The study establishes age- and sex-stratified reference values for left atrial strain and strain rate in an Asian population, demonstrating that age and higher blood pressure are associated with mechanical functional decay.
Our findings suggest LA mechanical functional decays in association with increasing age and higher blood pressure, which seem to be compensated for by augmentation of atrial pump function. We have also provided age- and sex-stratified reference values for strain and SR based on a large-scale Asian population.
