【摘要】 目的探讨急性心肌梗死患者血液流变学改变特性。方法对105例急性心肌梗死患者的多项血液流变学指标进行相关分析。结果急性心肌梗死患者血液流变学各项指标与对照组比较,差异均有显著性,全血粘度特别是低切粘度,明显高于对照组,与对照组比较P<0.001,血浆粘度、红细胞压积、纤维蛋白原、血小板聚集率、红细胞聚集指数均有不同程度的升高,而红细胞的变形能力则显著下降P<0.01。结论急性心肌梗死患者血液流变学改变的发生与高粘稠血症、血小板聚集的明显增加、血浆粘度的增加、高纤维蛋白原有着密切关系,是造成心肌缺血、缺氧的重要病因之一。更多还原

【Abstract】 Objective To evaluate the acute myocardial infarction patients’ change characteristics of blood rheology.Methods 105 patients had acute myocardial infarction,whose some indexes of blood rheology were analyzed retrospectively.Results The acute myocardial infarction patients’ some indexes of blood rheology get change,there was obviously difference between the control group and the study group.In study group,whole blood viscosity was obviously higher than the study group(p<0.001).Plasma viscosity,packed cell volume,fibrinogen,platelet aggregation rate and hemo agglutinnation index were all higher.And red cells’metamorphotic ability was obviously decreased(p<0.001).Conclusion The acute myocardial infarction patients’ change of blood rheology were related to hyperviscosity syndrome,plateletagg regation increase,blood viscosity increase,fibrinogen increase.It was one of important causes of myocardial ischemia and oxygen deficit.更多还原
