Tissue Doppler imaging suggests an association between endotoxemia and impaired myocardial relaxation

Detecting impaired myocardial relaxation in sepsis with a novel tissue Doppler parameter (septal e′/s′)

BACKGROUND Left ventricular diastolic dysfunction is associated with mortality outcomes in severe sepsis and septic shock. There are ongoing issues with diagnosing diastolic dysfunction in this cohort, partly owing to the poor applicability of traditional parameters in the hyperdynamic circulation. In this feasibility study, we sought to assess the utility of a novel parameter (septal e'/s') to...

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

Hypercholesterolemia and Myocardial function evaluated via Tissue Doppler Imaging

OBJECTIVE To establish a link between hypercholesterolemia and myocardial dysfunction. BACKGROUND Heart failure is a complex disease involving changes in systolic and diastolic function. Newer echocardiographic imaging modalities may be able to detect discreet changes in myocardial function associated with hypercholesterolemia. Therefore we sought to establish a link between hypercholesterole...

Doppler Tissue Imaging in St-elevation Myocardial Infarction

Highly available, noninvasive and cost-effective, echocardiography remains a keystone in the evaluation of patients with coronary artery disease (CAD). Echocardiographic assessment of cardiac function at rest and during dobutamine stress has direct clinical implications. Conventional echocardiographic parameters however, are partly based on visual interpretation of cardiac motion, thereby subje...

Disagreement between tissue Doppler imaging and conventional pulsed wave Doppler in the measurement of myocardial performance index.

AIM Myocardial performance index (MPI) is usually measured with pulsed wave Doppler (PWD). Our aim was to assess the degree of agreement between PWD and a method based on tissue Doppler imaging (TDI). METHODS AND RESULTS Seventy-five patients with prior myocardial infarction and 20 healthy subjects underwent measurement of time intervals and MPI with PWD and pulsed TDI at septal and lateral s...
