title: [Blood pressure variability on the basis of 24-hour ambulatory blood pressure monitoring in a group of healthy persons].
abstract: The aim of our research was to test twenty four hour variabilities of blood pressure (BPV) in a group of healty persons. The group consisted of 125 healthy persons (58 men and 67 women) 14-70 years old (mean age 33.8 +/- 14 years). Standard deviation (SD) from average blood pressure and the presence and size of night fall of arterial blood pressure (dippers and non dippers) was tested as parameters of BPLV. Average twenty four hours systolic blood pressure (SBP) in all the group was 119.7 +/- 10.9 mm Hg (123.5 +/- 11.5 mm Hg during the day and 106.2 +/- 12.2 at night). Average twenty-four-hour diastolic blood pressure (DBP) in all group was 71.9 +/- 9.0 mm Hg (74.0 +/- 9.5 during the day, 62.8 +/- 9.3 mm Hg at night). The mean SD of 24-hour SBP was 15.2 +/- 3.5 mm Hg (13.6 +/- for day's hours and 11.2 +/- 4.1 mm Hg at night). The mean SD of 24-hour DBP was 13.0 +/- 2.6 mm Hg (12.1 +/- 2.8 at the day and 9.8 +/- 3.0 at night). There were no correlation between and SBP SD or DBP SD and sex, age of the investigated patients and their membership to dipper and nondipper group. The positive correlation between SBP and and its SD was observed in the group with SBP below 120 mmHg and the same was ascertained in group of people below 40 years of life. Average night fall of SBP was 17.17 +/- 9.42 mm Hg (13.9 +/- 7.4%). Average night fall of DBP was 11.70 +/- 6.91 mmHg (15.7 +/- 8.8%) Nondippers ascertained 28.8% of all group. (32.8% of women and 24.4% of men). Multivariate analysis showed relationship between membership to dipper group and mean diurnal systolic blood pressure (odds ratio 0.93, 95% confidence interval 0.89-0.97, p = 0.02) and between low value of systolic pressure SD during all day monitoring and mean diurnal systolic blood pressure (odds ratio 0.94, 95% confidence interval 0.89-0.99, p = 0.02). Variability of arterial blood pressure is sex, age and mean diurnal pressure related. Parameters of short and long term variability are characterised by large repeatability. Our variability values can be voice in discussion on the norms in analysis of normal blood pressure patients.
