Clinical Utility of Echocardiographic Strain and Strain Rate Measurements
TL;DR: Strain measurements have clinical utility in a number of settings and should be considered as part of the standard echocardiogram, such as subclinical LV dysfunction (e.g., GLS in HFpEF, stage B heart failure, aortic stenosis, mitral regurgitation), RV dysfunction (RV strain in pulmonary hypertension), atrial fibrillation (LA strain) and sequential follow-up (cardiotoxicity).

Evaluation of Coronary Artery Disease Using Myocardial Elastography with Diverging Wave Imaging: Validation against Myocardial Perfusion Imaging and Coronary Angiography.
TL;DR: Preliminary findings indicate that end-systolic radial strain measured with ME is higher on average in healthy persons than in CAD patients and that ME has the potential to be used for non-invasive, radiation-free early detection of CAD.

Myocardial velocities measured during adenosine, dobutamine and supine bicycle exercise: a tissue Doppler study in healthy volunteers
TL;DR: DSE quantified by tissue Doppler (TVI) have improved the diagnostic capacity of the procedure and are necessary for assessing any pathophysiological differences in different forms of stress.
Journal ArticleDOI
A preliminary study on the evaluation of relationship between left ventricular torsion and cardiac cycle phase by two-dimensional ultrasound speckle tracking imaging.
TL;DR: There is a temporal sequence difference of LVrot between basal and apical planes during LV contraction in heart failure group and decreased LVtor/rot have been demonstrated to influence left ventricular function.

TL;DR: An alternative approach, based on graphical techniques and simple calculations, is described, together with the relation between this analysis and the assessment of repeatability.

Myocardial Strain by Doppler Echocardiography Validation of a New Method to Quantify Regional Myocardial Function
TL;DR: Myocardial strain by Doppler echocardiography may represent a new, powerful method for quantifying regional myocardial function and is less influenced by tethering effects than Dopplers tissue imaging.
Journal ArticleDOI
Real-time strain rate imaging of the left ventricle by ultrasound
TL;DR: In the healthy hearts, a spatially homogeneous distribution of the strain rate was found and all the infarcted areas in this study showed up as hypokinetic or akinetic, demonstrating that this method may be used for imaging of regional dysfunction.

TL;DR: The concomitant enhancement of the myocardial Doppler signal after an intravenous injection of a transpulmonary echocardiographic contrast agent could permit the noninvasive assessment of regional myocardIAL perfusion.
