Carotid Ultrasound-based Assessment of Maternal Hemodynamics to Guide HYpertension Treatment in PREgnancy - Pilot Study

Carotid ultrasound-based assessment of maternal hemodynamics to guide HYpertension treatment in PREgnancy - Pilot study - CHYPRE-pilot Healthy pregnancy is associated with significant physiological hemodynamic changes that are critical for maternal adaptation and health. Insufficient adaptive changes can lead to pregnancy disorders such as preeclampsia. Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal and foetal morbidity and mortality. Assessment of maternal hemodynamic alterations can improve management strategies by better risk stratification of pregnant women. Current methods for maternal hemodynamic measurement involve transthoracic echocardiography, requiring expert consultation with a cardiologist and highly trained staff. Simpler techniques like carotid ultrasound based hemodynamic assessment can potentially provide an easy-to perform alternative, requiring minimal training.
