Key result
ABPM records ~19 mm Hg lower mean systolic blood pressure than manual measurements in young men.
Why the study?
Ambulatory blood pressure monitoring has been found superior to outpatient manual blood pressure measurements for predicting clinical outcomes, but its use in young subjects found hypertensive before high altitude induction was studied.
Does 24 hours ABPM reduce the recorded blood pressure compared to manual OBPM in young patients found to be hypertensive during routine examination?
Observational (n=100)
No
Does 24 hours ABPM reduce the recorded blood pressure compared to manual OBPM in young patients found to be hypertensive during routine examination?
Absolute Event Rate: 123.92% vs 143.33%
ABPM yields significantly lower blood pressure readings than manual OBPM in young individuals suspected of hypertension, potentially preventing unnecessary labeling and treatment.
ABPM may avoid overdiagnosis of hypertension in young men; hypothesis-generating for prospective trials before changing diagnostic practice.
Background: Ambulatory blood pressure monitoring (ABPM) measurements has been found to be superior to Outpatient Department (OPD) blood pressure measurements (OBPM) for predicting clinical outcomes. There have been various indications of ABPM like to exclude white coat hypertension, evaluation of symptomatic hypotension and hypertension, pregnancy induced hypertension etc. We studied use of ABPM in evaluation of young subjects who were found to be hypertensive in OBPM.Methods: This prospective study was performed at Command Hospital, Kolkata, India from December 2017 to November 2019.This study had a total of 100 subjects. All patients were young healthy individuals and found to have high blood pressure (BP) readings during routine examination done before induction to high altitude areas (>9000 feet). All subjects who were found to be hypertensive in OBPM were evaluated with 24 hours ABPM at least one week after cessation of all medications. Data expressed as the mean±SD. Comparisons of (a) the peripheral hospital mean systolic and diastolic BP over 01 week and (b) 24 hours mean ABPM. Results: In the study, the Mean Systolic BP was 143.33±11.82 with corresponding ABPM 123.92±13.17 which is statistically significant. The mean diastolic BP was 87.30±7.20 mm with corresponding ABPM as 71.55±4.11 MAP in manual blood pressure is 125.55 mm and 103.6 mm in ABPM. The results are highly significant.Conclusions: The study concludes that automated BP recordings may provide a more accurate estimate of a patient's BP status and may prevent unnecessary labelling of young patients as hypertensive.

Sharma et al. (2020) conducted an observational in Hypertension (n=100). Ambulatory blood pressure monitoring (ABPM) vs. Manual outpatient blood pressure measurement (OBPM) was evaluated on Mean systolic blood pressure. Ambulatory blood pressure monitoring recorded significantly lower mean systolic (123.92 vs 143.33 mm Hg) and diastolic (71.55 vs 87.30 mm Hg) blood pressures compared to manual outpatient measurements in young men.
