Abstract

Study objective To examine the long-term effects of continuous positive airway pressure (CPAP) therapy on blood pressure (BP) in patients with obstructive sleep apnea and resistant hypertension.Methods Study subjects were 98 patients with obstructive sleep apnea syndrome and hypertension who had 3 or more documented daytime BP measurements taken within 3 months of enrollment and every 3 months after CPAP initiation for 1 year. Resistant hypertension was defined as daytime BP of at least 140 mm Hg systolic or 90 mm Hg diastolic, despite the use of 3 or more antihypertensive medications. Patients in the resistant hypertension group (n = 42) were compared with subjects with controlled hypertension (n = 56).Results Mean difference in mean arterial pressure was -5.6 (95% confidence interval [CI] -2.0 to -8.7 mm Hg; p = 0.03) in the resistant group and -0.8 mm Hg (95% CI -2.9 to 3.3 mm Hg; p = 0.53) in patients with controlled BP at the end of follow up period. CPAP permitted de-escalation of antihypertensive treatment in 71% of subjects with resistant hypertension but did not significantly alter the antihypertensive regimen in the controlled group. Multivariate regression analysis showed that baseline BP (odds ratio 5.4, 95% CI 2.3 to 8.9; p = 0.01) and diuretic therapy (odds ratio = 3.2, 95% CI 1.8 to 6.1; p = 0.02), but not apnea-hypopnea index or hours of CPAP use, were independently associated with a decrease in mean arterial pressure after 12 months of CPAP therapy.Conclusion In this observational study, CPAP was associated with different effects on blood pressure control in hypertensive patients with sleep apnea. A beneficial response to CPAP therapy was found mainly in subjects with the most severe hypertensive disease.

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.
