Linz D, et al. - This study was undertaken to determine the link between different measures of sleep-disordered breathing (SDB) severity and epicardial fat volume (EFV) after acute myocardial infarction (MI). In this work, it was demonstrated that in patients with acute MI, the hypoxia load representing the integrated area of desaturation divided by total sleep time (HL_TST), a novel parameter to determine nocturnal hypoxemic burden, and not apnea-hypopnea index as an event-based measure of SDB, was related to EFV.
