IMPACT OF OBSTRUCTIVE SLEEP APNEA IN PATIENTS HOSPITALIZED FOR HEART FAILURE WITH PRESERVED EJECTION FRACTION: A NATIONWIDE ANALYSIS

Previous studies showed obstructive sleep apnea (OSA) may worsen diastolic dysfunction in patients with heart failure with preserved ejection fraction (HFpEF). We aimed to quantify the impact of OSA on the in-hospital outcomes in patients admitted for HFpEF. We used the 2010 to 2014 National
