title: Atrial natriuretic peptide plasma level remains unchanged in various hypertensive disorders of pregnancy.
abstract: The decreased volume of maternal extracellular fluid in preeclamptics may result in a different rate of atrial natriuretic peptide secretion and thus affect its plasma levels. Our objectives were to determine whether there was a difference in plasma levels of atrial natriuretic peptide in the various hypertensive disorders of pregnancy. Forty-nine pregnant women in the third trimester of pregnancy were evaluated: 21 with preeclampsia, 17 with chronic hypertension during pregnancy and 11 normotensives. The atrial natriuretic peptide concentration was 13.9 +/- 5.9 pg/ml, 17.8 +/- 13.5 pg/ml and 16.7 +/- 7.4 pg/ml in the preeclamptics, chronic hypertensives and normotensives, respectively. The differences between the three groups were not statistically significant. Atrial natriuretic peptide plasma levels remained stable in the various hypertensive disorders of pregnancy.
