3.3. 2D-Speckle Tracking Echocardiography
Global longitudinal strain values
based on all three apical views (A4C, A2C, A3C) and total global strain
values did not appear to be different between the
patient and the control group
(p=0.59, p=0.51, p=0.15, p=0.38; Table 2). LV longitudinal myocardial
strain measurements indicated the following reductions in the following
parameters: A2C basal inferior and basal anterior, and A3C mid
inferolateral. Circumferential strain rate measurements were not
different between the patient and the control group (p = 0.68). However,
there were significant differences between the normotensive CoA subgroup
and hypertensive CoA subgroup, with respect to 2D-STE longitudinal
myocardial deformation properties in some segments of the LV walls (p
< .05; Table 3).
