Sleep Apnea in Cerebrovascular Disease

This study seeks to evaluate a diagnostic and therapeutic intervention strategy among veterans with cerebrovascular disease, hypertension and obesity that consists of using unattended sleep studies to diagnose sleep apnea and CPAP to treat sleep apnea. It is hypothesized that the intervention strategy will (1) reduce hypertension at the end …

Optimal Dosage of Acetazolamide for OSA Treatment

Acetazolamide, a carbonic anhydrase inhibitor, has received some attention as potential treatment for obstructive sleep apnea (OSA). It produces a metabolic acidosis by excreting bicarbonate, thereby stimulating baseline ventilation. Evidence suggests that acetazolamide primarily improves ventilatory control instability (expressed as loop gain), which is an important contributor to the pathophysiology …

Validation of Sleep Questionnaires in the Down Syndrome Population

This will be a prospective validation study of a sample of consecutive pediatric Down syndrome patients who are seen through the weekly Down syndrome clinic at OHSU/Doernbecher's. Questionnaires will be administered to approximately 5 new patients per month. Since this population has a higher prevalence of OSA than the general …

Effects of Weight Loss on Vascular Function in Obese Subjects

To evaluate the effect of weight loss on vascular function in obese with poor cardiovascular health. The investigators will evaluate the effects of weight loss on total and central body adiposity, blood pressure, central hemodynamic parameters, arterial stiffness, endothelial function, apnea-hypopnea index, insulin resistance and inflammatory markers.

Improving Outcomes for Patients With SDB and Insufficient Sleep

The purpose of this study is to look at how mild sleep disordered breathing (SDB), and not getting enough sleep each night, contribute to daytime sleepiness. The investigators also want to determine the treatment that works best for improving daytime sleepiness. In this study, the investigators are comparing 3 programs …
