Cardiac disease in children with mild-to-moderate chronic kidney disease

Area of Science:

• Pediatric Nephrology
• Cardiology
• Cardiovascular Complications of CKD

Background:

• Cardiovascular complications are a major concern in chronic kidney disease (CKD).
• Pediatric CKD offers a unique model to study cardiovascular disease mechanisms without confounding factors like aging and diabetes.
• Echocardiography is a key tool for assessing cardiac structure and function.

Purpose of the Study:

• To review recent echocardiographic studies on left-ventricular mass, geometry, and function in children with mild-to-moderate CKD.
• To understand the prevalence and characteristics of cardiac abnormalities in pediatric CKD.
• To identify factors associated with cardiac changes in this population.

Main Methods:

• Review of recent echocardiographic studies in pediatric populations with CKD stages 2-4.
• Cross-sectional assessment of a large pediatric cohort.
• Analysis of left-ventricular mass, geometry (concentric vs. eccentric), and systolic function.

Main Results:

• Prevalence of left-ventricular hypertrophy (LVH) is 33% in children with CKD stages 2-4.
• Concentric and eccentric LVH occur with equal frequency, indicating diverse underlying mechanisms.
• Concentric LVH is linked to systolic dysfunction; LV mass and dysfunction correlate inversely with glomerular filtration rate.
• Obesity, anemia, and inflammation are associated with LVH, while blood pressure shows minimal association.

Conclusions:

• Children with early CKD exhibit significant cardiac abnormalities, highlighting an intrinsic cardiovascular impact.
• Regular echocardiographic screening is recommended for pediatric patients with CKD to detect and manage cardiac changes.
• Findings underscore the importance of early cardiovascular risk assessment in pediatric CKD.
