Effects of PAP Treatment of OSA in Patients With Heart Failure (OSA-MRI)
The purpose of this study is to see if treatment of OSA with the CPAP device makes a difference to insulin resistance and heart disease.
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label

Obstructive Sleep Apnea (OSA) has been seen frequently in persons who develop insulin resistance and heart disease. Insulin resistance is a condition in which the body produces insulin but does not use it properly. Insulin helps the body use glucose for energy. Insulin resistance increases the chance of developing type II diabetes and heart disease.
One method of treatment for OSA is with continuous positive airway pressure (CPAP). This treatment is given by a device named CPAP. There are many different types of CPAPs available on the market that are FDA approved.
The purpose of this study is to see if treatment of OSA with the CPAP device makes a difference to insulin resistance and heart disease. This study will measure insulin resistance by testing the glucose level in the blood, and testing the levels of special protein found in blood, that are known to increase the sensitivity to insulin and decrease progression of heart disease. The heart disease will be measured by cardiac MRI. Glucose testing and cardiac MRI's are normal testing procedures for people who have OSA and heart disease, however will be conducted more frequently than normal and therefore are for research purposes. The specialized blood testing is for research purposes only.
