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

Non-invasive left ventricular myocardial work identifies subclinical myocardial involvement in patients with systemic lupus erythematosus.
TL;DR: In this article , a non-invasive echocardiographic estimated left ventricular (LV) MW incorporating longitudinal strain curves and blood pressure data was evaluated in systemic lupus erythematosus (SLE) patients with normal LV ejection fraction (LVEF) by 2D-STI to reflect subclinical myocardial damage.

Impact of microbubble contrast on 2D strain quantification.

TL;DR: 2D strain measures were unaffected by the presence of Microbubble contrast, and reproducibility and the performance of the tracking algorithm were impaired when high intensities of MBC were present in the circulation.

Correlation of echocardiographic derived systolic time intervals in heart failure patients with other left ventricular systolic indices
TL;DR: It seems possible to get benefit from systolic time intervals in difficult conditions with poor windows and LV syStolic assessment is important as in therapeutic decision in heart failure patients.

TL;DR: Impaired predischarge DFR, regardless of the type of HF or predischarge systolic functional recovery, is an independent predictor of future MACE in HHF.

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.
