研究了老年高粘滞综合征病人口服低分子肝素、未分级肝素胶囊前后血流变学各项指标的变化。结果低分子肝素组全血高切粘度、全血低切粘度、血浆粘度、红细胞聚集指数、血沉等均显著降低;未分级肝素组除血沉显著降低外,余各项指标均呈降低趋势,但无统计学意义。低分子肝素胶囊口服后可有效地改善血流变学指标,这对防治心脑血管动脉粥样硬化疾病具有重要意义。 The changes of various indexes of hemorrheology in elderly patients with high-viscosity syndrome before and after oral administration of low-molecular-weight heparin and unfractionated heparin were studied. Results In low molecular weight heparin group, the indexes of whole blood high shear viscosity, whole blood low shear viscosity, plasma viscosity, erythrocyte aggregation index and erythrocyte sedimentation rate were all significantly decreased. However, the indexes of hemodilution decreased obviously in unfractionated heparin group, No statistical significance. Low molecular weight heparin capsules can effectively improve hemorrheological indicators after oral administration, which is of great importance in the prevention and treatment of cardiovascular and cerebrovascular atherosclerotic diseases.
