Preeclampsia is a systemic disorder of pregnancy characterized by widespread maternal endothelial dysfunction. Clinical manifestations of preeclampsia include placental hypoxia, hypertension, proteinuria and fluid retention. The condition is common and affects over 5% of all pregnancies, thus remaining a leading cause of maternal and fetal morbidity and mortality worldwide [1]. Pregnancies complicated by preeclampsia are associated with greater risk and earlier onset of cardiovascular disease in both mother and infant [2,3]. Preeclampsia originates in the placenta, as it may occur only in the presence of placenta or a hydatiform mole and resolves dramatically postpartum after the delivery of the placenta. Generalized endothelial dysfunction resulting in vasoconstriction and end-organ ischaemia is attributed in all of the clinical aspects of the maternal syndrome
