一般认为 ,年轻人缺血性卒中及暂短性缺血发作 (ＴＩＡ)的预后良好 ,然年轻人脑缺血的年发生率约6 /10万。虽然仅占全部卒中的 1% ,但对数年潜在的死亡和社会经济损失有相应的影响。现有的前瞻性研究报告 ,年卒中死亡率与复发率为 1%～ 2 6 % ,大血管卒中患者的长期死亡率较高 It is generally believed that the prognosis of ischemic stroke and transient ischemic attack (TIA) in young people is good, but the annual incidence of cerebral ischemia in young people is about 6/10 million. Although accounting for only 1% of all strokes, it has a corresponding impact on the number of years of potential death and socio-economic losses. Current prospective studies have shown that the annual mortality and relapse rate of stroke is 1% ~ 26%. The long-term mortality of patients with macrovascular stroke is higher
