Studies with school aged children of several communities of the United States have indicated that between one and two percent of them should be considered hypertensive. These findings contradict previous statements of a very rare incidence of hypertension in childhood. Some studies show that children of Black and Hispanic American ancestry, especially females, have a higher incidence of hypertension. The highest incidence of hypertensive children was related to a history of familial hypertension and obesity. In children less than three years of age and in infants, hypertension is less frequent. A disease of the urinary apparatus (nephropathy) or of the cardiovascular system (aorta coarctation) can often be identified as the primary cause of the hypertension. Less frequent is hypertension sustained by adrenal cortical dysfunction or a neoplasm of the adrenal medulla. Hypertensive crisis also frequently develops in children after thermal injury or renal transplant. In children, the use of antihypertensive drugs should be reserved for cases where the disease is very severe. Effective regulation of dietary and hygienic habits should be recommended, particularly for those cases of "mild" or "borderline" essential hypertension.

Systemic arterial hypertension in children has traditionally been thought to be secondary in origin. Increased incidence of risk factors like obesity, sedentary life-styles, and faulty dietary habits has led to increased prevalence of the primary arterial hypertension (PAH), particularly in adolescent age children. PAH has become a global epidemic worldwide imposing huge economic constraint on health care. Sudden acute increase in systolic and diastolic blood pressure can lead to hypertensive crisis. While it generally pertains to secondary hypertension, occurrence of hypertensive crisis in PAH is however rare in children. Hypertensive crisis has been further subclassified depending on presence or absence of end-organ damage into hypertensive emergency or urgency. Both hypertensive emergencies and urgencies are known to cause significant morbidity and mortality. Increasing awareness among the physicians, targeted at investigation of the pathophysiology of hypertension and its complications, better screening methods, generation, and implementation of novel treatment modalities will impact overall outcomes. In this paper, we discuss the etiology, pathogenesis, and management of hypertensive crisis in children. An extensive database search using keywords was done to obtain the information.
