[Gynecology-obstetrics. Contribution of maternal haemodynamics during pregnancy]

Pregnancy leads to a progressive adaptation of the maternal vascular and cardiac systems. Blood pressure is an imperfect indicator of this adaptation, as it reflects cardiac output, vascular resistance, and circulatory volume. Increasingly, studies show that poor hemodynamic adaptation can predict or accompany maternal and/or foetal complications. During pregnancy follow-up, assessing hemodynamic parameters could help identify patients at-risk and personalize their care. In obstetric emergencies, understanding the maternal hemodynamic status can improve clinical management.
