Abstract

Background: Contrary effects of vitamin B12 deficiency have been shown on the cardiovascular system. Aim of our study was to analyze left ventricular (LV) myocardial deformation, by using the two dimensional (2D) speckle tracking echocardiography (STE) in patients with vitamin B12 deficiency and normal LV ejection fraction.

Methods: Twenty-five patients with vitamin B12 deficiency (B12 levels < 200 pg/mL; meanage: 29.6 ± 8.2 years, 15 female), and 27 healthy controls (B12 levels > 200 pg/mL; meanage: 30.1 ± 6.9 years, 13 female) were included in the study. 2D echocardiography images were transferred to a workstation for further offline analysis. Longitudinal peak systolic (LPSS) and global strain (LGS) was obtained from 4 chamber and apical long axis (APLAX) views.

Results: Standard echocardiographic parameters and tissue Doppler imaging (TDI) velocities were compared between the groups. All LPSS values in the patient group except for apical 4C septal wall longitudinal strain were significantly decreased than those in the control group. There was a positive correlation between B12 levels and strain values except apical 4C septal wall strain values.

Conclusions: We found that in patients with vitamin B12 deficiency, global and segmental myocardial deformation was impaired and this impairment was correlated with the levels of vitamin B12.
