[The burden of blood pressure in the first half of pregnancy]

In the study, ambulatory blood pressure monitoring (ABPM) was estimated in 23 pregnant women in the first half of normal pregnancy and in 34 nonpregnant women. On the basis of ABPM, blood pressure load (BPL) were evaluated, as the exponent of blood pressure variability. In pregnant women BPL were lower in diastolic blood pressure component than those in nonpregnant women. It may testify stable character of diastolic blood pressure in healthy pregnant women. In the present decade the increasing importance of blood pressure variability is observed, because of its correlation with organ damage in hypertension. Authors emphasised the BPL examination necessity in healthy pregnant women and in pregnancy complicated by pregnancy induced hypertension (PIH).
