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

Does the transapical approach impair early recovery of systolic strain following transcatheter aortic valve replacement
TL;DR: Equal improvement in myocardial strain was observed in the TF and TA patients, highlighting how it is the patient's baseline GLS dysfunction, not the method of approach, that dictates post-TAVR functional recovery.

TL;DR: Speckle tracking‐based GLS is feasible and reproducible in pediatric heart recipients and is reduced at baseline, and the role of GLS and BNP in detecting early systolic dysfunction warrants further investigation.

Role of global longitudinal strain in assessment of left ventricular systolic function in patients with heart failure with preserved ejection fraction.
TL;DR: There is significant left ventricular systolic impairment detected by GLS despite preserved LVEF, and the value of left ventricle (LV) GLS was significantly impaired in the HFpEF group despite normal LVEf.

TL;DR: In a sample of the general population, VFA, but not SFA, accumulation was significantly associated with decreased LV and RV strain, an association that may be involved in the increased risk of HF in obese individuals.

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.
