LA volumetric parameters and LA global strain
The mean maximum indexed LA volume (LAVi) was 22.2 ± 6.8 ml/m2. The reservoir and contractile LA functions were the most altered with respect to normal population values. The mean peak atrial longitudinal strain at the reservoir phase for the total population was 29.2 ± 8.9%, with a prevalence of abnormal PALS of 58.8% (95% CI : 50.0 – 68.6).
