In the study herein, 100 pregnant women were evaluated; they were distributed in the following groups: The group of pregnant women diagnosed with HTN at the time of hospital admission – including 50 pregnant women, of which 16 pregnant women presented medium and severe forms of preeclampsia and 34 pregnant women with pregnancy-induced hypertension and 50 pregnant women with normal pregnancy evolution as control group. We have performed hematological and biochemical tests, using serum samples from all analyzed patients and measured the serum concentrations of sFlt-1 and PlGF angiogenic factors. We found a significant correlation between the value of the arterial blood pressure, the proteinuria, the serum creatinine and the AST, on one hand, and the sFlt-1/PlGF ratio, on the other hand. The ROC curve has emphasized the fact that the proteinuria (AUC = 0.849), the AST (AUC = 0.664), the value of the arterial blood pressure SBP/DBP (AUC = 0.683/0.631), the serum creatinine (AUC = 0.674) and the sFlt-1/PlGF ratio, at a cut off value = 200, are effective preeclampsia predictors. Similarly, statistically significant increase (p = 0.001) of the sFlt-1 serum concentration in case of the pregnant women from the PE group (14365±6464 pg/mL) and from the PIH group (9892±8443 pg/mL), compared to the control group (3278±1444 pg/mL) and, respectively, a significant decrease (p = 0.003) of the PlGF pro-angiogenic marker for the group of pregnant women suffering from preeclampsia (119.30±56.63 pg/mL) and from PIH (129.12±21.41 pg/mL), compared to the control group (327.57±59.62 pg/mL). The results obtained within this research show that sFlt-1/PlGF ratio represents an effective preeclampsia predictor, confirming the fact that the study of the angiogenic factors may help to analyze the stratification of the risk degree in HTN pregnant women.
