Key result
Variable nocturnal blood pressure dipping status was observed in 44% of subjects over 12 months, demonstrating that classifying patients based on a single recording is unreliable.
Why the study?
Is nocturnal blood pressure dipping status reproducible over time in untreated hypertensive and normotensive subjects?
Population
79 subjects (69 untreated hypertensives and 10 normotensives)

Single ABPM recordings may misclassify dipping status; leaves open whether repeated monitoring improves risk stratification.

Is nocturnal blood pressure dipping status reproducible over time in untreated hypertensive and normotensive subjects?
Classifying hypertensive patients into dippers or nondippers based on a single ambulatory blood pressure recording is unreliable due to significant intrasubject variability linked to sleep quality.
Manning et al. (2000) conducted a cohort in Hypertension (n=79). Ambulatory blood pressure monitoring was evaluated on Reproducibility of dipper status. Variable nocturnal blood pressure dipping status was observed in 44% of subjects over 12 months, demonstrating that classifying patients based on a single recording is unreliable.
