Impact of acute hyperglycemia on layer-specific left ventricular strain in asymptomatic diabetic patients: an analysis based on two-dimensional speckle tracking echocardiography

An example of a color-coded two-dimensional speckle tracking echocardiography (2D-STE) of the left ventricle (LV) and corresponding time–strain curves from 18 LV segments derived from the apical 4-, 2-chamber and long-axis views for measurement of global longitudinal strain (GLS) in diabetic patient with acute hyperglycemia. GLS was calculated as the average peak strain of 18 LV segments, and in this example the value of GLS is ？？22.4
