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: Patients with chronic Chagas disease and normal global and segmental LV systolic function on two-dimensional echocardiography had global and segmentsal LV ε similar to that of control subjects, however, those in the early stages of the cardiac form and cardiac fibrosis had lower global longitudinal, circumferential, and radial LVε.

TL;DR: Intervendor agreement in GLS and regional strain measurements have significantly improved after the EACVI/ASE Task Force Strain Standardization Initiatives, however, significant wide LOA still exist, especially for local strain measurements, which remains relevant when considering vendor-specific software for serial measurements.

TL;DR: LV function improved after replacement of a stenotic aortic valve demonstrated by improved longitudinal strain rate, in contrast, RV function, assessed by longitudinal strain, was reduced.

TL;DR: Speckle tracking echo is a useful clinical tool to distinguish differential RV contractility between PAH subtypes and these findings were shown in a cross-sectional analysis of asymptomatic SSc patients without symptomatic RV failure, right heart catheterisation-confirmed PAH or with echocardiographic evidence of RV dilatation.

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.
