Primary Hypertension in Children and Adolescents: Risk Factors and Vascular Damage

Abstract

The incidence of primary hypertension is on the rise in the pediatric population, with an approximate prevalence ranging from 3% to 5%. The most significant risk factors for the onset and development of primary hypertension are well-known, and some of them are preventable, including increased salt consumption and obesity. Connected with metabolic risk factors, elevated blood pressure in childhood is carried into adulthood. Primary hypertension is associated with attenuated vascular responses to various physiological stimuli in both peripheral microcirculation and systemic macrocirculation in adults and children. Endothelial dysfunction is one of the most important features of arterial hypertension, together with an increased level of oxidative stress – both determinants significantly contribute to all the pathophysiological changes observed in hypertension. Systemic arterial hypertension has emerged as a prevalent cardiovascular risk factor associated with substantial morbidity and mortality. Hence, the timely identification of individuals with elevated blood pressure and early-life blood pressure management could serve as a crucial strategy to mitigate the risk of cardiovascular disease and mortality in adulthood.
