Results of 24-hour blood pressure monitoring in children and adolescents with elevated blood pressure during random measurements
Three hundred and eighty children and adolescents (286 boys and 102 girls) aged 7 to 18 years who had elevated blood pressuie (BP) - BP elevation being recorded at least 3 times on individual visits to a doctor - were examined 24-hour BP monitoring was made in all the examinees to confirm the presence of arterial hypertension (AH) and to specify its grade Analyzing the find mgs indicated that in 24% of the examinees, BP values were in the normal range (daily pressure load was less than 25%), 43% of the patients were found to have labile AH (daily pressure load was within 25-50%), stable hypertension (daily pressure load was more than 50%) was recorded in 33% The predominant form of arterial hypertension m children with stable AH (daily pressure load was more than 50%) was a steady-state increase in systolic BP Reduced nocturnal BP dipping was observed in 29% of all the examinees The study of BP variability indicated a significant increase in this parameter depending on the degree of hypertension burden Thus, the findings suggest that the examinees had increased vascular tonicity and the impairments associated with the development of cardiovascular events m adulthood
