Is the longitudinal deformation of the left ventricle affected by vitamin D deficiency in nondiabetics? A 2D speckle-tracking echocardiographic study.

The global longitudinal subendocardial deformations of the LV, including the systolic strain rate and the systolic and diastolic strain rates, as evaluated with 2D speckle-tracking echocardiography were not statistically significantly correlated with the presence or absence of vitamin D deficiency.
