本文采用放射免疫法对孕36～42用的正常孕妇和妊高征患者进行了血浆心钠素测定,共44例.结果:妊高征患者的血浆心钠素含量为174.1793±48.678pg/ml,显著低于正常晚孕孕妇的419.3873±156.5239pg/ml,P<0.01.其降低程度与病情的严重程度成正比.因此测定血浆心钠素不仅可作为诊断妊高征的客观依据,而且也可作为观察病情判断疗效的指标. In this paper, plasma atrial natriuretic peptide was measured by radioimmunoassay in 44 pregnant women with gestational hypertension and 36 ~ 42 gestational pregnant women.Results: The plasma atrial natriuretic peptide levels of patients with PIH were 174.1793 ± 48.678pg / ml , Which was significantly lower than that of normal pregnant women (419.3873 ± 156.5239pg / ml, P <0.01), which was directly proportional to the severity of the disease.Therefore, determination of plasma atrial natriuretic peptide not only serves as an objective basis for the diagnosis of PIH but also Can be used as indicators to determine the efficacy of judging the condition.
