本文报告对314例短暂脑缺血发作(transientischemic attack,TIA)随访观察的结果。男168例、女146例。首次发病年龄17～77(平均49.2)岁,大多数为40～59岁,发生于颈动脉系统245例,椎-基底动脉系统69例。随访时间为2.8～13.2(平均7.8)年。随访期间15例患缺血性脑梗塞(IBI),发病率为4.8%,其中8例死亡;40例患急性心肌梗塞(AMI),发病率为12.7%,其中24例死亡。颈动脉系 TIA 组与椎-基底动脉系 TIA 组的 IBI 发病率和死亡率无显著差异,但前组 AMI 的发病率和死亡率高于后组(P<0.05)。抗凝治疗组 IBI 的发病率高于非抗凝治疗组(P<0.05),而两者的 IBI 死亡率及 AMI 发
This article reports the results of follow-up of 314 transient ischemic attacks (TIA). 168 males and 146 females. The first onset of age 17 to 77 (average 49.2) years, most of 40 to 59 years old, occurred in the carotid system 245 cases, vertebrobasilar system 69 cases. Follow-up time was 2.8 ~ 13.2 (average 7.8) years. During the follow-up period, 15 cases had ischemic cerebral infarction (IBI), the incidence rate was 4.8%, of which 8 cases died; 40 cases of acute myocardial infarction (AMI), the incidence was 12.7%, of which 24 died. The morbidity and mortality of IBI in TIA group and vertebrobasilar artery TIA group were not significantly different, but the morbidity and mortality of AMI in the former group were higher than those in the latter group (P <0.05). The incidence of IBI in anticoagulant therapy group was higher than that of non-anticoagulation therapy group (P <0.05), but the IBI mortality and AMI
