Disentangling the role of obstructive sleep apnea in heart failure with preserved ejection fraction readmissions: a National Readmissions Database analysis.
BACKGROUND Obstructive sleep apnea (OSA) is highly prevalent among patients with heart failure with preserved ejection fraction (HFpEF). The aim of this study was to analyze the poorly characterized independent impact of OSA on short-term readmission and in-hospital outcomes among hospitalizations with HFpEF. METHODS...
