Comparison of control and type 1 diabetic animals assessing systolic radial velocity, radial strain, and radial strain rate between free wall and septal wall segments of the LV within a given week (A–F). Values are means ± SEM; *P < 0.05 as compared to control within a given week. Open bars = Control animals, n = 8; Closed bars = Diabetic animals, n = 8. Septal wall segments include the anterior base, anterior mid, and anterior apex. Free wall segments include the posterior base, posterior mid, and posterior apex.
