What are the echocardiographic reference ranges of global longitudinal strain for all cardiac chambers using guideline-directed dedicated views?
Age and sex significantly influence echocardiographic reference ranges of global longitudinal strain and must be considered when interpreting strain echocardiography.
Reference ranges of strain for all cardiac chambers were established based on guideline-directed chamber-specific recordings. Age and sex were the most important factors influencing reference ranges and should be considered when using strain echocardiography.
Nyberg et al. (2023) studied this question.
