[Fetal growth in pregnant women with chronic hypertension].

This study represents a retrospective analysis of pregnancies with chronic arterial hypertension and their outcomes. The aim was to evaluate the influence of arterial hypertension on 101 essential and 109 cases of secondary hypertension in comparison to the control group consisting of 499 normotensive pregnancies. According to the obtained data, 27.7% of the women with chronic hypertension had proteinuria, 61% had bacteriuria and 58.6% had superimposed EPH gestosis. The occurrence of EPH gestosis among the controls was 5.6%, that is significantly less than in the experimental group (X2 = 282.8%; p < 0.001). The outcomes of pregnancies associated with chronic hypertension were: 19% preterm deliveries compared to the controls in which only 9.2% preterm deliveries occurred (X2 = 14.4; p < 0.001). Newborns from pregnancies with essential hypertension were significantly heavier, weighing 3177 +/- 734 g, than those from pregnancies with secondary hypertension, which weighted 2578 +/- 932 g. Perinatal mortality was higher in the study group and significantly higher in the pregnancies with associated secondary hypertension (30.3%) than in pregnancies associated with essential hypertension (15.8%).
