NCT01699126

Brief Summary

study Hypothesis: We hypothesize that CPAP could effectively improve the endothelial dysfunction by anti-inflammatory effect in patients of OSA,and compare to the effect of statin.

Outcome Measures

Primary Outcomes (1)

  • Flow-Mediated dilatation test(FMD)

    FMD is the most sensitive physical marker of endothelial function, we measure the FMD changes after treatment

    6 months

Secondary Outcomes (1)

  • Blood pressure

    6 months

Other Outcomes (2)

  • Hs-CRP

    6 months

  • Inflammatory markers

    6 months

Study Arms (4)

CPAP, Hypertension

EXPERIMENTAL

evaluate the effect on FMD, blood pressure and inflammation after CPAP on OSA

Device: CPAP

CPAP and statin, Hypertension

ACTIVE COMPARATOR

evaluate the effect on FMD, blood pressure and inflammation after CPAP plus statin on OSA patients

Device: CPAPDrug: Statin

OSA, statin, Hypertension

ACTIVE COMPARATOR

evaluate the effect on FMD, blood pressure and inflammation after statin treatment on OSA

Drug: Statin

Placebo

NO INTERVENTION

We will also measure the FMD, blood pressure and inflammation on patients with only life style modification as in all other patients

Interventions

CPAPDEVICE

Continuous Positive Airway Pressure is the routine treatment of OSA, patients will be randomly assigned into CPAP treatment group

CPAP and statin, HypertensionCPAP, Hypertension
StatinDRUG

Statin is an lipid lowering medication with anti-inflammatory effect.

Also known as: rosuvastatin
CPAP and statin, HypertensionOSA, statin, Hypertension

Eligibility Criteria

Age18 Years+

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • \- 1.OSA with AHI\>30 2.Male patients with hypertension 3.LDL over 130 mg/dL without any lipid-lowering drug therapy in recent 6 months 4.Signed inform consent and cooperative

You may not qualify if:

  • \- 1.Non-cooperative 2.Can't sign inform consent. 3.Had proven major cardiovascular complication such as AMI, CVA. 4.Major chronic disorders and inflammatory disorders: such as DM, ESRD, COPD or rheumatoid arthritis. 5.Under anti-inflammatory medication: such as aspirin, NSAID, steroids, theophylline etc. 6.Acute of chronic infection 1 weeks between blood drawing period will be discarded 7.Study medication will be discontinued among subjects who develop myopathy (CK ≥10 times ULN and muscle aches or weakness) or a persistent elevation in ALT (≥3 times ULN on 2 consecutive tests).
