目的调查研究短暂性脑缺血发作进展至脑梗死的相关危险因素,为脑梗死的预防工作提供依据。方法 3个月内有首次TIA发作的脑梗死患者102例和3个月内有首次TIA发作病史、但是未进展为脑梗死的306例TIA患者进行回顾性病例对照研究。结果患有糖尿病、患有高血压、患有冠心病、TIA发作时间≥30 min、3个月内发作次数组≥6次是短暂性脑缺血发作进展至脑梗死的危险因素。结论对有进展至脑梗死危险因素的TIA患者应采取积极的治疗和预防,以降低或避免脑梗死的发生。
Objective To investigate the related risk factors of transient ischemic attack to cerebral infarction and provide the basis for the prevention of cerebral infarction. METHODS: A retrospective case-control study was performed in 102 patients with cerebral infarction with first TIA episode within 3 months and the first episode of TIA within 3 months but without progressing to cerebral infarction. Results Patients with diabetes mellitus, high blood pressure, coronary heart disease, TIA onset ≥30 min and episodes of ≥6 within 3 months were the risk factors of transient ischemic attack to cerebral infarction. Conclusion TIA patients who have progressed to risk factors of cerebral infarction should take active treatment and prevention to reduce or avoid the occurrence of cerebral infarction.
