Evaluation of hypertension in children.

Hypertension is an important public health problem, and increasingly children are being diagnosed with primary hypertension. As the list of secondary causes of hypertension is extensive, pediatric practitioners increasingly need to decide on investigations needed for evaluating children presenting with high blood pressure. The differentiation between primary and secondary hypertension is paramount to understanding this important health issue, since many forms of secondary hypertension require specific treatment. The review evaluates the current available guidelines and practice patterns for evaluating children with elevated blood pressure. The review also aims to provide a framework for cost-effective evaluation strategies for children with elevated blood pressure based on current recommendations and evidence.
