目的观察分析短暂性脑缺血发作(TIA)发展至脑梗死的危险因素,总结其临床经验和临床意义。方法选取该院收治的TIA患者143例,其中TIA发展至脑梗死的患者55例,对其发病的各种危险因素进行调查与总结分析,观察二者的相关性。结果椎-基底动脉系统TIA、发生TIA后至发生脑梗死的时间>30min、TIA的发作频率>3次/24h、首次TIA发作的持续时间>2h、首次TIA发作到得到有效救治的时间<6h均为TIA发展至脑梗死的独立危险因素,与非上述情况相比,脑梗死的发生率显著升高,差异有统计学意义(P<0.05)。结论临床上应对TIA发展至脑梗死的各项危险因子给予高度关注,尽量避免和减少,以降低脑梗发生率,有重要的临床意义。
Objective To analyze the risk factors for the development of transient ischemic attack (TIA) to cerebral infarction and summarize its clinical experience and clinical significance. Methods TIA patients admitted to the hospital 143 cases, including TIA to cerebral infarction in 55 patients, the incidence of various risk factors were investigated and analyzed, to observe the correlation between the two. Results The TIA of the vertebrobasilar artery system, the time from onset of TIA to cerebral infarction> 30 minutes, the frequency of TIA episodes> 3 times / 24h, the duration of the first TIA episode> 2 hours, the time to effective treatment for the first TIA episode <6 hours Were independent risk factors for the development of TIA to cerebral infarction. Compared with the above cases, the incidence of cerebral infarction was significantly increased (P <0.05). Conclusion The clinical response to the development of TIA to risk factors for cerebral infarction give great attention to avoid and reduce as much as possible to reduce the incidence of cerebral infarction, has important clinical significance.
