RV fractional area change was 48 ± 6% and tricuspid annular plane systolic excursion was 23 ± 3 mm. Total RV global longitudinal peak systolic strain (RVGLS total) was -21.5 ± 3.2%. Females had higher absolute RVGLS total (-22.3 ± 3.3 vs -20.7 ± 2.9%, p < 0.001) than males In a large meta-analysis including more than 2500 healthy volunteers (mean age 47±11 years, 51% male), the normal values of LV GLS ranged from –15.9% to –22.1% (mean 19.7%, 95% CI −20.4% to −18.9%). 7 Although all were healthy individuals, clinical characteristics (eg, age, gender, body mass index and blood pressure), as well as the vendor-specific software used for longitudinal strain analysis, may explain the variation in LV GLS. Results. The search identified 2,597 subjects from 24 studies. Reported normal values of GLS varied from −15.9% to −22.1% (mean, −19.7%; 95% CI, −20.4% to −18.9%). Normal global circumferential strain varied from −20.9% to −27.8% (mean, −23.3%; 95% CI, −24.6% to −22.1%).

For FT-CMR, GCS is more reproducible than GLS with similar normal values as STE. Radial strain shows large ranges between studies and variability of segmental strains remains too high to use them as single clinical measures. Strain gradient remained unchanged in age decades. Conclusion: Ageing shows an independent effect on GLS, LSsubendo, and, particularly on, LSsubepi.

Meta-regression showed LV end-diastolic diameter as a significant determinant of variation of longitudinal strain. Longitudinal systolic strain rate was significantly determined by age and radial strain was influenced by the type of vendor used analyse the influence of age on multilayer longitudinal strain and establish normal reference values of layer-specific strain according to age decades in a healthy population referring to our echo laboratory using 2D speckle-tracking echocardiography with layer-specific software. Normal reference of RV strain using CMR-TT.

Longitudinal strain. No unit. This is along the applied force.

Their LV systolic and diastolic functions were normal. RV fractional area change was 48 ± 6% and tricuspid annular plane systolic excursion was 23 ± 3 mm. Total RV global longitudinal peak systolic strain (RVGLS total) was -21.5 ± 3.2%. Females had higher absolute RVGLS total (-22.3 ± 3.3 vs -20.7 ± 2.9%, p < 0.001) than males 2017-01-01 Longitudinal strain is the deformation of the left ventricle in the z-direction that is from the base or annular ring to the apex usually resulting in a negative strain since the left ventricular chamber length (L) in systole is shorter than the respective length (L 0) at baseline in the normal heart 2,3.
