RESUMEN
Cardiovascular disease (CVD) is the most important risk factor for morbidity and mortality in patients with chronic kidney disease (CKD). Aim of this study was to evaluate cardiac and vascular geometry in children with CKD stages 2, 3 and 4.Twenty-seven patients (18 males and 9 females) mean age 10.9 +/- 5.4 years with CKD and 30 children (control group) were enrolled with comparable age and sex. Weight, height, systolic and diastolic blood pressure were evaluated. We also analyzed biochemical assessments and proteinuria. We performed echocardiography with Philips iE33 and pulse wave velocity (PWV) with Vicorder PWS system. We documented significantly higher level of left ventricular mass index (LVMI) (30.3 +/- 7.6 g/m2.7) and PWV (4.7 +/- 1.6 m/sec) in CKD patients. Left ventricular hypertrophy (LVH) was present in 12 % and concentric remodelling in 36% of our patients. PWV values were significantly correlated with interventricular septal thickness (p<0.01) and with LVMI (p<0.05). In this study we documented the alterations of cardiac and vascular geometry since the early stages of CKD. PWV and echocardiographic measurements must be considered to assess cardiovascular risk in children with CKD stages 2-4.
