Timing of regional left ventricular lengthening by pulsed tissue Doppler.

TL;DR: The results show that pulsed tissue Doppler can identify a delayed and asynchronous initial wall lengthening in acute coronary syndromes.

TL;DR: Systolic myocardial strain agreed well with assessed wall motion and may be a new powerful tool to quantify regional wall contraction in patients with normal wall motion.

TL;DR: In this paper, the authors investigated the ability of non-invasive MW indices to identify the ischaemic risk area during transient acute coronary occlusion (TACO) and found a significant reduction of global longitudinal strain (GLS) (p = 0.005), MWI, MCW and MWE (p < 0.001) during TACO.

Function and mechanics of the left ventricle: from tissue Doppler imaging to three dimensional speckle tracking.
TL;DR: Three dimensional speckle tracking (3DST) has potential to be an ideal tool to assess not only global myocardial function but regional function through deformation, rotation, twist and untwisting parameters.
Journal ArticleDOI
Relationship between strain rate imaging and coronary flow reserve in assessing myocardial viability after acute myocardial infarction.
TL;DR: The degree of myocardial deformation determined by SR imaging was related to the degree of microvascular integrity determined by CFR, and can be used as a noninvasive method to predict myocardIAL viability after acute MI.

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.
