Masked Hypertension Assessed by Ambulatory Blood Pressure Versus Home Blood Pressure Monitoring: Is It the Same Phenomenon?
Key result
Home blood pressure monitoring detected a similar proportion of masked hypertension compared to ambulatory monitoring (11.9% vs 14.2%), with moderate diagnostic agreement (kappa 0.56).
Why the study?
Does home blood pressure monitoring agree with ambulatory blood pressure monitoring in the diagnosis of masked hypertension in patients referred to an outpatient clinic?
Population
438 subjects referred to an outpatient hypertension clinic.
Comparison
Home blood pressure (HBP) monitoring (4 days) vs Ambulatory blood pressure (ABP) monitoring (24 h)

Implication
Supports home BP monitoring as a practical option for masked hypertension in clinic referrals; leaves open need for outcome-based validation.

Does home blood pressure monitoring agree with ambulatory blood pressure monitoring in the diagnosis of masked hypertension in patients referred to an outpatient clinic?
P
Population
438 subjects referred to an outpatient hypertension clinic (mean age 51.5 +/- 11.6 years; 59% men and 41% women, 34% treated and 66% untreated).
I
Intervention
Home blood pressure (HBP) monitoring (4 days)
C
Comparator
Ambulatory blood pressure (ABP) monitoring (24 h)

Outcome

Main Result
Effect estimate: kappa 0.56
Absolute Event Rate: 11.9% vs 14.2%
Both ambulatory and home blood pressure monitoring detect similar proportions of masked hypertension and are appropriate methods for its diagnosis.

Stergiou et al. (2005) conducted an observational in Masked hypertension (n=438). Home blood pressure (HBP) monitoring vs. Ambulatory blood pressure (ABP) monitoring was evaluated on Diagnosis of masked hypertension (kappa 0.56). Home blood pressure monitoring detected a similar proportion of masked hypertension compared to ambulatory monitoring (11.9% vs 14.2%), with moderate diagnostic agreement (kappa 0.56).
