TLDR
The new SDE approach might be a more accurate marker than TDE for detecting systolic regional myocardial dysfunction induced by LAD occlusion and reduced velocities in all septal segments during angioplasty.About:

Diagnostic accuracy of left ventricular longitudinal function by speckle tracking echocardiography to predict significant coronary artery stenosis. A systematic review
TL;DR: GLS measurements at rest only have modest diagnostic accuracy in predicting CAD+ among patients presenting with acute or chronic chest pain, and results from regional strain, layer specific strain and DSE need to be verified in larger studies.
Journal ArticleDOI
Abnormal Right Ventricular Myocardial Strain Generation in Mild Pulmonary Hypertension
TL;DR: Mild elevations in PASP affect the mechanical properties of the RV and result in RV dyssynchrony despite absence of gross abnormalities in RV size or function.
Journal ArticleDOI
Comparison of the strain Doppler echocardiographic features of familial amyloid polyneuropathy (FAP) and light-chain amyloidosis.
TL;DR: Strain and strain-rate imaging, sensitive markers of longitudinal systolic dysfunction, might detect a difference in left ventricular function between FAP and light-chain amyloidosis that could account for the clinical differences.

Strain rate analysis allows detection of differences in diastolic function between viable and nonviable myocardial segments

TL;DR: Dys-synergic viable myocardial segments demonstrate an increase in E and A waves SR with dobutamine stimulation whereas nonviable segments are less responsive to dobutamines.
Journal ArticleDOI
Normal left ventricular ejection fraction and mass but subclinical myocardial dysfunction in patients with Friedreich's ataxia
TL;DR: Evidence of morphological and functional abnormalities in FRDA patients with normal LVEF and mass is found and this decreased LV pump performance was associated with a concentric remodelling pattern.

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.
