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.

Brachial systolic arterial blood pressure will be systematically taken with acquisition of the oscillometric curve for analysis and measurement with the SFATI system and simultaneous electronic recording of the Korotkoff sound (auscultatory method) and a search for SFATI arterial stiffness markers for all patients. Brachial systolic arterial blood pressure will be measured with the help of a cuff equipped with a Biopac SS30L electronic stethoscope and a MA-300 phonocardiographic microphone, placed side-by-side immediately downstream from the brachial occlusion cuff. The various signals (pneumatic cuff, oscillometric signal and Korotkoff sounds) will be digitalized by an MP35 system.

Brachial systolic blood pressure will be taken via the conventional oscillometric method, only for hospitalized women. Blood pressure will be measured on the same arm with the help of a conventional Dinamap-type automat (GE), with at least 2 minutes between the end of the first measurement and the start of the second inflation.

"Carotid to femoral and carotid to radial pulse wave velocity (Complior) will be systematically determined for hospitalized women and offered to all women seen for consultation.~Pulse wave velocity will be measured with the help of a Complior tonometric system (Alam Medical, Vincennes, France), with which the aorta and the arterial axes of the upper limb used to measure blood pressure can also be measured."
