Assessment of strain and strain rate by two-dimensional speckle tracking in mice: comparison with tissue Doppler echocardiography and conductance catheter measurements

myocardial strain and strain rate imaging: comparison between doppler derived strain imaging and speckle tracking echocardiography

Evaluation of strain and strain rate parameters using two-dimensional speckle-tracking echocardiography in patients with coronary artery disease (Research Article)

The study aimed was to measure left ventricular (LV) strain using speckle tracking echocardiography (STE) for assessment of LV function. Eighty-two subjects (mean age 57±9 years) with suspected chest pain underwent two-dimensional (2D)-echocardiography before coronary angiography. Conventional echocardiographic parameters were used for the assessment of LV function. Longitudinal strain and its ...

Comparison of apical left ventricular segments strain imaging by tissue Doppler and speckle tracking echocardiography.

BACKGROUND Spatial orientation of left ventricular (LV) apical segments is a potential limitation to assessment by tissue Doppler echocardiography (TDE). Speckle tracking echocardiography (STE) is a recently developed quantification technique and has the advantage of being angle-independent as compared to TDE. AIM To assess matching apical segments' longitudinal strain data from TDE and STE. ...

Left ventricular strain and strain rate by two-dimensional speckle tracking echocardiography in patients with subclinical hypothyroidism.

AIM Subclinical hypothyroidism (SH) is an asymptomatic condition defined by increased serum thyroid-stimulating hormone (TSH) with normal free thyroid hormone levels. Heart is a major target organ for thyroid hormone action. The aim of this study was to evaluate cardiac functions in patients with SH by speckle tracking imaging. PATIENTS AND METHODS We included 23 consecutive patients with unt...

Comparison of two-dimensional speckle and tissue Doppler strain measurement during dobutamine stress echocardiography: an angiographic correlation.

AIMS Two-dimensional (2D)-strain derived from speckle-tracking is an alternative to tissue velocity imaging (TVI)-based strain. We compared their feasibility and accuracy in 150 patients undergoing dobutamine stress echocardiography (DSE) and coronary angiography. METHODS AND RESULTS 2D- and TVI-strain were obtained in three apical views at rest and peak stress. Peak systolic strain rate (SR)...
