Why the study?
LA size and function are important prognostic imaging biomarkers, but normal values and age- and gender-dependency of 3DSTE-derived LA strains in healthy subjects needed to be defined.
Population
222 healthy subjects (mean age 36.3 ± 13.7 years, 112 males)
Comparison
Assessment of 3DSTE-derived LA strains stratified by age and gender
Design
Cross-sectional study

Supports age- and sex-specific 3DSTE LA strain references in healthy adults; leaves open validation in clinical populations.
This study establishes normal reference values and age- and gender-dependencies for 3DSTE-derived left atrial strain parameters, providing a baseline for identifying pathological left atrial dysfunction.
