They can be rather easily assessed by conventional cardiac imaging modalities, most practically by M-mode or two-dimensional (2D) echocardiography, with adequate recognition of pitfalls. This study uncovers the impact of impaired renal function on left ventricular mass (LVM) and LVM index (LVMI) in children with CKD on regular hemodialysis (HD) attending the Zagazig University Hospital for Children. A total of 80 Egyptian children, out of which 40 subjects having a mean age of 11.2 \u00b1 3.12 years were cases with CKD in stage 5 on regular HD and the other 40 healthy subjects as controls, with a mean age of 12.2 \u00b1 2.54 years, were included in the study and assessed for LVH and LVMI by 2D echocardiography. HD children had a significantly higher mean LVMI (102.3 \u00b1 19.1 vs. 49.6 \u00b1 4.11 g\/m\n                    <jats:sup>2<\/jats:sup>\n                    ,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt;0.001) than controls. Relative wall thickness was significantly higher in the patients with CKD patients on HD compared with controls (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt;0.001) with a mean value of 0.46 indicating concentric LVH in renal patients. Comparing mitral inflow velocities between both the groups revealed that the patient group had a significant decrease in mitral E-wave velocity (0.88 \u00b1 0.2 vs. 1.1 \u00b1 0.1 m\/sec,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt;0.001) and E\/A velocity ratio (1.3 \u00b1 0.3 vs. 1.7 \u00b1 0.3,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt;0.001) in comparison with the control group, but there was no statistically significant difference in A-wave velocity. This indicates early diastolic dysfunction in CKD patients. LV mass changes in CKD children were strongly related to hypocalcemia and Vitamin D deficiency. Children with CKD are prone to the development of cardiac diastolic dysfunction and LVH, so early and regular echocardiographic studies of all children with CKD are recommended to detect early cardiac changes and institute interventions.\n
