Assessment of regional myocardial systolic function in hypertensive left ventricular hypertrophy using harmonic myocardial strain imaging
TL;DR: Myocardial systolic impairment in hypertensiveleft ventricular hypertrophy may occur from the endocardium side, and the impairment may progress with increased left ventricularhypertrophy.

TL;DR: Patients with baseline symmetric tethering patterns showed more extensive abnormal strain, which was observed in all LV segments and was not reverted by surgery, and these findings require confirmation in additional larger studies.

Quantitation of Papillary Muscle Function with Tissue and Strain Doppler Echocardiography Measures Papillary Muscle Contractile Functions
TL;DR: Tissue velocity, strain rate, and strain values were found decreased in dysfunctional papillary muscle, and there were no significant differences with respect to Sm, SR, and S measured from the two points.

TL;DR: Left ventricular (LV) global strain along its long axis during systole, which is obtained by dividing mitral annular excursion by the distance from the mitralannulus to the LV apex at end-diastole, can be used to assess whole LV systolic performance.

Statistical methods for assessing agreement between two methods of clinical measurement.
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.
