Does longitudinal AFI global and segmental strain offer better reproducibility compared to 2D left ventricular volumes and ejection fraction?
Global longitudinal peak systolic strain (GLPSS) demonstrates excellent reproducibility that is superior to 2D ejection fraction, making it highly suitable for assessing LV systolic function.
Overall, reproducibility of GLPSS is excellent and superior to that of 2D EF, whereas segmental LPSS reproducibility is good and similar to that of LV volumes. Both are suitable for diagnosis and follow-up of LV global and regional systolic function.
