Standard Strain and Strain Rate by Two-Dimensional Speckle Tracking in Agoutis (Dasyprocta prymnolopha) Anesthetized with Ketamine and Xylazine

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 ...

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

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...

Feasibility and reference values of left atrial longitudinal strain imaging by two-dimensional speckle tracking

BACKGROUND The role of speckle tracking in the assessment of left atrial (LA) deformation dynamics is not established. We sought to determine the feasibility and reference ranges of LA longitudinal strain indices measured by speckle tracking in a population of normal subjects. METHODS In 60 healthy individuals, peak atrial longitudinal strain (PALS) and time to peak longitudinal strain (TPLS)...

Radial and longitudinal strain and strain rate assessed by speckle-tracking echocardiography in dogs with myxomatous mitral valve disease.

BACKGROUND Assessment of left ventricular (LV) function using conventional echocardiographic methods is difficult in mitral regurgitation (MR) owing to altered hemodynamic loading conditions. Newer methods such as speckle-tracking echocardiography (STE) provide assessment of LV strain (St) and strain rates (SR). HYPOTHESES Global St and SR are 1) decreased in dogs with clinical signs of conge...
