Synergistic effects of short sleep duration and metabolic syndrome on major adverse cardiovascular events in older adults with obstructive sleep Apnea: A prospective cohort study.

Sleep medicine·July 1, 2026·PMID 41833185

Why it matters

OSA patients often have comorbid metabolic syndrome and short sleep, yet cardiovascular risk stratification typically focuses on apnea severity alone. This study highlights that the combination of poor sleep duration and metabolic dysfunction identifies a high-risk subgroup that may be missed by standard OSA metrics, suggesting a need for integrated sleep and metabolic assessment in clinical practice.
