D-PO03-235 - Atrial Fibrillation Patients With Sleep Apnea Are More Likely To Have Diastolic Heart Failure (ID 379)

 J. Stepp: Nothing relevant to disclose.


Background: Sleep apnea increases oxidative stress and inflammation which leads to cardiovascular changes. Therefore, obstructive sleep apnea (OSA) may play a role in development of diastolic heart failure (DHF) in arrhythmia patients.
Objective: The objective of the study is to determine the association of OSA and DHF.
Methods: This is a retrospective observational study at an arrhythmia center. The study surveyed 74 arrhythmia patients presenting with dyspnea who underwent right heart hemodynamic testing with exercise.
Results: Patients with both OSA and AF were more likely to have DHF, p = 0.0241.
Conclusion: The severity of OSA is correlated to elevated PCW both at baseline and peak exercise, although was not clinically significant. Early diagnosis and treatment of OSA in AF patients may be helpful in the managment of DHF.
