Concordance Between the Systolic Foot-to-Apex Interval and the Auscultatory Method for Measuring Brachial Systolic Pressure in Pregnant Women With or Without Blood Pressure Disorders and Search for Markers of Arterial Stiffness in Pre-eclampsia.

The investigators hypothesize that the Systolic Foot-to-Apex Time Interval (SFATI) method is an accurate means of measuring systolic blood pressure in pregnant women at a risk of pre-eclampsia. As the presence of arterial calcifications only changes the concordance between the SFATI method and the auscultatory reference method if calcifications are very severe, it should make it possible to identify, at an early stage, those women with a higher risk of developing pre-eclampsia. This is a transversal study with monocentric prospective recruitment to evaluate a non-CE (Conformité Européenne) -marked medical device in a diagnostic situation.
