Bedside cardiovascular maternal interrogation in the first trimester to predict different phenotypes of hypertensive disorders in pregnancy

9OBJECTIVE: The aim is to evaluate if maternal cardiovascular indices, in the first trimester of pregnancy, might be useful to differentiate women who develop different hypertensive disorders of pregnancy (HDP). STUDY DESIGN: Method: 1399 pregnant women attending screening for chromosomal aneuploidies were recruited. The following parameters were measured: Doppler Velocimetry of uterine arteries; Peripheral blood pressure; Aortic Pressure derived from applanation tonometry. Primary outcome were: women who developed HDP associated with newborns with an appropriate weight for local gestational age standards (AGA) and women that developed HDP associated with a newborn weight below the 10th centile (SGA). RESULTS: Mean UtA PI was significantly higher in the HDP-SGA compared with controls. HDP-AGA showed a higher rate of family history of hypertension and a higher BMI. In HDP-AGA Brachial and Aortic mean pressure were higher than controls. The most significant contributors for all forms of HDP were mean UtA PI for HDP-SGA and mean arterial blood pressure for HDP-AGA. The multivariate logistic regression for HDP-SGA shows an AUC 0.88, whereas the AUC for the prediction of HDP-AGA group was 0.71. CONCLUSION: HDP-SGA were characterized by significantly higher values of UtA-PI, whereas HDP-AGA by mean aortic and brachial pressure and risk factors for endothelial dysfunction.reservedmixedDi Martino, Daniela Denis; Stampalija, Tamara; Rosti, Eleonora; Casati, Daniela; Signorelli, Valentina; Zullino, Sara; Mastroianni, Cristina; Quadrifoglio, Mariachiara; Ferrazzi, EnricoDi Martino, Daniela Denis; Stampalija, Tamara; Rosti, Eleonora; Casati, Daniela; Signorelli, Valentina; Zullino, Sara; Mastroianni, Cristina; Quadrifoglio, Mariachiara; Ferrazzi, Enric
