Changes in plasmaconcentration of ANP and aldosterone in normal pregnancy and pregnancy complicated by pre-eclampsia.
Changes in plasmaconcentration of ANP in normal pregnancy and pregnancy complicated by pre-eclampsia were examined and compared to non-pregnant controls. The maternal plasma concentration increased gradually during normal pregnancy but values did not deviate significantly from non-pregnant women. A further increase was demonstrated post partum. In pre-eclampsia maternal plasma ANP levels increased significantly compared with normal gravida at the same gestational age and non-pregnant controls. After delivery ANP decreased significantly. Non correlation between ANP and aldosterone were found in either normal pregnancy nor pregnancy complicated by pre-eclampsia. It is not yet clear how important ANP is for the regulation of blood pressure and sodium and water balance during normal pregnancy and pregnancy complicated by pre-eclampsia.
