Central Blood Pressure

The aim of the study is to check standard screening blood pressure in the arm and central blood pressure, the blood pressure at the heart in pregnant women. The standard brachial pressure is routinely monitored throughout pregnancy, however it is not sensitive enough to distinguish preeclampsia from other types of hypertension or to predict preeclampsia in those at risk. Central aortic pressure monitoring has become a valuable clinical tool and preliminary studies suggest that measuring of central blood pressure may be better predictor of preeclampsia. It is non invasive and doesn't require undressing. It involves using a standard blood pressure cuff placed around the thigh, checking carotid pulse and pressure with an ultrasound and taking measurements of the person neck to torso. With this knowledge it will be a useful screening tool to identify these patients at higher risk and hopefully lead to closer monitoring, earlier treatment and reduced morbidity and mortality
