This study aims to determine the prevalence and prognosis of heart failure with preserved ejection function (HFpEF) among patients being assessed for sleep disordered breathing (SDB).
Patients with sleep disordered breathing (SDB) and those with heart failure with preserved ejection fraction (HFpEF) share similar characteristics. Increasing age, hypertension, obesity, diabetes mellitus and atrial fibrillation are well recognised links in both groups. It also known that SDB is common in patients with heart failure, both with reduced and preserved ejection fraction. It is therefore hypothesised that among patients being referred for SDB assessment, we can identify a group with unrecognised HFpEF.

Number of Participants With Unrecognised Heart Failure With Preserved Ejection Fraction (HFpEF) in Cohort With Clinically Suspected Sleep Disordered Breathing (SDB)
The diagnosis of HFpEF was established using criteria set out in the European Society for Cardiology (ESC) guidelines based on clinical symptoms and/or signs, biomarker analysis (NT-proBNP) and evidence of structural cardiac remodeling or diastolic dysfunction on transthoracic echocardiography.
