Why the study?

How do ambulatory blood pressure patterns compare to casual blood pressure measurements in healthy normotensive men?

Population

34 healthy normotensive men

Comparison

Noninvasive automated ambulatory BP monitoring vs Casual BP measurements

Design

Cross-sectional

Follow-up

24 hours (whole-day)

Authors

Discussion

Member takes

Implication

Casual BP may misclassify daytime and nighttime values in normotensive men; leaves open whether ambulatory monitoring refines risk stratification.

Key Points

Characterize 24-hour ambulatory blood pressure profiles and evaluate the occurrence of transient elevated blood pressure readings in clinically normotensive men.
Conducted automated, noninvasive ambulatory blood pressure monitoring over a full day in 34 healthy normotensive men.
Compared daytime and nighttime blood pressure averages against standard casual clinic measurements and assessed the influence of age and family history of hypertension.
Daytime blood pressures (128 ± 12 / 80 ± 7 mm Hg) were significantly higher and nighttime averages (109 ± 11 / 67 ± 9 mm Hg) were significantly lower than casual readings (119 ± 13 / 76 ± 9 mm Hg).
Systolic blood pressure exceeded 140 mm Hg in an average of 15.6% of readings per participant, and diastolic pressure exceeded 90 mm Hg in 14.4% of readings, with 6 of 34 men exceeding these thresholds on more than 25% of readings.
Elevated systolic readings were not associated with age but occurred more frequently in men with a family history of hypertension than in those without (24% vs. 9%).

Outcome

Blood pressure patterns (daytime vs nighttime vs casual BP)surrogate

Ambulatory BP monitoring in normotensive men demonstrates significant diurnal variation and frequent transient elevations, which are more common in those with a family history of hypertension.
