Reduced myocardial reserve in cirrhotic patients: an evaluation by dobutamine stress speckle tracking and tissue Doppler imaging (TDI) echocardiography

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

Dobutamine stress echocardiography and tissue synchronization imaging.

Dobutamine stress echocardiography has emerged as a reliable method for the diagnosis of coronary artery disease and the management of its treatment. Several studies have shown that that this technique works with 80-85% accuracy in comparison with other imaging methods. There are few studies aimed at developing the clinical utility of dobutamine stress echocardiography for the evaluation of nor...

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. ...

Tissue Doppler systolic velocity change during dobutamine stress echocardiography predicts contractile reserve and exercise tolerance in patients with heart failure.

AIMS Dobutamine stress echocardiography (DSE) is widely used to evaluate myocardial contractile reserve in patients with heart failure (HF). The aim of the study was to assess the relationship between the tissue Doppler (TD) mitral annulus systolic velocity (Sm) change during DSE, contractile reserve, and aerobic exercise capacity in HF patients. METHODS AND RESULTS Sixty-four HF patients (ag...

Tissue Doppler Imaging versus Conventional Echocardiography in Evaluation of Cardiac Functions in Diabetes Mellitus

Background: Conventional echocardiography and tissue Doppler imaging have been highlighted to diagnose diastolic and systolic heart dysfunction. We aimed to compare tissue Doppler imaging with conventional echocardiography to diagnose heart dysfunctions in diabetes mellitus type 1 (DMT1) patients. <s...
