TLDR
This multicenter study of nearly 250 volunteers without evidence of cardiovascular disease showed an average LV peak systolic strain of -18.6 +/- 0.1% and there was significant segmental variation of regional strain to necessitate the use of site-specific normal ranges.Abstract:
The interpretation of wall motion is an important component of echocardiography but remains a source of variation between observers. It has been believed that automated quantification of left ventricular (LV) systolic function by measurement of LV systolic strain from speckle-tracking echocardiography might be helpful. This multicenter study of nearly 250 volunteers without evidence of cardiovascular disease showed an average LV peak systolic strain of −18.6 ± 0.1%. Although strain was influenced by weight, blood pressure, and heart rate, these features accounted for only 16% of variance. However, there was significant segmental variation of regional strain to necessitate the use of site-specific normal ranges.read more

TL;DR: In asymptomatic patients with ≥3+ primary MR, non-dilated LV and preserved LVEF, LV-GLS is independently associated with exercise capacity, beyond known predictors.

TL;DR: Abnormal 2DLS was not clinically useful for excluding ACS in the ED even in patients with optimal 2D image quality, and lowQ echo is associated with worse2DLS.

Ultrasonic image analysis of longitudinal strain in uremic patients with preserved left ventricular ejection fraction.
TL;DR: Two-dimensional speckle-tracking echocardiography can identify LV myocardial abnormalities in uremic patients with preserved LVEF at early stage, as well as some changing regularities of LS and T-LS in the left ventricle.

TL;DR: RVAP appears to worsen global longitudinal strain more than RVSP, and the resultant decrease in apical strain is most correlated region to decrease in GLS.

Evaluation of the Transverse Oscillation Technique for Cardiac Phased Array Imaging: A Theoretical Study.
TL;DR: It is suggested that PWTO* improves lateral tracking performance, but only when interframe displacements remain relatively low, by translating findings into a clinical environment by suggesting optimal scanner settings.

TL;DR: In this paper, the authors assess the feasibility of 2D strain, a software for real-time quantitative echocardiographic assessment of myocardial function, which is based on the estimation that a discrete set of tissue velocities are present per each of many small elements on the ultrasound image.

TL;DR: The present study demonstrates the ability of Doppler echocardiography to measure myocardial strains in a clinical setting and may represent a new powerful method for quantifying left ventricular function noninvasively in humans.

TL;DR: SR/epsilon imaging appears to be a robust technique for quantifying regional myocardial deformation, and values describing radial deformation were higher than the corresponding SR/ep silon values obtained for longitudinal deformation.

TL;DR: Although myocardial velocities and strain rate showed significant dependence on age, displacement and peak systolic strain measures were less affected, and Doppler tissue echocardiography measurements showed a strong dependence on wall segment position.
