Predicting cardiovascular events in sleep apnea

Obstructive sleep apnea generally is associated with increased risk for cardiovascular disease. Obstructive sleep apnea is usually measured using the apnea-hypopnea index, the number of times that breathing pauses or severely slows per hour of sleep. However, sleep studies using to diagnose obstructive sleep apnea produce a number of other measures. Whether those measures are associated with cardiovascular disease, and whether they predict cardiovascular disease as well or better than apnea-hypo...
