BackgroundLeft ventricular hypertrophy (LVH) is associated with a premature death in children with chronic kidney disease (CKD). We studied its change over time, related to a successful kidney transplantation (KTx) and assessed whether clinical variables were associated with the left ventricular mass index (LVMI).MethodsWe obtained the records of all children and adolescents, who were followed-up at the tertiary nephrology centre for children at the Children's University Hospital in Kosice, Slovakia, during 2008-2014, had completed echocardiographic studies while on chronic dialysis and had undergone a successful KTx, n=25. We assessed the longitudinally recorded left ventricular mass index (LVMI) and the presence/absence of LVH, and risk factors for LVH.ResultsThe average prevalence of LVH was 23.5 % while on dialysis, and 29.4 % after KTx (p=0.06). Pre-post changes per patient were relatively big. Uncontrolled systolic hypertension was significantly related to LVMI (p=0.03).ConclusionLVH is common after paediatric KTx and the reversibility of already present LVH seems to be rather problematic. Significant changes of LVMI on the individual level suggest that modification is feasible with a thorough control of (systolic) hypertension and of the other risk factors (Tab. 3, Fig. 1, Ref. 50).
