Introduction:

There is a close relationship between chronic kidney disease (CKD) and cardiovascular disease. One of its clinical manifestations is left ventricular hypertrophy (LVH), expressed as Left Ventricular Mass Index (LVMI gr/m27). In CKD patients with growth retardation, the LVMI calculation should be adjusted by correcting age for length/height.

Objective:

To compare the age-corrected LVMI for length/height with the value calculated by chronological age in CKD children on dialysis.

Patients and Method:

Cross-sectional study. We analyzed echocardiographies of CKD children on dialysis aged between 1 and 18, from January 2016 to July 2017. LVMI was evaluated by adjusting the value expressed in gr/m27 to the percentile for the chronological child’s age, and then the value was adjusted to the age-corrected length/height. We used descriptive statistics and concordance study for LVMI assessments calculating by chronological age and for age-corrected length/height.

Results:

26 patients were included and 75 echocardiograms. 56% had left ventricular hypertrophy using chronological age versus 46.6% age-corrected LVMI for length/height. When comparing the percentile groups of LVMI-chronological age vs. age-adjusted LVMI for actual length/height, it was observed that 18.6% of the sample changed percentile groups, 100% of them to a lower percentile group. The agreement evaluated based on the Kappa coefficient was 0.72 (perfect agreement > 0.8), confirming differences when adjusting the LVMI for age-corrected length/height.

Conclusion:

Calculating LVMI by chro nological age overestimates the cardiovascular involvement in children with CKD who are charac teristically stunted. The results suggest that the age-adjusted, length/height-corrected calculation of LVMI gives greater accuracy to the diagnosis of left ventricular hypertrophy in this group of patients.
