本文对88例短暂性脑缺血发作进行了1～7年的随访,运用寿命表方法分析了累积生存率、累积显效率和累积梗塞率。与国内外文献中其他3组比较,发现这4组死亡率的差异可用各组随访时间长短不同解释。本组病人未予特异治疗,但实际的梗塞发生率并不显著高于进行正规抗血小板治疗的美-加协作研究组。 88 cases of transient ischemic attack were followed up for 1 to 7 years, the life table method was used to analyze the cumulative survival rate, cumulative effective rate and cumulative infarction rate. Compared with the other three groups in the literature both at home and abroad, we found that the differences of the four groups of death rates could be explained by the length of follow-up of each group. This group of patients was not treated specifically, but the actual incidence of infarction was not significantly higher than that of the US-plus collaborative study group who underwent formal antiplatelet therapy.
