Design: The aim of our study was to established possible a correlation between Holter blood pressure measurements and BP levels measured incidentally by the medical personnel. We also tried to evaluate usefulness of ABPM in monitoring intensification of the hypertension.
Materials and methods: The research was performed on 57 pregnant women where pregnancies were complicated by hypertension (PIH or chronic hypertension). All patients were divided into four groups conforming with JNC VI protocol according to BP level measured in the time of the admission to hospital. Therefore circadian blood pressure profile was done by using ABPM SpaceLab device. After that BP load indicator was estimated in each group to assess intensification of the disease. However, we compared those results between groups by using t-Student test (p < 0.05).
Results: We qualified 22 patients to group 0 with SBP = 129,45 + 6.31 mmHg and DBP = 80.59 + 5.45 mmHg in the time of admission. There were 21 pregnant women with mild hypertension (group I SBP = 144,14 + 7.32 mmHg, DBP = 93.14 + 4.52 mmHg), moderate (group II, N = 8 with SBP = 153,88 + 5.54 mmHg and DBP = 101,34 + 3.78 mmHg) and severe hypertension (group III, N = 6 with SBP = 175,83 + 33.23 mmHg, DBP = 121 + 11.92 mmHg). BP load value measured in group 0 was 14.57 + 21.3% of SBP and 13.92 + 22.99% of DBP inappropriate results. In group I was found SBP 24.91 + 30.3%, DBP 23.12 + 26.01%, group II SBP 38.11 + 33.66%, DBP 26.31 + 22.75% and in group III SBP 59.3 + 38.76% and DBP 61.37 + 35.72%, respectively.
Conclusions: Only between the group with normal blood pressure and the group with severe hypertension the obtained results were statistically significant (p < 0.05). We've also found a statistical correlation between BP values measured in the time of admission to the hospital and BP load indices in each group.
