[Atrial natriuretic peptide in normotensive pregnancy: concentrations in physical stress, pre- and postpartal and in the umbilical cord].
The concentrations of the atrial natriuretic peptide (ANP) during the 3rd trimester of pregnancy (n = 54), the 1st, 2nd, and 3rd day post partum and in 10 non pregnant females were measured and compared. Moreover ANP was determined in the umbilical cord (artery n = 10, vein n = 48) and the influence of exercise on the concentration of ANP in pregnant (n = 10) and non pregnant women (n = 10) was analyzed. There was no significant difference of the ANP-values measured in non pregnant patients and during the third trimester (100 +/- 57 vs. 97 +/- 27 pg/ml). On the 3rd day post partum a significant rise of ANP was noted (1st day post partum 78 +/- 43, 3rd day post partum 102 +/- 46, 5th day post partum 84 +/- 40 pg/ml). During physical exercise the concentration of ANP increases significantly in pregnant (103 +/- 45 vs. 120 +/- 57 pg/ml, p < 0.05) as well as in non pregnant females (97 +/- 27 vs. 111 +/- 39 pg/ml, p < 0.05). In arterial blood samples from the umbilical cord the concentration of ANP was higher than in venous cord blood (62 +/- 34 vs. 51 +/- 28 pg/ml, p > 0.05).
