Prediction of infarct size by speckle tracking echocardiography in patients with anterior myocardial infarction.

Background: Speckle tracking echocardiography (STE) is based on tracing of pixel groups in grayness scale for the quantitative measurement of myocardium strain and myocardium strain rate. Recent data suggest that evaluation of STE could be a tool for myocardial function assessment similar to MRI.

Aim: To assess the predictive value of STE for the evaluation of infarct size in patients with anterior ST-elevation myocardial infarction (STEMI).

Assessment of left ventricular function with computed tomography and magnetic resonance in patients with low ejection fraction scheduled for coronary artery bypass grafting: a preliminary study.

Introduction: Reliable estimation of left ventricular (LV) parameters with the use of computed tomography (CT) has not been verified in patients with low ejection fraction (EF) so far.

Objectives: The aim of this preliminary study was to assess the agreement between magnetic resonance imaging (MRI) and CT in the assessment of the LV volume and EF in patients with low EF scheduled for coronary artery bypass grafting (CABG).

Patients And Methods: In 18 patients (2 women, 16 men) with the EF of 40% or lower scheduled for CABG, cardiac 1.
