Blood Markers to Better Understand and Treat Sleep Apnea

Researchers are looking for tiny molecules in blood called microRNAs that could serve as biomarkers—measurable signs—of obstructive sleep apnea. This study will collect blood samples from 500 people with moderate-to-severe sleep apnea and people without sleep apnea to see if microRNA patterns can help doctors identify the condition and predict who will benefit most from breathing treatment devices.

Currently, doctors have limited ways to identify sleep apnea or predict how well treatment will work for individual patients. Finding reliable biomarkers could make diagnosis easier, help monitor whether treatment is working, and show doctors which patients are most likely to benefit from specific therapies.
