The prevalence of Japanese pediatric hypertension is 0.9% based on proper measurement protocols. Hypertensive children tend to be hypertensive adults. Pediatric essential hypertension is characterized by an absence of symptoms, obesity, a family history of hypertension, and a low birth weight. The most common causes of pediatric secondary hypertension are renal parenchymal and renovascular diseases. Important factors controlling pediatric hypertension include healthy lifestyle modifications and pharmacotherapy. |
In children with primary dyslipidemia, functional myocardial abnormalities can occur at young age, including diastolic functional impairment of both ventricles and narrowing of the aortic valve and the sinus of Valsalva. Echocardiographic evaluations of high-risk children may be as important as biochemical evaluations. |
