Objective |
To describe the epidemiology of reclassification of prehypertensive and unclassified adolescents by 2022 American Heart Association pediatric ambulatory blood pressure monitoring (ABPM) guidelines, and to evaluate the association of the new diagnostic categories with left ventricular hypertrophy (LVH).
Study design |
A single-center, retrospective review of ABPM reports from adolescents 13-21 years old, from 2015 through 2022, was performed. Adolescents with prehypertension or unclassified by 2014 guidelines were reclassified by 2022 definitions. Logistic regression models evaluated the association of reclassification phenotypes with LVH.
Results |
A majority of prehypertensive adolescents reclassified to hypertension (70%, n = 49/70). More than one-half (57%, n = 28/49) of the hypertension was isolated nocturnal hypertension, and 80% was systolic hypertension. Reclassification to hypertension was more common in males. The majority (55.6%) of unclassified adolescents were reclassified to normotension. No demographic or clinical variables were associated with reclassification categories. LVH was not associated with hypertension in the reclassified prehypertensive or unclassified groups.
Conclusions |
The 2022 ABPM guidelines clearly define blood pressure phenotypes. However, reclassification to hypertension was not associated with an increased odds of LVH. Because most prehypertensive adolescents reclassified as hypertensive by nighttime BPs alone, this study highlights the lowered threshold for nocturnal hypertension. Prospective studies in larger, well-defined cohorts are needed to describe better the predictive value of 2022 BP phenotypes for target organ damage.
