ملخص

The objective of this study was to examine whether aortic stiffness, as assessed by pulse wave analysis, could reliably discriminate between normal and hypertensive pregnancies. One hundred pregnant women were studied: five with severe pre-eclampsia, 27 with gestational hypertension, 14 with chronic hypertension and 54 with normal pregnancy. Central hemodynamic parameters were obtained by an applanation tonometry and included central aortic systolic blood pressure (CSBP), central aortic diastolic blood pressure (CDBP), augmentation pressure (AP), augmentation index (AIx), AIx corrected to a heart rate of 75 (AIx@75) and time to reflection (Tr). All measures of aortic stiffness, including AP, AIx and AIx@75 were significantly higher in women with gestational hypertension and pre-eclampsia compared with normal pregnancies and women with chronic hypertension (p < 0.05 for all comparisons). There were no significant differences between normal pregnancies and women with chronic hypertension (p > 0.05 for all comparisons). Tr was significantly shorter in women with pre-eclampsia and gestational hypertension compared with normal pregnancies (p < 0.05). Aortic stiffness, as assessed by pulse wave analysis, is significantly increased in women with pre-eclampsia and gestational hypertension but not in treated women with chronic hypertension. Pulse wave analysis has a potential as a screening tool in women at high risk for pre-eclampsia. The final role of this method should be determined in prospective studies.
