Results: : A total of 767 participants were included in analyses, after
unreadable artifacts were excluded. At least one type of cardiac rhythm
disturbance (atrial or ventricular arrhythmia and/or pause) was found in
62.7% of them, and OSA in 35.9%. Both ventricular and atrial arrhythmia
were 6 times more frequent among severe OSA individuals than
controls (92.3% vs. 53.3% and 85% vs. 47%, respectively; p 30; 32% at CC; 29% at JHH).
Cardiac surgery patients with severe SDB stayed in the ICU longer than
those without SDB (0.7 days longer at CC, 1.1 days longer at JHH).
More detailed analysis of outcome data is underway.
Conclusion: While the results are preliminary, this study shows that
SDB is common in patients undergoing cardiac surgery procedures and
may lead to extended ICU stay. The study also confirms the feasibility
and quality of pre-operative PSG recorded in the hospital and monitored
remotely.
Support (If Any): Support for this research was provided by a grant
from the National Institute of Neurological Disorders and Stroke, National
Institutes of Health.

Introduction: Obstructive sleep apnea (OSA) is common in coronary
artery disease (CAD) and a possible cause of increased mortality. To
date, there is a lack of randomized controlled trials to draw the conclusion
that all CAD patients should be investigated for OSA and subsequently
be treated with continuous positive airway pressure (CPAP).
The RICCADSA study is an on-going Swedish single-center (two sites)
trial started in December 2005 addressing the impact of CPAP in newly
revascularized CAD patients and concomitant OSA (Apnea-Hypopnea-
