BACKGROUND: @entity65 remains the most common cause of mortality in @entity740 ( @entity740 ). METHODS: In this cross-sectional study, 43 pediatric @entity1 with @entity740 were divided into two groups according to their estimated glomerular filtration rate (eGFR): groups 1 and 2 (eGR; 29-75 and 15-29   mL/ @entity1009 .73   m(2), respectively). M - mode, conventional pulsed wave Doppler (cPWD) echocardiography and tissue Doppler imaging (TDI) were performed in all @entity1 and 16 healthy controls. Maximal early (E wave) and late (A wave) diastolic flow velocities were assessed by cPWD. Using TDI, the early (E') and late (A') diastolic filling velocities were recorded. Early and late diastoles were evaluated using E' values and E/E' ratios, respectively. RESULTS: @entity4346 ( @entity4346 ) was determined in 19/43 (44.2%) @entity1 . The E/E' ratio was significantly higher in group 2 than in group 1 and controls. E/E' was found to be positively correlated with @entity1002 ( @entity1002 ) index, and negatively with hemoglobin (Hb) levels. Low Hb levels were only independent predictor of E/E' (p   =   0.001, b: -0.470, 95% CI: -0.764; -0.196). E' ratio was significantly lower in both @entity1 groups compared to the controls. CONCLUSIONS: @entity4346 and @entity67 are already present in early stages of @entity740 . Treatment of risk factors, such as @entity417 , is important to improve the clinical outcome.
