Abstract Objective To explore the cardiac structural and functional changes in obstructive sleep apnea-hypopnea syndrome (OSAHS) patients with heart failure with preserved ejection fraction (HFpEF) and atrial fibrillation (AF). Methods This retrospective study included 336 OSAHS patients with HFpEF. They were divided into Groups A (without an AF history and no AF episodes during cardiac color ultrasound examination), B (an AF history but no AF episodes), and C (an AF history and AF episodes). They all received cardiac color ultrasound examinations. Cardiac structural and functional changes in ultrasonic cardiograms were compared between the three groups. Results Compared with Groups A and B, Group C showed increased left atrial diameter (LAD), left atrial volume (LAV), right ventricular diameter at end-diastole (RV-D1), right ventricular diameter at end-systole (RV-D2), right ventricular outflow tract diameter (RVOT2), right atrial diameter at end-diastole (RA-D1), right atrial diameter at end-systole (RA-D2), and right atrial area (RAA) (p
