Cardiovascular disease in children with chronic renal failure.

Cardiovascular disease (CVD), including atherosclerosis, hypertension, myocardial infarction, and cerebrovascular accidents, constitutes an important cause of morbidity and mortality in adults with chronic kidney disease (CKD). However, evidence has been accumulating over the past several years that children and young adults with CKD also experience significant cardiovascular complications. Studies in the United States and Europe have shown that CVD is a leading cause of death in young adults diagnosed with CKD in childhood. Risk factors include hypertension, dyslipidemia, anemia, and abnormal calcium-phosphorus metabolism, all of which are present in many children with CKD. Although improved control of uremia and treatment of traditional and nontraditional cardiovascular risk factors have proved to be beneficial in adults with CKD, no such data exist for children. The NIH is currently conducting a large-scale, prospective observational study of children with CKD that should help to elucidate the role of CVD in the progression of CKD in children and what interventions might reduce the risk of cardiovascular complications in these young patients.
