Assiut University
Brief Summary

The aim of our study is to evaluate the effect of PE and FGR on fetal cardiac function. Pregnancies with preeclampsia and FGR, and preeclampsia with normal fetal growth are evaluated by echocardiography and compared with uncomplicated pregnancies.

Detailed Description

Preeclampsia (PE) represent a major concern in public health, affecting 2-8% of all pregnancies and considered one of the leading causes of perinatal morbidity and mortality. Fetal growth restriction (FGR) ia also a common health problem affecting about 5-10% of all pregnancies and commonly associates with preeclampsia . It is estimated that 20% of cases of PE present with FGR and about 50% of early-onset FGR cases will eventually coexist with PE .

Both syndromes share some pathophysiologic features, with a variable involvement of placental insufficiency and cause fetal cardiovascular remodeling and adaptations . Fetal adaptations as metabolic and cardiovascular programming occur in response to adverse intrauterine conditions as PE and FGR . Offspring from preeclamptic pregnancies showed cardiac structural and functional changes and greater blood pressure in childhood and adolescence .

Most of the studies on FGR included pregnancies complicated by PE and vice versa, which fails to adequately assess the independent effect of each condition on the fetal cardiac functions.

GroupInterventionDescription
Patients with preeclampsiaUltrasoundFetal ultrasound( echocardiography).Measurements will be performed using conventional pulsed-wave Doppler and M mode cross sectional image of the fetal thorax at the level of the 4-chamber view with an apical projection of the heart is obtained. Measurements of the ventricle at diastole and systole are obtained, and using the relationship between these measurements, calculations are performed to determine the ejection fraction (EF) (\[diastole measurement-systole measurement\]/diastole) measurement and shortening fraction ( SF) for both right \& left ventricles. Assessment of ventricular diastolic function through measuring E-wave (early ventricular filling) and A wave (active atrial contraction - late ventricular filling) peak velocities and the ratio between them (E/A ratio) as an index will be performed for both mitral valve (MV) and tricuspid valve (TV)
