Preeclampsia and maladaptation to pregnancy: a role for atrial natriuretic peptide?
The majority of women with a history of preeclampsia have either an underlying thrombophilic disorder or a vascular disorder. In this study, we tested the hypothesis that only the latter condition predisposes for abnormal hemodynamic adaptation to pregnancy. ⋯ The hemodynamic adaptation to pregnancy in the HYPERT and NONTHROMB subgroups differs from that in THROMB and controls by an early pregnancy rise in alpha-atrial natriuretic peptide. As a consequence, the early pregnancy plasma volume expansion in the NONTHROMB and HYPERT subgroups is less than in normal parous controls.
