  Purpose

The purpose of this study is:

  1. To determine the frequency of cardiovascular diseases in patients with OSA, obese, overweight, and lean (BMI<25)
  2. To analyze the CPAP treatment over the clinical evolution of OSA patients
  3. To determine if OSA is a independent predictor of cardiovascular risk

Primary Outcome Measures:
  • Cardiovascular events [ Time Frame: five years ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 2000
Study Start Date: April 2005
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Detailed Description:

Obstructive Sleep Apnea (OSA) is a condition with important cardiovascular repercussions. However, the association between OSA, cardiovascular diseases, and obesity has not been totally clarified. We hypothesized that the cardiovascular consequences of OSA are due to obesity.
