Utility of home sleep apnea testing devices in patients with cardiac conditions—critical manual interpretation of the raw data is important

A recent study [1] published in this journal utilized the ApneaLink (ResMed) home sleep apnea testing (HSAT) device with a single channel (nasal airflow) to screen adult patients with stable chronic heart failure for sleep apnea. By design, the authors did not aim to distinguish between central sleep apnea (CSA) and obstructive sleep apnea (OSA). The data from the device was autoscored. HSAT using the above device and polysomnography (PSG) was performed simultaneously on the same night. The authors reported a “strong and significant correlation” between the apnea hypopnea index (AHI) determined by ApneaLink and the AHI determined by PSG. Based on the above results, the authors suggest that ApneaLink could be used to identify heart failure patients with sleep apnea and thus in their opinion, relegate the need for a PSG in such patients, which they feel will provide a more cost-effective and timely diagnosis.
