  • Title: [Changes in blood visco-elasticity in normal pregnancy and pregnancy induced hypertension].
    Author: Wang LY.
    Journal: Zhonghua Fu Chan Ke Za Zhi; 1993 Dec; 28(12):711-3, 758. PubMed ID: 8137638.
    Abstract:
    The study was designed on blood visco-elasticity of normal pregnant and pregnancy induced hypertension (PIH) women. Visco-component (eta'), elastic-component (eta") and storage modulus (G') decreased significantly during the 1st trimester of pregnancy, but rose slowly in the 3rd trimester. eta' was the most significant and it revealed an inverse correlation with neonate birth weight. There were no changes of eta', eta" and G' in women with mild PIH, but they rose markedly in groups with moderate and severe PIH. In conclusion, abnormal blood viscosity and elasticity, i.e. an increase of RBC aggregation and/or a decrease of RBC deformability, may be an important abnormal hemorheological changes in PIH.
