxygenation through night-time continuous positive air pressure reduces nocturnal hypertension and reduces catecholamines and aldosterone secretion.

    “Further, better oxygenation through night‐time continuous positive air pressure reduces nocturnal hypertension 65 and reduces catecholamines and aldosterone secretion 66.”

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.
