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:

Detection of Left Ventricular Dysfunction by Global Longitudinal Systolic Strain in Patients with Chronic Aortic Regurgitation
Marit Kristine Smedsrud,Eirik Pettersen,Ola Gjesdal,Jan L. Svennevig,Kai Andersen,Halfdan Ihlen,Thor Edvardsen,Thor Edvardsen +7 more
TL;DR: The study demonstrated reduced global longitudinal strain in patients with chronic AR with preserved LV ejection fractions, which might disclose incipient myocardial dysfunction with a consequent potential for improved timing of aortic valve surgery.

Myocardial strain: can we finally measure contractility?
TL;DR: There existed a divine essence which was the life force of the heart, given the name “contractility,” the essence of the Essence of life, and in the discovery of “ contractility” lay the key … but how to discover it?
Journal ArticleDOI
Patients with a hypertensive response to exercise have impaired systolic function without diastolic dysfunction or left ventricular hypertrophy
TL;DR: An HRE is associated with subtle systolic dysfunction, even in the absence of resting HT, that occurs before the development of LV hypertrophy or detectable diastolic dysfunction and likely represent early hypertensive heart disease.

TL;DR: In patients with T2DM, current exercise recommendations led to an improvement in metabolic function, but failed to improve myocardial function in the overall group.

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.
