[Antihypertensive therapeutic effect. Comparison of their evaluation using clinical and ambulatory measurements of arterial pressure. Preliminary study].
The aim of this preliminary report is to compare the evaluation of the antihypertensive drug effect, during a controlled trial, using casual measurements and 24 hr B.P. monitoring. 20 patients (16 males, 4 females 55 +/- 10 years old) with primary hypertension (WHO stage I or II) were included with a diastolic blood pressure greater than or equal to 100 mmHg (mean blood pressure from three clinical readings). Casual B.P. and B.P. monitoring (Spacelabs - 4 measurements per hour during a 24 hr period) were established before and after the end of the placebo run in period (one placebo tablet given once daily at 8 h-8 h 30 a.m. for 15 days). Overall sample data: The clinical B.P. decrease (167 +/- 16-109 +/- 7 before and 147 +/- 17-97 +/- 11 after treatment) is higher that the ambulatory B.P. decrease (148 +/- 15-101 +/- 8 before and 138 +/- 21-94 +/- 14 after treatment). Individual patient data: A clinical B.P. decrease (of at least 10 mmHg) was found in 17 patients for systolic B.P. and in 15 patients for diastolic B.P. A significant ambulatory B. P. drop decrease (p less than 0.05) was found in 11 patients for 24 hr systolic and diastolic B.P. The clinical and ambulatory responses to the treatment are in line in 14 patients, but differ in 3 instances. There is a little correlation (for the diastolic B.P.) and no correlation (for the systolic B.P.) between the clinical and the ambulatory B.P. decreases after treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
