Subclinical Alterations of Cardiac Mechanics Present Early in the Course of Pediatric Type 1 Diabetes Mellitus: A Prospective Blinded Speckle Tracking Stress Echocardiography Study

Figure 2

Speckle tracking echocardiography at rest in the apical 4-chamber view. (a) Peak systolic global LV longitudinal strain rate in a pediatric patient with type 1 diabetes mellitus. (b) Peak systolic global LV longitudinal strain rate in a healthy control subject. Dotted white line: global longitudinal strain rate, the coloured lines on the right correspond to the myocardial segments indicated on the left, dark green line at the bottom: ECG. Note the increased peak early systolic strain rate in the diabetic patient.
