White coat hypertension in children with elevated casual blood pressure

摘要: Abstract Objective: We reviewed our experience using ambulatory blood pressure monitoring (ABPM) in children referred to a hypertension clinic determine the frequency of pediatric white coat (WCH). Study design: WCH was defined by 3 different diagnostic criteria: (1) mean 24-hour (BP) less than Task Force–defined 95th percentile, (2) BP percentile from normative ABPM data, and (3) load (percentage readings during period exceeding percentile) 25%. Results: Clinic values were available 67 otherwise healthy who underwent ABPM; 51 had confirmed Force criteria. these patients with stated criteria 53%, 45%, 22%, respectively. Elevated found 52% (12/23) normal BP. Conclusion: These results suggest that many for casual elevation have even strict may help differentiate persistent hypertension, thereby avoiding unnecessary evaluation identifying most likely benefit early intervention.
