Abstract

Objectives: Vitamin D deficiency with its high global prevalence is associated with some pathological changes in the myocardium. The aim of our study was to assess the longitudinal deformation of the left ventricular (LV) myocardium in subjects with vitamin D deficiency. Methods: This cross-sectional study recruited 98 consecutive nondiabetic subjects (45 subjects with vitamin D deficiency and 53 subjects without vitamin D deficiency) without significant epicardial coronary artery stenosis. The longitudinal subendocardial deformation indices of the LV myocardium were evaluated with 2D speckle-tracking echocardiography. Results: The end-systolic strain, the systolic strain rate, and the early and late diastolic strain rates were not statistically significantly different between the subjects with and without vitamin D deficiency. Conclusions: 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. © 2018 Wiley Periodicals, Inc.
