Implication

Clinic readings may overestimate 24-h BP in mild hypertension; supports ambulatory monitoring evaluation but should not yet change practice.

Key Points

  • This research aims to compare blood pressure readings from various situations against average 24-hour values in untreated hypertensive patients.
  • Recorded blood pressure and heart rate at 15-min intervals for 24 hours in 60 untreated patients with mild essential hypertension.
  • Patients documented their daily activities during recording across five different situations: clinic, work, home, asleep, and overall average.
  • Analyzed the correlation between clinic readings and average 24-hour pressures.
  • Clinic pressures were higher than average 24-hour values, suggesting poor predictability for individual patients (P<0.05).
  • Pressure correlations were similar across clinic, home, work, and asleep conditions, with significant differences noticed in diastolic measurements during casual as compared to ambulatory monitoring.
  • For patients with clinic diastolic pressures of 90-104 mm Hg, average 24-hr pressures ranged from 75 to 100 mm Hg.

Structured PICO

Does 24-hour ambulatory blood pressure monitoring provide different blood pressure values compared to clinic readings in untreated patients with mild essential hypertension?

P
Population
60 untreated patients with uncomplicated mild essential hypertension
I
Intervention
24-hour ambulatory blood pressure monitoring (recorded at 15-min intervals)
C
Comparator
Clinic blood pressure readings and previously obtained casual readings
O
Outcome
Blood pressure and heart rate variations across five situations (clinic, work, home, asleep, and 24-hr average)surrogate

Ambulatory blood pressure monitoring reveals that clinic readings often overestimate average 24-hour blood pressure, highlighting its utility in evaluating mild hypertension.
