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 < 0.05). Compared with Group A, Group C showed decreased fractional shortening (FS), left ventricular ejection fraction (LVEF), deceleration time (DT), isovolumic relaxation time (IVRT), E/E' ratio, and peak filling velocity (FPV), as well as increased E and E' (p < 0.01). Compared with Group B, Group C showed decreased FS and increased E and FPV (p < 0.01).
CONCLUSION: In OSAHS patients with HFpEF and AF, cardiac remodeling and AF incidence are increased with the severity of OSAHS. OSAHS patients with HFpEF combined with AF have a significantly higher abnormality rate in right heart structural indices rather than left heart, mainly in the right atrium.
