Relation of Obstructive Sleep Apnea to Risk of Hospitalization in Patients with Heart Failure and Preserved Ejection Fraction From the National Inpatient Sample

Obstructive Sleep Apnea (OSA) increases the risk of diastolic dysfunction and heart failure. The impact of OSA on hospitalization for heart failure with preserved ejection fraction (HFpEF) is not well elucidated. We used data from the National Inpatient Sample (NIS) for the years 2012 to 2014. We identified discharges (age ≥18 years) associated with OSA and HFpEF using ICD-9-CM codes (327.23 and 428.3x) respectively. Propensity score analysis, adjusting for age, sex, race and comorbidities, compared the rates of admission for HFpEF in patients with OSA to those without OSA.
