Abstract
The lifespan of children with advanced chronic kidney disease (CKD) remains low compared with the general pediatric population. As in adults with CKD, cardiovascular disease accounts for the majority of deaths in children with CKD, as these patients have a high prevalence of traditional and uremia-related risk factors for cardiovascular disease. The cardiovascular adaptations that precipitate these terminal events begin in predialysis CKD. Initially, these alterations increase left ventricular performance and vascular function to maintain hemodynamic homeostasis. However, these modifications are unable to sustain cardiovascular function in the long term and ultimately lead to left ventricular failure, impaired cardiorespiratory fitness and even sudden death. In this Review, we provide an update on the prevalence of the risk factors associated with cardiovascular disease in pediatric patients with CKD, the cardiac and vascular adaptations that occur in these patients and the management of cardiovascular risk in this population.
Key Points
-
Cardiovascular disease is the major cause of death in young patients with childhood-onset chronic kidney disease (CKD)
-
Similar to adults with CKD, children with CKD have a high prevalence of traditional and CKD-related risk factors for cardiovascular disease
-
Cardiovascular abnormalities develop early in the course of CKD and progress as the end stage approaches
-
Left ventricular hypertrophy, increased carotid artery intima–media thickness and cardiac calcification are the most frequent early cardiovascular abnormalities in children with CKD
-
Pre-emptive kidney transplantation or intensified hemodialysis are key to the reduction of cardiovascular morbidity and mortality in children and young adults with CKD
