Predicting pregnancy-induced hypertension with dynamic hemodynamics.
OBJECTIVE
To study dynamic changes in the hemodynamic parameters in pregnant women during different weeks of gestation and to comprehend changes to the cardiovascular system in normal pregnant women and in patients with pregnancy-induced hypertension (PIH), with the object of finding predictors of pregnancy-induced hypertension.


METHODS
Radialis artery pulse waves of 132 pregnant women were examined from 10 weeks of gestation onward, and the subjects' hemodynamics were examined every 4 weeks.


RESULTS
In the women with PIH hemodynamic changes occurred earlier than the onset of disease and even presented in early pregnancy; there might be another mode, and there were factors disturbing the blood pressure modulating mechanism.


CONCLUSIONS
The prediction of PIH from the dynamic changes in hemodynamic parameters has significant implications for clinical practice.
