Comparison of left atrial (LA) mechanical parameters. LA emptying fraction (LAEF) (A), left atrial strain during reservoir phase (LASr) (B), left atrial strain during conduit phase (LAScd) (C), and left atrial strain during contraction phase (LASct) (D) were compared between heart failure with preserved ejection fraction (HFpEF) with global longitudinal strain (GLS) ≥ median and controls, and between HFpEF with GLS < median and controls. The central horizontal line represents the mean of each group with 95% confidence interval. A p-value of less than 0.05 indicates a statistically significant difference between the means of each group
