Preeclampsia (PE) is a multisystemic disorder unique to human pregnancy and responsible for about 44,000 maternal deaths worldwide. This disease is associated with multiple complications for both mother and fetus; however, its etiology is not totally clear and it has therefore been difficult to define valid prediction strategies. PE is a complex disease and it shares different risk factors with cardiovascular disease, such as obesity, hypertension, insulin resistance and dyslipidemia, evidencing that the presence of disturbances in lipid and apolipoprotein levels are associated with increased lipid peroxidation * Correspondencia: Dra.
