摘　　要：短暂性脑缺血发作(TIA),往往是脑卒中特别是脑梗塞的前期症状,与中医典藉所述中风先兆相近。本文测定了69例 TIA 患者和40例正常人的血小板聚集及血液流变学变化,结果发现 TIA 患者的血小板聚集功能显著增高(P<0.0001),同时其全血粘度、血浆粘度和纤维蛋白原均显著或非常显著高于正常对照。由此可见发作期间及时检测上述指标,对本病的诊断和治疗有重要价值。Transient ischemic attack(TIA)is a common cerebrovascular disease which maylead to cerebral infaction.In the past four years,hemorrheologic changes in 69 TIApatients have been investigated.Of them there were 44 males and 25 females,theaverage ages were 61.9 and 57.5 respectively.Compared with the normal control,the TIA patients showed marked platelet hyperaggregation,obvious elevation ofblood viscosity,plasma viscosity and fibrinogen,but the hematocrit and red bloodcell deformability index showed no significant difference.It was suggested thehemorrheology change of TIA might play an important role to the diagnosis andtreatment.
