Event-Weighted Desaturation Burden and Cardiovascular Mortality in Sleep Apnoea: Findings from a Large Community-Based Prospective Cohort.
European journal of preventive cardiology·October 12, 2026·PMID 42860838
Why it mattersSleep apnea severity is typically assessed by AHI, which may not capture the full cardiovascular stress of disordered breathing. EWDB integrates event intensity, cumulative hypoxic burden, and regularity, potentially offering a more physiologically meaningful predictor of cardiovascular risk in sleep clinic and cardiology populations.
