Traditional echocardiographic assessment of LV diastolic function relied on Doppler
patterns of mitral inflow. Reflecting the pressure gradient between the left atrium and LV …

Echocardiographic strain and strain rate imaging is a new technology enabling more
reliable and comprehensive assessment of myocardial function. The spectrum of potential …

Objectives: The aim of this study was to validate speckle tracking echocardiography (STE)
as a method for angle-independent measurement of regional myocardial strain, using …

Echocardiographic strain and strain-rate imaging (deformation imaging) is a new non-
invasive method for assessment of myocardial function. Due to its ability to differentiate …

Background—Tissue Doppler echocardiography–derived strain rate and strain
measurements (SDE) are new quantitative indices of intrinsic cardiac deformation. The aim …

Background—AL amyloidosis with heart failure is associated with decreased longitudinal
myocardial contraction measured by pulsed tissue Doppler imaging. We sought to clarify …

Objectives: We sought to determine whether disturbances of myocardial contractility and
reflectivity could be detected in diabetic patients without overt heart disease and whether …

Background Global left ventricular (LV) myocardial work efficiency, the ratio of constructive to
wasted work in all LV segments, reflects the efficiency by which mechanical energy is …

The echocardiographic assessment of regional myocardial function plays a critical role in
the diagnosis and management of ischemic heart disease and in most laboratories relies on …

Tissue Doppler (TDE), strain, and strain rate echocardiography are emerging real time
ultrasound techniques that provide a measure of wall motion. They offer an objective means …
