Transient ischemic attack (TIA) provides a golden opportunity for stroke prevention. TIA should be treated as a medical emergency with prompt investigations to determine the mechanism of ischemia and subsequent preventive therapy. The risk of stroke after TIA is estimated to be 10%-20% in the first 90 days. The risk is time-dependent with 50% of the risk accruing in the first 48 hours. In this review, we describe the diagnosis and management of TIA, introduce new concepts in TIA and suggest that all patients with significant TIA should undergo rapid investigation and management to prevent stroke.
短暂性脑缺血发作(TIA)为预防中风提供了一个绝佳机会。TIA应作为医疗急症进行治疗,需迅速进行检查以确定缺血机制并随后进行预防性治疗。TIA后90天内中风风险估计为10%-20%。该风险具有时间依赖性,50%的风险在前48小时内累积。在本综述中,我们描述了TIA的诊断和管理,介绍了TIA的新概念,并建议所有有显著TIA的患者应接受快速检查和管理以预防中风。
