[Echocardiographic findings in children with chronic renal failure ]
Insights
Children with chronic renal failure not on hemodialysis showed normal cardiac function. However, those on chronic hemodialysis exhibited myocardial hypertrophy and reduced contractility, with no changes post-treatment.
Area of Science:
- Pediatric Cardiology
- Nephrology
- Cardiovascular Research
Background:
- Chronic renal failure (CRF) in children can impact cardiovascular health.
- Understanding the cardiac effects of CRF and its treatments is crucial.
Purpose of the Study:
- To evaluate cardiac function in children with CRF, comparing those on and off hemodialysis.
- To assess the impact of chronic hemodialysis on myocardial structure and contractility.
Main Methods:
- Echocardiographic examinations were performed on two groups of children with CRF (n=9 each).
- Group 1: Children with CRF not on hemodialysis.
- Group 2: Children with CRF undergoing chronic hemodialysis.
- Comparison with a control group of 35 healthy children.
Main Results:
- Children not on hemodialysis showed no cardiac differences compared to controls.
- Children on chronic hemodialysis exhibited moderate myocardial hypertrophy and left atrial dilatation.
- Contractility indices were decreased in the hemodialysis group.
- No significant changes in cardiac function were observed before and after hemodialysis sessions.
Conclusions:
- Chronic hemodialysis in children with CRF is associated with adverse cardiac remodeling and impaired contractility.
- Hemodialysis itself does not appear to acutely alter cardiac function.
- Further research into managing cardiovascular complications in pediatric CRF is warranted.
Abstract:
Echocardiographic examinations were carried out in 2 groups of children with chronic renal failure. Group 1 consisted of 9 children who were not treated with hemodialysis. Group 2 consisted of 9 children undergoing chronic hemodialysis. Results in both groups were compared with a control group of 35 normal children. No difference was found between normal children and group 1 children. Group 2 children presented with a moderate myocardial hypertrophy and dilatation of the left atrium. Indices of contractility were also decreased. Comparison before and after hemodialysis showed no change in cardiac function.
